An estimation of the effect of a possible wind speed increase on the ocean mixed layer depth at the northern Patagonian continental shelf
A possible deepening of the ocean mixed layer is investigated at two selected points of the Patagonian continental shelf where a significant positive wind speed trend is estimated. Using a 1-dimensional vertical numerical model on a long term simulation (1979-2011) it is found that the mixed layer t...
