During World War II the German Navy, trying to compensate for the loss of meteorological data from stations in Greenland, Iceland and other areas of the northwestern Atlantic Ocean, established automatic weather stations, weather ships and manned weather stations in a zone stretching from Labrador to Zemlya Frantsa-Iosifa. In summer 1944 one of the last of the manned stations (code-named Haudegen) was established on Svalbard at Wordiebukta, Rijpfjorden, Nordaustlandet. A party of 11, led by geographer Dr Wilhelm Dege, collected and transmitted weather data from 14 September 1944 to 5 September 1945; the party also explored and mapped the ice-free corridor extending south across Nordaustlandet to the head of Wahlenbergfjorden and much of the north coast from Kapp Loven east to Finn Malmgrenfjorden. After the German surrender in May 1945 the men of Haudegen found themselves apparently forgotten by Allied authorities in Norway, and began preparing for a second winter. They surrendered ultimately to the captain of the Norwegian sealer Blaasel on 4 September 1945, and were thus the last members of the German armed forces to surrender at the end of World War II.
