Dynamic Mass Loss from Greenland’s Marine-Terminating Peripheral Glaciers
Summary & Purpose
Balance has decreased rapidly over the last two decades, exceeding mass loss from the Greenland and Antarctic ice sheets. In Greenland, peripheral glaciers and ice caps (GICs) cover only ~5% of Greenland’s area but contributed ~20% of the island’s ice mass loss between 2000-18. Although Greenland GIC mass loss due to surface meltwater runoff has been estimated using atmospheric models, mass loss due to changes in ice discharge into oceans (i.e., dynamic mass loss) remains unquantified. We use the flux gate method to estimate discharge from Greenland’s 585 marine-terminating peripheral glaciers between 1985-2018, and compute dynamic mass loss as the discharge anomaly relative to the 1985-98 period. Here we provide the coordinates for the flux gates used to construct discharge time series for these glaciers.

Single Dataset or Series?
*.shp, *.shx, *.dbf, *.prj
Each shapefile contains the coordinates for the flux gate used to estimate discharge from one of Greenland's peripheral marine-terminating glaciers. There are three accompanying files (.shx, .dbf, and .prj) for each glacier. The glacier coordinates were manually delineated to span the glacier within ~2 km of the terminus, oriented approximately perpendicular to the flow direction. The X and Y coordinates are provided in the Greenland Polar Stereo reference frame (EPSG:3413).
