Sea Ice Sensitivities in the 0.72 degrees and 0.08 degrees Arctic Cap Coupled HYCOM/CICE Models
Perennial Arctic ice extent, which corresponds to the sea ice that remains during the summer minimum, has decreased over the years 1979 2007 by more than 10% per decade (Comiso et al., 2008). The decline has been faster over recent years, leading to very low ice concentration in the summers of 2007...
