WP 1: In situ observations:

• Task 1.1: Standard section Svinøy

  Objective: Develop the Svinøy Section into a complete, sustainable, simple and robust upstream reference-system for monitoring the Atlantic inflow toward the Arctic Ocean during IPY.

• Task 1.2: Measurements at Weather Station Mike

  Objective: Secure the continuation of Station M ocean time series, augment the observations with modern instrumentation, and make autonomous transects of the Norwegian Atlantic Current using gliders.

• Task 1.3: Radiation measurements at Bjørnøya and Weather Station Mike

  Objective: Update Bjørnøya and OWS Mike with modern instrumentation for radiative fluxes, to obtain a data set for the WP3 validation of EUMETSAT Ocean and Sea Ice Radiative Fluxes.

• Task 1.4: Heat -, salt - and mass flux measurements in the Fugløya-Bear Island section

  Objective: To secure the continuation of the monitoring of the Barents Sea branch of the Atlantic Water inflow to the Arctic during IPY.

• Task 1.5: The Norwegian Atlantic Current bifurcation at 73oN; glider surveys in the Gimsøy- and Bear Island West sections

  Objective: Implement a system of autonomous platforms to obtain detailed hydrographic data at the NwAC bifurcation at the western entrance to the Barents Sea.

• Task 1.6: Mooring section Fram Strait East – the West Spitsbergen Current

  Objective: Extend the Fram Strait East monitoring line with a mooring on the shelf break, that will enable us to capture the strongest signal in the topographically vorticity wave field.

• Task 1.7: Drifting Stations Tara and NP-35

  Objective: Contribute to the logistics necessary to carry out the Tara drift station, and install instrumentation at Tara and NP-35 necessary to feed data into the ice albedo feedback studies in WP3.

• Task 1.8: Drifting station KV Svalbard

  Objective: To carry out two intensive winter/spring field campaigns that provide new data from the output end of the Transpolar Drift that are required for the relevant tasks in our WP3 and other iAOOS upstream components.

• Task 1.9: Freshwater mooring sections along the East Greenland Current; 79 and 74°N

  Objective: To fill the gap in instrumentation in the freshwater observation arrays that prevents us from calculating the freshwater transport divergence between the individual arrays.

• Related Task: Mooring section Nordaustlandet

  Objective: To complete the DAMOCLES and NABOS mooring array north of Spitsbergen to be able to fully capture the inflow of Atlantic Water to the Arctic.
