Seasonal inflow of warm water onto the southern Weddell Sea continental shelf, Antarctica
To capture the austral summer to winter transition in water mass properties over the southern Weddell Sea continental shelf and slope region Weddell seals were tagged with miniaturized conductivity–temperature–depth sensors in February 2011. During the following 8 months the instruments yielded abou...
