OS008:
Geological, Oceanographic, and Biological Processes of the Western Pacific Convergent Margins and Trenches

Submit an Abstract to this Session



Session ID#: 22908

Session Description:
The western Pacific Ocean is dominated by major convergent plate margins and deep trenches, providing a unique natural laboratory to investigate Earth’s lithosphere-ocean-biosphere interaction, from subduction plate mantle dynamics, to deep ocean circulation and mixing, to microorganisms in the hadal extreme environment. The last few years have witnessed major progress by the international community in multi-disciplinary investigations of the Mariana, Izu-Bonin, Japan, and other western Pacific trench systems. This session will highlight these recent advances, promote inter-disciplinary exchanges, and enhance further international collaborations. We welcome contributions from a wide spectrum of research: (1) Geology, geophysics, and geodynamics of the subduction process and convergent plate margins; (2) Petrology and geochemistry of margin volcanism; (3) Physical and chemical oceanography of the deep ocean circulation, mixing, and interaction with mid- and upper ocean layers; (4) Microbiology of the water column and sediments; and (5) Interaction between geological, oceanographic, and biological processes.
