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

Baltic Sea Travels 2013 and 1945

A massive ice sheet covered much of northern Europe just as Greenland is covered today. As climate warmed about 12,000 years ago, the ice sheet retreated leaving a large puddle of water behind that we now call the Baltic Sea. It is a shallow estuary, only about 55 meters deep on average, that separates Finland from Sweden in the north while Russia, Estonia, Latvia, Lithuania, Poland, and Germany form its southern reaches with Denmark and Sweden filling in the western borders of this sea in the north. The history of all these 9 countries is shaped by the trade, travel, and turmoil that the tide-less Baltic Sea provided for well over 1500 years.

Europe during the last ice age about 50,000 years before present when a massive ice sheet covered much of Scandinavia, Britain, and the Baltic. Note that North Germany and Denmark are ice-free in the west, but ice-covered in the east. [From WikiPedia]

Europe about 50,000 years before present with a massive ice sheet that covered much of Scandinavia, Britain, and the Baltic. Note that North Germany and Denmark are ice-free in the west, but ice covered in the east. The coast of Norway is ice-free also. [From Wikipedia]

Traveling by car, train, and ferry the last 10 days, I visited colleagues, family, and friends in an area shaped by ancient ice sheets, medieval trade, piracy, and modern conflict. Continue reading

Travels by Mind to the Glaciers and Oceans off North-East Greenland

Our minds travel easier than the body. My eyes have never seen East Greenland, but I moved across its white Continue reading
