Most sea - level rise comes from water and ice moving from land into the ocean, but the melting of floating ice causes a small amount of sea - level rise, too.

«This correlation tells us this is the same water and that this is what's causing the melting of the glacier, which could influence sea level rise,» said Muenchow, an associate professor of oceanography in UD's School of Marine Science and Policy, which is housed in the College of Earth, Ocean, and Environment (CEOE).

The hope is that the cables could reveal secrets about what's happening underneath the ice sheets, especially about melting at the so - called grounding line, the place where the bottom of an ice sheet meets the slightly warmer ocean.

Recording these temperatures continuously can help scientists develop a detailed picture of the physics by which the ocean melts the ice shelves from below, says oceanographer Laurence Padman of Earth & Space Research in Corvallis, Oregon.

But as you can imagine, in this day of budget cutting in countries around the world, Antarctic science programs are being sliced, so there is this concern that it's a place also that could be kind of forgotten in the not so distant future, and that would be a tragedy because as that ice melts and if it can specifically continues to melt at the rate it is now, that will impact all of the world's oceans.

Some glaciers on the perimeter of West Antarctica are receiving increased heat from deep, warm ocean currents, which melt ice from the grounding line, releasing the brake and causing the glaciers to flow and shed icebergs into the ocean more quickly.
