Meltwater In Crevasses In Greenland

NASA's annual survey of changes in Arctic ice cover greatly expanded its reach in a series of flights that wrapped up on May 12, 2017.

On July 7, 2021, NASA sent two robotic explorers to the Arctic to collect sea surface temperature data and improve estimates of ocean temperatures in that region.

Thinning of rift-healing slush is identified as a major cause of iceberg calving events

For decades, scientists have assumed that losses in Arctic sea ice cover allow for the formation of more clouds near the ocean's surface.

Sea ice in the Arctic appears to have hit its annual minimum extent on Sept. 16, after waning in the 2021 Northern Hemisphere spring and summer. The summertime extent is the 12th-lowest in the satellite record, according to scientists at the NASA-supported National Snow and Ice Data Center and NASA.

Ice Persists In The Northwest Passage

For centuries, explorers have tested the icy waters of the Arctic, looking for sea routes through the cluster of islands north of mainland Canada.

As the North Pole, the Arctic Ocean, and the surrounding Arctic land warm rapidly, scientists are racing to understand the warming's effects on Arctic ecosystems.

Sea ice in the Arctic appears to have hit its annual maximum extent after growing through the fall and winter.

Earth Is Losing Ice At A Record Rate

A research team - the first to carry out a survey of global ice loss using satellite data - has discovered that the rate at which ice is disappearing across the planet is speeding up.

New Depth Map Of The Arctic Ocean

An international team of researchers has published the most detailed submarine map of the Artic Ocean.

In the early 1900s, Ernest Shackleton attempted to travel across Antarctica, but as they neared the continent his ship became stuck in an pack of sea ice and was slowly crushed before it reached the landmass.

Scientists using data from the Copernicus Sentinel-5P satellite have noticed a strong reduction of ozone concentrations over the Arctic. Unusual atmospheric conditions, including freezing temperatures in the stratosphere, have led ozone levels to plummet - causing a 'mini-hole' in the ozone layer.

A major ocean current in the Arctic is faster and more turbulent as a result of rapid sea ice melt, a new study from NASA shows.

Designed to collect data during the years between NASA's two Ice, Cloud, and land Elevation Satellites, ICESat and ICESat-2, IceBridge made its final polar flight in November 2019, one year after ICESat-2's successful launch.

The skies were clear, the winds were low, and the lasers aligned.

As millions of people around the world marched for urgent action on climate change ahead of this week's UN Climate Action Summit, an icebreaker set sail from Norway to spend a year drifting in the Arctic sea ice.

The extent of Arctic sea ice at the end of this summer was effectively tied with 2007 and 2016 for second lowest since modern record keeping began in the late 1970s.

New NASA-funded research has discovered that Arctic permafrost's expected gradual thawing and the associated release of greenhouse gases to the atmosphere may actually be sped up by instances of a relatively little known process called abrupt thawing.

To study the most extreme objects in the Universe, astronomers sometimes have to go to some extreme places themselves.

The Dark Zone of Greenland ice sheet is a large continuous region on the western flank of the ice sheet; it is some 400 kilometers wide stretching about 100 kilometres up from the margin of the ice.
