| Outline of Final Research Achievements |
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 sea ice production dataset for the Southern Ocean, based on heat flux calculations and satellite-derived sea ice data. 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.
