TitleInternational Cooperation in Earth Planetary Science Project -Centering on NASA-JAXA Joint Project-
Scope In such a big project of the earth planetary science, it would be an inevitable process to organize an international cooperation framework. Especially in Japan, we have been working together in various fields with NASA, the pioneer in the field. Initiated by the Halley's Comet exploration program in the Cold War era under the framework called IACG (Inter-Agency Consultative Group for Space Science), international collaboration is crucial for planetary science in Japan. There are several ongoing US-Japan collaborations and this time we would like to focus on two satellites, namely GEOTAIL and HINODE. The former one was the 1st satellite of the International Solar Terrestrial Physics program (ISTP) armada and was launched in 1992. The satellite is still active and all the Japan and US instruments onboard are sending in-situ plasma data in the magnetosphere. HINODE is the space solar observatory and was launched in 2006. Solar Optical Telescope (SOT) and X-ray Telescope (XRT) were made fully/partially in the US. In the earth environmental observation, along with the joint missions where JAXA observation instruments load on the NASA satellites, and visa-versa, most recently, there has been a cooperation where JAXA GCOM-W satellite joined in the NASA A-train. In the next fiscal year, Global Precipitation Measurement (GPM), which is an equal-partner project, will be launched. Regarding the world-leading international project that are using the most of the respective specialities in the field and technology from Japan and America, we aim to deepen our understanding to the meaning of the global cooperation itself and to the future prospect, by gathering in this union conference and holding a session.

TitleGlobal Data Sciences in the Big Data Era
Scope In earth, planetary and space sciences, scientific findings and understanding of irreproducible phenomena like earth's climate change etc. cannot be validated with double-check of results by independent scientists which is essential elements of the modern science. Then, "data" is the only proof which scientists can show to the society to secure the scientific truth. The ICSU-WDS (World Data System) progarmme has started its international programme office (IPO) hosted in Japan targets world-scale data-sharing community and framework. New initiatives such as persistent digital identifiers of datasets and authors, as well as data citation are important as a new science infrastructure in this new era. Nowadays when decision-makers requires access to usable information on natural phenomena which impacts the society, joint efforts and possible collaboration, and furthermore fusion are required of advanced information science and technology together with earth and planetary science datasets, so targeted activities like DIAS are proceeding now. In this session, a wide range of data activities of not only earth and planetary sciences but also of social and economic fields are welcome to exchange and interact for the future global coordination of scientific data and information.

TitleRotational motion and inner dynamics of the Earth, Mars and Moon
Scope Dynamic studies of rotational motions of celestial bodies give the important key to understanding of their internal structure, gravitational fields and dynamics of their shells. Due to space missions of last time and precision radar and laser observations from the Earth the extremely important data on rotational motions of Mercury, the Moon, Mars, the Titan and other bodies of solar system are obtained. An increase of accuracy of observations of rotation of Mercury and the Moon in the nearest years is expected. Rotations and internal structures of solar system bodies have as the general properties so find out also the important specific features (resonant character of motion, presence of a liquid core, presence of liquid ocean shells, a massive atmosphere at the resonant satellite of the Titan and others). These features of celestial bodies result in necessity of development of new approaches and methods for construction of analytical theories of their rotation. The basic purpose - in work of the given session is to combine and systematize studies of rotational motions of solar system bodies in view of their multilayered structure in first for the Earth, Mars and the Moon. The reports reflecting researches on the following themes are invited. The construction of analytical and semi - analytical theories of rotation of the Moon, Mars and other bodies of Solar System. Researches of gravitational fields and an internal structure of bodies of solar system, construction of their models. Tidal deformations of the surface of the Moon and Mars. Researches of rotational motions of the Earth and Mars as systems of interacting shells (solid core, liquid core, mantle). New methods of study of rotational motion of the Moon. Dynamics of relative oscillations of the shells of celestial bodies (differential rotations and small translational relative displacements). Studies of tidal evolution of rotational motions etc.

TitleRemote Sensing of Lightning, TLEs and their Atmospheric Effects
Scope Lightning is the energetic manifestation of electrical breakdown, occurring after charge separation processes operating on micro and macro-scales, leading to strong electric fields within thunderstorms. Lightning is always associated with severe weather and tropical storms like typhoons and hurricanes, often accompanied by torrential rains and flash floods. It has significant chemical and physical effects on the troposphere and mesosphere and drives the fair-weather electric field. This session seeks contributions on the meteorology of thunderstorms, the detection of thunderstorms from space and ground networks, the climatic effects of thunderstorms and their impact on the global circuit, and lightning in relation with middle atmospheric transient luminous events (e.g sprites).

TitleToward Understanding of interactions between Tropical Cyclones and the Ocean
Scope Tropical cyclones (TCs) are one of the most destructive atmospheric phenomena that cause tremendous damages and loss of life due to strong winds, torrential rainfall and storm surges. Ocean, the large reservoir of heat content, is an indispensable partner for TCs: Genesis of TCs occurs over warm ocean areas. Strong winds around the TCs drive the upper ocean current and lead to the physical and biochemical oceanic response during their lifetime. Sea-surface cooling induced by TCs has a negative effect on TC intensification and thus contributes to the maintenance of its intensity. Therefore, understanding of the interactions between TCs and the ocean contributes to the improvement of TC intensity prediction, particularly in the Western North Pacific and Atlantic Ocean wherethe interactions are strong. Other interactions address the influence of oceanic mesoscale eddies, air-sea interface processes such as momentum, heat and carbon exchange under the extremely high ocean waves and sea spray conditions and their bio-chemical reactions. However, current understanding of the interactions is still limited. This session welcomes submissions under the broad field of studies on TC-ocean physical and biogeochemical interactions by the use of observation, theory, numerical modeling and data assimilation in all ocean basins ranging from weather-forecasting to climate time scales.

TitleChanges in Northern Eurasia and the Arctic: Their feedbacks to the Globe
Scope The Northern Eurasia Earth Science Partnership Initiative (NEESPI) was launched as an interdisciplinary program of internationally-supported Earth science research addressing large-scale and long-term manifestations of climate, environmental, and socioeconomic changes (focusing on Northern Eurasia) that affect the rate of global change through atmosphere-biosphere-cryosphere interactions and through strong biogeophysical and biogeochemical couplings. The goal of the proposed Session is to bring together scientists who conduct their studies in the region to share their findings, to discuss the yet unresolved problems, and to establish fruitful collaboration within a broad range of the disciplines and research groups. We invite presentations on the biogeochemical cycles, the surface energy budget and water cycle, climate and terrestrial ecosystems interactions (land cover and land use, atmospheric aerosols, soil, permafrost, and, in particular, changes in the high latitudes of Eurasia (tundra and taiga climatic zones) and weather extreme changes that affect and are being affected by climate and ecosystems changes), human dimension that includes, in addition to regional impact studies of environmental changes, the feedback studies of societal and land use changes on regional and global environment and climate, and tools to address the Northern Eurasia and the Arctic studies (paleoclimatic reconstructions, present and past field campaigns, remote sensing, and modeling). Since the past year, the particular focus of the international NEESPI Sessions has been on the studies of the early career scientists. Participation in one of the 150 NEESPI projects is not a prerequisite and representatives of each research group that studies the North Eurasian Earth System are welcome.

TitleMulti-scale ocean-atmosphere interaction in the tropics
Scope El Nino/Southern Oscillation, Indian Ocean Dipole, Atlantic Nino, and Atlantic Meridional Mode are ocean-atmosphere interaction phenomena in the tropics. These phenomena have an interannual timescale of two- to seven-year period. It has been pointed out that they are related to various phenomena of shorter (e.g., intraseasonal) and longer (e.g., quasidecadal to multidecadal) timescales as well as phenomena of various spatial scales. In addition to interactions among the tropical phenomena and climate change, links with atmospheric and oceanic variations in mid to high latitudes have been discussed in past studies. These phenomena strongly affect weather, climate, and climate variations over the globe including those in Japan. To enhance our understanding of variability of tropical ocean-atmosphere interaction phenomena and other related phenomena, cooperation between various fields (meteorology, oceanography, climatology, etc.) needs to be strengthened. In this session, presentations and discussions about interannual tropical ocean-atmosphere interaction phenomena, Madden-Julian Oscillation (MJO), tropical cyclones (typhoon), quasi-decadal to multi-decadal variations and other related phenomena by various researchers of atmosphere and ocean, weather and climate, and tropics and extra-tropics, will be carried out to promote research on spatial and temporal multi-scale ocean-atmosphere interaction phenomena in the tropics. We welcome submissions on theoretical, observational, and modeling studies.

TitleNatural hazard impact on technological systems and urban areas
Scope Recent years set a sad record in the number and scale of natural disasters and clearly demonstrated high vulnerability of the human society and technosphere to their impact. The most serious consequences have the so-called natural-technological disasters that have place when natural hazards trigger accidents at technological objects such as nuclear power plants, chemical plants or oil refineries and pipelines. One of the most large-scaled natural-technological disasters occurred on March 11, 2011 in Japan as a result of a massive 9.0-magnitude earthquake off the northeast coast of Honshu Island, that caused a more than 30-meter tsunami. A distinctive feature of natural-technological events, such as of the 2011 Tohoku earthquake, is their synergistic nature with a disaster impact on the technosphere, resulting in simultaneous occurrences of numerous technospheric accidents. Usually it is very difficult to deal with the consequences of such natural-technological accidents and disasters, because one has to cope not only with the primary aftermaths of the natural disaster, but also with the secondary effects of a number of technological accidents, which can be much more serious. These consequences are the more severe the higher are the population density and concentration of industrial facilities and infrastructure (especially hazardous objects) in disaster-affected areas. The main goal of this session is to summarize case studies of relationships between natural hazards and technological disasters and to encourage a discussion about tools and methods to prevent or minimize their consequences.

TitleSlip to the Trench in Megathrust Earthquakes
Scope Seismological, tsunami, and geodetic data of the 2011 Tohoku-oki earthquake indicate large slip of more than 50 m on the shallow part of the subduction megathrust. Coseismic slip reaching the trench has been inferred from comparisons of seismic and bathymetry images before and after the earthquake. At the Nankai Trough, ocean drilling provided frictional-heating evidence for seismic slip of a frontal thrust. In addition, anomalous slip of the shallow megathrust producing so-called tsunami earthquakes has occurred at several subduction zones. Recent friction experiments suggest that earthquake rupture propagates easily through velocity-strengthening materials by high-velocity weakening. These observations suggest a need to re-examine the widely accepted conceptual model of megathrust slip behavior, especially for the near-trench shallow portion. This session will integrate field observations, experimental results and modeling studies to understand seismic and aseismic slip of the shallow part of the subduction fault.

TitleEarthquake predictability research after the 2011 Tohoku earthquake
Scope Modern earthquake science requires rigorous experimentation. Earthquake predictability studies (e.g. Collaboratory for the Study of Earthquake Predictability) emphasize the importance of testing earthquake forecast models so far. Japan, California, New Zealand and other regions are currently operating or developing regional centers for such tests, and the findings may yield a better understanding not only of the models' basic features but also of particular physical aspects of earthquake occurrence. We solicit presentations about forecast models, their components, and their performance, in particular statistical models. Especially, we would like to discuss problems in forecasting large earthquakes such as recent devastating events in Japan and New Zealand.

TitleEarth and Planetary Cores Seen from Multi-disciplinary Approaches
Scope Recently, the physical properties relating to the Earth's core are revisited under exact conditions. Their new features activate many discussions: for example, hexagonal close-packed iron may be nearly isotropic, which requires a new mechanism of inner core anisotropy; thermal conductivity may be 2-3 times larger than the previous estimates, which inhibits vigorous convection in the outer core and requires a young inner core. We can find the Earth's core is still a mysterious region. As for the core of the other planetary body, the Moon's core is discovered by using Apollo seismic data, which should be confirmed and further constrained by new scientific project with modern techniques. Here we would like to have an opportunity to discuss recent advances and exchange interesting ideas about the Earth's and planetary cores. We welcome any papers from any discipline, such as mineral physics, geomagnetism, geodynamics, seismology and any other relevant fields.

TitleOrigin, evolution, and destruction of oceanic plate
Scope Formation and subduction of oceanic plate play an important role in the thermochemical evolution of the Earth interior and surface environmental conditions including biological activities. However, we have never clearly answered basic questions: such as (1) Origin and modification (metamorphism and alteration coupled with biological activities) of oceanic plate before and after subduction, (2) Impact of destruction of oceanic plate on subduction zone processes, such as volcanism and earthquake, (3) Differences between mid-ocean ridge and back arc settings. In order to understand the origin, evolution and deconstruction of oceanic plate, the session invites contributions from a range of geophysics, geochemistry, petrology, modeling, simulation and biology working on intact as well as fossil oceanic lithosphere, e.g., ophiolite.

TitleGeofluids and their roles in dynamics of the Earth's interior
Scope Fluids on the surface and in the interior of the Earth may play crucial roles in terrestrial dynamics and evolution of a wide spectrum of phenomena in time and space, e.g., active tectonics such as earthquakes, slow fault slip, magmatism, hydrothermal activity to long-term orogeny with metamorphic complex and continental evolution. How much and where do fluids actually exist, and which evidence is sensitive? What are the fluid pathways and how fast do fluids migrate? How much do they reduce mechanical strength, induce rock failure, or enhance melting? Geofluids must carry various (but specific) chemical components. How much do they migrate and thereby contribute to formation of ore and continental crust? Geological, geophysical and geochemical methods are all necessary to address these questions, and we highly welcome various contributions from observational, experimental and theoretical approaches.

TitleCollision, Subduction, and Metamorphic processes
Scope This session is aimed at considering the processes involved with the continental collision, slabs subduction and related metamorphic processes. The multi-disciplinary approach will be applied to extract the information preserved in various rocks and minerals via structural, geophysical, petrologic, geochemical and experimental studies. These include formation processes of new minerals/textures, their growth history and recrystalization, inclusion morphology, and metamorphic reactions. Topics related to rocks and minerals formed in the processes of continental collisions, oceanic subductions, and regional metamorphisms are most welcome from the major orogenic belts worldwide. Topics in this session also include links between hydration and dehydration along the subduction channels, cycling of continental crust, deformation mechanisms in the subduction, collision regimes, formation and exhumation of various metamorphic rocks such as granulites, blueschist and HP/UHP eclogites and other metamorphic rock types.The session also aims at exchanging ideas among geoscientists applying different approaches on problems related to the subducting slabs, collision boundaries and related metamorphic processes. New works with novel or interdisciplinary techniques to the related theme are especially welcomed.

TitleGeodynamics of off-arc volcanism and back-arc opening
Scope Deployments of large-scale, high-density seismic arrays around the world have started to reveal regional-scale, upper mantle structures with unprecedented detail. Such improved imaging is crucial to elucidating long-standing tectonic questions such as the links between surface tectonics and volcanism. For example, NECESSArray consists of 120 broadband stations deployed in northeast China (2009-2011). The region is known to display puzzling, Cenozoic intraplate and off-arc volcanism, but the relationship with the stagnant slab beneath the Japan Sea, if any, has been debated. Preliminary tomographic images from NECESSArray reveal an unexpected result; the absence of a long-tailed, stagnant slab beneath the chain of volcanoes, suggesting a possible link of volcanism either to the mantle transition zone, or the lower mantle. This finding opens a new discussion on the origin of off-arc volcanism and back-arc opening in the wider context of global geodynamics. We solicit contributions from geologists, petrologists, geochemists, geophysicists, geodynamicists, and seismologists working on related problems in the NW Pacific subduction zone and other similar, or contrasting, subduction zone settings world wide.

TitleEvolution of continental crust and Project IBM
Scope Key questions for comprehending arc crust formation are: (1) What is the nature of the crust and mantle in the region prior to the beginning of subduction? (2) How does subduction initiate and initial arc crust form? (3) What are the spatial changes of arc magma and crust composition of the entire arc? (4) How do the middle arc crust evolve? This session aimed to gather a wide range of geophysicists, geologists, geochemists and petrologists who are interested in the nature and evolution of arc crust and how this is modified in collision zones and preserved in continental crust. IODP has Project IBM proposals to drill at the IBM, including three non-riser holes (IBM-1, IBM-2 and IBM-3) and one riser, ultra-deep hole (IBM-4). The total four drillings should result in comprehensive understanding of the arc evolution and continental crust formation. JR drilling at three sites (IBM-1, IBM-2 and IBM-3) is scheduled in 2014 from 31 March to 23 September, six months in total. Ultra-deep drilling (IBM-4) is now in OTF and its drilling will be discussed in the Chikyu workshop in April, 2013. Genesis of continental crust will be tackled from both a land-based study and a sea-based study.

TitleBiocalcification and the geochemistry of proxies
Scope In order to reconstruct the Earth climate system, marine paleoclimatologists resort to transferfunctions or geochemical proxies, which are produced or affected by organisms. The relationships used forreconstructions are generally based on field calibrations or derived from laboratory experiments. The danger ofthese so called empirical relationships is that they maybe valid only within the restricted parameter space of theircalibration. Application of proxy relationships to very different environmental settings (e.g. high vs. low latitude orglacial vs. interglacial) requires a mechanistic understanding of these relationships. Much progress can beexpected by a better understanding of the biocalcification mechanisms and the incorporation of proxy signals.In this session we invite contributions related to the biocalcification, calibration and validation of marine proxies.

TitleGlobal Data Sciences in the Big Data Era
Scope In earth, planetary and space sciences, scientific findings and understanding of irreproducible phenomena like earth's climate change etc. cannot be validated with double-check of results by independent scientists which is essential elements of the modern science. Then, "data" is the only proof which scientists can show to the society to secure the scientific truth. The ICSU-WDS (World Data System) progarmme has started its international programme office (IPO) hosted in Japan targets world-scale data-sharing community and framework. New initiatives such as persistent digital identifiers of datasets and authors, as well as data citation are important as a new science infrastructure in this new era. Nowadays when decision-makers requires access to usable information on natural phenomena which impacts the society, joint efforts and possible collaboration, and furthermore fusion are required of advanced information science and technology together with earth and planetary science datasets, so targeted activities like DIAS are proceeding now. In this session, a wide range of data activities of not only earth and planetary sciences but also of social and economic fields are welcome to exchange and interact for the future global coordination of scientific data and information.

TitleActivity of GEO task "Integrated Global Carbon Observation and Analysis System (CL-02)" in Japan
Scope The GEO CL-02 task, entitled "Integrated Global Carbon Observation and Analysis System," is registered in the work plan for the period of 2012-2015 of the Group on Earth Observation. Its description is Develop a comprehensive global carbon observation and analysis system integrated across the atmosphere, land and ocean (including anthropogenic) domains. Provide (i) improved estimates of carbon budget at different scales (from global to regional/national); and (ii) reliable information and products for decision-makers. Improve global observation networks of CO2, CH4, isotope ratios and exchange fluxes. Develop an integrated carbon-cycle data assimilation system. Provide communication points to increase the information flow from providers to users, and disseminate current state-of-the-art information. However, in the last work plan symposium in May 2012 in Geneva, it was pointed out that this task was not well coordinated. Although some institutions in Japan join this task, the available information was limited. To enhance the communication, exchange of information and collaborative activity in Japan, this session has been proposed. For this session, oral and poster presentations will be accepted not only from the group of the registered task contributors but also from the potential contributors in a broad range of disciplines.

TitleNew atmospheric and geospace science opened by EISCAT_3D
Scope EISCAT-3D is major upgrade of the existing EISCAT radars in the northern Scandinavia (http://www.eiscat3d.se/). With a multi-static phased array system composed of one central active (transmit-receive) site and several receive-only sites, the EISCAT-3D system is expected to provide 10 times higher temporal and spatial resolution and capabilities than the present radars. Main objectives of this session are (1) to discuss scientific targets which are to be solved by EISCAT_3D, (2) to exchange new ideas among scientists who are interested in atmospheric and geospace science using EISCAT_3D, and (3) to discuss widely how we can propose to join the EISCAT_3D consortium. EISCAT_3D is a 3-dimensionally imaging incoherent scatter radar system planned by the EISCAT Scientific Association and associate members for years. The new radar is envisaged to overcome the present observational limits and provide scientific breakthrough by its excellent high time resolution and 3D measurement capability of the near earth plasma-atmosphere coupling in the auroral oval and at the edge of the polar vortex. Scientific topics to be addressed by EISCAT_3D are listed as follows: (1) Influence of natural solar-terrestrial variability on atmosphere and climate, (2) Aurora and field-aligned current system, (3) Ion upflow phenomena, (4) Long-term change due to human activity, (5) Coupling between atmospheric layers, (6) Space plasma physics, (7) Measurements of solar wind and corona, (8) Effects of meteors and energetic particles, (9) Monitoring of space weather, (8) Orbit determination of space debris and meteors, and (10) Radar mapping of near-Earth objects. We are looking forward to having many contributing papers from wide research communities in order to exchange valuable ideas and discussions regarding the international EISCAT_3D program.
