Ice-Ocean-Seafloor Interactions and Climate Dynamics Across Timescales
Session ID#: 259407
Session Description:
This session brings together studies investigating the dynamic interactions between ice sheets, oceans, and the seafloor across a range of temporal and spatial scales. Polar and subpolar regions are key components of the climate system, with changes in ice sheet extent, ocean circulation, and seafloor morphology playing critical roles in modulating global climate, sea level, and deep water formation. We welcome multidisciplinary contributions that draw on geological, geophysical, geochemical, and proxy records from both hemispheres to examine past and present cryosphere-ocean-seafloor processes. These include studies of ice sheet dynamics from ice-proximal to deep-sea settings, reconstructions of high-latitude climate variability, oceanic responses to glaciation and deglaciation, and the influence of bathymetric evolution on circulation pathways. Submissions that integrate observations, modeling, and multi-proxy approaches to explore climate transitions, teleconnections, and feedback mechanisms are especially encouraged. This session aims to foster cross-disciplinary dialogue on the coupled evolution of the cryosphere, ocean, and solid Earth, offering insights into the processes driving climate change and the interpretation of past environmental archives.
