Supporting Information: Abstract We analyzed volume change and mass balance of outlet glaciers of the northern Antarctic • Readme • Text S1 Peninsula over the period 2011 to 2013, using topographic data of high vertical accuracy and great spatial detail, acquired by bistatic radar interferometry of the TanDEM-X/TerraSAR-X satellite formation. The study Correspondence to: area includes glaciers draining into the Larsen-A, Larsen Inlet, and Prince-Gustav-Channel embayments. After H. Rott, collapse of buttressing ice shelves in 1995 the glaciers became tidewater calving glaciers and accelerated,
[email protected] resulting in increased ice export. Downwasting of most glaciers is going on, but at reduced rates compared to À previous years in accordance with deceleration of ice flow. The rate of mass depletion is 4.2 ± 0.4 Gt a 1, with Citation: À1 the largest contribution by Drygalski Glacier amounting to 2.2 ± 0.2 Gt a.
