Polarstern and the MOSAiC Expedition

The Bremerhaven postmark on this pre-stamped International Polar Year envelope from Germany commemorates the MOSAiC Expedition. This was a one year expedition that turned the RV Polarstern into a drifting Arctic observatory to study effects of climate change. It involved several countries and hundreds of researchers, making it the largest Arctic expedition in history.
