There are two primary causes of global mean sea level rise -- added water from melting ice sheets and glaciers, and the expansion of sea water as it warms. The melting of Antarctica's ice sheet is currently responsible for 20-25% of global sea level rise.

As part of the EU project "Beyond EPICA - Oldest Ice", experts from 14 institutions located in 10 European countries have spent three years combing the Antarctic ice sheet to find the ideal location to retrieve the oldest ice core on the Earth

A recently-launched satellite mission has captured precision data on the elevation of the Antarctic ice sheet proving a valuable addition to monitoring efforts in the region, according to work published this week in The Cryosphere.

A kite-blown science expedition to the interior of Antarctica has made the most southerly positioning fixes yet made with Europe's Galileo satellite navigation system.

A gigantic cavity -- two-thirds the area of Manhattan and almost 1,000 feet (300 meters) tall -- growing at the bottom of Thwaites Glacier in West Antarctica is one of several disturbing discoveries reported in a new NASA-led study of the disintegrating glacier.

It was five years ago this month that ESA's GOCE gravity-mapping satellite finally gave way to gravity, but its results are still yielding buried treasure - giving a new view of the remnants of lost continents hidden deep under the ice sheet of Antarctica.

Operation IceBridge, NASA's longest-running aerial survey of polar ice, flew over the northern Antarctic Peninsula on Oct. 16, 2018.

IceBridge's Airborne Topographic Mapper instrument, or ATM, has two lasers that shoot thousands of pulses of light per second in a circular motion that, combined with the plane's forward motion, result in spiral patterns of height measurements over Earth's surface.

Sentinel-3B's very first sight was the sunset over the Weddell Sea, just off the coast of Antarctica.

NASA's Tracking and Data Relay Satellites (TDRS) don't just enable data from spacecraft to reach Earth - they provide internet and even telemedicine to researchers at the South Pole.

The East Antarctic Ice Sheet locks away enough water to raise sea level an estimated 53 meters (174 feet), more than any other ice sheet on the planet.

The Copernicus Sentinel-1 mission gives us 'radar vision' over part of Antarctica's third-largest island, Thurston Island.

A new NASA study adds evidence that a geothermal heat source called a mantle plume lies deep below Antarctica's Marie Byrd Land, explaining some of the melting that creates lakes and rivers under the ice sheet.

New ESA Crew and Research in Antarctica

The Concordia research station in Antarctica is a place of extremes: for nine months no supplies can be delivered, the nearest living beings are 600 km away at the Russian Vostok station, and the Sun does not rise above the horizon for four months in the winter.

A NASA study has located the Antarctic glaciers that accelerated the fastest between 2008 and 2014 and finds that the most likely cause of their speedup is an observed influx of warm water into the bay where they're located.

Larsen C, a floating platform of glacial ice on the east side of the Antarctic Peninsula, is the fourth largest ice shelf ringing Earth's southernmost continent.

Second NASA Balloon Flight in Antarctica

The second of three missions as part of NASA's Antarctica Long Duration Balloon Flight Campaign was successfully launched at 8:10 a.m. EDT, Dec. 2.

Two new studies by researchers at NASA and the University of California, Irvine (UCI), detect the fastest ongoing rates of glacier retreat ever observed in West Antarctica and offer an unprecedented direct view of intense ice melting from the floating undersides of glaciers.

Year 8 For Operation IceBridge

At the southern end of the Earth, a NASA plane carrying a team of scientists and a sophisticated instrument suite to study ice is returning to surveying Antarctica.

A trip to the Red Planet begins long in advance of liftoff.
