Scientists used cutting-edge technologies to uncover six amazing secrets hidden under the Greenland ice sheet.<br/>

How much and how fast will sea level rise in the coming decades? What makes sea level rise hard to predict? Who will be affected?



NASA experts and guests discuss how sea level has risen an average of about seven...

NASA Kicks Off Antarctic Mission



This is the first year that IceBridge will operate directly from Antarctica, flying from McMurdo Station starting in mid-November instead of from southern Chile. This change will allow...

Join Operation IceBridge Project Manager Christy Hansen on location near Antarctica as she discusses her career at NASA. Hansen, who began in NASA's space flight program, recently joined the Operation IceBridge team. As Project...

New NASA research found that large crevasses provide aquifer water upstream of Greenland's Helheim Glacier with a clear escape to the ocean. This discovery helps confirm that the water, which is held in a layer of...

Scientists at the University of Alaska Fairbanks’ Geophysical Institute used data from NASA’s Operation IceBridge to develop a more accurate model of how the Greenland Ice Sheet might respond to climate change in the...

NASA Glaciologists Kelly Brunt and Alex Gardner discuss the history, challenges, and evolution of mapping the Antarctic continent and what it means for science and society.

In a remote area of northwest Greenland, an international team of scientists has made a stunning discovery, buried beneath a kilometer of ice. It’s a meteor impact crater, 300 meters deep and bigger than Paris or the...

NASA scientists and ice sheet modelers, Ryan Walker and Christine Dow, traveled to a remote location on the coast of Antarctic to investigate how tides affect the movement and stability of the Nansen Ice Shelf, a 695-mile...

Since the late 1970's, NASA has been monitoring changes in the Greenland Ice Sheet. Recent analysis of data from both the ICESat satellite and an ongoing airborne mission called Operation IceBridge show us how the surface elevation...

In this week’s episode of NSF Science Now, we examine an engineering breakthrough in Type 1 diabetes that could help dogs and humans alike; targeted reading programs that re-wire the brains reading circuitry, and finally, we explore...

Follow an entire orbit of the ICESat-2 mission as it measures the elevation of oceans, sea ice, mountains, and islands around the Earth. This video shows the same orbit (ground reference track 1352) on...

Earth's polar regions: the "canary in the coal mine" of global climate change. The time to learn more is now. Two years of intensive research and education focused on the Earth's poles began March 1, 2007 with the launch of the...

For the first time in its seven years of flights, NASA's Operation IceBridge, an airborne survey of changes in Earth’s polar ice, is conducting overlapping campaigns in Antarctica and the Arctic.

A new study using satellite images finds that Greenland’s glacier melt is accelerating.

Enjoy a deep dive into sea level rise research as NASA scientists and their colleagues discuss their research on and around the Greenland Ice Sheet.

Five years after a NASA-funded field study returned to to set up camp once again in the melt zone of the Greenland Ice Sheet, a new study adds to the rich findings from this innovative project. We look back on...

Peering into the thousands of frozen layers inside Greenland’s ice sheet is like looking back in time. Each layer provides a record of not only snowfall and melting events, but what the Earth’s climate was like at the dawn of...

Greenland’s ice sheet contains enough ice to raise global sea levels by 6 meters, and it’s melting at an alarming rate.

At the Stable Isotope Lab in Boulder, Colo., scientists are doing a lot of the same things that those CSI folks do on TV. But instead of being "crime scene investigators," these experts are more like "cold scene investigators."...

For 11 years from 2009 to 2019, the planes of NASA’s Operation IceBridge flew above the Arctic, Antarctic and Alaska, gathering data on the height, depth, thickness, flow and change of sea ice, glaciers and ice...

Learn how NASA uses lasers to keep tabs on Antarctic glaciers and sea ice with a series of manned airplane flights over the most remote continent on Earth.



U.S. Ambassador to Chile Michael Hammer and NASA Chief...

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...

For the first time NASA’s Operation IceBridge is flying simultaneous missions over both the Arctic and Antarctic, on smaller, faster aircraft. These campaigns and aircraft represent both a unique opportunity for measuring polar ice, and...
