Antarctic sea ice is constantly exported from the shore by strong near surface winds that
open leads and large polynyas in the pack ice. The latter, known as wind-driven polynyas,
are responsible for significant water mass modification due to the high salt flux into the
ocean associated with enhanced ice growth. In this article, we focus on the wind-driven
Terra Nova Bay (TNB) polynya, in the western Ross Sea. Brine rejected during sea ice
formation processes that occur in the TNB polynya densifies the water column leading to the …
