1. Fresh Water Budget of the Arctic and Atmospheric Mode of Variability NSF -- Fresh Water Initiative Bruno Tremblay Robert Newton Lamont Doherty Earth Observatory

2. Objectives To quantify the contribution of the surface ocean currents to the fresh water flux from the Arctic to the Nordic seas To better understand the link between this fresh water flux and atmospheric forcing

3. Proposed Work Run a 3-D sea-ice ocean model using “observed” atmospheric forcing from reanalysis data synthetic forcing with realistic yearly variability

4. Ice Export vs NAO Tremblay, 2003

6. Fresh Water Budget of the Arctic Results by Meredith et al. 2001 suggest that the upper ocean contribution may be much higher Twice as large as the sea ice contribution Aagaard and Carmack, 1989
