Ocean-Ice-Atmosphere Interactions in the Terra Nova Bay Polynya, Antarctica
Abstract: Antarctic coastal polynas are, at the same time, sea-ice free sites and 'sea-ice factories'. They are open water surface locations where water mass transformation and densification occurs, and where atmospheric exchanges with the deep ocean circulation are established. Various mo...
