Union Session in JpGU Meeting 2011

Sessions to present the up-to-date frontier topics of the earth and planetary sciences covered by JpGU, or to treat subjects which are of common interest to the whole geosciences community.
The Nine of Union Sessions in JpGU Meeting 2011 are described below.

U-01	System of Water, Atmosphere and Human in Coastal Megacities	Maki Tsujimura	(Graduate School of Life and Environmental Sciences, University of Tsukuba)
	Water, mass and atmospheric cycle occurs dynamically interacting with variety of human activities in coastal megacities of Asian regions. The coastal megacities discharge a lot of load into the sea, and concurrently these regions have a potential of purification under the balance between nature and humanity. This session will discuss the issues and the future capability of water-atmosphere-human system in the coastal megacities from the various view points of hydrology, water resources, meteorology, environmental sciences, geochemistry and geography.

U-02	New perspective of great earthquakes along subduction zones	Kyuichi Kanagawa	(Graduate School of Science, Chiba University)
	We explore a new perspective of great earthquakes along subduction zones by integrating results of paleoseismological surveys, variable observations, laboratory experiments, material analyses, and numerical modeling on pre- and co-seismic processes, seismic links, and the recurrence. We welcome presentations not only on great earthquakes as those along the Nankai Trough, the Sunda and Chile Trenches, etc., but also on large inland earthquakes.

U-03	New results from Venus Climate Orbiter AKATSUKI	Masahiro Takagi	(Department of Earth and Planetary Science, Graduate School of Science, University of Tokyo)
	The Venus Climate Orbiter Akatsuki has failed to enter Venus orbit. The cause and the current status are under investigation. We believe that future possibilities of observations have not been lost. This session is intended for broad discussion about recover plans of the Akatsuki project, studies in close collaboration with the Venus Express project, and future Venus missions. Any input from dynamical modeling and ground-based observations is also welcome.

U-04	Global Data System for Earth and Planetary Sciences	Hiroo Hayashi	(Research Institute for Sustainable Humanosphere, Kyoto University)
	As the earth, planetary and space sciences advance and the public concerns for our study increase, we now have to analyze huge, various kinds of multi-disciplinary data and then to promptly publish research results. This promotes development in e-infrastructure for science, e.g., reorganizing international data groups, standardizing data formats, building metadata databases, producing integrated analysis tools, and installing high-speed data links. We will discuss our efforts and seek to cooperate in developing the e-infrastructure in future.

U-05	New planetary science arising from"HAYABUSA" recovery sample	Toshifumi Mukai	(Japan Aerospace Exploration Agency)
	Return capsule of the asteroid exploration spacecraft "HAYABUSA", which tried the sample collection from the asteroid Itokawa for the first time and succeeded in the earth return, was recovered safely in June, 2010. In this session, we will discuss results of the curation work and preliminary analyses of the recovered samples in expectation of new planetary science. However, there is a possibility of changing the content of the session depending on the progress situation of the research.

U-20	Interrelation between Life, Water, Mineral and Atmosphere	Yoshio Takahashi	(Department of Earth and Planetary Systems Science, Graduate School of Science, Hiroshima University)
	Life in Earth is based on a diversity of physical and chemical dynamism and processes of Earth in the 4 billion years of history. Its nature is the interrelation between Life, Water, Mineral (Solid Earth) and Atmosphere. Interdisciplinary approach, way of thinking and communication are necessary. This session will be a cradle for such kind of interdisciplinary research.

U-21	Problems on forecasting earthquakes and volcanic eruption	Naoji Koizumi	(National Institute of Advanced Industrial Science and Technology, Active Fault and Earthquake Research Center)
	Italian government's Civil Protection Agency made no effective warning about the 2009 L'Aquila earthquake, which killed more than 300 people, and it has been blamed by citizens. In June,2010 the L'Aquila public prosecutor's office named several scientists as being investigated for manslaughter in relation to the earthquake because the scientists advised the Civil Protection Agency. This is caused by the large gap between scientific ability for forecasting and forecasting expected from citizens. The similar situations have been repeatedly experienced in Japan, where earthquakes and volcanic eruptions frequently occur. However, we have not been making systematic efforts to fill the gap. In this session, we would like to have fruitful discussions to fill the gap. We are expecting the presentations from not only seismologists and volcanologists but also researchers of the other natural hazards, journalists and people related to civil protection.

U-22	Extreme Weather in Cities	Jun Matsumoto	(Deaprtment of Geography, Tokyo Metropolitan University)
	It is recognized that large cities with a population of several million people are inherently vulnerable to extreme weathers such as torrential rain, giant typhoon, and heat wave. It is argued that the occurrence of weather phenomena tends to increase due to the global warming. Cooperating with related academic societies, the session will focus on the mechanism of extreme weather, its monitoring and prediction methods, effects of urbanization on urban hazards, and social experiments on resilient cities.

U-23	Large Research Projects and their Roadmaps in Earth and Plan	Asahiko Taira	(Center for Deep Earth Exploration Japan Agency for Marine-Earth Science and Technology)
	In March 2010, the Science Council of Japan recommended a table of 43 selected of Japanese large research projects together with a text to explain how the list was constructed. The list includes 7 projects related to earth and planetary science.In late 2010, revision work was carried out involving larger community. In this session, we expect to discuss on long-time perspectives and roadmaps on our future research plans.
