In an effort to better understand the ocean's role in Greenland's rapid ice loss, researchers must drop scientific probes safely into open water around the island's coast.

NASA has identified three processes responsible for wobbles in Earth's axis of rotation: water mass loss primarily in Greenland, glacial rebound, and mantle convection.

A science team tallies up the many contributions to sea level rise, such as melting ice and warming, expanding oceans.

NASA’s ICESat-2 satellite successfully launched from California on Saturday, embarking on its mission to measure the ice of Earth’s frozen reaches with unprecedented accuracy.

Seven scientists from an upcoming ice-observing satellite mission describe what they are most excited to study once the data are flowing.

ICESat-2 will provide critical observations of how ice sheets, glaciers and sea ice are changing. Here are ten things to know about NASA’s advanced laser altimeter satellite, launching on Sept. 15, 2018.
