  1. Salinity anomalies in the Subpolar Gyre and the Nordic Seas Norwegian Meteorological Institutemet.no

  2. Part 1: Results from Curry & Mauritzen (2005) Objectives: • quantify how much additional fresh water it took tocause observed changes in salinity • how fast this fresh water entered the sub-Arctic ocean • where this fresh water was stored • assess the impact of freshening on the Atlantic MOC

  3. 1.8m fresh-water 3.0m fresh-water Objective 1how muchadditionalfresh waterdid it take?

  4. Great Salinity Anomaly figure fromwhoi.edu/oceanus Objective 2how fast did the additional fresh water entered the sub-Arctic?

  5. Objective 3where was the additional fresh water stored?

  6. Objective 4how does freshening affect the Atlantic MOC? Faroe Bank Channel Denmark Strait

  7. Part 2: Recent changes
