Greenland mass ice balance
WebSep 4, 2024 · Since the 1990s, mass loss from the Greenland ice sheet (GrIS) has significantly accelerated due to increased glacial discharge and decreased surface mass balance (SMB), the latter representing the difference between mass gains from snowfall and mass losses from meltwater runoff and sublimation.While glacial discharge strongly … WebApr 12, 2024 · Abstract.

WebThe accumulated mass drives ice deformational flow resulting in ~239 km3 iceberg discharge with ~32 km3 basal melting (Reeh et al. 1999). Between 200-550 km3 or approximately half of the annual mass input is lost by freshwater discharge (Zwally and Giovinetto, 2000; Box et al., 2004), making Greenland unique as compared to the other … WebIn this paper, we present a time series of the annual surface mass balance (SMB) of the Greenland ice sheet for the period 1866–2005. Values of SMB are quoted with respect to the average value for the 1961–90 climatological normal period. In addition, we report on how the spatial patterns of SMB vary over specified historic time intervals.

WebMar 9, 2011 · We find annual mass loss estimates of the Greenland ice sheet in the range of 191 ± 23 Gt yr−1 to 240 ± 28 Gt yr−1 for the period October 2003 to March 2008. These results are in good agreement with several other studies of the Greenland ice sheet mass balance, based on different remote-sensing techniques.
WebNov 16, 2024 · The total mass balance for 2024-21 is a loss of around 166Gt of ice from Greenland – close to the average ice lost each year for the period 1986-2024. This means that, from 1 September 1986 to 31 August 2024, we calculate the Greenland Ice Sheet has lost approximately 5,500Gt of ice.
