In this region, ocean currents from lower latitudes impact the sea water temperature, and the ocean is a heat storage affecting the local climate. Although Ny-Ålesund is situated in the high Arctic (78.9°N, 11.9°E), daily mean temperature in summer is above the freezing point. The interannual temperature variability in winter
