WebNov 30, 2012 · Satellite geodesy has revolutionized the manner in which ice-sheet mass balance is estimated (14, 15).Since 1998, there have been at least 29 ice-sheet mass balance estimates, based variously on the satellite techniques of altimetry, interferometry, and gravimetry ().These estimates, and their respective uncertainties, allow for a … WebNov 1, 2024 · The latter measurement is the cumulative mass balance between September 2024 and 2024 at the mass balance stake closest to each camera (locations in Fig. 1). Since there are up to four stake readings per glacier, we calculate single parameter sets tuned to reproduce all possible combinations of stake readings per glacier.
WebTable 1 lists the major glacier systems in terms of mass balance, cumulative mass loss, and SLE (more details are given in Dataset S1). Sectors with significant SLE include ASE (125 cm), Getz (22 cm), George VI (15 cm), Land/Hull (7 cm), and Fox/Ferrigno (5 cm) in West Antarctica and the Peninsula, but only the ASE may be conducive to marine ... The Cumulative mass balance is the mass of the glacier at a stated time, relative to its mass at some earlier time. Some glaciers have mass balance measurements going back decades, which means that scientists can analyse how mass balance is changing over time. These measurements give us detailed … See more The mass balance of a glacier is a concept critical to all theories of glacier flow and behaviour.
