Sentences with phrase «sheet under warm water»

Not exact matches

They found that western Antarctica has recently seen warmer, saltier water being driven under the shelf — the part of the ice sheet that sticks out over the ocean (Science, doi.org/xkx).

A new study led by the University of Texas Institute for Geophysics has found that wind over the ocean off the coast of East Antarctica causes warm, deep waters to upwell, circulate under Totten Ice Shelf, and melt the fringes of the East Antarctic ice sheet from below.

While the water under the Antarctic ice is not itself related to global warming, the suprisingly large amount of water, the surprising speed with which it moves, and its effect of «lubricating» the movement of the Antarctic ice, may affect how the ice sheets respond to warming.

Rinse olives under warm water and drain on a paper towel — lined baking sheet.

Other factors would include: — albedo shifts (both from ice > water, and from increased biological activity, and from edge melt revealing more land, and from more old dust coming to the surface...); — direct effect of CO2 on ice (the former weakens the latter); — increasing, and increasingly warm, rain fall on ice; — «stuck» weather systems bringing more and more warm tropical air ever further toward the poles; — melting of sea ice shelf increasing mobility of glaciers; — sea water getting under parts of the ice sheets where the base is below sea level; — melt water lubricating the ice sheet base; — changes in ocean currents -LRB-?)

Warm ocean water plays a significant role in melting glacial ice from below, and a better mapping of Antarctica's and Greenland's landforms beneath the ice suggests that ocean melting of the glacier fronts may play a more significant role than previously thought as the ice sheets retreat (under a global warming scenario).

The rise was caused partly by the simple thermal expansion of sea water under the influence of global warming, and increasingly by the melting of glaciers and ice sheets.

From a combination of climate models, satellite data, and paleoclimate records the scientists conclude that the West Antarctic ice sheet, Arctic ice cover, and regions providing fresh water sources and species habitat are under threat from continued global warming.
