Antarctica’s George VI Ice Shelf experienced record melting during the 2019-2020 summer season.

Antarctica experienced a sixfold increase in yearly ice mass loss between 1979 and 2017.
New detailed NASA maps of ice velocity and elevation show that a group of glaciers spanning one-eighth of East Antarctica’s coast have begun to lose ice over the past decade, hinting at widespread changes in the ocean.
The Thermal Infrared Sensor (TIRS) on Landsat 8 captured a new snap of the 2,240-square-mile iceberg that split off from the Antarctic Peninsula’s Larsen C ice shelf on July 10-12.
The iceberg is about the size of Delaware.

The Landsat program, a joint venture between NASA and the U.S. Geological Survey (USGS), has been observing Earth for over 50 years, collecting breathtaking imagery
The Brunt Ice Shelf lost a large wedge of floating ice, the third sizeable iceberg to calve from the shelf in recent years. The TIRS instrument on Landsat 9 captured false-color images of the calving.
Landsat satellites have begun regularly acquiring images of ice at the poles during the winter, with enlightening results.
New research shows that while some Antarctic ice shelves have been thinning since at least the 1970s, widespread thinning accelerated in the 1990s.
“While many previous studies have reported ongoing ice shelf thinning around Antarctica since the 1990s, we didn’t previously know that a lot of it started

This February marks the 10th anniversary of the launch of Landsat 8, launched by NASA in 2013 and operated by the US Geological Survey.
An international team of researchers has combined satellite imagery and climate and ocean records to obtain the most detailed understanding yet of how the West Antarctic Ice Sheet – which contains enough ice to raise global sea level by 3.3 metres – is responding to climate change.
New research uses Landsat observations and advanced computing to chronicle wetlands lost (and found) around the globe.
Landsat satellites have been reliably returning images of Earth’s land surface for fifty years, providing novel insights about the planet we call home.
Despite the rapid melting of ice in many parts of Antarctica during the second half of the 20th century, researchers have found that the floating ice shelves which skirt the eastern Antarctic Peninsula have undergone sustained advance over the past 20 years.
Satellites have helped show that strong tidal activity may facilitate water-induced fracturing, or hydrofracturing, where land ice transitions to floating ice shelf and cause the meltwater lake to drain quickly, often in as little as several days.
