Zur LanganzeigeZusammenfassung
This product contains 170 Greenland glacier calving front positions from the following glaciers: Hagen Bræ, Helheim Glacier, Kangiata Nunaata Sermia, Nioghalvfjerdsbræ, Tracy Glacier and Zachariae Isstrøm. The glacier calving front positions have been manually derived from multispectral Landsat-8 imagery and are stored in an ESRI shapefile format using the WGS 84 / NSIDC Sea Ice Polar Stereographic North (EPSG:3413) Coordinate Reference System. Hagen Bræ covers the years 1985-2013 and Nioghalvfjerdsbræ between 1985-1994 on a nearly yearly basis. For Zachariae Isstrøm, calving fronts are featured every year between 1985-1993. With two calving fronts per year, except for 1984, Helheim Glacier involves the years 1979-1988. Irregular coverage with up to 3 calving front locations in one year show Kangiata Nunaata Sermia between 1978-2012 and Tracy Glacier covering the years 1973-2013.
