The northern Antarctic Peninsula (nAP, < 66 S) is one of the most rapidly changing glaciated regions on earth, yet the spatial patterns of its ice mass loss at the glacier basin scale have to date been poorly documented. We use satellite laser altimetry and satellite stereo-image topography span- ning 2001-2010, but primarily 2003-2008, to map ice eleva- tion change and infer mass changes for 33 glacier basins cov- ering the mainland and most large islands in the nAP. Rates of ice volume and ice mass change are 27.7± 8.6 km 3 a 1 and 24.9±7.8 Gt a 1 , equal to 0.73 m a 1 w.e. for the study area. Mass loss is the highest for eastern glaciers affected by major ice shelf collapses in 1995 and 2002, where twelve glaciers account for 60 % of the total imbalance. However, losses at smaller rates occur throughout the nAP, at both high and low elevation, despite increased snow accumula- tion along the western coast and ridge crest. We interpret the widespread mass loss to be driven by decades of ice front re- treats on both sides of the nAP, and extended throughout the ice sheet due to the propagation of kinematic waves triggered at the fronts into the interior.
