2. D2.8 DoW
Better and less resource demanding estimates of volume- and heat transport in the Atlantic inflow to the Nordic Seas will be obtained by better integration of satellite data with the existing GSR observatory. This will also allow more rapid data availability and access for a wider modeling community. Improvements in estimates will be achieved by developing algorithms integrating new Earth Observations when operational (Jason/Sentinel)

3. TMAs on the Greenland-Scotland Ridge

4. Shetland Branch
Norröna track
Satellite tracks
Current transport line

5. Shetland Branch
Work initiated to establish an improved estimate for the geoid in the region
Analysis is ongoing to shift from gridded SLA to along track product
Combined, these results are expected to improve the transport estimates
Currently, two ADCPs are deployed on NOL-line, which is close to Norröna ship-based ADCP track and satellite track

GSR PIs have agreed to establish data DOIs for e.g. CTD standard sections, ADCP data and transport products
Meta data and relevant information will be shown similar to e.g.:
