Cruise reports for the Petermann 2015 expedition

Why is Petermann Glacier melting, and should we be worried?

We wonder why Greenland glaciers are currently melting and where their fresh meltwaters go. All this extra freshwater is causing sea-level rise and could disturb the whole ocean circulation of the North Atlantic.

New ways of long-term underwater sensing

The LoTUS, Long Term Underwater Sensing, bottom lander system is a new and innovative temperature probe, designed for operations in remote regions for up to 10 years in water depths up to 2,000 m, including a secondary drift function, that transmits the buoys GPS coordinates at pre-set intervals.

Trace carbon dioxide and methane along the coast of Greenland

By making continuous measurements of carbon dioxide and methane above the Arctic sea surface, we will improve our understanding of the fluxes of these gases between the atmosphere and ocean.

History of the Petermann Glacier

The Petermann 2015 expedition targeted the Petermann Glacier, Petermann Fjord, and the adjacent Hall Basin of Nares Strait.
