Greenland mass variation since 2002
WebJul 8, 2024 · Antarctic glaciers flow from the inland to the shore, forming an ice shelf or glacier tongue, and are eventually discharged into the ocean. As the motion of the glacier is closely related to the seaward ice flux, ice flow velocity is an important indicator of global climate change and sea level rise [1,2,3].The flow velocity of a glacier changes due to … WebJan 1, 2007 · Accelerated warming of the Arctic is well-documented, and mass loss of the Greenland ice sheet has accelerated in recent decades due to increases in both ice discharge and surface meltwater runoff. Greenland ice sheet melt has been marked by two major melt events since 2000—one in 2002 and another in 2012. The summer of 2012 …

WebApr 22, 2024 · In the last several decades, the Greenland Ice Sheet (GIS) has lost mass to the ocean (1–5).The mass loss has been quantified by three independent techniques using changes in ice volume (6, 7), time-variable gravity (), and input versus output fluxes or mass budget method (1, 2, 4, 9–11), for the time period 1992–2016 or 2002–2016.The mass … WebOct 4, 2024 · Greenland’s ice mass loss has been accelerating recently. Using satellite Earth-gravity and regional climate model data, we show that the acceleration rate of Greenland ice mass loss from...
WebNov 19, 2012 · These measurements have shown both strong variations among seasons and strong decadal variations in the inferred mass change rates (6, 12). Coincident with these observations since 2002, the Gravity Recovery and Climate Experiment (GRACE) dual-satellite mission has been sensing the Earth’s geopotential field continuously. WebThe Greenland cryosphere is undergoing rapid changes, and these are documented by remote sensing from space. In this paper, an inversion scheme is used to derive mass changes from gravity changes observed by GRACE, and to derive the mean annual mass loss for the Greenland Ice Sheet, which is estimated to be 204 Gt/yr for the period 2002 …
WebNov 1, 2024 · If the rate of Greenland ice loss were to remain at its 2012 to 2016 average of 247 gigatonnes (272 gigatons) per year, which is an annual loss of about 0.01% of the total mass of the ice sheet, it would take another 10,000 years for all Greenland’s ice to melt. WebJan 3, 2013 · The seasonal variation in the SLR estimates is primarily from hydrological mass variations since an atmosphere–ocean de-aliasing model has been applied. [26] The ice mass loss rates for Greenland and Antarctica were obtained from the surface density changes calculated from the GRACE monthly estimates for the gravity field coefficients …
