Totten Glacier, the primary ice discharger of East Antarctica, contains 3.85 m sea level rise equivalent ice mass (SLRe) and has displayed ocean-driven dynamic change since at least the early 2000s. We project Totten’s evolution through 2100 in a fully coupled ice-ocean model, forced at the ocean boundaries with anomalies in CMIP6 projected temperature, salinity, and velocity. Consistent with previous studies, the Antarctic Slope Current continues to modulate warm water inflow towards Totten in future...
