WebOct 8, 2010 · 1. Introduction [2] The Arctic Ocean's surface mixed layer (ML) constitutes the dynamical and thermodynamical link between the sea ice and the underlying waters. Wind stress, acting directly on the ML or via wind-forced ice motion, produces ML currents that in turn drive deep ocean flows. WebThe oceanic mixed layer is located above the thermocline, which separates the warm surface water from the cold deep ocean water. Its thickness, which varies from a few metres to a few hundred metres, depends on the …
