Intra-annual variability of the mixed layer parameters in the Okhotsk Sea
All available oceanographic data for the deep-water part of the Okhotsk Sea, in total 111,944 stations collected in 1931–2014, are analyzed after removing the duplicate and lowquality ones. The mixed layer depth is determined on the water temperature profle for each station and monthly mean values o...
