Description
Summary:This paper proposes an original concept for the complementary use of satellite interferometry and altimetry aimed at generating, geocoding and mosaicking equivalent morphological and rheological models of large European tidewater glaciers (TWGs). Basic methodological aspects and potential glaciological applications, including glacier change detection, ice-divide and ice-coast height measurements, determination of glacier horizontal velocities and ice flux estimation at seaward glacier margins will be discussed. Several new value-added products derived from ERS-1/2 SAR images (1995-1996) and ICESat–GLAS altimetric transects (2003) representing the present state of the largest ice caps and outlet TWGs in the Barents Sea region will be demonstrated.
