Session Proposal: Seafloor/Sub-Seafloor Processes in Polar Regions (AGU25)

OS023
Seafloor/Sub-Seafloor Processes in Polar Regions

Session ID#: 247612

Session Description:
The seafloor in both Arctic and Antarctic oceans is the science frontier for understanding how this planet and its environments are shaped by ice. This session is inspired by the recent discoveries during R/V Nathaniel B. Palmer NBP25-01 Expedition in the western Ross Sea seafloor, Antarctica, which has shed new light on young (LGM to recent) seafloor volcanic processes, their interactions with ice sheets, fluid expulsion and methane flux. We especially welcome multidisciplinary and transdisciplinary contributions studies addressing a broad range of seafloor/sub-seafloor processes in polar oceans.  Topics can range, but not limited to: geological processes within seafloor and subseafloor in polar regions, deep biosphere facilitated by the geological processes, ice sheet-seafloor interactions, glaciovolcanology in marine settings, groundwater and hydrocarbon seepage, offshore polar gas hydrates, studies of Earth regarding ocean worlds’ analogue to icy planets, and advancement in marine technologies that enable progress in polar marine sciences.
