Land-Fast Ice Cover off North Greenland: Will NASA bite?
by Andreas Muenchow in Icy Seas
When a large outlet glacier of North Greenland (Petermann Gletscher) discharged an ice island four times the size of Manhattan in August of 2010, the United States’ Congress held formal inquiries on its cause within days of the event. Congressmen, … Continue reading →... Read more »

The Turbulence of Van Gogh and the Labrador Shelf Current
by Andreas Muenchow in Icy Seas
Vincent Van Gogh painted his most turbulent images when insane. The Labrador Current resembles Van Gogh’s paintings when it becomes unstable. There is no reason that mental and geophysical instability relate to each other. And yet they do. Russian physicist … Continue reading →... Read more »

Petermann Photos, Places, and People
by Andreas Muenchow in Icy Seas
Petermann Gletscher sent off Manhattan-sized islands of ice in 2010 and 2012 that now litter the eastern seaboard of Canada from its farthest northern Ellesmere Island to its farthest eastern Newfoundland. The ice is streaming south along thousands of miles … Continue reading →... Read more »

Cockpit’s View of Greenland’s Glaciers, Ice-Sheets, and Sea-Ice
by Andreas Muenchow in Icy Seas
The glaciers and ice-sheets of Greenland retreat and melt in a warming world. Towering almost 3000 meters above sea level the ice-sheet is so thick and heavy that it depresses the bedrock underneath below current sea-level. Monitoring the ice-sheet, outlet … Continue reading →... Read more »

Oceanography, Technology, and Ships
by Andreas Muenchow in Icy Seas
Sea-going oceanography is in transition. Times are exciting as we developed new tools, sensors, and ideas on how to observe the ocean and the stuff that lives in it, floats on it, and is submerged below it. I just learned … Continue reading →... Read more »

Academic Freedom and International Collaborations
by Andreas Muenchow in Icy Seas
Working in the Arctic is hard. Despite climate warming, despite diminishing ice cover, despite public interest and global impact, it is still a hostile and challenging place. It is also very expensive to get to. It usually takes me 2-4 … Continue reading →... Read more »

Petermann Glacier Ice Islands: Where are they now?
by Andreas Muenchow in Icy Seas
Two large calving events in 2010 and 2012 reduced the floating part of Petermann Gletscher by 44 km (28 miles) in length, 6 Manhattans (380 km^2) in area, and 42 giga tons in mass. But what’s a giga ton? ... Read more »

Shots of Airborne Lasers at Petermann Gletscher, Greenland
by Andreas Muenchow in Icy Seas
If shots of whiskey make you dizzy, shots of laser stun. NASA stunned me this week, when I discovered that they provide millions such shots of Greenland from which to construct detailed images of the landscape. The shots are free, no age-limit. This is better than the usual remote sensing or photography of “just” brightness. The laser gives us height, and not just the perception of it by shadows and fake angles of illumination, but hard and direct measurements of, well, height above sea leve........ Read more »
