Arctic sea ice reached its annual maximum extent on March 17, according to analysis by NASA and the National Snow and Ice Data Center. The 2018 extent reached 5.59 million square miles, only about 23,000 square miles larger...

On Sept. 9th, 2011, Arctic sea ice most likely hit its minimum extent for the year. On Sept. 20th, NASA's Cryosphere Program Manager, Tom Wagner, shared his perspectives on the ice with television audiences across the...

After a record melt season, an Arctic cyclone, and a fascinating fracturing event, Arctic sea ice has reached its maximum extent for the year.<b<b<br/>r/>r/>

We are almost through the Phanerozoic eon! After the Paleozoic and Mesozoic Eras, we get to the Cenozoic era, which is the one we are still living in today. This is the age of mammals, which came to dominate the Earth, and here we also...

Human caused climate change is rapidly melting arctic ice and disrupting ocean currents, which could make Western Europe cooler.

On Sept. 15, 2020, Arctic sea ice reached its annual minimum extent -- the second-lowest on record. This summer, temperatures soared in the Siberian Arctic, and intense fires burned through peatland. The Arctic region is...

For the second straight year, NASA's Operation IceBridge is collaborating with the European Space Agency's CryoVEx program, flying aircraft low over Arctic sea ice while ESA's CryoSat satellite orbits above. In this video, IceBridge...

As of April 6, 2011, crew and scientists with NASA's Operation IceBridge mission have completed eight out of nine planned sea ice flights from Thule, Greeenland, and plan to fly one more from Kangerlussuaq. Michael Studinger, IceBridge...

Researchers aboard the Swedish Icebreaker Oden, as part of the Northwest Passage Project, have found microplastics polluting ice from the Arctic Ocean.

This clip looks at the physical features and climate of Russia's coastal regions.

An underwater “heat blob” from the Atlantic is exacerbating the warming of the Arctic Ocean and contributing to the rapid disappearance of Arctic sea ice

What could go wrong diving in a nuclear submarine in the arctic? For one, we nearly lost our drone.

This clip looks at the physical features, climate and culture of Canada.

The Arctic ecosystem, already under pressure from record ice melts, faces another potential threat in the form of rapid acidification of the ocean, according to an international study published on Monday. Acidification, blamed on the...

The physical and chemical characteristics of ocean waters are discussed including salinity, temperature, density, and pressure. Footage from Maine, the Canadian Maritimes, and the Pacific coast highlight dynamic characteristics of the...
