The Influence of 5000 year-old and Younger Glacial Mass Variability on Present-day Crustal Rebound in the Antarctic Peninsula
Glacial Maximum is contentious, with estimates ranging from just a few meters to several tens of meters of equivalent eustatic sea level rise. (2) The late Holocene mass budget is also uncertain. Space-based geodesy may provide important data in the coming years for estimating the recent ice mass ba...
