Like Weather Station Mike, hydrographical measurements in the western Fram Strait are listed among the top five very important, yet not secured, time series in the 2003 NRC report. NPI has maintained an array of moorings here since 1990, measuring the freshwater (liquid and solid) and volume fluxes out of Fram Strait. Under DAMOCLES parts of this infrastructure are secured.

Under iAOOS Norway we will build on this infrastructure but fill the gaps that insufficient funding under DAMCLES left open. Similar gaps are filled for the DAMOCLES array at 74° N, allowing us to estimate the freshwater transport divergence between the arrays and hence the leakage of freshwater from the EGC/Transpolar Drift into the Greenland and Iceland Seas by feeding the data into DAMOCLES and tasks 3.8 and 3.9 of this proposal. Filling the gaps involves adding a tube mooring and an ADCP on the shelf at 79 N, adding TS sensors in the upper layers of the 79 N array and by adding a ULS at 74° N.
