NASA goes to sea to take an up-close look at how changing conditions in the Arctic are affecting the ocean’s chemistry and ecosystems.
Iceberg B-09B -- itself nearly the size of Rhode Island -- collided with an Antarctic glacier last month, forming a new berg still larger than the European nation of Luxembourg.
ICESat has provided a critical look at ice thickness at Earth's polar regions over the course of its seven-year life. That mission is now coming to an end.
In 2007, the Arctic lost a massive amount of thick, multiyear sea ice, contributing to that year's record-low extent of Arctic sea ice.
A new NASA study finds undersea melting of glaciers in west Greenland due to ocean warming is playing a major, previously overlooked, role in their evolution.
New NASA-led research shows that the melt season for Arctic sea ice has lengthened by an average of 20 days over the span of 28 years.
The latest data reveal that Antarctica is losing ice at an accelerating rate, while surface melting recently has decreased. How is this possible?
Taking a new look at how everyday human behaviors are affecting the Arctic, a major regulator of the planet's climate.
A new study using NASA satellite data finds East Antarctica's ice sheet may not be as stable as previously thought. The results may have major climate implications.
This year's satellite measurements show the area of the Arctic Ocean covered by floating ice was the third lowest since satellite measurements were first made in 1979.
Researchers have used NASA's ICESat to compose the most comprehensive picture of changing glaciers along the coast of the Greenland and Antarctic ice sheets.
In 2002, NASA created a video tour of Earth's frozen regions using satellite data. This year, NASA visualizers are taking viewers on a return trip to see what's changed over the years.
Even as global air and ocean temperatures march upward, the extent of the sea ice around the southern continent isn’t decreasing. In fact, it's increasing and scientists want to know why.
NASA and other research scientists recently combined the high spatial coverage from satellites with a longer record from Cold War submarines to piece together a history of ice thickness that spans close to 50 years.
Researchers using space-based lasers have created the most comprehensive inventory of lakes that actively drain or fill under Antarctica's ice.
Arctic sea ice thinned dramatically between the winters of 2004 and 2008, with thin seasonal ice replacing thick older ice as the dominant type for the first time on record.
A team of scientists embark this week on a two-month expedition to Greenland and Iceland to use a pair of new airborne radars that can help monitor climate change.
A narrow ice bridge connecting the last remnants of the northern part of Antarctica’s Wilkins Ice Shelf broke apart in early April 2009.
Polar scientists believe Antarctica's Pine Island Glacier to be thinning because of warm ocean waters below.
The latest Arctic sea ice data show that the decade-long trend of shrinking sea ice cover is continuing.
