  • Area of drainage basin in 103 km2, average SMB for 1979–2008 with 1-σ uncertainty in billions of tons per year, average ice discharge (D) for 1979–1990, 1989–2000, 1999–2010, and 2009–2017 with 1-σ uncertainty in billions of tons per year , cumulative mass gain (M) in billions of tons for 1979–2017, SLR (millimeters) for 1979–2017, and SLR equivalent for each basin (centimeters). Source of ice thickness: [1] Bedmap-2, [2] Mass Conservation, [3] Griggs and Bamber DEM, [4] Balance flux and speed, and [5] Ice floatation from TDX DEM.
