| Summary: | The geographical and environmental conditions of the Arctic region make it one of the most remote, harsh and challenging regions on Earth to observe. Indeed, being covered by sea ice all year round, the Arctic Ocean is the least observed and therefore the most unknown component of the whole Arctic climate system. In particular, the sea ice cover hampers both the access by ships and the observations via remote sensing, thereby hindering long-term monitoring. Yet, the Arctic Ocean and the neighbouring Nordic Seas, play a crucial role in the cycling of fresh water and heat across the global ocean. Changes in the Arctic Ocean circulation have been induced by global warming, that modified the atmosphere-ice-ocean interface. Up to recent times, changes in the circulation in the ice-covered Arctic have been observed mainly via in-situ data (e.g., ship observations and moorings), which are sparse and mostly cover short periods of time. Strong seasonal biases make it difficult to integrate in-situ observations to ... |
