Future rates of sea-level rise depend strongly on the response of grounded ice to changing conditions at the ice-ocean interface in vulnerable marine-terminating basins, such as West Antarctica, many outlet glaciers in East Antarctica and Greenland, and large tidewater glaciers at high latitudes. Ocean forcing is constrained through measurements of physical ocean properties and analysis of circulation patterns at local, regional, and global scales. Grounded ice response depends on the physical processes governing basal melt, ice fracture and calving, and dynamic perturbations in ice flow. We invite contributions to this session that advance community understanding of glacial change due to processes at the ice-ocean interface by addressing any aspect of forcing or response at or near this boundary. We welcome all relevant methodologies, including field measurements, remotely sensed observations, and numerical modeling, and particularly encourage multi-method and multi-discipline studies.
