Although today the Arctic is a hotspot of climate change, data sampling is still sparse due to the large sea ice cover. Yet both the historical and the modern observational data are important for long-term climate [...] database contains almost 290.000 quality checked oceanographic profiles for the Arctic Mediterranean north of 65°N in the time period 1980-2015. It thus represents a unique tool to study long-term changes
