Ocean Sciences

Matthis Auger

I am a physical oceanographer and currently a postdoctoral researcher at the University of Brest. My research focuses on circulation in the Southern Ocean, with particular interest in ice-covered regions. I combine a wide range of observations (satellite altimetry, in situ measurements) with numerical simulations to investigate heat transport, dense water circulation, and ocean variability along the Antarctic margins.

How atmospheric circulation patterns high above the Southern Ocean influence the deepest layers of the global ocean

The ocean surrounding Antarctica plays a crucial role in the climate system. Along parts of the Antarctic coast, very cold and salty water becomes dense enough to sink all the way to the ocean floor. This process forms Antarctic Bottom Water: the deepest water mass in the global ocean, representing about 40% of its total …[Read More]
