We constrain viscoelastic Earth rheology and recent ice-mass change in the northern Marguerite Bay region of the Antarctic Peninsula. Global Positioning System (GPS) time series from Rothera and San Martin stations show bedrock uplift range of∼−0.81.8mm/year over 19992005 and 20162020 but ∼3.56.0mm/...
