Abstracts are being sought for Union session Discoveries from Subseafloor Sampling and Monitoring using Scientific Ocean Drilling at the JpGU - AGU Joint Meeting, Chiba, Japan, May 20-25 2017. The submission deadline is February 16 at 17:00 Japan Standard Time.

 The Earth is an ocean planet. We at times feel the environmental changes or geohazards that affect our lives. These are signs of the complex Earth behavior, for which oceans and the underlying oceanic lithospheres play key roles. Scientific ocean drilling uniquely delivers samples and data from boreholes to be scrutinized and synthesized across disciplines in geo-biosciences, and to validate the hypotheses that predict our future state. This session will highlight recent achievements and future prospectus, especially those using "Chikyu."

Session technical scope: The sediments and lithosphere beneath the seafloor hold invaluable information on the history and dynamics of climatic, biological, chemical, and geological changes over 100 million years. Scientific deep-sea drilling (currently through the International Ocean Discovery Program, IODP) has been providing unique opportunities among various geoscientific methods to discover their histories and dynamics over time scales covering climatic, geohazards and mantle convection processes. Such knowledge is also recognized as important for projecting the current Earth system into the near and far future, particularly involving the effects of anthropological interventions. This session invites contributions that focus on the perspectives of recent new discovery geoscientific discoveries based on ocean floor drilling and borehole observatory records, and further on visions of new paradigms of ocean science. The session will cover mainly the four scientific themes in the current IODP science plan of: (1) Climate and ocean changes, (2) Biospheres frontiers, (3) Earth connections, and (4) Earth in motion. Also, we encourage contributions relating science to societal relevance, such as environmental and geohazard problems facing the society today.

This first Japan Geoscience Union - American Geophysical Union Joint Meeting is particularly important for building collaborations among the geoscience community in Asia, Oceania, and the western Pacific. The meeting will take place at the Makuhari International Conference Hall / Exhibition Center, APA Hotel Resort Tokyo Bay Makuhari in Chiba, Japan.
