Sentences with phrase «calving flux»

Higher calving flux indicates higher velocities (Van Den Broecke et al, 2009).

In a paper I published in 1990 we established the calving flux of the Jakoshavns Isbrae, the most productive glacier in Greenland at 40 cubic kilometers per year, it is retreating after 40 years of balance.

The glacier's calving flux has * averaged * 4 cubic kilometers / year since the onset of retreat with a maximum of 7 kilometers / year in the early 2000s.

The only similar glacier on the Northern Icefield, is the San Rafael (which used to have a high calving flux and velocity until it started receding into shallow water).

A recent analysis of ice shelves across Antarctica has shown that basal melt rates are around 1325 ± 235 gigatonnes per year, with an additional calving flux of 1089 ± 139 gigatonnes per year.

Not exact matches

Freshwater flux from Greenland is composed of melt runoff from ice and tundra runoff as well as ice discharge («calving» of icebergs).

If I may add one more speculative question: are the portions of glacial sheets formed during periods of high ice flux less stable, and more prone to calving, than those formed during slow flux?

The mass balance at the calving front is the sum of the ice flux from upglacier, the rate of melting above and below the waterline and the iceberg - calving rate.

Hence the above velocity map of the glacier will indicate higher average velocities in the quadrants with the highest calving volume flux.

Or what if stronger tides increased glacial flow or calving at the coasts, or tidal currents openned up gaps in sea ice covering by piling sea ice against islands, thus affecting albedo and surface heat fluxes?
