The shelves slow and stabilize the glaciers behind them, but they are succumbing to a hidden force: Deep, warming ocean currents are melting the ice from beneath.

A new study shows that as a glacier's ice melts, bubbles of pressurized ancient air escape into the water, leading to noise levels even louder than those beneath rain - pounded seas heaving with 6 - meter waves.

The results highlight how the interaction between ocean conditions and the bedrock beneath a glacier can influence the frozen mass, helping scientists better predict future Antarctica ice loss and global sea level rise.

However, Khazendar and Scheuchl said, researchers need more information on the shape of the bedrock and seafloor beneath the ice, as well as more data on ocean circulation and temperatures, to be able to better project how much ice these glaciers will contribute to the ocean in a changing climate.

Now, Bindschadler and other researchers are heading out to fetch some of the first temperature data from under the Pine Island Glacier ice shelf, the outlet of one of the largest and fastest moving glaciers in Antarctica, in hopes of understanding what is happening beneath it.

As glaciers and ice caps melt, Louisiana is losing land to the sea and barrier islands are gradually slipping beneath the watery surface, drowned by a slowly rising tide, a process suggested by the cover photo.

The silent glacier rested in the valley beneath us, with ice stretching back through the valley and piling up the mountainsides, eventually melting into the flat white of the February clouds.

As the surface ice begins to melt, some of the water filters down through cracks in the glacier, lubricating the surface between the glacier and the rock beneath it.

Now, two new studies conducted by researchers at NASA and the University of California, Irvine, have revealed that glaciers in West Antarctica are retreating at an unprecedented rate due to warm water circulating beneath the ice shelf.

Two new studies conducted by researchers at NASA and the University of California, Irvine, have revealed that glaciers in West Antarctica are retreating at an unprecedented rate due to warm water circulating beneath the ice shelf.

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).

But scientists increasingly attribute much of the observed grounding line retreat — particularly in West Antarctica — to the influence of warmer ocean water seeping beneath the ice shelves and lapping against the bases of glaciers, melting the ice from the bottom up.

The rapid melting of Kangerdlugssuaq glacier has produced a special category of earthquake known as a glacialquake.1, 3 Once thought to occur when glacial ice strikes solid earth beneath it, glacialquakes are now attributed to lurching that occurs when parts of the glacier break off (calve) into the ocean.4, 5

Cryosphere All regions on and beneath the surface of the Earth and ocean where water is in solid form, including sea ice, lake ice, river ice, snow cover, glaciers and ice sheets, and frozen ground (which includes permafrost).

«The glaciers of Greenland are likely to retreat faster and further inland than anticipated — and for much longer — according to this very different topography we've discovered beneath the ice,» Morlighem said.

Glaciers during the last ice age were so thick and heavy that their weight caused the land immediately beneath them to sink, while the land at the edges of the glacieGlaciers during the last ice age were so thick and heavy that their weight caused the land immediately beneath them to sink, while the land at the edges of the glaciersglaciers rose.
