The Science Plan is intended to guide multidisciplinary international collaboration on scientific ocean drilling during the period 2013-2023. Crafted on behalf of earth, ocean, atmospheric, and life IODP Science scientists at the request of Plan 2013-2023 science funding agencies from 24 nations , representing approximately 75% of the world's economy. IODP also builds intellectual capacity through the promotion of international collaboration, education, and training. PDF versions @ http://www.iodp.org/about-iodp/iodp-science-plan-2013-2023

T-Limit of the Deep Biosphere off Muroto High heat flow regimes in this area result in temperatures of ~130°C at the sediment /basement interface (1210 mbsf) encompassing the biotic/abiotic transition zone.

The ECORD Council theme of the decadal Science endorses the finding of the limited Plan. number of focused expeditions with a strong focus on biosphere The Forum supports a Emerging frontiers topics but emphasizes that workshop-based approach to: the submission of drilling proposals 1.) identify new/broader follows a bottom-up approach. components of the Opportunities international scientific However, the ECORD Council community to develop recommends that ECORD informs “Biosphere Frontier” drilling the scientific community that the proposals, and ECORD Evaluation has identified that the deep biosphere theme is 2.) build that biosphere theme not covered as well as the other more strongly into the current IODP themes and, therefore flow of IODP proposals. encourages the community to develop more deep biosphere related activities to fill this gap.

Hydrology Lead: Alica Wilson Theme We choose this location so that we can build Microbiology Lead: Maija Raudsepp on the already existing geochemical data from Leg 182, and because the GAB is Other proponents: considered a modern analogue of Mesozoic carbonate systems, not only in V.

The tantalizing possibility is that we will gain an unprecedented glimpse into the Pre-proposal microbial and organic geochemical Site survey mature processes that are responsible for the formation of a large portion of the world’s hydrocarbon resources , as well as determine the role of saline groundwater flow in carbonate diagenesis in continental margin environments.
