Description

<p>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 gives the first mapping of sea ice production in the both polar oceans, based on heat-flux calculation with ice thickness data derived from satellite data. The Cape Darnley polynya in East Antarctica is found to be the second highest production area, suggesting a possible AABW formation area. This mapping will provide new information with which to validate coupled ice-ocean models while providing important boundary conditions for the various models.</p>
