Last spring, NASA’s Operation IceBridge flew over one of Greenland’s earliest melt seasons on record. This year, the melt is progressing more typically, despite warm temperatures in the Arctic. Brooke Medley reflects on...

Former astronaut and climate scientist Dr. Piers Sellers visits Thule, Greenland, one of the home bases for Operation IceBridge’s spring Arctic campaign. IceBridge is a 10-year airborne science mission measuring polar ice with a range of...

2021 saw the hottest ocean temperatures ever recorded, adding to previous records in 2018 and 2019.

The transpolar drift (purple arrows) is a dominant circulation feature in the Arctic Ocean that carries freshwater runoff (red arrows) from rivers in Russia across the North Pole and south towards Greenland. Under changing atmospheric...

Operación Icebridge es una misión aérea de la NASA dedicada a estudiar cambios en la capa de hielo y el hielo marino en ambos polos del planeta. En la primavera de 2012, IceBridge llevó a cabo sucuarta misión ártica, sobrevolando...

On August 1, 2008 a rare total solar eclipse will appear in the skies over parts of Canada, Greenland, Russia, Mongolia, and China. During this spectacular event, the moon will cross in front of the sun, completely blocking out the sun's...

How can Greenland's ice sheets still be more than 10,000 feet thick, if carbon dioxide is warming the planet?<b<b<br/>r/>r/>

Operation IceBridge just completed 40 research flights over ten weeks, including three based out of the remote and beautiful islands of Svalbard, Norway. Here is the story of one of its most distinctive missions, called...

The United States has the world’s largest military budget by some distance, so it’s no surprise they have a massive global presence. In this video we take a look at some of America’s lesser known overseas bases and some of their...

A glimpse into the lives of three Greenlanders: a hunter, a ship’s captain and a fisherman, individuals whose very existence and heritage is intertwined with the Arctic Ocean. Like many who live in the polar north, their fortunes...

Iceland and Greenland Both are countries .um, well, Greenland is not exactly its own country. It's part of the Kingdom of Denmark, considered a self-governing constituent country. So it's almost a country? Kind of a country? Well, most...

Operation IceBridge has wrapped up its 2015 Arctic field campaign after covering a vast expanse of science targets during 33 different flights over land ice, sea ice, and glaciers. For more on the mission and the science it produces,...

Nearly every spring since 1991, researchers including William Krabill of NASA's Wallops Flight Facility in Wallops Island, Va., have flown on a NASA aircraft over Greenland, collecting measurements of ice thickness from an altitude of...

Here's a small dose of how it feels to be part of NASA’s Operation IceBridge team during a typical Kangerlussuaq morning, from that frigid ride to the airfield to wheels up over gorgeous Greenlandic scenery. IceBridge is deep into its...

Take a break from your day to soak in the sights and sounds of an Operation IceBridge flight over Greenland's southwest coast. This video features both the rugged scenery of Greenland and the somewhat rugged interior of a NASA C-130, the...

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...

Since measurements of Jakobshavn Isbrae were first taken in 1850, the glacier has gradually receded, finally coming to rest at a certain point for the past 5 decades. However, from 1997 to 2006, the glacier has begun to recede again,...

From the South Pole to Greenland, from Alaska’s glaciers to Svalbard, NASA’s Operation IceBridge covered the icy regions of our planet in 2017 with a record seven separate field campaigns. The mission of IceBridge, NASA’s...

If this weather-controlling air current moves northward, the U.S. and Europe are in for centuries of nasty weather.<br/>

We tend to think of Earth's landmasses as being fixed in place, but in reality they are attached to moving tectonic plates that constantly jostle for position. In some areas these tectonic plates slide over a hotspot - an...
