Arctic Lows

Record-low sea ice in July 2020 could be further depleted by a low-pressure system that developed over the Arctic Ocean.

Syncing NASA Laser, ESA Radar for a New Look at Sea Ice

With a small nudge to a satellite’s orbit, scientists will soon have simultaneous laser and radar measurements of ice, providing new insights into Earth’s frozen regions.

Johns Hopkins Glacier

While most glaciers in southeast Alaska are losing an astounding amount of ice, this glacier has been relatively stable.

Space Apps COVID-19 Hackathon Brings 15,000 Together Worldwide

Poetry. Mobile apps to promote mental health. Rooftop gardening solutions. Drone delivery for food. These are just some of the projects participants dreamed up in the NASA Space Apps COVID-19 Challenge, a virtual global hackathon aimed at innovations in response to the COVID-19 pandemic.

Breakup Along the Mackenzie River

Each spring, the Canadian Arctic is the site of a fierce battle between water and ice.

Frozen Finland Thaws

After a harsh winter in northern Finland, warm temperatures rapidly melted snow to cause significant flooding.

Ice Arch Persists Despite Warm Arctic

This natural gatekeeper, which prevents sea ice from exiting the Arctic Ocean and drifting southward into Baffin Bay, was still intact in late May 2020.

Mapping Snow on Arctic Sea Ice

First-of-a-kind maps show how the depth of this insulating snow layer changes from month to month.

NASA’s ICESat-2 Measures Arctic Ocean’s Sea Ice Thickness, Snow Cover

Initial results from NASA’s ICESat-2 satellite suggest that Arctic sea ice has thinned by as much as 20 % since the end of the first ICESat mission (2003-2009).

NASA Space Laser Missions Map 16 Years of Ice Sheet Loss

Using the most advanced Earth-observing laser instrument NASA has ever flown in space, scientists have made precise, detailed measurements of how the elevation of the Greenland and Antarctic ice sheets have changed over 16 years.

A-68A Holding it Together

The huge Antarctic iceberg has floated into warmer waters, but it is still mostly intact.

#EarthDayAtHome with NASA

Fifty years ago, on April 22, 1970, people around the world marked the first Earth Day. Thousands gathered to raise awareness about the importance of protecting our beautiful planet for future generations.

NASA Science Keeps the Lights On

Across NASA’s many missions, thousands of scientists, engineers, and other experts and professionals all over the country are doing what they do best, but now from home offices and via video conferencing. With most personnel supporting missions remotely to keep onsite staff at a minimal level in response to COVID-19, the Agency is moving ahead strongly with everything from space exploration to using our technology and innovation to help inform policy makers.

Drifting With Broken Sea Ice

Cracks in the Arctic sea ice are important for satellite-based measurements of the ice’s thickness. They also pose challenges for ship-based researchers participating in the MOSAiC expedition.

Sea Ice Below Normal Despite a Seasonal Bump

Slight recoveries in the extent of sea ice at both poles were not enough to return to long-term normal levels.

Statement on NASA Goddard’s Coronavirus Prep Actions

Goddard has canceled all non-mission-essential visits to its facilities. Goddard also is closing its Visitor Centers at Greenbelt and at Wallops Flight Facility, Virginia.

Antarctica Melts Under Its Hottest Days on Record

Ice caps and glaciers felt the heat as temperatures reached 18.3°C (64.9°F).

Pine Island Glacier’s Newest Iceberg

Iceberg B-49 calved from the Antarctic glacier in February 2020.

Thwaites Glacier Transformed

The amount of ice flowing from the Antarctic glacier has doubled in the span of three decades, and scientists think it could undergo even more dramatic changes in the near future.

Arctic Ice Melt Is Changing Ocean Currents

Using 12 years of satellite data, NASA scientists have measured how the influx of cold, fresh water is affecting the Beaufort Gyre, a major Arctic current.

Widespread Melt on the George VI Ice Shelf

In January 2020, a vast area of melt formed on the surface of the ice shelf west of the Antarctic Peninsula.

NASA’s Operation IceBridge Completes Eleven Years of Polar Surveys

For ten years from 2009 to 2019, the planes of NASA's Operation IceBridge flew above the Arctic and Antarctic, gathering data on the height, flow and change of sea ice, glaciers, and ice sheets.
