These increases and losses depend on ice sheet elevation and region. (sciencedaily.com)
Measurements of ice sheet elevation changes indicate the volume of ice lost, and hence the contribution to sea levels, he tells Carbon Brief. (carbonbrief.org)
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. (jpl.nasa.gov)
