Petermann Ice Island Breaks while Plowing into the Bottom

The Manhattan-sized ice island that last year broke free of Petermann Gletscher in North Greenland plowed into the bottom and broke apart. Force equals mass times acceleration. When 18 giga tons (mass) of moving ice crashes into the ocean’s bottom 200 meters below the surface (acceleration), then something gotta give. And give it did, Continue reading

Petermann Ice Island visited by Vagabond

An ice-cube with a mass of 18 giga tons left Petermann Gletscher in the summer of 2012 and thus became PII-2012 for Petermann Ice Island 2012. The CCGS Henry Larsen visited and surveyed the waters, bottom, and ice of the fjord that same year. Since then PII-2012 traveled 300 km southward, grounded in shallow water, but continued its voyage south a month or so again. Last thursday it was visited by a 47′ sail boat called “Vagabond.” I just discovered the report by its Master Eric Brossier, Continue reading

Canyon below Ice at Petermann Gletscher

The Grand Canyon of Arizona stands tall in the mind as the Colorado River carved itself into 6000 feet of rock. A similar canyon has been discovered in northern Greenland near Petermann Gletscher. The canyon without a name is buried under 6000 feet of ice, but its size and scale Continue reading

Thule on My Mind: Deep Water Port and Air Force Base

I am an air force brat. My father and my father-in-law enlisted in the German and US Air Forces, respectively. They served during the Cold War when I was born in 1961 a few month after the Berlin Wall went up. My father-in-law was stationed in Thule, Greenland, a northern forward base with radars to detect ballistic missiles, fighter jets to intercept planes, and bombers to retaliate in nuclear war. About 60 years later, the fighter jets, bombers, and communist threat are all gone, but the base is still there, and to me it is the gateway to North Greenland. Both US and Canadian Coast Guard icebreakers call its port to receive or discharge crews and scientists such as myself in 2003, 2006, 2007, 2009, and 2012.
