Modeling the impact of declining sea ice on the Arctic marine planktonic ecosystem
International audience We have developed a coupled 3-D pan-Arctic biology/sea ice/ocean model to investigate the impact of declining Arctic sea ice on the marine planktonic ecosystem over 1988-2007. The biophysical model results agree with satellite observations of a generally downward trend in summ...
