Environment
The mooring S1, operational since June 2014, is located in the eastern Fram Strait, south-West offshore Svalbard region. Here, water masses, strongly influenced by the interaction between Atlantic and Arctic waters and by local atmospheric forcing, substantially contribute to driving the global thermohaline circulation.

In this region, there is remarkable variability in the system due to several forcing mechanisms (e.g., atmospheric, internal, tidal, shelf dynamics) that play an important role, especially in the upper layer. On the contrary, it is not completely clear which processes are responsible for the inter-annual and seasonal deep flow variability in the western offshore Spitsbergen region.

The mooring S1 is specifically designed to collect ocean parameters (temperature, salinity, dissolved oxygen, turbidity, sediment flux, ocean currents) in the deep layer, covering approximately the last 150-250 m of the water column.

The mooring was deployed for the first time in June 2014 in the framework of the Eurofleets project PREPARED. It is maintained by OGS and CNR-ISP (Italy), and since 2017 with the collaboration of the Italian Navy Hydrographic Institute
