Sentences with phrase «ice sheet elevation»

These increases and losses depend on ice sheet elevation and region.

Measurements of ice sheet elevation changes indicate the volume of ice lost, and hence the contribution to sea levels, he tells Carbon Brief.

ICESat - 2's laser instrument can measure the rate of ice sheet elevation change over the course of a year to within two - tenths of an inch (0.4 centimeters), allowing scientists to see when and where ice is growing thicker as snow accumulates, or getting thinner from melting.

A team of scientists from the UK Centre for Polar Observation and Modelling, led by researchers at the University of Leeds, have produced the first complete assessment of Antarctic ice sheet elevation change.

For several of the key ice sheets the elevation is below sea level for considerable distances, so grounding line retreat dynamics have different forcings, such as mid-level «warm» water penetration.

Although CryoSat - 2 is designed to measure changes in the ice sheet elevation, these can be translated into horizontal motion at the grounding line using knowledge of the glacier and sea floor geometry and the Archimedes principle of buoyancy — which relates the thickness of floating ice to the height of its surface.

The project maps the ice sheet elevation and thickness in never - before - visited regions, extracted ice cores to look at the past 2000 years of climate, and investigated ongoing ice motion and climate change effects in East Antarctica.
