Ocean stratification and tides control basal melting at the Ross Ice Shelf Grounding Zone

The interactions among ice, ocean, and seafloor in Antarctic grounding zones hold major implications for global sea level rise over the coming century and beyond. Meltwater buoyancy means that grounding zone conditions influence basal boundary layer throughout the entire cavity. Because of the difficulty of direct access, grounding zone ocean environments have been sampled only a handful of times and then usually only as a brief data snapshot. Here, we present ocean data from the Kamb Ice Stream
