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 budget method is the only one that provides information about the physical processes controlling the mass loss, i.e., the partitioning between surface mass balance (SMB) processes (accumulation minus runoff and other forms of ablation However, it is likely that the relatively high end of season SMB will mean a zero or close-to-zero total mass budget this year, as last year. The period 2003-2011 has seen ice sheet losses on Greenland averaging 234bn tonnes each year. The neutral mass change in the last two years does not – and cannot – begin to compensate for these losses.

The figures are based on calculations using DMI's operational ocean and sea ice model HYCOM-CICE. Marine-terminating glaciers are the outlets via which the Greenland ice sheet discharges ice mass to the ocean. When in balance, the rate of iceberg calving (by area) is equalized by the seaward flow of the ice (see the essay on Greenland Ice Sheet Surface Velocity: New Data Sets, 2015 Arctic Report Card for further information on the velocity of these glaciers). 2016-03-01 For comparing recent changes in Greenland tempera-tures with GrIS mass balance, surface mass balance (snow accumulation minus surface meltwater runoff) and solid-ice discharge variations, we use the recently-published dataset of Mouginot et al.

The period 2003-2011 has seen ice sheet losses on Greenland averaging 234bn tonnes each year. The neutral mass change in the last two years does not – and cannot – begin to compensate for these losses. Almost all of the ice loss was due to changes in surface mass budget, with thinning found virtually everywhere.

Danish Meteorological Institute (DMI) has for the second year shown record ice growth across the Greenland Ice Sheet, but NASA shows a 281 gigaton loss, oops

Previous uses of the DMI graph includes 'Greenland Ice Growth Ahead Of Last Year’s Record Pace' (Oct 2017) which seems oddly careful to specify that DMI does show surface mass balance given that it goes on to talk of 'criminals in the press and academia'; 'Record Greenland Ice Growth Continues' (Sep 2017); 'Scientists Discover That Their Imaginary Greenland Meltdown Is Not Having Any Effect Marine-terminating glaciers are the outlets via which the Greenland ice sheet discharges ice mass to the ocean. When in balance, the rate of iceberg calving (by area) is equalized by the seaward flow of the ice (see the essay on Greenland Ice Sheet Surface Velocity: New Data Sets, 2015 Arctic Report Card for further information on the velocity of these glaciers).

Se hela listan på arctic.noaa.gov At DMI, we use a weather forecasting model to calculate how much Greenland ice is gained and lost every day.

However, it is likely that the relatively high end of season SMB will mean a zero or close-to-zero total mass budget this year, as last year. The period 2003-2011 has seen ice sheet losses on Greenland averaging 234bn tonnes each year. The neutral mass change in the last two years does not – and cannot – begin to compensate for these losses.

And for the next 5 to 10 days it looks like, - no melt, - below average precipitation, - SMB balance year to date a bit more below average. The reason I’m pointing this is out is that the largest loss of ice in Greenland this year was 11 billion tons. Journalists like to put intense focus on a single day or week’s worth of melting in Greenland, yet disregard large mass gains in surface mass balance that occur outside of “melt season.”. Figure 5.
