Abstract
The sinking of dense water in the polar oceans plays a key
role in global thermohaline circulation, leading to heat and material
exchange between the atmosphere and deep ocean. This study
provides the first surface heat and salt flux dataset for the Southern
Ocean (including a treatment of sea ice growth and melt), based
on heat flux calculations and satellite-derived sea ice data. The
geographical distribution of annual net heat (salt) flux shows a
distinct contrast: significant cooling of (salt release into) the ocean
occurs in the coastal region, and net heating of (freshwater release
into) the ocean occurs in the offshore region. The work tries a
quantitative representation of heat and freshwater transport by sea
ice formed in the coastal region to offshore. Since hemisphericscale
heat and salt fluxes associated with sea ice growth and melt
have not been estimated from observations to date, the present
dataset will provide new information with which to validate
coupled ice-ocean models while providing important boundary
conditions for the various models.
