    To know the trend of measures taken for global warming, conducted were overseas surveys, participation in academic society meetings, and literature surveys. The phaseout time of all ozone depleting substances responsible for the ozonospherial destruction was determined for both developed and developing countries in the 7th Meeting of countries which concluded the Montreal Protocol. As information on measures for protecting the ozonosphere, introduced was activities under United Nations Environment Programme (UNEP). New fluorine containing ethers were introduced as cleaning solvent which causes no ozonospherial destruction and is low in global warming index. Toxicity data were obtained on HFC-236ea and HFC-236fa which are promising substitutes in HCFC foaming and refrigerant fields. The paper introduced an outline of the 1st Meeting of countries which concluded the Framework Convention on Climate Change held in 1995. According to the report on the National Institute of Public Health and Environmental Protection of the Netherlands, the amount of emission of fluorine containing greenhouse effect gas (in CO2 conversion) reached 8-14% of all the amount of greenhouse effect gas emitted in 1990 unless the control is reinforced. An outline of the TEWI-3 project was introduced which is useful for comparing effects of substitution technologies on global warming. 14 refs., 11 figs., 29 tabs.

    This paper describes the considerations on the influence of the global warming on the environment, and the discussions on the measures against the climatic changes. With respect to the environmental effects by the global warming, the considerations were given based on the studies on the effects of mainly the Quaternary climatic changes on the surface sea water temperatures, sea level and animal flocks. If the magnitude of the climatic changes anticipated to occur during the 21st century is lower than that have taken place in the past 10,000 years during which the agricultural production has developed to a full-scale, there would be no fear of drastically changing the ecology on earth. If the estimation of future climatic and environmental changes becomes possible, then four basic positions could be selected for establishing the contermeasure plans. That is, the first is the measures to correspond to birth-rebirth transmigration; the second is the measures to carbon dioxide disposition upon concluding that the cause for the global warming is the atmospheric increase of carbon dioxide concentration, measures for conservation and international cooperation; the third is to deal with the warming environments; and the fourth is the means to reconstruct the earth. While a number of countermeasures may be prepared, Which of them should be selected will be decided by the amount of effects. 15 refs., 6 figs., 1 tab.

    It is a matter of course that the issue of the global warming requires management of policy science, but the ultimate target of various propositions is not just the holding back of the global warming which causes the collapse of living; it is necessary to check the propositions from the viewpoints of evasion of international strifes, security of fairness among generations, measures against uncertainty, and measures delayed from the actual phenomena. For Japan it is necessary to declare its responsibility to the environment, and make it clear that Japan pays sufficient costs and efforts. In order to exhibit its leadership, Japan must clarify its stance and then contribute to the world making the most of its unparalleled ability consolidated in the systematic and technical background of public pollution and in the cultural conception. Targeted policies will be the support of developing countries in their independent environmental management, exhibition of leadership in the environmental field and acceleration of international agreements. 4 refs., 1 fig.

    The recent situations of global warming mitigation measures related to flurine-containing greenhouse gases of HFC, PFC and SF{sub 6} are surveyed. In the meeting of the Parties of Montreal Protocol of 2000, no decision has been made on HCFC phaseout schedule amendment in the developed and developing countries, which is one of the major items. COP-6 has failed to reach agreement on handling CO2 absorption sources. For the international trends in estimation of the emissions of HFC and others, the IPCC's emission estimation methodology guidance for HFC, PFC and SF{sub 6} (translated into Japanese) and the methodologies taken by other countries are introduced. The trends of the emission control measures for HFC, PFC and SF{sub 6} include CO2 refrigerant application for mobile air-conditioners, announcement by Coca-Cola of HFC phaseout by 2004, announcement by the Canadian refrigerant air-conditioner industry of introduction of the surcharge system for promoting refrigerant recovery, and SF{sub 6} emission reduction technologies in Mg fabricating industries. Also introduced are cost evaluation of emission reduction technologies, latest scientific knowledge in the global environments, and harmonization of global warming mitigation and ozone layer protection in the developing countries, among others.

    This paper summarizes mainly on HFC, PFC and SF{sub 6} the trends in the last one year in technologies and regulations that can make compatible the ozone layer protection and the global warming prevention. Activities of the HFC/PHC task force established jointly by TEAP and IPCC are very important in deciding the future positions of HFC, PFC and SF{sub 6}. This paper reports the status of activities taken during fiscal 1999. IPCC reviewed the method of calculating the quantity of greenhouse effect gas emission. The paper introduces from its draft the gist of calculating the discharge quantity of HFC, PFC and SF{sub 6}. Introduction is given from the HFC/PFC task force report the actual status of using coolants, foaming agents and aerosols using HFC, PFC and SF{sub 6}, and the trends of developing substitution technologies. The paper introduces a fluorocarbon destruction technology as an international trend in discharge suppression measures. The paper reports movements of COP-5 in fiscal 1999 for gases other than the three gases including HFC. Chlorobromo-methane was indicated as a new substance, and n-propyl-bromide was decided to continue with measurement of ozone destruction coefficient. (NEDO)

    The trend survey was conducted of global warming protection measures by participation in international conferences, scientific society meetings and lecture meetings, and by literature surveys. We participated in the international conference on ozonosphere protection measures. In the 9th meeting of the nations which concluded the Montreal Protocol, the strengthening of restrictions on methyl bromide was decided on. In the UNEP solvent technology selection conference and the OORG conference of the World Bank, reports were made on substituting solvents in Japan, activities supporting developing countries, and the developmental trend of urethane use foaming agent. In the international conference on ozonosphere protection measures, introduced were the present status of Japan`s ODA for developing countries and examples of success of the substitution in the solvent field. The paper included nine reports on CFC destruction technology related literature made public in the past one year. The paper also introduced a comparative study of de-HCFC substituting technology at U.S. Oak Ridge National Laboratory, U.S. EPA`s prediction of emission of fluorine 3 gas, the predicted value of HFC emission and trial calculation of contributing rate in all greenhouse gases by IIR, Green Peace and Elf Atochem, and NOAA`s measured data on SF6 in the atmosphere. 49 refs., 46 figs., 26 tabs.

    Noda, A [Meteorological Research Institute, Tsukuba (Japan)

    1993-05-01

    This paper introduces models to predict global warming-up caused by greenhouse effect of the earth and increase in greenhouse effect gases, and the prediction results. As a result of CO2 doubling experiments using three-dimensional climate models in predicting the global warming-up, a model that predicted a sharp rise in annual average ground temperatures on the entire earth showed a larger increase in precipitation. According to the result of the CO2 doubling experiments using atmosphere-ocean coupling models, it was learned that the temperature rises higher in high latitude regions rather than rising uniformly over the earth on the whole. The fact that the temperature rise when CO2 has been doubled in a CO2 gradually increasing experiment is smaller than in the doubling experiment can be understood as a delaying effect of oceans generated from their thermal inertia. The former experiment showed a remarkable non-symmetry between the Southern and Northern hemispheres, reflecting the effect of the great oceanic circulation. Increase in cloud amount has an effect of either cooling or warming the earth, but the cooling effect surpasses the warming effect reportedly. Sulfuric acid aerosol in the troposphere is thought to influence the process of solar radiation transmitting through the atmosphere and have an effect to cool down the ground surface. 12 refs., 6 figs.

    A summary is described with respect to the relation of the global warming with coral reefs on the environmental estimation based on the sea level rise, and the development of counter-technologies utilizing the CO{sub 2} fixing capability of coral reefs. if no measures are taken to reduce discharge of greenhouse effective gases, the air temperature will rise by 1{degree}C by the year 2025, and 3{degree}C by 2100. The thermal expansion of sea water and partial melting of land ice caused from the said temperature rise will cause the annual sea level rising speed to climb to 6 mm in the next century. It is estimated that the sea level will be elevated higher by 25 cm by the year 2025, 65 cm by 2100, and the maximum of 1 m than the present level. The upward growth rate of reef ridges is between 1m and 4m in 1000 years, and the growth of reef rides as the frameworks of coral reefs and lime alga ridges can not catch up the sea level rise of 6 mm/year. This may cause a possibility of sea water erosion or inundation. As a possible contermeasure, an expectation is placed on structuring coral reef eco-factories which may be possible as a result of elucidating the CO{sub 2} fixing mechanism in coral reefs and utilizing the capability to its maximum. 23 refs., 7 figs., 1 tab.

    In this report, for Japan and typical developing countries and for the CO2 emitted from the combustion process of the fixed type exhaust source which is easy in recovery, technical problems and economical problems were made clear in case of using the recovered CO2 for the industrial field, and at the same time, effects of the energy conservation were studied. As to CO2, the two methods were considered: a method to use the recovered CO2 as it is and a method to use the carbon compound obtained by reducing CO2 by any method. Further, in the industrial field, there are a lot of industries which use CO2, carbon, methanol, etc., and in the present situation fossil fuel is used for production materials such as CO2, carbon and methanol. As substitutes for fossil fuels for the industries using these hydrocarbons as raw material, the use of the recovered CO2 and the synthesized hydrocarbon was considered. And, survey was made of the applicable industrial fields, the amount of the recovered CO2 use there, and effects of energy conservation by reduction in amount of the fossil fuel use. (NEDO)

    Two articles of 'Methods of saving the earth from warming' and 'We can be friends of the earth' are included in this report. The former gives a plain explanation of some points in these articles in consideration of global warming drawing general concern. The first is to reduce the amount of warming gases. For example, if the houses of Asahikawa Specifications are built in Tokyo, the energy required for air conditioning is reduced down to 1/3 - 1/7 of the one in ordinary houses. The second is to exhaust no warming gases by substituting natural energy sources for fossile fuels. The third is to fix CO2 and, in this respect, vegetable factories combined with bionics may be useful. The latter introduces dreams such as air conditioning utilizing solar energy, self-supporting houses, solar bicycles, and super energy-saving cars applied with various kinds of natural energy for the purpose of being used as energy harmless to the earth. Furthermore, it suggests the concepts of super energy-saving and wasteless equipment and systems in the title of E[sup 3] technology. 2 refs., 7 figs.

    The Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change (COP3) will be held in Kyoto in December 1997. Described herein are the current status and issues of the convention. USA and Japan, which hold important keys to set up the abatement target, have issued no proposals concretely at the current AGBM (Ad-hoc Group Berlin Mandate) 7, and the conference for the concrete targets will be decided in the next AGBM 8 to be held in October. The final target will be set by the ministerial segment of COP3, because the negotiations for the treaty are political in nature. USA proposes reduction at a uniform, realistic rate, and Japan proposes reduction at a uniform rate or setting up the emission target per capita, each being different from reduction at a much higher uniform rate proposed by EU. Within EU, however, 10% out of 15% reduction rate it proposes is agreed by the member countries, and the remaining rate of % may not be agreed. It is necessary for the advanced parties to set up realistic and legally binding solutions, including ratification by USA, which can persuade the developing countries. tab.1

    This paper describes the following matters on the problems of global warming and sea level rise. The first evaluation report published by the inter-government panel on climate change (IPCC) in 1990 estimates that, if emission of greenhouse effect gas keeps increasing at the present rate, the air temperature and the average sea level would rise by 3[degree]C and 65 centimeters, respectively by 2100. Global warming would not only result in rise of the sea level, but also accompany changes in strengths and routes of tropical low pressure areas, and precipitation patterns. Downstream areas of large rivers and island countries on coral reefs may have a risk of getting submerged. Countries having coasts developed to high densities (Japan, for example) would be subjected to a high potential effect. An 'East Hemisphere International Conference on Sea Level Rising Problem' was held in Japan in August 1993 as part of the works to prepare the second evaluation report of the IPCC (publication scheduled for 1995). The conference was attended by 24 countries, and 43 study results were reported. 4 figs.

    1993-05-01

    This Paper describes briefly a question of whether growing coral reefs could be an effective means to fix CO2 in sea water in order to mitigate global warming: Growing coral reefs could be a promising method from the following three views: Photosynthesis performed by diverse ecosystems that constitute coral reefs is thought to excel calcification (accompanying CO2 discharge from sea to the atmosphere); corals all over the world would fix CO2 at an annual rate of several hundred million tons; and no much energies are consumed to fix CO2. However, these favorable views depend upon another condition that a time period for the CO2 fixation is not too short (a measure for the time being is 100 years or longer). Elucidating where organic matters generated by the photosynthesis would go is an important question to meet this requirement. The paper indicates that measuring nitrogen and phosphor balances in addition to carbon balance is effective for measuring ratio of a net photosynthesis rate to the calcification rate. 4 refs., 1 fig., 4 tabs.

    Networking is being executed with an objective of exchanging information on global environment technologies at an international level. In order to further promote the information exchange, and to make web sites user-friendly, fiscal 1998 has performed structuring a thesis renewal system. As a result of structuring the thesis renewal system, researchers can use the system as using a word processor by inputting data from a terminal in their laboratories. The data can also be made into a data base nearly semi-automatically. In addition to reducing time loss, delay and input errors because of re-entry, the researchers can make the data into a database on nearly a real time basis, and can provide their own theses to any part of the world through Internet. With regard to retaining Internet security, the security software having been introduced last year was renewed. In addition, detailed status such as daily access has become possible of identification as a result of introducing the net intellect. (NEDO)

    This paper reports the research results on the present state and future trend of protective measures for the ozone layer, and the trend of preventive measures against global warming by substituting CFCs such as HFC, through international conferences, meetings and lecture meetings, and literature survey. In the 8th meeting of the parties to the Montreal Protocol, it was presented that refrigerator producers in Thailand phased out CFCs from their products earlier than the schedule in cooperation with Japan. The final draft including the approval of essential use from 1997 to 2002 was reviewed, and reported to the technology/economy assessment panel. Reduction of ozone depleting substances was guided in Thailand, Indonesia and Philippines. The latest trend of substituting technologies of HCFC was surveyed, and the control trend of F-containing greenhouse effect gas emission was also surveyed through the conference of the parties of climate change in fiscal 1996. Based on the IPCC report in 1995, the emission amount of greenhouse gases of nearly 10% in contribution such as CO2, methane and fluorocarbon was arranged. R and D on destruction of CFCs was also surveyed. 35 refs., 54 figs., 32 tabs.

    2005-12-01

    The CDEX (Center for Deep Earth Exploration, JAMSTEC) is an implementing organization of a riser drilling vessel, CHIKYU ("Earth"). CHIKYU has a large capability to produce a wide variety of data, core measurement data, logging data, mud logging data, cuttings data and monitoring data in boreholes, etc. Also CDEX conducts site survey for safety drilling and publication before and after cruises. It is critical that these diverse data be managed using a unified, coherent method, and that they be organized and provided to users in an intuitive, clearly understandable way that reflects the aims and underlying philosophies of the IODP and JAMSTEC. It is crucial that these data are accessible to users through an integrated interface in which all data formats, management tools, and procedures are standardized. Meeting these goals will assure total usability for scientists, administrators, and the public, from data creation to uploading and cataloging, to end use and publication. CDEX is developing an integrated information management system, call "SIO7" (Scientific Information from 7 Oceans) for CHIKYU operation, and would like to extend to adopt various information handling systems in geosciences. The SIO7 composed of 2 major systems, J-CORES (JAMSTEC Core Systematics) and DEXIS (Deep Earth Exploration Information System) (see http://sio7.jamstec.go.jp/ for the details). J-CORES is a database system designated to manage all aspects of core data. The system is modeled on the JANUS system developed by and for ODP, but implements an extended, somewhat modified data model. The functions that support onboard and real time data input operations have also been strengthened. A variety of data visualization and visual core description functions have been added, and data loading from those applications has been automated, making the system as a whole both powerful and easy to use. On the other hand, DEXIS is developed based on the combination and integration of existing off

    The present paper suggests chief measures to suppress and reduce global greenhouse gases. Under the control of artificial environments such as bioreactor, hydroponics and vegetable factory, a very high fixing rate of CO2 can be obtained, but CO2 generation accompanying electric power consumption is also large. It is preferable to use methane as resource by reforming reactions or selective oxidative reaction. In the recovery technique of fluorocarbon, 100% recovery is desirable. Techniques for decomposing recovered fluorocarbon and converting it to harmless material are the most backward ones. Understanding of essential structural relationship of coal is necessary for establishing combustion technique for the reduction of N2O. The integrated power generation system composed from solid electrolyte type fuel cell and coal-gasifying process, high-performance, superheat pump system form scientific technology imposing no burden on the global environment. Establishment of purification technique for industrial- or living-related drain inflowing to a closed water area system, establishment and reinforcement of inspection system for oil spill in the oceans in a global scale are required. 240 refs., 63 figs., 30 tabs.

    This report dealt with the background of energy policies in E.U. countries and energy plans. At COP3, E.U. countries internationally gave a pledge that they will reduce the emission of greenhouse effect gas 8% from that as of 1990 during 2008-2012, which is stricter than those given by Japan and the U.S. Actually, the European Commission made public 'Toward the European Climate Change Programme' and 'Green Paper on Emissions Trading in the E.U.' These are correspondent to E.U.' global warming preventive strategy which is called the twin track approach by the European Commission.

    This report dealt with the background of energy policies in E.U. countries and energy plans. At COP3, E.U. countries internationally gave a pledge that they will reduce the emission of greenhouse effect gas 8% from that as of 1990 during 2008-2012, which is stricter than those given by Japan and the U.S. Actually, the European Commission made public 'Toward the European Climate Change Programme' and 'Green Paper on Emissions Trading in the E.U.' These are correspondent to E.U.' global warming preventive strategy which is called the twin track approach by the European Commission. The former is a frame for coordinating individual reduction measures taken under the responsibility of member countries as the whole E.U.

    The results of the overseas survey were summed up mostly of global warming prevention measures taken by the U.S. government and those by private companies. At COP3 in 1997, the U.S. gave a pledge internationally that they would reduce greenhouse effect gas emissions during 2008-2012 7% below from that in 1990. But the U.S. government seems hesitating to take concrete measures in regions. Hesitating, however, they are publicly making it a target to find how to eliminate a risk of global warming which is now a global problem in cooperation with other countries and international organizations. Concretely, programs are as follows: ranking of the energy consumption amount of household electric appliances, housing loan programs taking energy efficiency into account, preferential taxing system, incentive money system in case of using the substituting energy transportation program, waste management program, commendation of men of achievements and prize-winning, etc. (NEDO)

    Efforts are exerted to develop new technologies whereby carbon dioxide is absorbed by and fixed in rapidly growing trees. The trees are felled and subjected to high-efficiency carbonization, and the thus-obtained carbonized material is used for environmental purification or the like and then buried in the ground. Studies are under way to find out if the cycle (operations) may be organized into an industry. Activities are conducted in the five fields of (1) carbonized materials, (2) carbonization, (3), industrial use of charcoal, (4) stabilization of charcoal, and (5) reports on surveys (mainly overseas). In field (2), following an introduction consisting of the carbonization mechanism and the definition of terms, surveys are conducted of the existence of carbonizable resources in Japan, distribution channels of imported charcoal and activated charcoal in Japan, various carbonization apparatuses, carbonization equipment incorporated into gasifying fusion furnaces, carbonization furnace as a system, and the trends of development of pyroligneous acid and development of its use. In field (3), studies are made on its use in industries, on its application to agriculture, forestry, and livestock industry, and on the utilization of its electromagnetic properties. (NEDO)

    The dye finishing operation in the textile industry places heavy load on the global environment. This paper describes the achievements in fiscal 1998 on development of process to eliminate the load. Low-temperature plasma treatment was introduced into the desizing and refining process to develop a continuous treatment process using no water and chemicals. Quality equivalent to that produced by conventional methods was obtained by applying an appropriate plasma treatment condition. The energy saving rate was presented by reduction by 84.3% converted into steam. Conventional dye finishing operation uses three to six times as much water as the cloth weight. The developed air flow treatment device reduced the water ratio to less than one. This is 86.0% reduction of energy consumption converted to steam. In removing pectic substance in cotton refining, no water, chemicals and steam were used, but were substituted by enzyme for continuous treatment. Good finishing result was obtained by performing bleaching and dying. Enzyme cost is an issue, but the cost would decrease if it is used in large quantity. A two-dimensional colorimeter (measures cloth color with high clarity and reproducibility) and an automatic dye preparing device (with high volume measuring performance) were developed. If the cost required for re-coloring under the present inspection method is converted into energy, it corresponds to 81.6% reduction. (NEDO)

    Investigations in relation with the greenhouse effect gas emission trading system have been performed on introduction and discussion of the system in major countries in order to discuss basically the emission trading system in Japan. The EU has been advancing the discussion with the introduction thereof to start in 2005 kept in mind, whereas the points of issue for the system designing include the followings: what roles should be taken by the EU and membership countries, consistency between the membership countries with regard to the participating organizations, and the scheme for initial allocation. In Denmark, the emission trading system has been introduced in January 2001 between the electric power companies. The objects of the allocation are only the eight power generation companies, making the management of emission right retaining quantities by the government simple. The United Kingdom has a schedule of introducing the emission trading system in April 2001, but the trading itself will start in 2002. Management of the trading scheme, and acceptability of banking after 2008 are the main points of issue. In the fundamental discussions on designing the emission trading system in Japan, discussion items were extracted, and the points of issue were put into order. (NEDO)

    HFC-23 is produced as a by-product during HCFC-22 manufacturing (produced at by-production rate of about 2%, whereas the reaction control has limitation in reducing the production). This is one of the substances subjected to the greenhouse effect gas reduction in the climate change framework treaty. This paper describes the achievements in 1998 on developing the HFC-23 destruction technology. High-temperature pyrolysis decomposes the substance into HF and CO2, which are given absorption treatment by water and alkali to make them harmless, and are recovered finally as calcium fluoride. An equipment having the treatment capability of 195 kg/h was constructed. Design was made on a facility capable of treating fluorine containing waste water at 3 t/h at maximum. Utilities consumed in a factory (industrial water, acids for neutralization, and alkali) are used effectively to identify the effect of reducing the treatment cost. Discussions were given from the safety aspect on facilities to prevent leakage of fluorine containing waste water being a harmful substance. Fabrication was executed on a full-size treatment testing equipment that can utilize the utilities in the factory effectively, and trial equipment operation was performed to arrange the system prepared toward the future tests and researches.

    This paper summarizes the basic materials related to unified evaluation models for global warming. The unified evaluation is a disciplinary process to combine, interpret and share the information from different scientific disciplinary areas in such a form that the whole cause and effect chain can be evaluated from a macroscopic view. The process has higher utilization value than the evaluation overemphasizing a single academic area, and can provide decision makers with useful information. The process is suitable to model complex interactions and feedback mechanisms in diversified scenes such as climate change. The unified evaluation can identify the policy criteria along with a measure framework having consistency. The evaluation process is repetitive and continuous, wherein a science community can convey comprehensive knowledge and finding to a decision making community. In turn, the decision making side can feed back the experiences and achievements in learning. Execution of the evaluation requires different approaches, such as judgement of specialists including the modeling methods and experience, discovery as a result of applying the policies, and survey methods. The paper also describes the gaming conception, scenario analysis, and unification evaluation methods. (NEDO)

    The present semiconductor manufacturing process uses a great amount of PFC having large global warming coefficients and extremely long atmospheric life. A research was made particularly on reduction of its emission from etching processes. After introducing how the semiconductor industry has been working conventionally on protection of the global environment, this paper makes clear the purpose and positioning of this preceding research, as well as how it is moved forward. The paper also reports the results of analyzing and discussing the exhaust gases from etching devices using several kinds of substitute PFC gases. Survey results are reported on the possibilities of new substitute gases, plasma decomposition and treatment of exhaust gases, reaction process simulation, and in-situ analyzing and evaluating technologies. Investigations were made on the possibility of using no PFC in wiring processes which consume greater amount of PFC, as well as on wiring techniques using inter-layer insulation film with low dielectric rate, a new wiring structure forming technology, new functional elements, circuits and systems in a wide range. Proposals were given on specific research and development themes and plans that begin in fiscal 1999. (NEDO)

    We obtained X-ray computed tomography (X-ray CT) images for all cores (GT1A, GT2A, GT3A and BT1A) in Oman Drilling Project Phase 1 (OmanDP cores), since X-ray CT scanning is a routine measurement of the IODP measurement plan onboard Chikyu, which enables the non-destructive observation of the internal structure of core samples. X-ray CT images provide information about chemical compositions and densities of the cores and is useful for assessing sample locations and the quality of the whole-round samples. The X-ray CT scanner (Discovery CT 750HD, GE Medical Systems) on Chikyu scans and reconstructs the image of a 1.4 m section in 10 minutes and produces a series of scan images, each 0.625 mm thick. The X-ray tube (as an X-ray source) and the X-ray detector are installed inside of the gantry at an opposing position to each other. The core sample is scanned in the gantry with the scanning rate of 20 mm/sec. The distribution of attenuation values mapped to an individual slice comprises the raw data that are used for subsequent image processing. Successive two-dimensional (2-D) slices of 512 x 512 pixels yield a representation of attenuation values in three-dimensional (3-D) voxels of 512 x 512 by 1600 in length. Data generated for each core consist of core-axis-normal planes (XY planes) of X-ray attenuation values with dimensions of 512 × 512 pixels in 9 cm × 9 cm cross-section, meaning at the dimensions of a core section, the resolution is 0.176 mm/pixel. X-ray intensity varies as a function of X-ray path length and the linear attenuation coefficient (LAC) of the target material is a function of the chemical composition and density of the target material. The basic measure of attenuation, or radiodensity, is the CT number given in Hounsfield units (HU). CT numbers of air and water are -1000 and 0, respectively. Our preliminary results show that CT numbers of OmanDP cores are well correlated to gamma ray attenuation density (GRA density) as a function of chemical

    The status of the methane generation due to landfill with waste has been analyzed to investigate the actual circumstances of effective utilization of methane in the world and its possibility. The artificial generation of methane is 375 Tg per year among the total methane generation in the world, 535 Tg per year. The methane generation from the landfill with waste is 40 Tg per year, which becomes a rather large contribution. The methane generation from the landfill with waste in Japan is estimated to be from 130 to 520 Gg per year, which is a rather low value as a share in the world. This is caused by the sub-aerobic property of landfill in Japan, and the methane generation can be suppressed. Accordingly, there are no systems using recovered methane as energy source in Japan. In the USA, profitability of energy recovery can be established in 600 to 700 landfills among about 6,000 landfills. The methane recovery is practically conducted at more than 120 landfills. The recovered methane is used as a power generation fuel. 45 refs., 43 figs., 27 tabs.

    With relation to some global energy systems of which viability is predicted in the future, an evaluation was conducted from the viewpoints of economical efficiency, energy balance, CO2 emission, etc. The fossil fuel CO2 capture system, the conventional thermal power plant added with CO2 recovery/treatment facilities, is expected to reduce approximately 70-75% of the CO2 emission. The fossil fuel decarbonated hydrogen system, which decarbonates fossil fuels, recovers/treats CO2 at the place of fuel supply and uses as hydrogen, is of poor practical application from an economical point of view. The fossil fuel methanol synthesis system, which synthesizes methanol from fossil fuels at the place of fuel supply, generates electric power and recovers/treats CO2 with the methanol, is large in energy loss and CO2 emission and low in overall efficiency and CO2 reduction effect at the time of methanol synthesis. The renewable energy hydrogen system is an ultimate system with no emission of CO2, though it costs much. 110 refs., 83 figs., 107 tabs.

    Listvenite, quartz-carbonate altered ultramafic rock containing minor fuchsite (Cr-muscovite) forms by complete carbonation of peridotite and is thus an attractive objective for carbon mitigation studies. However, reaction controls and evolution of listvenite are still enigmatic. Here we present the first results of Phase 1 of the ICDP (International Continental Drilling Program) Oman Drilling Project and subsequent core logging using the analytical facilities on board the research vessel D/V CHIKYU. Hole BT1B contains 300 m of continuous drill core intersecting alluvium, listvenite-altered serpentinite, serpentinite, ophicarbonate and the underlying metamorphic sole of the Semail ophiolite, Oman. The drill core has been systematically investigated by visual core description, thin section petrography, X-ray fluorescence core logging, X-ray diffractometry, visible-shortwave infrared imaging spectroscopy and X-ray Computer Tomography. Our observations show that listvenite is highly variable in texture and color on the mm to m scale. Listvenite was visually categorized into 5 principal color groups: the dominant dark red (47 %), light red (19 %), orange (14 %), pale (2 %) and green (16 %). The presence of hematite/goethite results in dark reddish, red and orange hues. Light grey or pale colored listvenite lacks hematite and/or goethite veins and may represent the `true' listvenite. Green listvenite is characterized by the presence of cm-sized quartz-fuchsite intergrowths. Five zones of serpentinite, which vary in thickness between several tens of cm and 4 m, are intercalated within the massive listvenite of Hole BT1B. Gradational listvenite-serpentinite transition zones contain the ophicarbonate assemblage (magnesite + serpentine) and sometimes additional talc, representing intermediate carbonation reaction progress. Preservation of the former mesh texture and bastite after orthopyroxene in the listvenite suggest that the listvenite precursor had already been

    As to the development and introduction of the global warming mitigation technology, the paper studied an approach to the formation of a social consensus and how to apply concrete methods and proposed a realistic approach in the light of the present situation of public enterprises in Japan. As tools and rules which are particularly important in activities of forming the consensus, the paper cited up what the PR control should be, responses to mass communications, HP making and regulation/preparation of the related laws, and made a concrete study. As examples in which there occurred friction with the society due to the insufficient formation of consensus, the following construction plans were taken up to consider problems, etc. in disclosure of the information in the plans: Underground Research Laboratory, movable weir in the Yoshino River, and waste disposal facilities at Fuimae tideland. Also in Japan, some methods for the consensus formation have been carried out, and in the survey, as concepts for classifying the methods, two different approaches, Public Outreach and Public Relations, were introduced. As to the former, a consensus formation method in the construction of power plants in Japan was introduced, and as to the latter, a method in consensus conferences in the U.K. (NEDO)

    The United Nations Framework Convention on Climate Change is studied from the viewpoint of implementing costs. As far as the global warming issue is concerned, the factor to affect the environment is not the emitted volume but the concentration in the air. The ultimate target is the stabilization of greenhouse gas concentration at a level not to impose serious artificial damage on the ecosystem. Accordingly, various time paths are considered, including one in which much emission is allowed at the beginning and suppression is enforced acceleratedly in the later stage. In this study, a path demanding but the minimal cost in the period up to the target time point is discussed, using as the tool the marginal cost for measure implementation. In a reasonable emission control strategy, the emission control marginal cost follows a time path that is dependent upon an increase function to be determined by the discount rate and survival rate (time constant) in the atmosphere. In the industrial branch, instead of imposing short-term and rigid emission volume control limits, a longer-term target may be set for reduction in the loads responsible for concentration acceleration, concrete emission controls under the given conditions may be implemented at the discretion of the implementing organizations, and reduction in cost may be realized by time distribution with the environmental impacts kept at approximately equal levels. 5 refs., 2 figs., 3 tabs.

    The JEOL JSX-3600CA1 energy dispersive X-ray fluorescence core logger (XRF-CL) on the D/V Chikyu provides quantitative element concentrations of scanned cores. Scans of selected intervals are made on an x-y grid with point spacing of 5 mm. Element concentrations for Si, Al, Ti, Ca, Mg, Mn, Fe, Na, K, Cr, Ni, S and Zn are collected for each point on the grid. Accuracy of element concentrations provided by the instrument software is improved by applying empirical correction algorithms. Element concentrations were collected for 9,289 points from twenty-seven core intervals in Hole BT1B (basal thrust) and for 6,389 points from forty core intervals in Hole GT3A (sheeted dike-gabbro transition) of the Oman Drilling Project on the D/V Chikyu XRF-CL during Leg 2 of the Oman Drilling Project in August-September, 2017. The geochemical data are used for evaluating downhole compositional details associated with lithological changes, unit contacts and mineralogical variations and are particularly informative when plotted as concentration contour maps or downhole concentration diagrams. On Leg 2 additional core scans were made with X-ray Computed Tomography (X-ray CT) and infrared images from the visible-shortwave infrared imaging spectroscopy (IR) systems on board. XRF-CL, X-ray CT and IR imaging plots used together provide detailed information on rock compositions, textures and mineralogy that assist naked eye visual observations. Examples of some uses of XRF-CL geochemical maps and downhole data are shown. XRF-CL and IR scans of listvenite clearly show zones of magnesite, dolomite and the Cr-rich mica, fuchsite that are subdued in visual observation, and these scans can be used to calculate variations in proportions of these minerals in Hole BT1B cores. In Hole GT3A XRF-CL data can be used to distinguish compositional changes in different generations of sheeted dikes and gabbros and when combined with visual observations of intrusive relationships the detailed geochemical

    An energy supply system which is globally formed for global environmental protection is called a global energy system (GES), in which to achieve substantial CO2 reduction, various measures against CO2 are introduced to energy systems extending from places of fuel supply to places of fuel consumption. For the study of a scenario for introduction such a GES, it is necessary to investigate the GES presently proposed and make a traverse evaluation of it under uniform preconditions and evaluation criteria. Concretely, following a case study of evaluating performance of the GES with a power system as the final form from viewpoints of economy, energy balance, CO2 emissions, etc., the paper arranged characteristics of liquid fuel supply systems including methanol from a traverse aspect, made evaluation of performance and possibilities of the introduction in the areas concretely named, and studied positioning of this energy system, scenario for the future introduction and possibilities of the introduction from global and long-term aspects. 79 refs., 102 figs., 77 tabs.

    Full Text Available During the Integrated Ocean Drilling Program (IODP Expedition 331 at the Iheya North hydrothermal system in the Mid-Okinawa Trough by the D/V Chikyu, we conducted microbiological contamination tests of the drilling and coring operations. The contamination from the drilling mud fluids was assessed using both perfluorocarbon tracers (PFT and fluorescent microsphere beads. PFT infiltration was detected from the periphery of almost all whole round cores. By contrast, fluorescent microspheres were not detected in hydrothermally active core samples, possibly due to thermal decomposition of the microspheres under high-temperature conditions. Microbial contamination from drilling mud fluids to the core interior subsamples was further characterized by molecular-based evaluation. The microbial 16S rRNA gene phylotype compositions in the drilling mud fluids were mainly composed of sequences of Beta- and Gammaproteobacteria, and Bacteroidetes and not archaeal sequences. The phylotypes that displayed more than 97% similarity to the sequences obtained from the drilling mud fluids were defined as possible contaminants in this study and were detected as minor components of the bacterial phylotype compositions in 13 of 37 core samples. The degree of microbiological contamination was consistent with that determined by the PFT and/or microsphere assessments. This study suggests a constructive approach for evaluation and eliminating microbial contamination during riser-less drilling and coring operations by the D/V Chikyu.

    In order to provide discussion materials for measures to achieve the GHG emission reduction target, investigations and discussions have been made on the following subjects: cost effectiveness of reducing GHG emission by target countries and target technologies, use of maps and databases on the possible reduction quantity of GHG emission, the targeted countries and business categories. Regarding the target countries, investigations were made on the general situation of the energy consumption efficiency, difference between their energy consumption efficiency by industries and that in Japan, and the GHG emission quantities by sectors. As a result, 31 counties hopeful in reducing CO2 emission were selected. With regard to technologies to reduce CO2 emission, technologies having been practically used and proliferated in Japan were used as the base, whereas 43 technologies were systematized for such departments as industries, business operations, households, and transportation. According to a trial calculation on the effect of CO2 emission reduction, if the 43 technologies are applied to the 31 target countries, CO2 emission reduction of 698 million tons as a whole would be possible, for which the required expense was calculated as 114.4 trillion yen. In evaluating the CO2 emission reducing technologies, the cost effectiveness of each technology was evaluated by cost per GHG emission reduction of 1t-CO2. (NEDO)

    The present investigative research is intended to grasp the whole image of cost effectiveness of the energy saving and new energy technologies to suppress and reduce CO2 emission in Japan. Furthermore, the research considers the cost effectiveness and discusses the efficiency and the directionality of reducing CO2 emission from an estimation of the social introduction cost of individual technologies and quantity of CO2 emission reduction. These activities are intended to provide the fundamental items of information when discussing the measures to achieve the emission reduction target imposed on Japan. The research divides the whole aspect into energy conversion, industrial, consumer and transportation departments for discussion, and calculates the technological items that can be introduced by 2010 and the quantity of the introduction thereof, as well as the effect of reducing CO2 emission. Calculations are also performed on 27 elementary technologies in total and the CO2 emission reducing effect, assuming technological possibilities. Subsequently, analyses are carried out from the viewpoint of cost effectiveness by departments. It is shown that the average cost effectiveness is distributed in the range from 108,000 yen/ton to 1,129,000 yen/ton. Scenarios of reducing CO2 emission are discussed from the analyses of the cost effectiveness. (NEDO)

    This paper takes general view of the history of global environmental problems. A UN human environment conference was held in Stockholm in 1972, at which the human environment declaration and an action plan were adopted. The most important among the results of the Stockholm Conference were the treaty on international transactions of wild animal and plant species feared of extinction in the 1970's, the international treaty on prevention of pollution caused by ocean vessels, and the treaty on prevention of ocean pollution caused by dumping of wastes and other materials. Also adopted in the 1970's include the action plan to prevent desertification, the action plan on the world population, and the world weather plan. The UN Nairobi Conference in 1982 has sounded the alarm on the delay in tackling with the facing problems and the progress of aggravation in the global environment. In 1987, the ozone layer protection protocol was adopted. The earth summit at Rio de Janeiro in 1992 adopted the Agenda 21, with which the participating nations, autonomous bodies, and civil organizations have prepared their own Agenda 21, and are now about to begin challenging the global environmental problems. 7 refs., 4 tabs.

    Developments are made on an optical imager (ASTER) used to collect mainly images of land areas and an infrared sounder (IMG) to measure vertical air temperature distribution and vertical concentration distribution of specific gases, as satellite mounted sensors for earth observation. All the sensor characteristics of the ASTER comprising a visible near infrared radiometer, short wave infrared radiometer and thermal infrared radiometer are required to be capable of providing measurement, evaluation and assurance at the required accuracies during the entire life time. A problem to be solved is how to combine the on-ground calibration prior to launching, on-satellite calibration, and calibration between the test site and the sensors. The IMG is a Fourier transform spectroscopic infrared sounder, which is demanded of a high wave resolution over extended periods of time as well as a high radiation measuring capability. Also required are the level elevation of analysis algorithms to solve inverse problems from the observed radiation spectra, and the data base with high accuracy. 19 refs., 4 figs., 4 tabs.

    Measures against Cryptosporidium parvum (C. parvum) in the waterworks are discussed. C. parvum is a pathogenic protozoan, and exists in the form of oocyst protected by a hard shell. It does not multiply in water or food, but does in human intestines and causes violent diarrhea and bellyache. A grave concern was created when many people were infected with the protozoan via tap water in Japan and the United States. Under such circumstances, ozone is used in an experiment to inactivate C. parvum. It is found that the C. parvum oocyst inactivation effect is evaluated by using a Ct value (disinfectant concentration Cmg/Ltimescontact time in minute) and that ozone treatment inactivates 90-99% of the protozoan. When various advanced water treatment technologies are being introduced for the purpose of serving safe and tasty water, the outcome of this study conveniently offers an ozone treatment method that will additionally inactivate pathogenic protozoa. Studies will be continued to elucidate the effects of factors of ozone treatment and water quality for the completion of an ideal disinfection process. Reference is made to an example of disinfection work implemented at a water purification plant of Milwaukie City, United States. 9 refs., 6 figs., 4 tabs.

    This paper reports features of a wafer washing technology, a new IC wafer washing process, its pure water saving effect, and a `QC washing` which has pure water saving effect in the wafer washing. Wafer washing processes generally include the SC1 process (using ammonia + hydrogen peroxide aqueous solution) purposed for removing contamination due to ultrafine particles, the SC2 process (using hydrochloric acid + hydrogen peroxide aqueous solution) purposed for removing contamination due to heavy metals, the piranha washing process (using hot sulfuric acid + hydrogen peroxide aqueous solution) purposed for removing contamination due to organic matters, and the DHF (using dilute hydrofluoric acid) purposed for removing natural oxide films. Natural oxide films are now remained as surface protection films, by which surface contamination has been reduced remarkably. A high-temperature washing chemical circulating and filtering technology developed in Japan has brought about a reform in wafer washing processes having been used previously. Spin washing is used as a water saving measure, in which washing chemicals or pure water are sprayed onto one each of wafers which is spin-rotated, allowing washing and rinsing to be made with small amount of washing chemicals and pure water. The QC washing is a method to replace tank interior with pure was as quick as possible in order to increase the rinsing effect. 7 refs., 5 figs.

    This paper describes the progress and the major results of research and development on technologies and measures to prevent water pollution in China. Tests and researches have been performed on an upward anaerobic sludge blanket (UASB), a vertical baffled anaerobic sludge blanket, two-phase anaerobic digestion, and an anaerobic fluidized bed. When anaerobically digested sludge and aerobic active sludge are inoculated in the UASB, particle-shaped sludge was formed well in both sludges. This technology has begun to be used in breweries and citric acid factories. With anaerobic treatment of waste water containing sulfate, the sulfate was recovered as sulfur by using the first and second phases. Research and development is being progressed on the oxidation ditch technology as an improved version of the active sludge method. In a pilot test of a soil treatment system and a stabilization pond treatment system as alternative technology for the active sludge method, the BOD in the treated water was found 2.5 mg{times}1/l. Attentions are drawn on primary treatment, a living organism contact oxidation method, and a continuous filtration treatment process as technologies to turn polluted water into resources. 6 refs., 1 tab.

    This paper describes the survey of energy load leveling systems in Europe. In Denmark, especially regional heating is remarkably diffused, and they have 350 plants. With extending the service areas, the energy load leveling has been promoted. For the cogeneration plants of SK Power, the largest electric power company, they have hot water heat storage tanks for regional heat supply with a total capacity 2,200 MWh. The regional heating system in Goeteborg City of Sweden supplies 80% of the total heat demand of the city. Unused energy sources derived from petroleum refining, sewage treatment, and garbage burning are utilized. In Uppsala, they have seasonal heat storage systems using solar heat. The Vienna Regional Heat Supply Corporation supplies heat equivalent to 5,000 GWh a year. Cogeneration plants and garbage burning plants are used as heat sources, and 25% of the total heating in the city is supplied. In Austria, they have an electric power demand with a peak in winter, and they have a pumped-storage power station in Kaprun for the annual load leveling using dump power in summer. This paper also introduces a compressed air storage gas turbine plant at Huntorf of Germany, and a large-scale underground natural gas storage of Gaz de France. 6 figs.

    Some recent information is presented about the adhesion of organisms to marine structures. A biocoating is a community of microorganisms adhering to the surface of an object, composed of a matrix of exocrines and what it carries, which are suspended matters originating in the seawater and organic particles originating in the organisms. As a biotechnological measure for preventing the adhesion of large organisms, there is the use of synthetic repellents. New chemicals, however, have to clear the law requesting a review and approval of the authorities concerned before they can be put to use. Furthermore, their cost if high will give rise to another difficult problem. There are two chemical methods against them, one the injection of chemicals aiming at all larvae on the adherence stage and the other the execution of electrolysis for the formation of repellent chemicals in the seawater. In case a thick chemical concentration is mandatory for a good result, chemicals may be allowed to melt out of the coating or surface electrolysis may be caused by use of a conductive coating. Available for providing the object with an organism-rejecting surface are functional materials such as silicone, chlorine generating electrodes, and repellent-containing carriers. Also mentioned in this report are electrochemical methods, use of copper alloys or zinc, and application of silicone-based coatings. 129 refs., 16 figs, 8 tabs.

    This paper summarizes study trends mainly in CO2 fixing processes. Underground CO2 storage is a most promising method because it can fix a huge amount of CO2 and has low effects on ecological systems. Storing CO2 in ocean includes such methods as storing it in deep oceans; storing it in deep ocean beds; dissolving it into sea water; neutralizing it with calcium carbonates; and precipitating it as dry ice. Japan, disposing CO2 in these ways, may create international problems. Separation of CO2 may use a chemical absorption process as a superior method. Other processes discussed include a physical adsorption method and a membrane separation method. A useful method for CO2 fixation using marine organisms is fixation using coral reefs. This process will require an overall study including circulation of phosphorus and nitrogen. Marine organisms may include planktons and algae. CO2 fixation using land plants may be able to fix one trillion and 8 hundred billion tons of CO2 as converted to carbon. This process would require forest protection, prevention of desertification, and tree planting. Discussions are being given also on improving power generation cycles, recovering CO2 from automotive exhausts, and backfilling carbons into ground by means of photosynthesis. 23 refs., 7 figs., 1 tab.

    Two articles of 'Care of coppice in Wood Totoro' and 'Global environment protection from the universe' are included in this report. The former explains the necessity of coppice conservation through an example of Sayama Hill in Tokyo. Until the time 30 years ago, coppices are deeply related to people as the places which supply fuel and fertilizer to villagers, but they have been left or cut down by energy source conversion and development of home lots. Now we must learn the traditional methods of caring coppices again and find a new sense of values regarding the nature. The latter introduces satellite-used remote sensing which allows to continuously scan all the areas of the earth within a short period for global environment protection. This sensor uses a wide range of wavelengths from light to radiowave. In the U.S., it is operated in the name of LANDSAT since 1972, and Japan is also operating various kinds of satellites for environment research concerning, e.g., CO2 concentration and resource exploration. 10 figs.

    On the significance of UNCED, the background, the results of the conference and the reflection to the construction administration were described. The causes of global environmental problems such as the global warming, the ozone layer destruction and the decrease of forests can mainly be classified into 3. These are the problem of socio-economic activities of advanced countries such as mass production, mass consumption and mass dumping, the problem originating from the poverty in developing countries and the problem originating from the interests between advanced countries and developing countries. The main results in the UNCED were as follows: the signature to the two conventions as to the climate change and the biological diversity, the statement as to the principle for forests, the Rio Declaration which should be said to be the world constitution concerning the environment and development, and the adoption of the Agenda 21 of the draft which summarized the policies and measures. The Agenda 21 includes the fund, the technology transfer and the organization problems. In order to reflect these problems to the construction administration, it is necessary to promote the energy policy, the establishment of efficient traffic system, the effective land utilization, the appropriate management of river spaces, the urban policy and the recycling of resources.

    Forests have become drawing attention as an absorption source of carbon dioxide, a greenhouse effect gas. This paper discusses significance of forests from viewpoints of their roles as diverse ecological systems and socio-economic values. Forest is a place for living and resting of all kinds of living organisms including plants, animals and microorganisms. Living forms in forests being affluent in kinds and large in amount bring great favor to human societies. Forests play diversified roles other than biological roles in addition to largely affecting heat distribution on the ground through evapotranspiration. These roles include suppression of erosion on ground surface, alleviation of micro climate by reducing wind velocity on the ground, and disaster prevention. Forests have an aspect of supply source of production resources for societies as well as an aspect of unused lands. Efficiency of converting solar energy by plants looks inferior to that of solar cells. Biomass may be regarded as regenerative energy limited to a case where excess production is utilized. 142 refs., 56 figs., 44 tabs.

    Since the electric industry has grappled with a prevention of the environmental pollution such as the air pollution and water contamination as a forerunner in case of construction and operation of the power facilities, and at the same time has conducted actively the environmental conservation countermeasures, it has consequently achieved the environmental conservation level as a top level in the world. On the other hand, as for the emission quantity of CO2 relating to the earth warming, the power field occupies about one fourth of total Japan. Therefore the electric industry should aim at the electric energy supply considering the influence on the environment, such as the power supply structure to restrain CO2 emission as less as possible, higher efficiency of equipments, higher efficiency of energy utilization by using the unused energy and so forth. In addition to it, the consumer side should aim at the social structure with a recycle type such as saving resources and saving energy, and aim at changeover of life style. It is hoped to conduct the overall measure including the items mentioned above. In this report, the recent trend of earth enviromental problems, grappling with the environmental problems as a forerunner such as the prevention measure of air pollution in the thermal power plant, etc., and the correspondence to the earth warming problems are outlined. 11 refs., 9 figs., 3 tabs.

    This paper describes the removal technique of gases such as CO2, SO2 and NOx which have the deep relation to the maintenance of global environment. This paper describes partially r SO2 and NOx which are the primary cause of acid rain. As for the removal of CO2 generated from fixed sources (thermal power stations and others), the separation technique and isolation-fixation technique have been researched on and developed. Of the separation method, the effect of the chemical absorption method and the adsorption method is proved with the preceding experiments. The isolation method is differently researched on as to store under deep sea or ground but may be urgent and temporary. The fixation of CO2 is a serious global problem which relates to the afforestation and forests. The fixation which uses coral reefs in ocean as the absorption source has a potential. As for the processing of substances causing acid rain, the desulfurization from petroleum and the flue gas desulfurization have the excellent results. The improvement of combustion method or the flue gas denitrification at the fixed sources are used to remove NOx. The removal of NOx from all diesel cars is difficult compared with the exhaust gas cleaning of gasoline cars and is not commercialized. 11 refs., 1 fig., 2 tabs.

First, for reinforcing open-cut tunnel center pillars, design was devised so as to be suitable to construction environment in the subway yard. Important reinforcement materials are steel and filling materials; SS and a self-leveling material for building construction were chosen. The following construction work procedures are explained based on the actual construction: removal of interior materials of existing pillars and measurement of the actual size, high pressure water washing, steel plate fabrication, plate delivery to the yard, installation of steel plates, filler filling, painting. Next, on reinforcement of viaduct pillars on the ground, the reinforcement design concept is basically same as in the open-cut tunnel. Points of difference in design and construction are explained. On the countermeasure for prevention of viaduct falling for girder bridges without the falling prevention, countermeasure investigation and design work or installation work are being carried out. Seismic resistance evaluation and design of existing bridges, and construction work are explained. 13 figs., 1 tab.

    Since bunker fuel became extremely expensive through the first and second oil crisis, the share of steam turbines having lower thermal efficiency than diesel engines became less, and at present, almost all ships and vessels are equipped with Diesel engines. Also fuel consumption of a diesel engine has successfully been reduced by 24% in about 10 years, but the discharge of air pollutant in the exhaust gas has shown a trend of increase. Air pollutant in exhaust gas of marine engines which has not drawn attention so far has also begun attracting notice, and as marine traffic increases, some control of it will be made sooner or later. Hence economical and effective counter measures against exhaust gas are necessary. In this article, as measures for reducing NO {sub x}, discussions are made on water-emulsion fuel, humidification of air supply, multi-nozzle atomization, injection time delaying and SCR (selective catalitic reduction). Also measures for reducing SO {sub x} is commented upon and the continuation of superiority of Diesel engines in the future is predicted. 5 figs.

    Occurence probability and the size of the industrial accident (frequency and intensity) in Japan surpassed USA since 1970, having improved its safety record year by year. The decrease in the occurence of accidents in Japan is a result of various successful measures taken in various sectors of industries. Development of disasters prevention technology is always demanded in accordance with the progress of the science and technology. A methodology of disaster prevention measures comprises accident analysis (statistical or individual)(inductive or passive) and a safety principle (assessment of danger characteristics of the chemical substances, equipment examination technique, risk analysis, analysis of a near-mistake)(deduction or positive), block should support each other for establishing the safety technology. Types of the explosion accident involves a vapor mass explosion, BLEVE (Boiling Liquid Expanding Vapor Explosion), boil-over and vapor explosion, explosion due to run-away reaction, explosion of explosive substance and dust explosion. 13 refs., 6 figs., 2 tabs.

    A quantitative evaluation was made on techniques of CO{sub 2} immobilization utilizing organisms by referring to literatures. The techniques used for the evaluation were the following six ones: The first one is to plant trees on wastelands located in the tropics and the subtropics and CO{sub 2} is immobilized by grown trees. The second one is to compulsorily blow CO{sub 2} into water to immobilize CO{sub 2} by multiplicated microorganisms such as green algae. The third one is to multipulicate phytoplanktons by spraying deficient trace elements on oceans where trace elements such as Fe are deficient in spite of rich nutritive salts to absorb and immobilize CO{sub 2}in seawater. The fourth one is to multipulicate shellfishes in coastal regions to immobilize CO{sub 2} in seawater as their shells. The fifth one is to multipulicate many coral reefs in tropic or subtropic coastal regions to immobilize CO{sub 2} as calcium carbonate. The sixth one is to multipulicate large size seaseeds such as giant kelps in shallow seawaters to immobilize CO{sub 2} in seawater. The width of each applicabe area, immibilizingcapability of CO{sub 2} and the executing cost were considered to evaluate respective methods. As a result, the multipulication of marine planktons were thought most promising. 1 fig., 4 tabs.

    The paper studies the measures for reduction of environmental load of CO2 from the standpoint of chemical technology. As for methanol synthesis from CO2, accelerating of the reaction using Cu base compound catalyst is reported. Also, CO2 is methanated at high speed by low temperature waste heat using Ni-La2O3-Ru catalyst. Discussions are given on the subject for development of catalyst reaction relating to hydrogen production technology by methane reforming reaction using steam or CO2. Synthesis of polymetric materials by use of CO2 is also described. The paper mentions that it is indispensable to design high-function electrode and elucidate the reaction mechanism of electrochemical CO2 reduction for electrochemical and photochemical CO2 reduction measures. Moreover, in case of using solar energy, it is required to study photovoltaic excitation process in semiconductor electrode/ electrolyte solution interface. For production of hydrogen from CO2 by photosynthetic organisms and solar energy, the problem is control of inhibiting effect of oxygen combinedly produced. Described are production of polyhydroxy butyric acid and biodegradable polymer from CO2 and hydrogen by bacteria, and CO2 fixation imitating the enzyme reaction. 267 refs., 79 figs., 32 tabs.

    Full Text Available The Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE is a multi-expedition IODP drilling project aimed at drilling, coring, logging, and instrumenting the seismogenic zone of an active subduction margin , in a region thought to generate megathrust earthquakes of magnitude >8.0 on the moment-magnitude scale (Tobin and Kinoshita, 2006. The Nankai Trough, offshore of the Kii Peninsula, Honshu, Japan (Fig. 1 was chosen as the location for thisproject based on a number of scientific drilling proposals to IODP. These reviewed existing drilling data in the region, the long-term historical and recent record of great earthquakes, the social and societal relevance of the area, and the accessibility of the seismogenic zone to present drilling technology. The first stage of this multi-stage project was intended to accomplish a broad characterization of the shallow geology, geophysics, physical properties, heat flow, and fluid flow in a transect across the downgoing Philippine Sea Plate, the toe of the Nankai accretionary prism, the megasplay fault zone region on the continental slope, and the Kumano Basin that lies between the accretionary prism and the KiiPeninsula, on the continental shelf (Fig. 2.

    A review was given on the theory that sea level change having occurred in the past 20,000 years has given a great impact on patterns of upheaval and subsidence of the islands of Japan. Nakada has summarized distribution of underwater remains in the western part of Kyushu and estimated values of sea surface altitude in 6000 years ago, and used this conceptional chart to propose a crust upheaval mechanism by using hydroisostasy. More specifically, this is a model that crust which has subsided due to rise in the sea level has created flows of mantle, causing upheaval of the crust in land areas. This viewpoint requires further accumulation of data and verification of the theory in areas other than the western part of Kyushu. It is important to consider the effect of sea level change also in studying processes of subsidence and sedimentation in sedimentary basins including Osaka Bay. The currently available theories use analysis solutions on stratified ground, but does not consider topographical profiles from land areas to sea areas. As this topographical effect is thought extremely important, it is necessary to develop a two-dimensional cross section analyzing method by using the finite element method. 6 refs., 3 figs.

    After the oil shock, Saijou thermal power station converted its energy source into coal to diversify the power source. With rising operation rate at the plant after fuel conversion, leaky condenser tubes have increased. Such leakage concentrated especially in new 70/30 cupro-nickel tubes equipped in air cooling zones of the condenser. This report investigates the cause of this leakage and describes the study results on the corrosion prevention. Consequently, following two measures were taken: a measure to prevent local erosion of aluminum brass pipes by means of preventing inflow of foreign materials such as seashells; a measure to prevent corrosion of 70/30 cupro-nickel sulfide by strengthening the injection of ferrous sulfate and by test loading of coated tubes. As a result, no sea water was leaked. Moreover, it was found through the eddy current examination that sulfide corrosion of the new 70/30 cupro-nickel tubes was reduced by iron coat and the rate of losing its thickness decreased remarkably. 1 ref., 15 figs., 5 tabs.

    As for the levitation vehicle system, the vehicle is equipped with superconducting magnets and is levitated about 10cm by the electromagnetic force that works between the push coil and levitation guide coil laid on the ground and it runs 500km an hour. But, the running resistance and energy loss called as magnetic resistance caused by the electromagnet phenomenon that generates between the superconducting magnets and structures (steel products) generate. In this paper, the magnet resistance generated in guideway structure of superconducting magnetic levitation vehicle system and its countermeasures therefor are introduced. The main countermeasures against the magnetic resistance are as follows. The steel products have to be as arranged as separated from the superconducting magnets as far as possible in the permissible design limit. Based on the analysis results the low magnetic steel would be used in an area within 1.5m from the strand of the superconducting magnet. The contact resistance of the joints part of loop-shaped components would be bigger so as to do not cause the loop current. And the big component would be divided into small parts when it is used near to the superconducting magnets. 5 refs., 10 figs.

    Technical literature is referred to for the survey of recent trends in CFC (chlorofluorocarbon) phaseout in various countries overseas. The European Union will totally abolish CFC by the end of 1994 while other developed countries will totally abolish the same by the end of 1995 in compliance with the Montreal protocol. Many of the developing countries are actively striving to reduce CFC use with the help of the Multilateral Fund of Montreal. China and India have production facilities in themselves, and have not announced a phaseout program. There is a proposition for accelerating the regulation of HCFCs (hydrochlorofluorocarbons), but reliable substitutes for them are not yet available and their ozone layer restoring capability if used will be slight. It is feared that such will on the contrary retard CFC phaseout in developing countries. Accordingly, any abrupt acceleration of CFC phaseout implementation is inappropriate. Introduced in this report as fluorine-containing greenhouse gas-related information are a summary of the United Nations Framework Convention on Climate Change and the history of Intergovernmental Panel on Climate Change activities. According to an American survey, the aluminum industry emits 30,000 tons of CF{sub 4} and C{sub 2}F{sub 6}, and the semiconductor manufacturing industry 2,000-3,000 tons. As for SF{sub 6}, 5,000-8,000 tons are emitted mainly by the power industry. Measures for inhibiting them are being taken. (NEDO)

    Quantitative analyses of silicone migration into marble from elastic silicon adhesive were carried out by EPMA and LMA, and the amount of migrated silicone was calculated in terms of silicone concentration. By EPMA, silicone distribution into the area centering around the boundary between elastic adhesive and marble was clarified, and the migrating condition of silicone from elastic adhesive to marble was made clear. In the case of LMA, silicone concentration in micro-area in marble was measured to use the measured result for the succeeding analyses. As a result of the analysis, the trend of the change of silicone migration with the passage of time could be expressed by treating the silicone migration as diffusion phenomenon, and the depth of silicone migration could be quantified. It was confirmed that the cover primer applied at the back of marble to inhibit migration could prevent contamination of marble caused by silicone migration. The analytical method of this study seemed to be applicable to other stone materials or other adhesive and sealing materials. 14 refs., 12 figs., 2 tabs.

    The paper made an analysis of the heat island phenomenon in the Kanto area using 3-D numerical analysis models and a study on the effectiveness of the measures to prevent it. The models are composed of advection/diffusion models of heat/steam in the wind-velocity field and atmospheric air, heat diffusion models in the underground and undersea, and heat balance models on the ground surface and sea surface. In the calculation, a simulation was conducted of the case of taking the following three measures: the case where the exhaust heat was reduced 30% in the assumed typical day of summer; the case where the heat volume of buildings/trunk roads was reduced; the case where the evaporation efficiency of buildings/trunk roads was raised. The result of the study was as follows: The reduction effect of the exhaust heat is totally large, but precisely observing, some meshes contrarily showed rises in temperature in the suburbs. Also in the case of reducing the heat volume, the same phenomenon occurred, but the effect was large in the center of a city. It was found that the effect was unexpectedly large in the case of increasing the evaporation efficiency. 7 refs., 14 figs., 2 tabs.

    It was intended to confirm, based on various problems surrounding oil flow-out accidents, that oil fences whose use is first considered when an oil flow-out accident occurs cause oil leakage due to oil pass-through phenomenon as the largest defect in performance of oil fences. Therefore, oil fence performance was analyzed by using a simulation. Furthermore, several types of diffusion prevention and avoidance measures, and combinations thereof were evaluated by using multi-criteria analysis. It was also elucidated how recognitions on the importance of methods to prevent oil pollution differ depending on standpoints. Difference in oil flow-out prevention performance of oil fences due to variation in tidal currents was made clear by combining a diffusion simulation using the finite element method with the prevention performance of oil fences relative to the tidal currents. In areas with no good hydrographic conditions where pollution spreads rapidly, it is necessary to suppress oil diffusion by extending oil fences double or triple, and using gelling agents. 4 refs., 8 figs.

    This paper explains quantitatively performance of heat storage tanks contributing largely to levelling power loads, and promoting and spreading more effective use of unutilized energies. A model case was used to compare differences in effectiveness of unutilized energy utilization with and without use of heat storage tanks. The heat demand used was a value in a day with a peak room cooling demand, and a heat supply system using water heat source heat pumps that utilize sewage treated water was used to manufacture cold water. As a result, the effective utilization rate of unutilized energy was increased to about 1.3 times when heat storage tanks were used. Effectiveness of a heat storage tank comes from its capability that excess amount of cold water manufactured during nighttime when heat demand falls by utilizing sewage treated water is stored in the heat storage tank, and the stored cold water can be supplied being mixed with cold water manufactured during daytime when heat demand rises sharply in daytime. Because sewage treated water has its annual temperature difference stabilized at about 10[degree]C, a heat pump utilizing the sewage treated water can reduce power required to produce heat of 1 Gcal by about 40% during room heating and about 15% during room cooling over the heating tower type heat pump. 8 figs., 1 tab.

    Most of the limekilns now in operation in China are of the old type, demanding 30% more heat than limekilns in general use for instance in Japan. The survey assesses the effect of energy conservation or greenhouse gas reduction in case the old limekilns are replaced by new ones. For the implementation of this survey, the Benxi Iron and Steel Complex in Benxi City, Liaoning Province, China, who hope that their old limekilns will be replaced, is assumed to be the site of construction. A survey is conducted on this assumption, and the effect of greenhouse gas reduction in case new limekilns are popularized in China is also assessed. Under this program, the earth kilns will be abolished, to be replaced by 600 tons/day new limekilns. However, some of the single cylinder shaft kilns are to be retained. It is concluded that fuel consumption will be reduced by 7.49 times 10{sup 3} tons/year in terms of crude oil, fuel cost by 10,120,000 yuan/year, and CO2 emissions by 23,200 tons/year. The installation will cost 991-million yen, and the investment recovery period will be 7.9 years. The amount of metallurgical lime that China produces is 10-million tons/year, of which 70% comes from the old limekilns. After completion of the replacement there will be 33 limekilns, and the need is quite great. (NEDO)

    This paper reports the design and construction of landslide preventive construction at the site of the Yamasubara hydroelectric power plant (with a maximum output of 40,700 kW) and the result of slope stability verification after completion of the construction. The moderate slope on top of the primary slide has sands presumed to be colluvial deposit distributed with a depth of 10 m or more, where occurrence of a secondary slip was feared as triggered by the primary slide. The power plant protective constructions consisted of concrete walls to protect the entire power plant including buildings, and falling stone protective fences installed around the surge tanks. The temporary measures were so set that groundwater levels are lowered to a level that can assure the slide safety factor of 1.0 or more by means of drain boring using the down-the-hole hammer type. The permanent protective construction used rock anchors that are superior in constructability and economy. The stability of sliding slope faces was verified to confirm effects of the protective constructions. The verification included observations of groundwater level behavior, water well-up from drain holes, and movements in the slopes. The result showed that the protective constructions have give sufficient effects. Continued slope stability control is important. 16 figs., 7 tabs.

    Emission amount of nitrous oxide (N2O) from anthropogenic sources is analyzed, and reduction effects by the abatement technologies are evaluated. The concentration of nitrous oxide in the atmosphere continues to increase and emissions from agricultural and ecosystem sources are drawing particular attention. For the emission of N2O in Japan, 8.28 Gg-N2O per year is emitted from fossil fuel combustion facilities, 6.95 from waste incineration facilities, 22.5 from transportation vehicles including automobiles, 26.7 from the chemical industry including establishments engaged in adipic acid production, 2.1 from sewage treatment facilities including septic tanks, 6.3 from farmland, and 7.1 from livestock excrement. For the N2O abatement technologies for different sources, fuel improvement, high temperature combustion, acceleration of reduction decomposition reaction, and development of catalysts are significant for the combustion technologies. In connection with N2O discharged in the process of adipic acid production, major businesses have internationally committed to up to 99% abatement of the N2O emissions by 1998. With regard to wastewater and sewage treatment facilities and septic tanks, improvement in COD/NO-N ratio, retention period, pH level, and reduction process is pointed out. 204 refs., 70 figs., 53 tabs.

    In recent years, the techniques for the typical PC bridges shown in the title have been considerably developed in Japan. However, occurrence of characteristic vibrations of the parallel cables even at relatively low wind speeds are observed in many cases, for which an effective control means is inevitably required. In this report, an investigation of tests on effectiveness of 4 kinds of vibration control means carried out in a wind tunnel and its results are described. In the test, an elastic model of 3-dimension was used for 5 test cases including a case without any control means, and each case was explained and examined in detail. It was revealed that for a damping system, a considerably large damping effect was necessary to restraint the wake galloping, and the cable distance selected to be 1.5 times smaller or 6 times larger than the cable diameter was effective, and while vibration control wires were effective, the adjustment of the cable vibration frequency was ineffective.

    In recent years, long span of cable-stayed bridges is remarkable. The wind-induced cable vibration called as line vibration and wake galloping was given as an important problem not only in the steel cable-stayed bridges but also in the PC cable-stayed bridges. The technical engineers in design of the cable-stayed bridges have many times to confront the problems on the vibration control of cables, it is considered that sufficient understand of the wind-induced vibration and countermeasures for cables of the PC cable-stayed bridges is necessary. Many reports on the countermeasure examples and trend of vibration control centred on cables of the cable-stayed bridges have been published. In this paper, the wind-induced vibration of cables in the cable-stayed bridges was reviewed, the examples of countermeasures of vibration control on cables in the PC cable-stayed bridges was mainly introduced. The remaining tasks and future prospects on vibration control of the PC cable-stayed bridges were described. 14 refs., 13 figs., 4 tabs.

    Elaboration of the action plan for the New Earth 21 plan proposed by Japan in Houston Summit was researched. In fiscal 1995 three types of energy supply/demand scenarios, sensitivity analysis under various conditions, and cases presupposing CO2 emission regulations or not were evaluated by analysis toward 2050 using the New Earth 21 Model (NE 21 Model). Energy-saving is important, and CO2 recovery/treatment technology is introduced according to CO2 emission regulations, while attention is focussed on biomass energy. The issue of solar and wind power generation is cost reduction. In a presupposed horizontally integrated energy system, methanol represents an important intermediate energy. As a whole, CO2 reduction can be achieved by various combinations of energy-saving, introduction of regenerative energy, and CO2 recovery/treatment technology. Case studies of the action plan were conducted by unifying the evaluation criterion on coal IGCC, photovoltaic generation and biomass. The NE 21 Model was useful for elaboration of the reduction scenarios of CO2 emission. 26 refs., 84 figs., 28 tabs.

    Outlines of various energy supply/demand analytical models are surveyed. With environmental problems gathering importance, a number of models are being introduced in which energy supply/demand structures, long-term climate changes, and impacts of policy options on social economy are linked to each other. Some socioeconomic impact models cover a single country and others the whole world. They are various in type, ranging from dynamic optimization models to static balance models. Twenty-four models are chosen, and grouped into two types respectively covering Japan and the whole world from a geographical viewpoint and into three groups in view of their structures. Under an optimization model, such optimization is accomplished as economic growth maximization and energy cost minimization and so forth under given energy supply restrictions. Under a general balance type econometric model, an adjustment process in which capital and labor and production are coordinated across multiple departments is expressly stated. Under a partial balance type econometric model, a demand function for goods is given and optimum behavior such as consumption maximization is indirectly described. (NEDO)

    This paper describes a survey on problems in developing technologies for the global environment issues. Technological development of means to reduce generation of environmental issues and substitutive means for non-generation thereof is being moved forward specifically in the Sunshine Project and the Moonlight Project. The Chemical Technology Research Institute assumes that it has a responsibility to positively contribute to developing a technological system that matches the substance circulation mechanism of the earth from the fields of chemistry. Therefore, the Institute has organized working groups that have been identifying problems from their expertise standpoints and have been extracting study assignments. Subsequent to the Version I, the Version II has been compiled. The Version II takes up the simulation of global warming mechanisms, behavior of gases dissolved in oceans, and possibility of fixing CO2 in oceans. With respect to fluorocarbons, the Version II describes development of substitutive substances, their stability, combustion method as a destruction technique, and destruction by means of super criticality. Regarding CO2, the version introduces technologies to re-use CO2 as a resource by means of membrane separation, storage, and contact hydrogenation. The volume also dwells on CO2 reduction by using photo-chemical and electrochemical reactions, CO2 reduction and photo-synthesis by using semiconductors as photo catalysts and electrodes. (NEDO)

    It is necessary to establish scenarios for reducing CO2 emissions and for developing CO2 emission control technologies to obtain a global consensus, using appropriate analytical models. For modification of the DNE-21 (Dynamic New Earth 21) model, it has a category designated as innovative technologies not involving CO2 emission and an optional consideration for the absorption of atmospheric CO2 by biomass. A global carbon circulation model, including vegetation in its scope, is also incorporated. Major results of the simulation are shown. When 20% reduction in CO2 emissions is required for only OECD countries after the year 2020, it has been demonstrated that CO2 concentration in the atmosphere will reach as high as about 900 ppm in 2100 due to CO2 emission by developing countries, and will not be a tolerable level. Under the condition that CO2 concentration in the atmosphere is controlled at 450 ppm in 2100, the amount of renewable source of energy from photovoltaic power generation and biomass will increase and technologies of CO2 recovery and storage will decrease. Research and development of the production of methanol from recovered CO2 will be adopted as innovative technology for CO2 measures. 69 refs., 112 figs., 79 tabs.

    As part of the above-named effort, Japanese researchers were dispatched to overseas universities and laboratories for implementing joint researches into 11 subjects selected by the NEDO (New Energy and Industrial Technology Development Organization) screening committee. When the feedback of fruits of the researches to NEDO projects is taken into account, it may be said that the accomplishments, attained relative to the development of processes for the practical application of environmentally-friendly biomass energy and measures for promoting its adoption, will contribute to the completion of an environmentally-friendly energy production process, excellent in CO2 emissions reduction, in which biomass will be the raw material. In relation to the technology of installing pipes for CO2 discharge into the ocean, some of the dispatched researchers had an opportunity of studying technological problems not deal with under NEDO research and development projects. In the study of organized structures of low-purity CO2 bubble groups, a great contribution was made to the promotion of the NEDO-implemented project of evaluating the impact of CO2 storage in the ocean upon environments. The development of remedial technologies for Microcystis aeruginosa-invaded lakes by introducing environmental engineering assumes a very important position in the endeavors for environmental improvement in developing nations in the Asia-Pacific region.

    In order to serve for measures against global problems taken by Japan, joint research was carried out with overseas research organizations. The research project selected ten themes considering urgency, internationality and economic proliferation effect in areas to serve for solution of global environment problems. These themes include removal or emission control of greenhouse effect gases, measures against atmospheric environment problems such as acid rains and ozone layer destruction, prevention of ocean contamination, development and effective utilization of energies and resources. When the feedback of these themes to the NEDO projects is considered, the research achievements in relation with development of the acid rain monitoring system in particular support indirectly development of carbon dioxide fixation technologies. The research achievements in developing an environmentally friendly biomass energy manufacturing process and environmental effect evaluation thereon contribute as an effective process to carbon dioxide reduction using biomass as raw materials. The achievements in research of nonlinear interfacial properties and mixed phase turbulence of low-purity carbon dioxide bubbles contribute to a project related to storage of carbon dioxide in oceans.

    To investigate the energy demand and supply structure in Japan, the international trend of approaches to global warming problems and the mitigation options to global warming in the energy related sectors have been surveyed. For the United Nations Framework Convention on Climate Change, an Ad-hoc Group has discussed relevant topics after the 1st conference of the Parties. Meetings of the Group primarily focused on what objectives to set for the reduction of greenhouse gas (GHG) emissions in and in and after 2000. IPCC completed their Technical Paper in November 1996 in which technologies and measures to reduce GHG emissions and to enhance GHG sinks were analyzed and evaluated in various aspects. This Paper discusses about each sector of institutional buildings sector, transport sector, industrial sector, and energy supply sector. Especially, in the energy supply sector, promising approaches to reduce future emission include more efficient conversion of fossil fuels, switching to low-carbon fossil fuels, decarbonization of flue gas and fuels, CO2 storage, switching to nuclear energy, and switching to renewable sources of energy. 5 refs., 2 figs., 14 tabs.

    This paper explains the involvement of the global environment action plan of Japan Society of Civil Engineers, Agenda 21, with civil engineerings and global environmental problems, as well as the global environment action plan. Global environmental problems require handling the matters in three ways: identification and elucidation of events, effect analysis estimation, and alleviation, avoidance and prevention of the effect. Settlement and proliferation of civil engineering technologies transferred to developing countries demand indispensably understanding such features of the developing countries as social and economic conditions, natural conditions, climates, histories, races, and cultures. Realizing the sustainable development requires the followings: formation of civil engineerings that contribute to improving global environments; development of civil engineerings that make coexistence of human being and other living organisms possible; analyses of effects and mechanisms of global warming and weather change and the corresponding technique and system development; and development of techniques to build resource circulating type national land and cities. It is also essential to move forward positively structuring civil engineerings that contribute to solving such global environmental problems as acid rains and marine pollution, and technical development thereof; providing guidelines on execution of international civil engineering constructions, and technical development thereof; developing civil engineerings in developing countries and assisting training of people.

In general, ions contained in the groundwater originate in rainwater and falling matter; human activity; volcanoes and hot mineral springs; rock and soil; etc. The problems with the quality of water in landslided areas are Na {sup +} and Ca {sup 2} as positive ions and HCO {sub 3} and SO {sub 4}{sup 2 {sup minus}} as negative ions. It can be understood that change in the chemical composition of the groundwater caused by the flow of the groundwater is closely related to the weathering of rocks. Examples of investigation on groundwater flow by chemical injection are introduced. The composition of gases dissolved in groundwater is as important as the dissolved components for the study of the origin and history of groundwater. 34 refs., 16 figs., 7 tabs.

    International Panel on Climate Change (IPCC) published the 1st assessment report in 1990 and the 2nd report in 1995 since its establishment in 1988, and is promoting the 3rd research and analysis. Among them, this report describes the study on technology transfer for efficient energy consumption. For stabilizing greenhouse effect gas concentrations in the air, strong control of such gas emission is indispensable, and a role of technology is important for the control. For overcoming some weak points for climate change, practical use of applicable technologies is necessary over a certain period of time, and technology transfer is essential in each country and all over the world. For promotion of such approach, the analysis and evaluation for technology transfer and diffusion are useful in addition to reports on technology itself. Based on such understanding, IPCC has promoted preparation of the special report on methodological and technological issues of technology transfer since 1997. Its approval at the IPCC general meeting is expected in late 1999 or early 2000. Some chapters related to efficient energy consumption are presented. (NEDO)

    The world energy demand is increasing with the development of the world economy and the improvement of the life level. In view of the future economic development and population growth, the world energy demand will considerably increase especially in the LDCs. Since the oil crisis, saving of energy and material were effectively executed, thus significantly reducing the energy requirement per GNP. However, in the recent several years, the conciousness of energy has become diluted, causing considerable consumption in larger size and higher grade products, thus increasing the non-industrial and transportation consumption. This report considered the effective use of energy and the nuclear application. It is to be noted that the accident frequency in the Japanese nuclear plants is much less than the other countries. The coal utilization requires further technical development in view of the environmental problems. Other substitutible energies are all weak in competition and cannot be expected utilizable in large scale for the time being. This report also referred to the oil problem. 9 figs.

    For the purpose of studying how the energy supply/demand structure in Japan should be, a report on the secondary IPCC (Intergovernmental Panel on Climate Change) evaluation was analyzed. Possibilities of reducing the world CO2 emissions in association with the energy consumption were studied in the five assumed cases. Every case says that CO2 can be reduced to 1/3 of the 1990 level by 2100. In a case of the use of biomass as main fuel (1), the use of primary energy is suppressed to two times the 1990 level, and photovoltaic/wind/biomass power generation is introduced in a large quantity. Synthetic methanol and hydrogen are used for transportation and commercial/residential use fuels. There are four more assumed cases: the use of nuclear power as a substitute for renewable energy in the power generation in (1), the use of natural gas of 1.5 times that used in (1), the substitution of coal for biomass used in (1), and the assumption that the demand for primary energy in 2100 will be twice that used in (1). In Japan it is assumed that basically the nuclear power generation will be expanded, that the photovoltaic and waste power generation will be introduced in a large quantity, and that synthetic methanol and hydrogen are mainly used as transportation and commercial/residential use fuels. It is necessary, therefore, to analyze conditions under which the quantity introduction of such non-fossil energy is made possible. 11 figs., 31 tabs.

    Together with the global warming problem, it becomes important to elucidate the carbon dioxide circulation in global scale mechanism. Within a part of that elucidation, explanation of function and ecology was made of coral reef, fixing carbon dioxide through two passages, ie., formation of potassium carbonate skeleton and formation of organic matter. The coral reef is judged to become effective sink of carbon dioxide by the photosynthesis by symbiotic seaweed in coral body and coral formation of potassium carbonate skeleton. The coral reef is higher than the tropical rain forest in diversity and productivity of biological matter. In addition, the formation of potassium carbonate also fixes carbon dioxide. Its producing rate of organic matter is 2.5kgC/m {sup 2}/year, which is 20 times as high as that of offshore region. Also, its sedimentary rate is more than several hundreds of times as high as that by Foraminifera in the offshore region. Therefore, its effective control is important, though it still has unknown points. 22 refs., 13 figs., 1 tab.

    The paper studies the measures for reduction of environmental load of CO2 from the standpoint of chemical technology. As for methanol synthesis from CO2, accelerating of the reaction using Cu base compound catalyst is reported. Also, CO2 is methanated at high speed by low temperature waste heat using Ni-La2O3-Ru catalyst. Discussions are given on the subject for development of catalyst reaction relating to hydrogen production technology by methane reforming reaction using steam or CO2. Synthesis of polymetric materials by use of CO2 is also described. The paper mentions that it is indispensable to design high-function electrode and elucidate the reaction mechanism of electrochemical CO2 reduction for electrochemical and photochemical CO2 reduction measures. Moreover, in case of using solar energy, it is required to study photovoltaic excitation process in semiconductor electrode/ electrolyte solution interface. For production of hydrogen from CO2 by photosynthetic organisms and solar energy, the problem is control of inhibiting effect of oxygen combinedly produced. Described are production of polyhydroxy butyric acid and biodegradable polymer from CO2 and hydrogen by bacteria, and CO2 fixation imitating the enzyme reaction. 267 refs., 79 figs., 32 tabs.

    The electric power industry has made stable and economic power supply possible by advancing diversification in power sources and shifting the petroleum supply sources to southern countries and China. The cost constitution of the electric utility business in the fiscal year 1992 was such that the ratio of fuel cost is 15.9% against the total cost amount of 13 trillion 399.3 billion yen. As opposed, the fuel cost percent in the fiscal 1980 was 37.7%. This means that the effect of the fuel cost on the total cost has become smaller even if the fuel cost varies as a result of external factors including fluctuation in foreign exchange rates. Peaks in the power demand have been recorded in day time in high summer when air conditioning demand increases, which have been growing year after year. Expenses to maintain facilities and functions to deal with this demand increase have been increasing. The owned capital ratio in the electric power business was 15.7% in the fiscal 1992, which is by far lower than the average of whole industry of 28%. Execution of measures against the power peaks and improvement of the management constitution are the problems posed on the electric power industry. 4 figs., 1 tab.

    Recently, many of the low temperature materials such as LNG and LPG used as an energy substitution for petroleum were stored in the reclaimed land of the sea side district, however, it is necessary for those storage methods to enlarge sites. Therefore, it was considered to directly store the low temperature materials in openings excavated in the rock mountains. However, countermeasures for leakage of liquid and cold gas from cracks in openings would be an important subject. In this study, as a countermeasure for leakage of liquid and cold gas in the case in which low temperature materials were stored in openings in the rock mountains, the lining of resin materials on the surface of openings was proposed. Characteristics of strength and deformation and values of the thermal physical properties for the resin materials at the low temperature were obtained by experiments. This material was compared with granite supposed as a parent rock, and the thermal property of the resin materials was understood. Next, an analysis was conducted in the case of using the resin materials as a lining, the behavior of the surrounding rocks of the openings and the stability of the lining were investigated. 17 refs., 25 figs., 2 tabs.

    Kansai Electric Power Co., Inc., is constructing in Maizuru City a coal-fired thermoelectric power plant to operate two 900,000kw generators. The result of a preliminary survey predicted an encounter with boulders 50-900mm in diameter to obstruct the pile driving process. In a basic pile driving arrangement, a boat mounted with a 1600tf capable fully rotatable crane and a boat carrying an automatic lift type working platform are operated, and a pile is driven under the guidance of a keeper aboard by a vibratory hammer down until it can stand erect on its own. Next, the vibratory hammer gives place to a 50tf-m capable hydraulic hammer, which drives the pile further down until it lands at a depth level with prescribed bearing power. In case pile penetration under a vibratory hammer becomes difficult (at a shallow level), the pile is pulled out, a casing pile is driven in, and then boulders are removed by hammer gloves. In case boulders emerge during hydraulic hammer operation (at a relatively deep level), since dealing with such is beyond the capacity of hammer gloves, pile installation by inner excavation is performed by driving with a heavy bob. The bob is provided with multiple blades on its head, with water and compressed air supplied continuously for the bob to fall freely to crush boulders and to perform excavation at the same time. Mucking is accomplished using an air lift type reversely circulating water system. 1 ref., 8 figs., 2 tabs.

    With the progress of power-electronics, a inverter has been generally applied to building facility equipment. This equipment go by chapping a current in high frequency, so secondarily generates electromagnetic noise. The characteristics and propagation of electromagnetic noise generated by an elevator machine were measured. From this, it was recognized that high-level spectrum was included in the frequencies under 100kHz, and electromagnetic noise was scattered a wide area on the roof and the highest floor of the building. By intercepting the conductive noise on the motor main distribution line, the area influenced by the noise was restricted to only a small area around the elevator machine room. 4 refs., 8 figs., 2 tabs.

    Under the hydrogen-utilizing international clean energy system technology project WE-NET (World Energy NET Work) in fiscal 1998, researches and studies were conducted to clearly define safety designs and to improve on accident-and-safety analyses. In relation with system safety design, investigations continued into Japanese and foreign manuals and regulations about the handling of hydrogen and its peripherals, and safe design guidelines (draft) were compiled. Anomalies and accidents supposed to be typical of each of the systems concerned were investigated. As for accident-and-safety analyses, incorporation of a turbulence model was studied in relation to models representing the leak, evaporation, and diffusion of liquid hydrogen, and improvement was achieved when the scope of evaluation was enlarged concerning the hydrogen detonation model. The integration of the two models was discussed for the due evaluation of a series of processes of liquid hydrogen leak, evaporation, diffusion, and detonation. Calculation was performed for two assumed accidents, and the results were found to justify the integration of the two models. (NEDO)

    With the study focused on the possibility of technological breakthroughs, from the results of the survey on industrial technological trend and the preliminary examination concerning the technology for reducing nitrous oxide (N{sub 2}O), proposals were made on the direction of the future R and D. As technologies for reducing N{sub 2}O generation in the furnace, there are improvement of combustion process and development of high performance fluidized mediums. These are definite in their targets and methods, and are applicable as urgent countermeasures for immediate effects as well as highly reliable in the process of implementation. Meantime, as technologies for reducing N{sub 2}O in a flue gas by catalysts, there are decomposition or reduction of N{sub 2}O in the middle-temperature range (300-400 degrees C) and in the low-temperature range (lower than about 150 degrees C), suppression of N{sub 2}O as by-product generated in the NOx treatment process, and development of catalysts. These are applicable for a broad range of N{sub 2}O sources including automobiles. In addition, requiring no great modifications in the equipment infrastructure, these technologies will seem to spread immediately to a broad range of fields once an effective catalyst is developed.

    This paper summarizes an outline of a prepared draft of a `guideline for anti-earthquake measures for a clean room`. The guideline is intended to prevent earthquake disasters to facilities and their peripherals. Structural and non-structural members are classified according to criticality, and each category is provided with a grade target for safety performance. Horizontal withstand force required to be maintained, horizontal seismic force for design purpose, and values of the design horizontal seismic force multiplied with criticality coefficient are treated as required safety for architectural structures, non-structural members, and building facilities (devices and buildings). Structures to reduce disturbance are classified into the following structures: an anti-seismic structure of elastic strain energy resisting type or plastic hysteretic energy absorbing type, a vibration controlling structure of damping providing type, mass adding damper type or counterforce providing type, and a vibration absorbing structure of slide mechanism type or soft and elastic material supporting type. The damping providing type of the vibration controlling structure increases damping constant, and reduces stress shear force and response displacement. The vibration absorbing structure extends vibration period of a structure. A vibration absorbing device consists of supporting function to support a structure in a stable condition and a damping mechanism to suppress transformation. 6 figs., 11 tabs.

    The paper arranged the present situation and the problems of environmental cooperation for developing countries, and studied based thereon how to cooperate in environmental protection for developing countries in the future. At the same time, it arranged the problems/subjects posed when environment-related companies in Japan try to transfer environmental technology to developing countries, for the purpose of using them as data in studying possibility of reviewing the environmental cooperation presently conducted. A view on environmental cooperation is that as security of mankind, it is necessary to help developing countries in technology/knowledge/fund. However, a trial calculation indicated that the initial investment of 11.1 trillion yen is needed only for desulfurization and water treatment in China and ASEAN countries. Such a huge amount of money cannot be paid at all even by developed countries. As the support of environmental protection measures, the one also including energy and resource is needed. Further, the support of environmental protection measures should be the one that has the exhibition effect and influential effect, promotes efforts of developing countries' own, and pushes independent environmental measures forward. From this point of view, a study was made on what the details of the environmental cooperation should be like. (NEDO)

    This paper describes development of large-capacity UPS (uninterruptive power source) for large-capacity computer systems by Fuji Electric. This UPS is composed of a rectifier, inverter, transformer, and ac filter. The rectifier and inverter are composed of the same IGBT power modules. The IGBT power module has an integrated structure consisting of IGBT, gate driving circuit, snubber circuit, electrolytic capacitor, cooling fin, and fuse. Downsizing of snubber circuit and improvement of mounting efficiency were realized by developing a large current substrate with small wiring inductance. Advanced input/output performance and control characteristics of USP were realized by the digital control using RISC and DSP of high-speed processor. For the inverter control algorithm, PWM pulse can be calculated using parameters derived from the state equation of the main circuit constants. The output voltage distortion factor less than 5% was realized at the nonlinear load of 100%. The UPS systems in the out-sourcing business and large-scale business center are illustrated as examples. 6 figs.

    The general analysis/assessment method of a fossil fuel cycle was studied. Seven kinds of power generation plants such as LNG cycle and coal cycle ones, and four kinds of transport and treatment systems of recovered CO2 such as ocean and underground systems were studied as case studies on life cycle analysis. As data necessary for life cycle analysis, the database was constructed which stores the facilities and operational energy required for a total energy system from mining of fossil fuel to treatment of recovered CO2, and the quantity of environmental waste such as CO2 emission. As a result, the decrease rate of energy balance defined as ratio of input energy to power plant output was estimated to be 14-43% and 20-60% in LNG cycle and coal cycle, respectively. Even if the recovery rate of CO2 in power plants reached 80-90%, reduction of total CO2 emission was limited to only 20-40% because of CO2 emission during mining, liquefaction and transport of fuel. 168 refs., 48 figs., 102 tabs.

The themes were 'a sustainable energy strategy for the nineties', 'industrial structure change and energy problem', and 'new energy and the global environment'. The panelists were from Sweden, France, Thailand, U.S.A., and Japan. The main subject was energy security, in which discussion was held on the uneven distribution of oil resources in the Middle East and political instability in the region and on counter measures against global warming problem. The discussion on the latter subject showed that a limitation exists in the total consumption of fossil fuel in the world, and that energy policies were meaningless unless they were on a global scale. As the concrete measures, energy conservation technologies and regenerative energy utilization technologies need to be developed and spread, for which emphasized was the spread on a global scale, namely, the necessity of international cooperation and an international propulsion system.

    As the research study contributing to implementation of 'The New Earth 21' proposed by Japan at the Houston Summit in 1990, a DNE21 model was developed as a quantitative assessment model for global warming preventive technology, heightening of efficiency of the global energy supply/demand system, conversion to energy sources of low carbon emissions, etc. In the project of 'The New Earth 21,' economy and environment can be compatible centering on developed countries' technical development and technology transfer to developing countries. In FY 2000, for heightening applicability of the DNE21 model, the world, which was used to be divided into 10 regions, was divided into 54. At the same time, a prototype model was constructed in which cities in the region were divided into three cities: large; medium; small. Using the DNE21 model, evaluation was made of effects of uncertainties such as population, economic growth, final energy demand and cost as preconditions of the model on the optimization of global warming preventive measures. Further, technologies which are expected to be important for global environmental policy in the ultra-long term were listed up to estimate the potentiality. (NEDO)

    Japan proposed in the Houston Summit the New Earth 21 to be carried out with technology development and technology transfer, and to make a concrete development of the project, Japan also proposed in the Tokyo Summit a TREE Plan for working out comprehensive strategies of the innovative technology development. In the CO3 Kyoto Conference in 1997, numerical targets for developed countries were determined which have legal binding force for control/reduction of greenhouse gas emissions in the term of 2008-2012. It was agreed to urge developing countries also to play a certain part in the project through the clean development. Therefore, the paper made quantitative analysis of important CO2 prevention technologies, technology transfer costs, and economical assessment by energy conservation. As a model, the DNE 21 model was upgraded and used into which CO2 prevention technologies, energy, economy and climate changes were integrated. In fiscal 1997, the following were carried out: collection of data on important CO2 prevention technologies and systems and analytical assessment using the DNE 21 model, CO2 reduction and selection of energy technology, assessment of energy system costs, construction of the unified DNE 21 model, and opening of the international workshop. 62 refs., 98 figs., 34 tabs.

    The above was conducted by Research Institute of Innovative Technology for the Earth (RITE). Worldwide collaboration is mandatory for the settlement of environmental problems for the earth, and RITE is positively promoting its interaction with research institutes abroad. In fiscal 1998, it sent research teams to government organizations and research institutes in Europe and America for studies there. A study in Europe involved the preparation of chemicals from CO2 by virtue of novel biotic reactions, and RITE's microbial molecular function laboratory plans to start a leading study in fiscal 1999. In relation with environmental impact reducing technologies using sunlight-aided photocatalysts, visits were paid to three research institutes in America. RITE itself has developed a powdered semiconductor catalyst and is engaged in the study of producing hydrogen by decomposition of water using solar energy. Concerning the production of saccharides out of farm wastes remaining unused, researches were made into the feasibility of joint studies with some advanced research institutes in America. Discussions were made about the performance- and stability-related improvement of enzymes usable for the decomposition of biomass, the analysis of biological environmental circumstances that substance yielding microbes find themselves in under anaerobic conditions, etc. (NEDO)

    Assessment and examination were conducted on the scientific/technological aspect, environmental aspect and economic/social aspect concerning measures for mitigating climate change, as a part of international cooperation in global warming issues. In the development of assessment methods for cost analysis, it revealed that, in the activities for mitigating emission of greenhouse effect gases (GHG) or for increasing carbon sequestration, benefits of the mitigation sometimes surpassed their cost, allowing the society to benefit from the mitigation. In the examination of problems in technology transfer and their solutions, it was found that, in order to attain successful transfer, partnership among the parties interested was essential and that each government was capable of promoting such partnership. In the assessment of various policy options, the situation in the U.S. is such that the market aspect of GHG emission permit and credit trading is rather weak because of immaturity in a legal framework on GHG emission trading and because of undefinedness in the systems of the Kyoto Protocol and in the possibility of its validation. However, the reason enterprises are actively participating in the early market is that they plan a risk-hedge for example in anticipation of tighter regulations in the future. (NEDO)

    For the establishment of a CO2 measures introduction scenario which the world would accept, the latest information was collected, the DNE21 (Dynamic New Earth 21) model was improved, and simulation was reviewed. In fiscal 1998, simulation was performed for each district using an LDNE21 (Linear Dynamic New Earth 21) model, and an energy flow chart, energy balance table, and trade table were prepared and subjected to detailed deliberation. Studied were also conducted about the changes to occur in methanol production when the natural gas reserves and plant cost data were given different values. In the DNE21 model, the 'macro economy model' and 'warming damage function' were integrated, and simulation was performed for verification. Using a standard model compatible with COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change), comparison was made between a case in which different CO2 emission constraints were imposed on the advanced area and developing area separately and a case in which one and the same constraint was imposed on the world as a whole, and calculations were made about CDM (Clean Development Mechanism).

    As a part of the international cooperation for the global warming problem, evaluation/study were conducted on policy to lessen climate changes from viewpoints of scientific technology, environment, and economy/society. In the development of evaluation methods on cost analysis, the following were pointed out: Changes in resource utilization brought about as a result of the policy are all needed to be numerated; In resource, clean air and water, and also abolition of price barrier and prices now in force are included. As subjects on the technology transfer, cited are barriers in aspects of organization/system and barriers in aspects of economy/finance and society. Especially, it was pointed out that it is necessary to exchange the persons concerned in the industrial sector. Of various optional policies toward the prevention of global warming, the Kyoto mechanism not only has an economical merit of the use of low cost option but can be fairly promising from an environmental viewpoint of internationally controlling the greenhouse effect gas emission, if the characteristic of practically using the market can be so designed that it fulfills its function.

    Described herein are the results of the study on possibility of research exchanges, conducted by Research Institute of Innovative Technology for the Earth (RITE) in FY 2000. For development of thin-film catalysts, HTE, a venture developing combinatorial chemistry application to catalysts, is a potential partner for the exchanges. One of the technical problems involved in underground sequestration of CO2 relates to evaluation of the reactions between CO2 injected under pressure and the surrounding rocks. It is a less site-specific theme, and preferably pursued through international networks. The RITE delegates have visited the British Geological Survey, Canada's Alberta Research Council, and US's Pennsylvania State University, Rice University and Chevron Petroleum, finding research exchange possibilities in all of these organizations for broad technical themes related to underground sequestration of CO2. For energy conversion technologies using biomass resources as the source materials, the potential partners for the research exchanges include Swedish Royal Institute of Technology, Belgium's Catholic University of Louvain and Spain's University of Zaragona which leads researches in production of gases from wastes and biomass.

    Discussions were given to reserve global environments on reducing dependence on fossil resources and more effectively utilizing wood resources. Economically utilizable amount of wastes from lumbering factories reaches about five million tons annually. Discussions were made on a ligno-bioprocess that uses these wastes. The current quantitative production efficiency of cellulase by means of bacterial breeding is very high. A problem is production of ligninolytic enzymes, to which application of the recombinant DNA method is indispensable. Combination of steam explosion with biological decomposition or the organosolv process is an effective method for lignin decomposition. Decomposition of cellulose by using the ultra critical water method is worth noticing. With respect to hemicellulose utilization, production of cellulose derivatives, biodegradable polymers and oligosaccharides would be conceivable by means of esterification and etherification. Vanillinic acid, adhesives, resins and lignin-based polymer materials could be manufactured from lignin. Material cost for these products accounts for about 35% of the product price, thus making the lignochemicals promising commercial products. 301 refs., 71 figs., 39 tabs.

    The tropical forest regeneration technology research group of Kansai Electric Power Company and Kansai Environment Center has been performing the research and development of tropical forest regeneration technology jointly with Indonesia since fiscal 1992. The group was awarded with the Global Environment Technology Prize from Nihon Keizai Shimbun, Inc. As a result of stringent examination on 97 applications, being two times as many as in usual years, the group received high evaluation on the originality, reality and possibility of proliferation of its research, and impacts given to the societies. Two other groups were also selected. The achievements were reported by the representative of the group in the award commemoration lecture at the global environment economist summit held by the Nikkei press the same day. Conventionally, afforestation done with considerable efforts has often been lost by forest fires and slash-and-burn farming, whereas the present research aims at establishing a comprehensive afforestation technology considering social and economic aspects, and CO2 fixation. As one of the choices of flexible measures as a result of the effect of forests having been recognized in COP3, frameworks for utilizing the mechanisms of joint implementation and clean resource development were introduced. Ever increasing expectations are placed on the achievements of the present research works. (NEDO)

Toward the target of GHG (green house effect gasses) 550 ppm, sensitivity analysis using a linear DNE21 model was replenished, with model analyses made on a scenario concerning the countermeasure technologies/systems. In other words, performed were the improvement of accuracy by the renewal of data, sensitivity analysis concerning CO2 collection/processing technology and nuclear energy, analysis of the international regulation for controlling CO2 concentration under 550 ppm in the air in the year 2100, and sensitivity analysis on increase in per capita energy demand in Asia. Overall assessment of global warming problems was upgraded for the purpose of enabling the assessment from the consumption maximization point of view, taking into consideration cooling effects of SOx and economic growth. Potentiality assessment in rational use of energy was reexamined because energy conservation played an important role. That is, in DNE model, the data were examined of OECD signatories and developing countries from 1970s concerning natural gas, petroleum, coal and electric power, with the long-term cost flexible value estimated. In addition, feasibility was assessed of rational use of energy from energy GNP unit. (NEDO)

The themes were 'a sustainable energy strategy for the nineties', 'industrial structure change and energy problem', and 'new energy and the global environment'. The panelists were from Sweden, France, Thailand, U.S.A., and Japan. The main subject was energy security, in which discussion was held on the uneven distribution of oil resources in the Middle East and political instability in the region and on counter measures against global warming problem. The discussion on the latter subject showed that a limitation exists in the total consumption of fossil fuel in the world, and that energy policies were meaningless unless they were on a global scale. As the concrete measures, energy conservation technologies and regenerative energy utilization technologies need to be developed and spread, for which emphasized was the spread on a global scale, namely, the necessity of international cooperation and an international propulsion system.

Specifications for system introduction are about maker selection, operation system, detailed schedule for introduction, etc. RITE inhouse database has problems on its operation system and its maintenance cost, and is apt to be high in a construction cost in comparison with a utilization factor. Further study is made on its introduction. Information provided by the inhouse database is only the one owned by the organization, and information outside the organization is provided by the external database. The information is registered and selected by the registerer himself. The access network is set by personal computer network at the beginning and is set to transit to INTERNET in the future. For practical construction of the system, it is necessary to make user`s detailed needs clear for the system design and to adjust functions between hardware systems. 32 figs., 9 tabs.

    Promotion of development of hydraulic power and others as fossil fuel alternative energy sources is one of the most important measures for solving the global environmental problems. This draft plan proposes, first of all, to conduct surveys on hydraulic power resources on a global scale, to collect the basic data for development of the energy sources. It is estimated that developed hydraulic power resources account for approximately 14% of the total developable resources, the remainder being left untouched. By region, these percentages rise to approximately 55 and 45% in North America and Europe, respectively. These percentages in Asia, Africa, Latin America and FSU are significantly lower, and their undeveloped resources are estimated to total approximately 6 times as large as those already developed worldwide. It is expected that the hydraulic power resources are surveyed on a 10-year plan (1991 to 2000) with a total budget of 30 billion yen, to collect the data and establish the databases in cooperation with international organizations, e.g., UN organizations, regional organizations (e.g., ASEAN organizations) and newly founded organizations.

In the U.S., a report was taken up from Executive Office of the President which is entitled `the federal government R and D of energy for solution to problems in the 21st century.` The report made analyses of the federal government R and D of energy and at the same time recommended an increase in R and D budget and reinforcement of the organization of the Department of Energy. In Europe, the carbon tax, CO2 tax, energy tax, etc. are introduced or studied for reduction of CO2 emissions. OECD made public a report approved in May 1997 which is entitled `the environmental tax and green tax reform.` Also studied were the introduction and effects of the carbon tax aiming at reducing CO2 emissions in developing countries. More attention is being paid to economic effects predicted in case developed countries reinforce various kinds of measures for targeted reduction of greenhouse gases. 2 figs., 4 tabs.

    The result of a survey which involves a 520km-long gas pipeline (Shebelinka-Dikanka-Kyiv) modification in the Ukraine is described, which will promote joint implementation programs under COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change). Since the greenhouse effect of methane gas is 21 times as serious as that of CO2, it is important to ensure good maintenance and structural soundness for natural gas transporting pipeline systems. The currently available Ukrainian gas turbines and compressors are so obsolescent that their efficiency rate is as low as 23%. The rate will rise to 36% when the old ones are replaced by high power equipment capable of high efficiency combustion. Pipelines will be checked for deterioration due to stress corrosion cracking and dangerous pipes will be replaced, with attention paid particularly to joint sections. It is expected that there will be a greenhouse gas reduction of 512,000 tons (in terms of CO2) and a saving of 103,000 tons on fuel (in terms of crude). Balance is tentatively estimated in case the expected reduction in emissions is transacted in emission trading. Profitability will occur, in view of profit from emission trading and gas sales revenue after gas leakage prevention thanks to project implementation, when the emission right sells at 30 dollars/ton or higher. The rippling effect will be great now that the Ukrainian pipeline system is quite extensive (with 30% thereof superannuated). (NEDO)

    Upon the request from the Ministry of Agriculture of the Polish Government, a survey has been performed on three sugar production factories (Lesmierz, Lapy and Werbkowice) in Poland in relation with conservation of energy and reduction of warming gas emission. The survey has been made from the following two aspects: improvement of energy utilization efficiency in the sugar production processes, and efficiency improvement and fuel conversion in the boilers being the energy supplying source. As a result of the discussions on the sugar production process improvement, annual fuel conservation of 304,495 GJ (or 12,688 tons as converted to coal) in total for the three factories, or the energy saving rate of 28% was obtained. Regarding the greenhouse gas emission, an effect of reducing 25,235 tons, or a reduction rate of 27% was achieved. In the combination of the sugar production process improvement and the boiler improvement, the fuel conservation will be 18,363 tons as converted into coal, and the reduction of the greenhouse gas emission will be 56,107 tons. However, when based on the present coal price and natural gas price, the improvement efforts will not be realizable economically for both of Lesmierz and Werbkowice factories, hence comprehensive judgment is required from the viewpoint of the fuel price and environment preservation expense in the future.

    In the Asian region, for the purpose of grasping effects of both economic growth and effective energy consumption, an analytical tool added with a computational function was developed with the interindustrial relations table as database for the analysis of the present situation and the simulational analysis. In the analysis of the present situation, changes between the two time-points, 1985 and 1990, were analyzed using the developed energy consumption table and the CO2 emission table. The energy consumption amount is increasing with the growing economy. However, the energy unit consumption is decreasing in countries except Korea, the Philippines, Singapore and Malaysia. The trend is that the energy consumption is becoming effective and the CO2 emission amount is decreasing. As an example of simulating the introduction effect of energy saving technology, the simulation was conducted on the three: iron steel, paper/pulp, and cement in Indonesia. As a result, the decrease in energy consumption was shown in paper/pulp by 48%, in cement by 16%, and in iron/steel by 16%. The same was also indicated in CO2 emission. (NEDO)

    With an objective to promote capital investments that have been fallen because of the recession in Japan, the Petroleum Department of the Agency of Natural Resources and Energy has decided to take the following measures limited to one year for application. The measures consist of the taxation system for high-level energy saving investment promotion and the taxation system for small business machine investment promotion. In the former system, facilities that are effective for promoting rationalization and serving for environment preservation are admitted a special depreciation of 30% (36% for small business) on acquired prices or a tax deduction of 7% (8.4% for small business). Tax deduction of 7% (8.4%) is granted on leased assets. However, machineries are subject to a requirement of the price to be higher than 2 million yen (2.7 million yen in leasing). As a result, petroleum product shipping facilities are also covered by the taxation measures. The latter system, which is intended to promote investments by small business corporations, admits a special depreciation of 30% and a tax deduction of 7% for machineries acquired at prices above 2 million yen. Electronic computers and facsimile machines are also subjected to the taxation measures if their prices are higher than one million yen.

    Tokyo Electric Power has realized a peak shift of 5% for the maximum power demand by various measures to cope with increasing power demand and differential rate by time zone, including expansion of the differential rate system and heat-storage systems. Some of more notable recent techniques are eco-ice and eco-vendor systems, the former storing ice in the heat-storage tanks and the latter strongly cooling vending machines during nighttime. The NAS battery system is being developed as the new technique for load leveling. The energy-related advisory organ for Minister of International Trade and Industry asks each industrial unit to save at least 1% of power on the annual average as the energy-saving measure towards 2000. The energy-saving measures promoted by the government for the coming winter are controlled release of wastes, efficient use of power, setting room temperature at 19{degree}C or lower and voluntarily refrain from commuting by cars. The US power industry is abandoning the concept of DSM in the midst of deregulation and increased competition, and cutting budgets for new energy development. California`s SCE is promoting energy-saving through expanded use of high-efficiency motors, accurate grasp of customers` needs and publicity activities through internet systems. 4 figs., 1 tab.

    A geotextile drainage material called ART-DRAIN has been developed. It was applied to temporary roads in a tunnel, to evaluate its permeability through a long-term permeability test using a model. The ART-DRAIN is a drainage material for protecting the roads from muddy conditions in a tunnel due to spring water. A filter for permeating fine soil particles was employed to keep the permeability. From the long-term permeability test using a model, appropriate permeability of ART-DRAIN was maintained for three years without blinding. There was only a slight inflow of fine grain soils into the ART-DRAIN. It was confirmed that the permeability was not obstructed by the fine grain soils. The ART-DRAIN was applied to tunnel construction works for the high-speed railway in Kyoto and the national road in mountains. From these applications, factors for enhancing the permeability effect were confirmed, which includes the selection of high quality muck, insurance of the road-bed strength by the initial compaction, use of road drainage materials with high compressible property and permeability of filter, and intervals of drainage. 1 ref., 19 figs., 1 tab.

    For the state-run plant of Pakistan Steel in Pakistan, an investigational study was conducted on energy conservation and reduction in greenhouse effect gas emission. In the project, energy conservation technology on the following was tried to be introduced: coke oven coal moisture control (CMC) equipment, sintering cooler waste heat recovery equipment, blast furnace hot stove waste heat recovery equipment, blast furnace pulverized coal injection (PCI) equipment, blast furnace top pressure recovery turbine (TRT) equipment, and hot strip mill heating furnace regenerative type burner equipment. Further, in the project on environmental improvement, studies were made on coke oven environmental improvement and blast furnace cast house dust collection. The results of the study indicated that economical effects of the energy conservation project were considered as low because the unit price of energy of Pakistan Steel is low. However, substitution of the low-priced domestic coal for the imported coal has a good effect, and energy conservation in the TRT power generation and by the regenerative type burner produces a highly economical effect. Therefore, Pakistan Steel also agrees to positively promote the project. Moreover, concerning the environmental improvement project, it was considered that the necessity of the project is high in the relation of the coke oven aimed at reducing emissions of toxic substances.

    For global scale measures to be taken for environmental protection, it becomes more and more important in the future to positively transfer and spread energy conservation technologies of Japan to overseas countries. Especially, it is effective for both economic growth in the Asian region and global environmental protection to transfer technologies which the oil refining industry has been developing and accumulating. Energy conservation in the oil refining industry means the energy conservation by strengthening the operational control at the first and second oil crises in the first stage, the energy conservation in the second stage which was accompanied by small and medium scale plant/equipment investments during several years after the first stage, and the energy conservation in the third stage which was accompanied by large scale investments from the first half of the 1980s to the present, resulting in improvement of 40% over before the first oil crisis. As to environmental protection measures, measures to reduce waste from oil refinery against air pollution and water pollution were prepared by the first half of the 1970s, and technologies were established of waste water treatment, flue gas desulfurization and denitrification. A lot of facilities for improvement of product quality and for low pollution were installed. In addition to environmental technologies, also in other industries, there were seen the heightening of thermal efficiency of kiln and thermal efficiency of cooling technique of clinker cooler in the cement industry and the improvement of productivity in the paper/pulp industry. 360 figs., 62 tabs.

    Identification was intended on effects of such thermal factors as metabolic amount, environmental temperature and humidity, and clothing resistance on human body temperatures during works under hot environments. Therefore, measurements were carried out on human skin temperatures, rectum temperatures and humidity inside clothing, while amount of motion, environmental temperature, and clothing are changed in a constant temperature room and under a sun irradiation environment. Furthermore, a heat balance model was prepared, which divides the objects into an outer shell layer whose temperature changes depending on the result of this experiment and into a core having constant temperature characteristics. An equation to derive skin temperatures was introduced from the model. The equation formulated a calculation formula for heat accumulation in human body, which can be used as a hot heat index. Relationship between thermal factors and heat storage amount was investigated to consider a thermal limit for a physical work. An equation to derive skin temperatures was confirmed capable of expressing general change in skin temperatures, being proved by comparison with experiments. Calculation formulas for amount of heat stored in human body were shown capable of expressing influence of different thermal factors, the expression being useful as a hot heat index. Calculating the human body heat storage is very largely affected by effect of sweat to dissipate heat, hence it is necessary to improve the accuracy including that for body temperature adjusting reactions. 17 refs., 17 figs., 5 tabs.

    The Yoshino river is one of the most prominent rivers in Japan, representing the Shikoku district, with the trunk length of 194km and the basin of 3,750km{sup 2} extending in 4 prefectures in the district. The upstream area includes areas where the average annual rainfalls exceed 3,000mm, being famous as a high-rain zone. The basic water level stream is 24,000m{sup 3} s which is one of the largest in Japan. Schistosity develops with the Sambagawa metamorphic rocks, which tend to be easily weathered. As a result, there are many landslide spots distributed in the Sambagawa belt. The Shikoku district as a whole has one fifth of the landslide dangerous areas of Japan. Countermeasure activities against landslides were initiated in 1982 in Tokushima and Kochi prefectures. Outlines of landslides in those areas, underground structure, activity of landsliding, countermeasure activity against landslides, and the result of the activity are introduced. 12 figs.

    21.9km of the route between Doi and Iyosaijo of the Shikoku Jukan (Transverse) expressway was chosen along the central tectonic line which is the largest active fault in Japan. Countermeasure works for slope faces were carried out attaching importance to ground anchor and reinforced earth works, and the section was completed on March 29, 1991. In the section, longitudinal alignment, plain alignment and road structure were reexamined to determine the center line so as to avoid landslide areas as far as possible, and much cost curtailment was realized for the landslide countermeasure works although there were many slope face collapses during excavation. The collapsed soil amounted to about 50 to 600m{sup 3} for one collapsed spot, with 1 to 2m average thickness of the slid layers. Reinforced earth work method was found to be effective for small to medium scale slope face countermeasure works. PC anchor or other landslide countermeasure works were required for large scale landslides which have the depths of slide exceeding 2m. 5 refs., 7 figs.

    This paper describes the discussion report for fiscal 1998 on the CMG (coal methane gas) recovery and utilization project to be implemented from fiscal 1998 through fiscal 2002 at Tiefa Mining Bureau of Liaoning Province in China. The Daixing mine was selected as the survey object. The introduced technologies and facilities include test drilling for degassing (medium measure horizontal degassing of 300-m class), induction from degassing holes, fly ash sealing, sealed gas degassing, surveillance and control technologies and facilities. The recovered gas is to be supplied to the cities of Tiefa and Tieling as town gas, for which compressed gas feeding and controlling technologies and facilities will be introduced. This paper lists the gush-out quantity (1,000 Nm{sup 3}), the recovery quantity (1,000 Nm{sup 3}), the recovered gas concentration (%), the utilization quantity (1,000 Nm{sup 3}), and the utilization rate (%). The figures for the respective items before and after the implementation are 128366, 32949, 44.5, 7000, 5, 123500, 43890, 49.1, 39826, and 32. The quantity of gas gushing out at facings decreases in association with increase in the recovered gas quantity, whereas the gas concentration at facings in the Daixing mine in 2003 is estimated to decrease to 0.1%, contributing to safe mining operation. The test drilling for medium measure horizontal degassing expands the degassing assured scope per one test drilling seat, and can reduce the total test drilling length and construction amount.

    The present study has performed a two-dimensional sprint supporting experiment on effects imposed on vibration damping efficiency of spacers by variation in cable interval, vibration frequency, weight and diameter of parallel cables used in cable-stayed bridges. The experiment indicated phenomena varying in such a way that a characteristic having an unstable limit cycle is shown at cable intervals smaller than SH = 3.05 D, while a soft type characteristic is shown at cable intervals greater than 4.0 D. The onset velocity for wake galloping (WG) to appear increases in proportion to mass and attenuation parameters. Its increasing rate agrees nearly well with the manual type gradient. The appearance of WG can be suppressed easily when the cable intervals are greater than 4 D. The lower the cable vibration frequency, the higher the damping capability can be raised by using friction force. Because the damping performance of spacers decreases relatively when cable weight increases, the suppression effect decreases contrarily to a case of using no spacers. The wind velocity for the WG to appear when spacers are used can be evaluated by using the damping gradient. 5 refs., 20 figs., 1 tab.

    Abrupt and steep climate changes of the millennial scale as represented by the Dansgaard-Oeschger cycle (D-O cycle) and the behavior of the global surface layer system in their wake are outlined. The D-DO cycle is the abrupt and steep climate changes that are recorded in the Greenland continental ice sheet, and is grasped most typically as changes in the oxygen isotopic ratio in the ice. Studies reveal that the D-O cycle is a global episode that accompanied interaction between various subsystems constituting the global surface layer system. It is believed that in the D-O cycle there were changes not only in temperature but also in aridity/moisture and in the sea level, and probabilities are high that there was a great local variation in the way the changes took effect. The possibility has now become lower that the D-O cycle occurred in the interglacial epoch in the high latitude belt in the northern hemisphere, yet it remains likely that the climate changes driving the D-O cycle continued in the low latitude belt. 57 refs., 8 figs.

    For the study of CO{sub 2} absorption and fixation in the marine ecosystem, studies of coral reefs by RITE (Research Institute of Innovative Technology for the Earth) were subjected to discussion at the above-named workshops. It is after the elapse of a long geological time on the earth that CO2 in the atmosphere has arrived at the current level of concentration thanks to fixation and calcification by living organisms and to dissolution into the seawater. In the formation of CaCO{sub 3} that constitutes the coral skeleton, 1 mol Ca combines with 2 mol bicarbonates for the production of 1 mol CaCO{sub 3} and 1 mol CO{sub 2}. The reaction may suggests a consequential increase of CO2 in the atmosphere but such CO{sub 2} is in reality consumed by being converted into organic substances in a photosynthetic process performed by symbiotic algae. Calculation was made for the whole of Bora Bay, Miyakojima Island, and the result was that 700kg-C/day comes to be stored in the form of organic matters in the community of coral reef organisms. In a coral reef, even when it emits CO2 into the atmosphere, there is organic matter production which exceeds the lost CO{sub 2}. Coral reefs fix carbon out of the seawater at the rate of 0.42Gt-C/year, which is the aggregate of 0.3Gt organic matters and 0.12Gt CaCO{sub 3}. (NEDO)

    The aim is to develop a technology for detecting environmental pollution before it becomes apparent and thereby to contribute to the development of technologies to minimize the damage that may be inflicted upon the global environment. For this purpose, researches are conducted in search of techniques to detect, at high speed with high sensitivity over a wide scope, the response of living organisms to chemicals. In a research on the application of the reaction of ecosystem to environmental stress, communication between living organisms in coping with environmental chemicals is investigated. It is then found that the growth of vegetable roots may be used as a measure for the detection of environmental pollutants but that the method is too low in sensitivity. A research is conducted on the creation of an ecological reporter function using the biological amplification technique. It is then found that the immunoreaction-aided measuring of environmental pollutants yields an excellent result in terms of sensitivity but that it has a problem in its resistance to environmental conditions. In a research on the standardization of environmental measurements using ecological information, it is found that the primary object of research and development should be a systematization technology compatible with biological functions.

    The research vessel Chikyu is expanding new frontiers in science, technology, and international collaboration through deep-sea expedition. The Chikyu (length: 210 m, gross tonnage: 56752 tons) has advanced and comprehensive scientific research facilities. One of the scientific purposes of the vessel is to investigate into unexplored biosphere (i.e., undescribed extremophiles) on the Earth. Therefore, "the onboard laboratory" provides us systematic microbiological protocols with a physical containment situation. In parallel, the onboard equipments provide sufficient space for fifty scientists and technical support staff. The helicopter deck also supports various logistics through transporting by a large scale helicopter (See, http://www.jamstec.go.jp/chikyu/eng/). Since the establishment of Panel on Planetary Protection (PPP) in Committee on Space Research (COSPAR), we have an international consensus about the development and promulgation of planetary protection knowledge, policy, and plans to prevent the harmful effects of biological contamination on the Earth (e.g., Rummel, 2002). However, the matter to select a candidate location of initial quarantine at BSL4 level is often problematic. To answer the key issue, we suggest that international waters can be a meaningful option with several advantages to conduct initial onboard-biological quarantine investigation. Hence, the research vessel Chikyu is promising for further PPP requirements (e.g., Enceladus sample return project: Tsou et al., 2012).

    For the purpose of conserving energy and reducing greenhouse effect gas, a remodeling project was studied of urea plants constructed from the 1960s to the 1970s. Conditions for being companies for study are as follows: company has a production scale of more than 0.2 million t/y, adopts the complete circulation method, and will continue operation. And, Duncans Industries Ltd. (DIL) was selected. DIL owns the ammonia plant of 3 series x 400 t/d and the urea plant of 3 series x 682 t/d. In the modeling, stripper and carbamate condenser are added to the existing reactor as the main equipment. As a result of the study, the energy conservation effect was 13,667 toe/y, and the amount of reduction in greenhouse effect gas was 42,289 t-CO2/y. The total amount of this project was roughly estimated at 1.517 billion yen. By carrying out the project, the urea production cost is reduced approximately $9/t, but the project becomes unprofitable if the urea price is based on $188.1/t. (NEDO)

    The coal utilization is expected to make substantial growth according to the long-term energy supply/demand plan. To further expand the future coal utilization, however, it is indispensable to reduce environmental loads in its total use with other energies, based on the coal use. In this survey, a regional model survey was conducted as environmental load reduction measures using highly cleaned coal which were taken in fiscal 1993 and 1994. Concretely, a model system was assumed which combined facilities for mixed combustion with coal and other energy (hull, bagasse, waste, etc.) and facilities for effective use of burned ash, and potential reduction in environmental loads of the model system was studied. The technology of mixed combustion between coal and other energy is still in a developmental stage with no novelties in the country. Therefore, the mixed combustion technology between coal and other energy is an important field which is very useful for the future energy supply/demand and environmental issues. 34 refs., 27 figs., 48 tabs.

    Oil demand is expected to substantially grow in the future, and the use of oil with combustibles such as hull, baggase and waste is considered from an effective use of energy. A regional model survey was conducted as measures to reduce environmental loads where the fuel mixing combustion with coal and other energy is made the core. The domestic production amount of hull is 2.4-3.0 tons/year, which have a heating value of 3,500 kcal/kg. If hull can be formed into the one storable for a the long term (the one mixed with low grade coal, etc.), it can be a fuel for stable supply. Bagasse is produced 100 million tons/year, which have a heating value of 2,500 kcal/kg. Among wastes, waste tire, plastics, waste, sludge, etc. have a lot of problems in terms of price and environment, but each of them has a heating value during 3,000-10,000 kcal/kg. As to the coal combustion, the pollutional regulation on it is strict, and much higher processing technology is needed. The technology of coal fuel mixing combustion with other energy has not risen higher than the developmental level. Though the technology is a little bit higher in price than the coal fuel single combustion, it is viable. 38 refs., 32 figs., 65 tabs.

    As the element research on a 10-MW class geothermal binary cycle power plant to be built in the coming term, researches were made on corrosion preventive measures and the cycle optimum for the plant. This paper reports the achievements in fiscal 1982. In the research on corrosion preventive measures, different kinds of materials were buried in three locations having different soil natures to study corrosion due to soil. The corrosion rate of heat conducting pipes using the heat media R114 was estimated as very small as 1/40 of the corrosion rate in geothermal waters. In the research on the cycle optimum for the plant, experimental research was performed on thermo-dynamic properties and thermal stability of the mixed media using R114 as the main component. As a result, the R114/R112 system was found to have higher pressure than R114, but the media circulation amount is less, and the output at the power transmission terminal increased by 5 to 10%. The system showed the most excellent heat cycle characteristics. In the research of building a power plant installed with two different power generation systems, a computer program was prepared that calculates heat balances all at once for the case of installing a geothermal binary cycle power plant in a geothermal steam power plant.

    Research is conducted to properly deal with environmental problems, such as compromised solar cell safety, which may follow the mass introduction and diffusion of photovoltaic power systems. In the research of fiscal 1999 on technical literature on environmental measures against lead and animal tests, a need was found to reduce lead in power systems and to grasp lead elution characteristics for the establishment of environmental measures. In a safety test conducted for thin-film CIS (copper indium diselenide) based solar cells, basic data were collected about the vaporization rate of Se, the effect of moisture on the Se vaporization rate, etc. Basic data were also collected about the relationship between the combustion temperature and the amount of scattered lead in particular from the solder used as the conducting material in silicon based solar cells. In the evaluation of the environmental impact of thin-film CIS solar cells in case of fire, it was found that Se concentration below 10-20m in the plume was near the permissible concentration of 0.1mg/m{sup 3} as recommended by Japan Society for Occupational Health and that the concentration levels predicted for the periphery were two orders of magnitude smaller than the mandatory level.

It is treating raw coal from 10 coal mines for classification and preparation, and shipping coal of various types that meet the standards for domestic use and export. The survey results point out that unrecovered coal remains in waste water discharged from the coal preparation plants to pollute the sea area, and that quantity of the refuse increases because of the unrecovered coal it contains. The environmental technologies needed to introduce include modification to variable wave pattern type jigging separator, refuse height measuring instrument and automatic controller, circulating heavy medium gravimeter, highly functional settling pond, and flocculent facilities.

    A lathe, which is a central tool in a factory of automobiles or home electric appliances, tends to suffer decreased machining precision resulting from thermal deformation. This project is aimed at development of the energy-saving, high-precision lathe technologies using self compulsory cooling and thermal insensitive technologies as the countermeasures against the thermal deformation. The self compulsory cooling is a method of cooling by evaporation of water with an evaporative, water-absorptive cloth being bonded to a machine tool surface around the major axis. The thermal insensitive technologies include the three-dimensionally zero-center design technologies which help design a lathe in such a way to set the processing point (tool working point) at the base of thermal deformation in the X, Y and Z axis directions; material combination technologies to control thermal deformation; and coloring technologies to control thermal deformation. The development target is the high-precision lathe fabrication technologies, which realize a temporal precision change of 1 to 2 {mu}m or less per work dimension of 100mm. The activities cover 5 areas, including development of elementary technologies for each item and construction/evaluation of the full-size test unit. (NEDO)

    D/V Chikyu implemented by CDEX/JAMSTEC joined IODP from 2007. Various LWD (Logging While Drilling) and wireline logging have been carried out in many expeditions and for various purposes. Significant features of logging in Chikyu expeditions are many use of LWD than wireline logging, and riser dirlling. riser selected specific tools for each scientific target, and 3) carried out various borehole experiments. LWD has been more popular than wireline logging in Chikyu expeditions, because its advantages match theirs science targets. The advantages are followings. 1) LWD has more opportunities for measurement in unstable borehole, such as in the series of Nankai trough drilling expeditions. 2) LWD realtime data allows us to make realtime interpretation and operational decision. Realtime interpretation was required to set obsevartory at the properposition. 3) LWD before coring allows us to make a strategy of spot coring.We can design coring intervals for our interest and core length to improve core recovery.Riser drilling brings us merits for logging. One is hole stability (good hole condition) and the other is the use of large diameter tools. Controled drilling mud in riser drilling system prevent mud invasion to formation and mitigates collapse of borehole wall. They reduce the risk of tool stack and improve data quality. Large diameter of riser pipe enhances variation of tool seizes. A couple of new tools were used for new measurement and improvement of the data quality. For example, SonicScanner (trademark of Schulumberger) successfully measured compressional and share velocity in very low velocities at the soft sediment, where it has been difficult to measure them with conventional DSI tool (Exp319). The stress and pore pressure in the borehole were measured with the wireline logging tool, (Schlumberger MDT). The single probe tool enable to measure temporal formation fluid pressure. The double packer tool enable to fracture test by sealing and pumping in the

    The Oman Drilling Project provides an unprecedented opportunity to study the formation and alteration of oceanic crust and peridotite. Key to answering the main questions of the project are a characterization of the primary and secondary minerals present within the drill core and their spatial relationships. To that end, we used the Caltech imaging spectrometer system to scan the entire 1.5-km archive half of the core from all four gabbro and listvenite boreholes (GT1A, GT2A, GT3A, and BT1B) at 250 µm/pixel aboard the JAMSTEC Drilling Vessel Chikyu during the ChikyuOman core description campaign. The instrument measures the visible and shortwave infrared reflectance spectra of the rocks as a function of wavelength from 0.4 to 2.6 µm. This wavelength range is sensitive to many mineral groups, including hydrated minerals (phyllosilicates, zeolites, amorphous silica polytypes), carbonates, sulfates, and transition metals, most commonly iron-bearing mineralogies. To complete the measurements, the core was illuminated with a halogen light source and moved below the spectrometer at 1 cm/s by the Chikyu's Geotek track. Data are corrected and processed to reflectance using measurements of dark current and a spectralon calibration panel. The data provide a unique view of the mineralogy at high spatial resolution. Analysis of the images for complete downhole trends is ongoing. Thus far, a variety of minerals have been identified within their petrologic contexts, including but not limited to magnesite, dolomite, calcite, quartz (through an Si-OH absorption due to minor H2O), serpentine, chlorite, epidote, zeolites, mica (fuchsite), kaolinite, prehnite, gypsum, amphibole, and iron oxides. Further analysis will likely identify more minerals. Results include rapidly distinguishing the cations present within carbonate minerals and identifying minerals of volumetrically-low abundance within the matrix and veins of core samples. This technique, for example, accurately identifies

    The transition from the base of the Oman ophiolite to the underlying metamorphic sole was drilled at Hole BT1B (Sumail Massif) during Phase 1 of Oman Drilling Project (Winter 2016-2017). 74 samples were collected from the 300m of recovered cores for whole rock geochemical and XRD analyses. 55 listvenites, ophicarbonates and serpentinites, and 19 schists and greenstones were analyzed for major and minor elements (XRF) and for CO2 and S concentrations (CHNS) aboard DV Chikyu (ChikyuOman, Summer 2017). Analyses for trace elements (ICP-MS) at the University of Montpellier are in progress. The composition of listvenites, ophicalcites and serpentinites recovered at Hole BT1B record extensive interactions between CO2-rich fluids and the serpentinized peridotites. These reactions involved addition of SiO2 and formation of carbonates at the expense of the serpentinized peridotite protolith. All samples recovered from the mantle section are enriched in fluid mobile and incompatible trace elements compared to the mean composition of the Oman mantle. These enrichments are up to 103 times the Oman mantle for Rb and Ba. They mimic the pattern of the samples from the metamorphic sole. This suggests that the composition of the listvenites in these elements is controlled by that of contaminating fluids that may have originated in the same lithologies as those drilled at the base of Hole BT1B. Listvenites, ophicalcites and serpentinites also show notable downhole chemical variations, with listvenites showing marked variations in Al2O3 and TiO2. Occurrence of lherzolites and cpx-harzburgites has been reported at the base of the Oman dominantly harzburgitic mantle section. The observed variations in the listvenites (Al2O3 and TiO2) could be related to the composition of their protolith, the deepest having more fertile compositions. Alternatively, the observed downhole changes in the composition of listvenites may relate to the progressive equilibration of the reacting ultramafic

    Hole GT1A (22° 53.535'N, 58° 30.904'E) was drilled by the Oman Drilling Project (OmDP) into GT1A of the Samail ophiolite, Oman. OmDP is an international collaboration supported by the International Continental Scientific Drilling Program, the Deep Carbon Observatory, NSF, IODP, JAMSTEC, and the European, Japanese, German and Swiss Science Foundations, with in-kind support in Oman from the Ministry of Regional Municipalities and Water Resources, Public Authority of Mining, Sultan Qaboos University, and the German University of Technology. Hole GT1A was diamond cored in 22 Jan to 08 Feb 2017 to a total depth of 403.05 m. The outer surfaces of the cores were imaged and described on site before being curated, boxed and shipped to the IODP drill ship Chikyu, where they underwent comprehensive visual and instrumental analysis. Hole GT1A drilled the lower crustal section in the southern Oman Ophiolite and recovered 401.52 m of total cores (99.6% recovery). The main lithology is dominated by olivine gabbro (65.9%), followed in abundance by olivine-bearing gabbro (21.5%) and olivine melagabbro (3.9%). Minor rock types are orthopyroxene-bearing olivine gabbro (2.4%), oxide-bearing olivine gabbro (1.5%), gabbro (1.1%), anorthositic gabbro (1%), troctolitic gabbro (0.8%); orthopyroxene-bearing gabbro (0.5%), gabbronorite (0.3%); and dunite (0.3%). These rocks are divided into Lithologic Unit I to VII at 26.62 m, 88.16 m, 104.72 m, 154.04 m, 215.22 m, 306.94 m in Chikyu Curated Depth in descending order; Unit I and II consist of medium-grained olivine gabbro with lower olivine abundance in Unit II. Unit III is medium-grained olivine melagabbros, marked by an increase in olivine. Unit IV is relatively homogenous medium-grained olivine gabbros with granular textures. Unit V is identified by the appearance of fine-grained gabbros, but the major rocktypes are medium grained olivine gabbros. Unit VI is medium-grained olivine gabbro, marked by appearance of orthopyroxene. Unit VII

    Hole BT1B (23°21.861' N, 58°10.957' E) was drilled by the Oman Drilling Project (OmDP) on the north side of Wadi Mansah in the Samail ophiolite, Oman. OmDP is an international collaboration supported by the International Continental Scientific Drilling Program, Deep Carbon Observatory, NSF, IODP, JAMSTEC, and the European, Japanese, German and Swiss Science Foundations, with in-kind support in Oman from the Ministry of Regional Municipalities and Water Resources, Public Authority of Mining, Sultan Qaboos University, and the German University of Technology. Hole BT1B was cored from 6 to 23 March 2017, to a depth of 300.05 m. The outer surfaces of the cores were imaged and described onsite before being curated, boxed and shipped to the IODP drill ship Chikyu. Hole BT1B sampled carbonated peridotite (listvenite), 2 carbonate-veined serpentinite bands at 80-100 and 180-185 m depth, a few cm of ultracataclasite and 70 cm of fault gouge at 197 m depth, followed by 103 m metamorphic sole. Onboard Chikyu, BT1B underwent X-ray computed tomography (CT) and multi-sensor logging, imaging and spectroscopy, macroscopic and thin section observations, physical properties measurements, and XRF, XRD and ICP-MS analyses. 1st authors of abstracts reporting initial results are Beinlich (matrix characteristics), de Obeso (modeling mass transfer), Godard (XRF and ICP-MS whole rock data), Greenberger (infrared spectroscopy), Johnson (XRF core scanner), Kelemen (overall petrology), Manning (veins), and Michibayashi (X-ray CT). Listvenite is composed of carbonate + quartz + Fe-oxyhydroxides, + minor relict spinel ± chromian mica (fuchsite). The mineralogy suggests formation at < 150°C. The bulk rock density is similar to that of gabbro but the P-wave velocity is generally higher. Rock textures suggest viscous deformation, while additional brittle deformation is recorded by older veins and younger breccias and faults. The metamorphic sole consists of fine-grained to microcrystalline

    IODP has extensively used the D/V Chikyu to drill the Kumano portion of the Nankai Trough, including two well sites within the Kumano Basin. IODP Expeditions 338 and 348 drilled deep into the inner accretionary prism south of the Kii Peninsula collecting a suite of LWD data, including natural gamma ray, electrical resistivity logs and borehole images, suitable to characterize structures (fractures and faults) inside the accretionary prism. Structural interpretation and analysis of logging-while-drilling data in the deep inner prism revealed intense deformation of a generally homogenous lithology characterized by bedding that dips steeply (60-90°) to the NW, intersected by faults and fractures. Multiple phases of deformation are characterized. IODP Expedition borehole images and LWD data acquired in the last decade in previous and results of NantroSEIZE IODP Expeditions (314, 319) were also analyzed to investigate the internal geometries and structures of the Nankai Trough accretionary prism. This study focused mainly on the characterization of the different types of structures and their specific position within the accretionary prism structures. New structural constraints and methodologies as well as a new approach to the characterization of study of active structures inside the prism will be presented.

    Full Text Available The IODP Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE will, for the fi rst time ever, attempt to drill into, sample, and instrument the seismogenic portion of a plate-boundary fault or megathrust within a subduction zone. Access to the interior of active faults where in situ processes can be monitored and fresh fault zone materials can be sampled is of fundamental importance to the understanding of earthquake mechanics. As the December 2004 Sumatraearthquake and Indian Ocean tsunami so tragically demonstrated,large subduction earthquakes represent one of the greatest natural hazards on the planet. Accordingly, drilling into and instrumenting an active interplate seismogenic zone is a very high priority in the IODP Initial Science Plan (2001. Through a decade-long series of national and international workshops, a consensus emerged that the Nankai Trough is an ideal place to attempt drilling and monitoring of the seismogenic plate interface. The fi rst phase of NanTroSEIZE drilling operations has now been scheduled for the late summer of 2007. It involves parallel deployment of both the new U.S. Scientifi c Ocean Drilling Vessel (SODV, this volume and the riser drilling vessel Chikyu.

    A scientific drilling expedition, CK16-01 was conducted by D/V Chikyu in an active hydrothermal field on the Iheya-North Knoll in Okinawa Trough in February-March, 2016 as a part of "Next-generation Technology for Ocean Resources Survey" of the Cross-ministerial Strategic Innovation Promotion Program (SIP). During the expedition logging while drilling (LWD) was deployed to uncover the architecture of modern hydrothermal deposits near the seafloor. A downhole sequence of fracture network (stock-work) was discovered by high resolution resistivity images at Site C9023 in the southern part of the knoll. More than 500 structural features were extracted from the borehole images down to 188 meter below the seafloor. Quantitative image analyses were performed and three types of conductive fractures were identified and classified as Generation 1 (G1), Generation 2 (G2), and Generation 3 (G3) based on the crossing or cutting relationship. The average thickness of fractures decrease with generation from G1 (78 mm), G2 (57 mm), to G3 (45 mm). G1 is developed in the entire interval, whereas G2 and G3 are commonly observed in the intervals of lower gamma ray and high resistivity ( 10 ohm-m) at 77-125 m and 167-186 m where sulfide minerals hosted in silicified rocks were observed in recovered core samples. Low angle fractures (<30°) are typically developed in the interval at 120 -125 m, suggesting possible lateral hydrothermal conduits. The quantitative analysis of fracture network based on borehole images shows the detailed formation process of stock-work in the basal part of modern hydrothermal system.

    The Pacific plate is surrounded by circum-Pacific active margin, along which volcanic and seismic activities are very high. Ultra-Mega-Earthquakes (=UMEs, M>9.0) are occasionally observed along the margin, where sedimentary rocks of subducting slaves contact with the accreted sedimentary rocks of subducted slaves. But, those UME have never been occured along western Pacific islandarc-trench system including Izu-Ogasawara (=Bonin)-Mariana-Yap-Palau-Philippine-Tonga-Kermadec Trenches. I assume that the geological and petrological characteristics of the subduction boundaries are very important to understand those different seismic activities. Along the above mentioned trench inner wall, especially in the southern Mariana, mantle peridotites are widely distributed. Subducting slave contacts directly with the olivine dominant mantle peridotites of subducted slave, serpentinite layer can be deposited easily under hydrous oceanic sub-bottom environment and very slippery subduction boundaries are left along the subduction zone.On the other hand, those geological evidences give us some ideas on how to avoid UMEs in the Japanese Islands along Japan Trench and Nankai Trough in future. We will be able to change artificially from normal subduction boundaries with asperity zone into slippery subduction boundaries with serpentine layer, by means of serpentine mud injection toward the subduction boundaries interior by combining the following improved drilling technologies A and B. (A) Deep Sea Drilling Vessel CHIKYU has a drilling ability to reach subduction boundary with asperity zone in the Nankai Trough. (B) Advanced drilling technology in the shale gas industry is tremendous, that is, after one vertical deep drilling, horizontal drilling towards several direction are performed, then shale gas is collected by hydraulic fracturing method. I hope that, after several generations, our posterity will be able to avoid UMEs by continuous serpentine mud injection.

    Full Text Available Scientific ocean drilling’s first in situ stress measurement was made at Site C0009A during Integrated Ocean Drilling Program (IODP Expedition 319 as part of Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE Stage 2. The Modular Formation Dynamics Tester (MDT, Schlumbergerwireline logging tool was deployed in riser Hole C0009A to measure in situ formation pore pressure, formation permeability (often reported as mobility=permeability/viscosity, and the least principal stress (S3 at several isolated depths (Saffer et al., 2009; Expedition 319 Scientists, 2010. The importance of in situ stress measurements is not only for scientific interests in active tectonic drilling, but also for geomechanical and well bore stability analyses. Certain in situ tools were not previously available for scientific ocean drilling due to the borehole diameter and open hole limits of riserless drilling. The riser-capable drillship, D/V Chikyu,now in service for IODP expeditions, allows all of the techniques available to estimate the magnitudes and orientations of 3-D stresses to be used. These techniques include downhole density logging for vertical stress, breakout and caliper log analyses for maximum horizontal stress, core-based anelastic strain recovery (ASR, used in the NanTroSEIZE expeditions in 2007–2008, and leak-off test (Lin et al., 2008 and minifrac/hydraulic fracturing (NanTroSEIZE Expedition319 in 2009. In this report, the whole operational planning process related to in situ measurements is reviewed, and lessons learned from Expedition 319 are summarized for efficient planning and testing in the future.

    Deep subseafloor environments associated with hydrocarbon reservoirs have been least explored by previous scientific drilling and hence the nature of deep subseafloor life and its ecological roles in the carbon cycle remain largely unknown. In this study, we performed cultivation of subseafloor methanogenic communities using a continuous-flow bioreactor with polyurethane sponges, called down-flow hanging sponge (DHS) reactor. The sample used for the reactor cultivation was obtained from 2 km-deep coalbeds off the Shimokita Peninsula of Japan, the northwestern Pacific, during the Integrated Ocean Drilling Program (IODP) Expedition 337 using a riser drilling technology of the drilling vessel Chikyu. The coalbed samples were incubated anaerobically in the DHS reactor at the in-situ temperature of 40°C. Synthetic seawater supplemented with a tiny amount of yeast extract, acetate, propionate and butyrate was provided into the DHS reactor. After 34 days of the bioreactor operation, a small production of methane was observed. The methane concentration was gradually increased and the stable carbon isotopic composition of methane was consistency 13C-depleted during the bioreactor operation, indicating the occurrence of microbial methanogenesis. Microscopic observation showed that the enrichment culture contained a variety of microorganisms, including methanogen-like rod-shaped cells with F420 auto-fluorescence. Interestingly, many spore-like particles were observed in the bioreactor enrichment. Phylogenetic analysis of 16S rRNA genes showed the growth of phylogenetically diverse bacteria and archaea in the DHS reactor. Predominant archaeal components were closely related to hydrogenotrophic methanogens within the genus Methanobacterium. Some predominant bacteria were related to the spore-formers within the class Clostridia, which are overall in good agreement with microscopic observations. By analyzing ion images using a nano-scale secondary ion mass spectrometry (Nano

    A scientific drilling expedition was conducted at an active hydrothermal field on the Iheya-North Knoll by D/V Chikyu in 2014 (Expedition 907) as a part of "Next-generation Technology for Ocean Resources Survey" of the Cross-ministerial Strategic Innovation Promotion Program. During the expedition logging while drilling (LWD) was deployed to constrain the area of the fluid reservoir beneath seafloor followed by three coring holes down to 150 meter below the seafloor (mbsf). The LWD system is composed of arcVISION for resistivity and natural gamma ray measurement and TeleScope for real-time transmission of drilling parameters and arcVISION data. Five sites (C9011-15) at the Iheya-North Original Site and one site (C9016) at Aki Site were drilled with LWD. At C9012 and C9016, the arcVISION detected temperature anomaly up to 84℃ at 234 mbsf and up to 39℃ at 80 mbsf, respectively. The temperature quickly increases at that depth and it would reflect the existence of high-temperature heat source along borehole. Due to the continuous fluid circulation during drilling, the measured temperature does not indicate in-situ temperature, but it reflects the heat disturbed by the cold circulated water instead. High quality resistivity and natural gamma ray data were acquired at six sites. The log curves at Site C9016 show characteristic response; the natural gamma ray log exhibits extremely high radiation (>500 gAPI) at 7-13 and 23-31 mbsf (Zone A). In the underlying interval of 31-40 mbsf, the resistivity log exhibits extremely low value (LWD-based lithological interpretation was confirmed by the following core description. Zones A and B can be correlated to altered clay zone and sulfide zone including sphalerite, galena, chalcopyrite, and pyrite. Our results show that LWD is a powerful tool for the identification and characterization of submarine hydrothermal deposits and LWD survey enhances the successful recovery of sulfide samples.

    Mud logging, a tool in riser drilling, makes use of the essentially "closed-circuit" drilling mud flow between the drilling platform downhole to the bit and then back to the platform for analyses of gas from the formation in the drilling mud, cuttings from downhole, and a range of safety and operational parameters to monitor downhole drilling conditions. Scientific riser drilling, with coincident control over drilling mud, downhole pressure, and returning drilling mud analyses, has now been in use aboard the scientific riser drilling vessel Chikyu since 2009. International Ocean Discovery Program (IODP) Expedition 348, as part of the goal of reaching the plate boundary fault system near ~5000 mbsf, has now extended the deep riser hole (Hole C0002 N & P) to 3058.5 mbsf. The mud gas data discussed here are from two approximately parallel boreholes, one a kick-off from the other; 860-2329 mbsf (Hole C0002N) and 2163-3058 mbsf (Hole C0002P). An approximate overlap of 166 m between the holes allows for some slight depth comparison between the two holes. An additional 55 m overlap at the top of Hole C0002P exists where a 10-5/8-inch hole was cored, and then opened to 12-1/4-inch with logging while drilling (LWD) tools (Fig. 1). There are several fault zones revealed by LWD data, confirmed in one instance by coring. One of the defining formation characteristics of Holes C0002 N/P are the strongly dipping bedding planes, typically exceeding 60º. These fault zones and bedding planes can influence the methane/ethane concentrations found in the returning drilling mud. A focused comparison of free gas in drilling mud between one interval in Hole C0002 P, drilled first with a 10 5/8-inch coring bit and again with an 12 ¼-inch logging while drilling (LWD) bit is shown. Hole C0002N above this was cased all the way from the sea floor to the kick-off section. A fault interval (in pink) was identified from the recovered core section and from LWD resistivity and gamma.

    Hole GT3A (23.11409 N, 58.21172 E) was drilled by the Oman Drilling Project (OmDP) into Wadi Abdah of the Samail ophiolite, Oman. OmDP is an international collaboration supported by the International Continental Scientifi1c Drilling Program, the Deep Carbon Observatory, NSF, IODP, JAMSTEC, and the European, Japanese, German and Swiss Science Foundations, with in-kind support in Oman from the Ministry of Regional Municipalities and Water Resources, Public Authority of Mining, Sultan Qaboos University, and the German University of Technology. Hole GT3A was diamond cored in February to March 2017 to a total depth of 400 m. The outer surfaces of the cores were imaged and described on site before being curated, boxed and shipped to the IODP drill ship Chikyu, where they underwent comprehensive visual and instrumental analysis. Hole GT3A recovered predominantly sheeted dikes and gabbros and has been sub-divided into 4 igneous groups based on the abundance of gabbro downhole. Group 1 (Upper Sheeted Dike Sequence) occurs from 0 to 111.02 m, group II (Upper Gabbro Sequence) is from 111.02 to 127.89 m, group III (Lower Sheeted Dike Sequence) is between 127.89 to 233.84 m and group IV (Lower Gabbro Sequence) is from 233.84 to 400 m. Group II and IV are both associated with almost equal proportions of dikes to gabbroic lithologies, whereas group I & III have >95% dikes. The sheeted dikes were logged as either basalt (46.9 %) or diabase (26.2 %) depending on the predominant grain size of the dike. Gabbroic lithologies include (most to least abundant) gabbro, oxide gabbro and olivine gabbro. Other lithologies present include diorite (7.5%) and tonalite and trondhjemite (1%). Tonalite and trondhjemite are present as cm-sized dikelets and are found within group II and IV. Gabbroic lithologies generally display a varitextured appearance and are characterised by the co-existence of poikilitic and granular domains. Detailed observations of chilled margins and igneous contacts reveal

    The middle Okinawa Trough, located along the Ryukyu- arc on the margin of the East China Sea, has several active hydrothermal fields. From February to March 2016, Cruise CK16-01 by D/V Chikyu targeted the Iheya-North Knoll and southern flank of the Iheya Minor Ridge to comprehend sub-seafloor geological structure and polymetallic sulfide mineralization. In this cruise, we installed two Kuroko cultivation apparatuses equipped with P/T sensors, flowmeter and load cell to monitor pressure, temperature and flow rate of hydrothermal fluid discharged from the artificial hydrothermal vent together with weight of hydrothermal precipitate. During Cruise KR16-17 in January 2017, two cultivation cells with sensor loggers were successfully recovered by ROV Kaiko MK-IV and R/V Kairei. We report these physical sensor data obtained by more than 10 months monitoring at two deep-sea artificial hydrothermal vents through many first and challenging operations.Hole C9017B at southern flank of the Iheya Minor Ridge (water depth of 1,500 mbsl), fluid temperature was constant ca. 75 ºC for 5 months from the beginning of monitoring. Then temperature gradually decrease to be 40 ºC. In November 2016, temperature and pressure suddenly dropped and quickly recovered due to the disturbance of subseafloor hydrology, induced by another drilling operation at Hole C9017A which is 10.8 meters northeastward from Hole C9017B during Cruise CK16-05. Temperature data exhibit conspicuous periodic 12.4hour cycles and this is attributable to oceanic tidal response. The amplitude of temperature variations increased along with decline of the temperature variations increased along with decline of the temperature. The average flow rate was 67 L/min for 9 hours from the onset of monitoring.Hole C9024A at the Iheya-North Knoll (water depth of 1,050 msl), the maximum temperature reached 308 ºC, which is similar to the maximum value of 311 ºC obtained from the ROV thermometer. The average flow rate was 289 L

    Integrated Ocean Drilling Program Expedition 338 was the second scientific expedition with D/V Chikyu during which riser drilling was conducted as part of the Nankai Trough Seismogenic Zone Experiment. Riser drilling enabled sampling and real-time monitoring of drilling mud gas with an onboard scientific drilling mud gas monitoring system ("SciGas"). A second, independent system was provided by Geoservices, a commercial mud logging service. Both systems allowed the determination of (non-) hydrocarbon gas, while the SciGas system also monitored the methane carbon isotope ratio (δ(13)CCH4). The hydrocarbon gas composition was predominated by methane (> 1%), while ethane and propane were up to two orders of magnitude lower. δ(13)CCH4 values suggested an onset of thermogenic gas not earlier than 1600 meter below seafloor. This study aims on evaluating the onboard data and subsequent geological interpretations by conducting shorebased analyses of drilling mud gas samples. During shipboard monitoring of drilling mud gas the SciGas and Geoservices systems recorded up to 8.64% and 16.4% methane, respectively. Ethane and propane concentrations reached up to 0.03 and 0.013%, respectively, in the SciGas system, but 0.09% and 0.23% in the Geoservices data. Shorebased analyses of discrete samples by gas chromatography showed a gas composition with ~0.01 to 1.04% methane, 2 - 18 ppmv ethane, and 2 - 4 ppmv propane. Quadruple mass spectrometry yielded similar results for methane (0.04 to 4.98%). With δD values between -171‰ and -164‰, the stable hydrogen isotopic composition of methane showed little downhole variability. Although the two independent mud gas monitoring systems and shorebased analysis of discrete gas sample yielded different absolute concentrations they all agree well with respect to downhole variations of hydrocarbon gases. The data point to predominantly biogenic methane sources but suggest some contribution from thermogenic sources at depth, probably due

    From 16th November to 15th December 2016, D/V Chikyu drilled the sea bottom around hydrothermal fields at HAKUREI site in the Izena Hole, Okinawa Trough. Site C9025, C9026, C9027, C9028, and C9032 are located along the transect line from the top of the northern mound of HAKUREI site to the eastward, and Site C9030 for the control site is located about 500 m northwest of the mound. Mg concentrations have generally been used to estimate mixing ratios between hydrothermal end-member and seawater in samples from hydrothermal vents. Higher Mg concentrations, however, were detected in the interstitial water than that of seawater, which could be due to artificially dissolution of Mg-bearing minerals that had formed in in-situ environments, when the cored sediments had become cool after their recovery on ship. Similar features were observed with regard to sulfate concentrations, and it suggests that these chemical species are not suitable to estimate quantitatively the contribution of hydrothermally-derived components. In some layers, chloride concentrations were different from that of seawater, indicating that hydrothermal fluids that had been suffered from phase separation flowed into the layers. The deviation, however, was positive or negative relative to that of seawater for an influence of brine or vapor phase, respectively. Therefore chloride concentrations are also not suitable to evaluate a quantitative contribution of hydrothermal end-member. On the other hand, K and B showed only enrichments relative to the seawater, and their highest concentrations are consistent with the reported hydrothermal end-members of each species at HAKUREI site. Using the concentrations of K and B can be evaluated for an influence of hydrothermal components. Furthermore, the headspace gas data are useful in the layers of sulfide minerals and silicified rocks, even though the interstitial waters could not be obtained because of their hardness. Based on these indices, hydrothermal fluids

    Since the first deep biosphere-dedicated Ocean Drilling Program (ODP) Leg 201 using the US drill ship JOIDES Resolution in 2002, scientific ocean drilling has offered unique opportunities to expand our knowledge of the nature and extent of the deep biosphere. The latest estimate of the global subseafloor microbial biomass is ~1029cells, accounting for 4 Gt of carbon and ~1% of the Earth's total living biomass. The subseafloor microbial communities are evolutionarily diverse and their metabolic rates are extraordinarily slow. Nevertheless, accumulating activity most likely plays a significant role in elemental cycles over geological time. In 2010, during Integrated Ocean Drilling Program (IODP) Expedition 329, the JOIDES Resolutionexplored the deep biosphere in the open-ocean South Pacific Gyre—the largest oligotrophic province on our planet. During Expedition 329, relatively high concentrations of dissolved oxygen and significantly low biomass of microbial populations were observed in the entire sediment column, indicating that (i) there is no limit to life in open-ocean sediment and (ii) a significant amount of oxygen reaches through the sediment to the upper oceanic crust. This "deep aerobic biosphere" inhabits the sediment throughout up to ~37 percent of the world's oceans. The remaining ~63 percent of the oceans is comprised of higher productivity areas that contain the "deep anaerobic biosphere". In 2012, during IODP Expedition 337, the Japanese drill ship Chikyu explored coal-bearing sediments down to 2,466 meters below the seafloor off the Shimokita Peninsula, Japan. Geochemical and microbiological analyses consistently showed the occurrence of methane-producing communities associated with the coal beds. Cell concentrations in deep sediments were notably lower than those expected from the global regression line, implying that the bottom of the deep biosphere is approached in these beds. Taxonomic composition of the deep coal-bearing communities profoundly

    The Oman Drilling Project drilled holes at four sites in a transect through the southern massifs of the Samail ophiolite, and recovered 1500 m of igneous and metamorphic rocks. We focus on three sites from the oceanic crustal section including lower layered gabbros (GT1A), the mid-crustal layered to foliated gabbro transition (GT2A), and the shallower transition from sheeted dikes to varitextured gabbros (GT3A). Detailed core descriptions, analyses, and paleomagnetic measurements, were made on D/V Chikyu from July to September 2017 to utilize the core laboratory facilities similar to IODP expeditions. Shipboard measurements included anisotropy of magnetic susceptibility (AMS) and alternating field and thermal demagnetization of 597 discrete samples. Sample demagnetization behavior is varied from each of the cores, with some revealing multiple components of magnetization, and others yielding nearly univectorial data. The interpretation of results from the lower crustal cores is complicated by the pervasive presence of secondary magnetite. In almost all samples, a stable component was resolved (interpreted as a characteristic remanent magnetization) after removal of a lower-coercivity or lower unblocking-temperature component. The inclinations of the stable components in the core reference frame are very consistent in Hole GT1A. However, a transition from negative to positive inclinations in GT2A suggests some structural complexity, possibly as a result of intense late faulting activity. Both abrupt and gradual transitions between multiple zones of negative and positive inclinations occur in Hole GT3A. Interpretation and direct comparison of remanence between drill sites is difficult as recovered core pieces currently remain azimuthally unoriented, and GT2A was drilled at a plunge of 60°, whereas GT1A and GT3A were both drilled vertically. Work is ongoing to use borehole imagery to reorient the core pieces and paleomagnetic data into a geographic in situ reference

    Determining the azimuthal orientation of core samples obtained from deep drilling is extremely difficult because the core itself could have rotated during drilling operations. Several indirect methods have been devised to address this issue, but have certain limitations. Thus it is still a challenge to determine the azimuthal orientation consistently over the entire length of the hole. Provided that the recovery rate is high and thus all the other magnetic properties such as magnetization intensity and inclination are measured from the recovered cores, one possible method for ascertaining magnetic declination information is to measure the magnetic field inside the empty borehole and invert for the best fitting declination. However, there are two major problems: one is that present-day borehole magnetometers are not precise enough to resolve changes in direction of magnetization, and the other is that in most rock drilling experiments the rate of recovery is low. To overcome the first major problem which is technical, scientists from Korea and Japan jointly conducted the development for the next-generation borehole magnetometer, namely 3GBM (3rd Generation Borehole Magnetometer). The borehole magnetometer which uses fiber-optic laser gyro promises to provide accurate information on not only the magnetic field itself but also the orientation of the instrument inside the borehole. Our goal is to deploy this borehole magnetometer in the ICDP Oman Drilling Project Phase 2 drilling experiment early 2018. The site may be suitable for the investigation because, as recent Phase 1 of the Oman Samail Ophiolite drilling has demonstrated, the recovery rate was very high. Also the post-drilling measurements onboard DV Chikyu have shown that much of the recovered samples has moderate magnetization intensity on the order of 0.1 and 1 A/m. Here, we present the results of numerical simulation of magnetic field inside the borehole using finite element method to show that magnetic

    Hole GT2A (UTM: 40Q 655960.7E / 2529193.5N) was drilled by the Oman Drilling Project (OmDP) into Wadi Gideah of Wadi Tayin massif in the Samail ophiolite, Oman. OmDP is an international collaboration supported by the International Continental Scientific Drilling Program, the Deep Carbon Observatory, NSF, IODP, JAMSTEC, and the European, Japanese, German and Swiss Science Foundations, with in-kind support in Oman from the Ministry of Regional Municipalities and Water Resources, Public Authority of Mining, Sultan Qaboos University, and the German University of Technology. Hole GT2A was diamond cored in 25 Dec 2016 to 18 Jan 2017 to a total depth of 406.77 m. The outer surfaces of the cores were imaged and described on site before being curated, boxed and shipped to the IODP drill ship Chikyu, where they underwent comprehensive visual and instrumental analysis. 33 shipboard scientists were divided into six teams (Igneous, Alteration, Structural, Geochem, Physical Properties, Paleomag) to describe and analyze the cores. Hole GT2A drilled through the transition between foliated and layered gabbro. The transition zone occurs between 50 and 150 m curation corrected depth (CCD). The top 50 m of Hole GT2A is foliated gabbro whereas the bottom 250 m consists of layered gabbro. Brittle fracture is observed throughout the core. Intensity of alteration vein decreases from the top to the bottom of the hole. On the basis of changes in grain size and/or modal abundance and/or appearance/disappearance of igneous primary mineral(s) five lithological units are defined in Hole GT2A (Unit I to V). The uppermost part of Hole GT2A (Unit I) is dominated by fine-grained granular olivine gabbro intercalated with less dominant medium-grained granular olivine gabbro and rare coarse-grained varitextured gabbro. The lower part of the Hole (Units II, III and V) is dominated by medium-grained olivine gabbro, olivine melagabbro and olivine-bearing gabbro. Modally-graded rhythmic layering with

    Multiple lines of evidence exist for a range of sediment mass movement processes within the shallow megasplay fault zone (MSFZ) area and the adjacent slope basin in the outer fore-arc of the Nankai subduction zone, Japan. Diagnostic features observed in 3-D reflection seismic data and in cores from Integrated Ocean Drilling Program (IODP) Expedition 316 document a complex mass movement history spanning at least ˜2.87 million years. Various modes and scales of sediment remobilization can be related to the different morphotectonic settings in which they occurred and allow integration of knowledge on the spatial and temporal distribution of submarine landslides into a holistic reconstruction of the tectonostratigraphic evolution. New data from the most-recent Nankai IODP Expedition 333, which drilled and cored a Pleistocene-to-Holocene succession of the slope-basin seaward of the MSFZ, provides unprecedented details on submarine landslide processes occurring over the last Million year. The slope-basin represents the depocentre for downslope sediment transport and is characterized in 3-D reflection seismic data by several mass-transport deposits (MTDs), including an up to 180 m thick MTD. Here we present D/V Chikyu shipboard results and first post cruise results from Site C0018, including litho- bio- magneto- tephra- and stable isotope-stratigraphy, X-ray computed tomography analysis and physical properties data. Six MTDs were identified from visual core description and X-ray CT-scans. The thickest MTD is also the oldest (emplaced between 0.85 and 1.05 Ma) and it coincides with a lithological transition between a sandy turbidite sequence below, and ash-bearing hemipelagites comprising several MTDs above. Deformation styles within the MTD are heterogeneous: intervals of disturbed sediments are interbedded within intervals inferred to retain original, coherent bedding. In three occurrences the base of the MTD is defined by a shear zone within fine-grained sediments

    Mission Specific Platform (MSP) expeditions are operated by the European Consortium for Ocean Research Drilling (ECORD). Each MSP expedition is unique within the Integrated Ocean Drilling Program (IODP). In order to complement the abilities of the JOIDES Resolution and the Chikyu, the ECORD Science Operator (ESO) must source vessels and technology suitable for each MSP proposal on a case-by-case basis. The result is that ESO can meet scientific requirements in a flexible manner, whilst maintaining the measurements required for the IODP legacy programme. The process of tendering within EU journals for vessels and technology means that the planning process for each MSP Expedition starts many years in advance of the operational phase. Involvement of proposal proponents from this early stage often leads to the recognition for technological research and development to best meet the scientific aims and objectives. One example of this is the planning for the Atlantis Massif proposal, with collaborative development between the British Geological Survey (BGS) and MARUM, University of Bremen, on suitable instruments for seabed drills, with the European Petrophysics Consortium (EPC) driving the development of suitable wireline logging tools that can be used in association with such seabed systems. Other technological developments being undertaken within the European IODP community include in-situ pressure sampling for gas hydrate expeditions, deep biosphere and fluid sampling equipment and CORK technology. This multi-national collaborative approach is also employed by ESO in the operational phase. IODP Expedition 302 ACEX saw vessel and ice management support from Russia and Sweden to facilitate the first drilling undertaken in Arctic sea ice. A review of MSP expeditions past, present and future reveal the significant impact of European led operations and scientific research within the current IODP programme, and also looking forward to the start of the new International

    The year 2017 represents the 60th anniversary of the "original" project Mohole, which was coined by Walter Munk in 1957. Although the project Mohole has not yet been realized, the hard-rock community is now striving hard to understand the upper mantle in a variety of ways. Firstly, the present-day project Mohole, M2M (Moho-to-Mantle) project, will move forward in this September, conducting multi-channel seismic profiling off Hawaii as a site survey. Oman Drilling Project has started last December, and the drilled cores are being described aboard D/V Chikyu from July, this year. Furthermore, the forearc M2M proposal to drill the Bonin Trench forearc mantle was submitted to IODP in April 2016. Being a part of these efforts, we are preparing an IODP proposal to drill the Godzilla Megamullion, the largest known oceanic core complex on the Earth, located in the Parece Vela Basin in the Philippine Sea. A significant fraction of the ocean floor is created in backarc basins, while there have been no single long core of backarc basin lower ocean crust, from which to understand the likely differences in magmatic evolution and crustal structure in this key setting. The opportunity to explore the formation of the backarc basin lower crust and upper mantle is, therefore, an important contribution to understanding the ocean basins. At the same time, a better understanding of the architecture of backarc basin lower crust and upper mantle will greatly aid in the interpretation of the results of ophiolite study, since much of our understanding of the architecture of oceanic lower crust and upper mantle comes from ophiolites, most of which are thought to have at least some arc and/or backarc component. The Godzilla Megamullion is unique in its huge size as well as its development in a backarc basin, a rare tectonic window to study backarc basin lithosphere. The Godzilla Megamullion is prepared for full drilling proposal, with complete bathymetric data, multiple bottom samplings, and

    Expedition 370 of the International Ocean Discovery Program (IODP) aimed to explore the limits of life in the deep subseafloor biosphere at a location where elevated heat flow lets temperature increase with sediment depth beyond the known maximum of microbial life ( 120°C) at 1.2 km below the seafloor. Such conditions are met in the protothrust zone of the Nankai Trough off Cape Muroto, Japan, where Site C0023 was established in the vicinity of ODP Sites 808 and 1174 at a water depth of 4776 m using the drilling vessel DV Chikyu. Hole C0023A was cored down to a total depth of 1180 meters below seafloor, offshore sampling and research was combined with simultaneous shore-based investigations at the Kochi Core Center (KCC), and long-term temperature observations were started (Heuer et al., 2017). The primary scientific objectives of Expedition 370 are (a) to detect and investigate the presence or absence of life and biological processes at the biotic-abiotic transition of the deep subseafloor with unprecedented analytical sensitivity and precision; (b) to comprehensively study the factors that control biomass, activity, and diversity of microbial communities; and (c) to elucidate if continuous or episodic flow of fluids containing thermogenic and/or geogenic nutrients and energy substrates support subseafloor microbial communities in the Nankai Trough accretionary complex (Hinrichs et al., 2016). This contribution will highlight the scientific approach of our field-work and preliminary expedition results by shipboard and shorebased activities.

    Quantified grid observation data at a reasonable resolution are indispensable for environmental monitoring as well as for predicting future change of mountain environment. However quantified datasets have not been available for the Himalayan region. Hence we evaluate climatological precipitation data around the Himalayas by using Precipitation Radar (PR) data acquired by the Tropical Rainfall Measuring Mission (TRMM) over 10 years of observation. To validate and adjust these patterns, we used a dense network of rain gauges collected by the Asian Precipitation—Highly Resolved Observational Data Integration Towards Evaluation of Water Resources (APHRODITE Water Resources) project (http://www.chikyu.ac.jp/precip/). We used more than 2600 stations which have more than 10-year monthly precipitation over the Himalayan region (75E-105E, 20-36N) including country data of Nepal, Bangladesh, Bhutan, Pakistan, India, Myanmar, and China. The region we studied is so topographically complicated that horizontal patterns are not uniform. Therefore, every path data of PR2A25 (near-surface rain) was averaged in a 0.05-degree grid and a 10-year monthly average was computed (hereafter we call PR). On the other hand, for rain-gauge, we first computed cell averages if each 0.05-degree grid cell has 10 years observation or more. Here we refer to the 0.05-degree rain-gauge climatology data as RG data. On the basis of comparisons between the RG and PR composite values, we defined the parameters of the regressions to correct the monthly climatology value based on the rain gauge observations. Compared with the RG, the PR systematically underestimated precipitation by 28-38% in summer (July-September). Significant correlation between TRMM/PR and rain-gauge data was found for all months, but the correlation is relatively low in winter. The relationship is investigated for different elevation zones, and the PR was found to underestimate RG data in most zones, except for certain zones in

    sedimentation during the crisis? What are the vertical movements (tectonic/isostatic responses) associated to margin unloading and basin loading? - What are the present-day fluid dynamics related to the salt layer? Their impact on the deep biosphere? The response to all of these questions would only come from drilling through the complete Messinian succession. It would represent an outstanding opportunity to unravel the history of extreme environmental changes during the Messinian and a unique chance to constrain the age, nature and paleo-environment of deposition of the deep-basin Messinian sequence. For that reason, in the framework of the IODP drilling program, we propose to sample and log two different sites in the western and eastern Mediterranean basins, with the new scientific riser drillship Chikyu perfectly adapted to overcome all safety problems. In order to promote a continuous sedimentary record of the MSC since the pre-crisis paleo-environmental changes, the sites should be drilled in areas where the Messinian salt is tabular and exempted of significant tectonic influence. A complete set of integrated studies (sedimentology, geochemistry, micropaleontology, bio-and cyclostratigraphy) should be carried out. This project opens the perspective of a new intellectual and scientific adventure that we expect to be as rich and exciting as the discovery of this unusual event was.

    Blake Ridge in the Atlantic Ocean in 1995, have also contributed greatly to our understanding of the geologic controls on the formation, occurrence, and stability of gas hydrates in marine environments. For the most part methane hydrate research expeditions carried out by the ODP and IODP provided the foundation for our scientific understanding of gas hydrates. The methane hydrate research efforts under ODP-­‐IODP have mostly dealt with the assessment of the geologic controls on the occurrence of gas hydrate, with a specific goal to study the role methane hydrates may play in the global carbon cycle.Over the last 10 years, national led methane hydrate research programs, along with industry interest have led to the development and execution of major methane hydrate production field test programs. Two of the most important production field testing programs have been conducted at the Mallik site in the Mackenzie River Delta of Canada and in the Eileen methane hydrate accumulation on the North Slope of Alaska. Most recently we have also seen the completion of the world’s first marine methane hydrate production test in the Nankai Trough in the offshore of Japan. Industry interest in gas hydrates has also included important projects that have dealt with the assessment of geologic hazards associated with the presence of hydrates.The scientific drilling and associated coring, logging, and borehole monitoring technologies developed in the long list of methane hydrate related field studies are one of the most important developments and contributions associated with methane hydrate research and development activities. Methane hydrate drilling has been conducted from advanced scientific drilling platforms like the JOIDES Resolution and the D/V Chikyu, which feature highly advanced integrated core laboratories and borehole logging capabilities. Hydrate research drilling has also included the use of a wide array of industry, geotechnical and multi-­‐service ships. All of
