Observing systems and technologies Cross-section across Fram Strait with temperature from CTD sections in summer along 78°50'N. The different moorings and instruments of AWI's FRAM mooring array [...] contributed to this effort by developing and maintaining the FRAM and MIDO infrastructure. We also use a large number of moorings which are anchored to the sea floor and allow for measurements between

surveys. Our focus areas are the boundary current from the Fram Strait to the Siberian Arctic and the upper Arctic basin. There is a strong link between the variability of physical parameters in [...] Atlantic water in the Eurasian Basin and the contribution of the Fram Strait inflow branch to the Arctic Ocean heat budget ,Progress in Oceanography, 132 , pp. 128-152 .doi:10.1016/j.pocean.2014.04.003 [...] Arctic Ocean through the Barents Sea or Fram Strait.

spring expeditions, autonomous ice-tethered buoy systems like FRAM or MIDO have enabled a nearly year-round, Arctic basin-wide coverage of temperature and salinity profile observations since 2006.

It enters the Arctic Ocean through the Barents Sea or Fram Strait. In the eastern Fram Strait, Atlantic Water flows northward in the West Spitsbergen Current between the surface and about 800m [...] . The AWI long-term observations in Fram Strait have been measuring the temperature, salinity, and velocity in the West Spitsbergen Current since 1997 (Figure 1). In the
