Environmental Influences on the Production of Arctic Halocline and Deep Water
Pease (1987) related the effects of atmospheric forcing, mainly temperature and wind fields, to the size of coastal polynas. Using Pease's formulation and Killworth's (1977) plume model as applied by Melling and Lewis (1982), the effects of atmospheric forcing on brine injection into the A...
