By analyzing satellite photos, geologists are able to measure the depth of the lakes that form on glaciers during the summer months. Fascinatingly, the process that produces these lakes is also responsible for their remarkable depth.
As a support scientist for NASA’s Operation IceBridge mission, Jeremy Harbeck spends most of his time processing data at NASA’s Goddard Space Flight Center in Maryland. But it was on a recent visit to Greenland that he snapped this striking composite image of an iceberg frozen into North Star Bay.
NASA scientists have used ice-penetrating radar to create a remarkable visualization of the many frozen layers that constitute Greenland's expansive ice sheet.
After staring at a barren seafloor for nearly three hours, National Geographic's Alan Turchik couldn't believe his eyes when a rare deep-sea Greenland shark suddenly drifted across the screen. (Warning: an excessively long stream of bleeped-out expletives to follow)
During a secret Cold War spying mission in 1947, a B-29 Superfortress made an emergency landing in northwest Greenland. It lay there undisturbed until 1994 when a botched mission to repair and return it failed. NASA recently caught a glimpse of its charred remains.
Scientists working in Greenland have discovered an extensive aquifer of meltwater that sits under the Greenland ice sheet all year round — but it's not known if this reservoir, which is about the size of Ireland, will ever make its way to the ocean.
If the ice sheets on Greenland ever melt, this is what you'll see. It's an enormous canyon cutting through the center of the island, the size of the Grand Canyon. Scientists recently discovered it with ice-penetrating radar.
April is Earth month. To drum up public interest in both understanding and sustaining the planet, NASA has launched a great interactive image gallery that explores "Earth Science Highlights" in the form of stunning photographs and visualizations.
For nearly 500 years, the Vikings lived and thrived in Greenland. Taking advantage of the Medieval Warm Period, they established outposts in the North Atlantic where they farmed and ranched. But quite suddenly, at the mid-point of the 15th century, they abandoned their settlements and ventured back to Scandinavia.…
Ho-lee-crap. You're looking at the largest iceberg calving ever recorded — a whopping 7.4 cubic km (that's 1.77 mi3) hunk of ice, detaching itself from Greenland's Ilulissat glacier — captured by filmmaker James Balog. It's just one of the scenes in Balog's forthcoming film Chasing Ice, and it is remarkable to behold.
It was just yesterday when we showed you what would happen if you got too close to a melting glacier in Greenland — a disturbing glimpse of what's becoming a regular fixture in that part of the world. And now, as we find ourselves having to endure yet another scorchingly hot July, new data from NASA indicates that…
The asteroid that hit Earth 65 million years ago and wiped out the dinosaur was at least six miles across and left behind a crater over 110 miles across. But that's nothing compared to a possibly newly discovered impact site.
Exactly one hundred years ago today, an ocean liner struck a block of ice and sank in the North Atlantic. The story of the ocean liner has been told hundreds of times. This story is about the block of ice.
Now known as one of the most inhospitable places on Earth, the giant arctic island of Greenland might actually hold the birthplace of all life on Earth. Yes, all life on Earth might well have sprang from Greenlandic mud volcanoes.
In 1492, Christopher Columbus landed in what is now the Bahamas, changing the world forever. But was he first non-indigenous person to reach the Americas? Vikings got there before him, and possibly Polynesians too...and those are just the sane theories.
What do Viking colonies teach us about space colonization? The former offers a dire lesson about why the latter may become necessary. Paul Gilster of Centauri Dreams discusses the circumstances that could force humanity to avoid a "planetary Greenland."
Although climate change could still have devastating effects for much of the world, some regions stand to benefit immensely. Canada, Scandinavia, and even Greenland could all become economic powerhouses, making "The New North" a very attractive destination.
After five years of drilling through 1.6 miles of solid ice, scientists finally hit Greenland's bedrock last week. The buried rock holds secrets to how Earth's climate changed 100,000 years ago, and what it means for today's climate upheaval.
For the past several years, scientists have been tracking the transformation of the Greenland Ice Sheet. Now it's shrinking faster than ever, and a new study proves it has lost 1500 gigatons of mass from 2000 to 2008.
