The vertical mixing processes that bring nutrients back up into the photic zone and so restore fertility to the surface layer of the ocean, are described as upwelling and turbulence. The way in which upwelling arises from the meeting or deflection of deep currents, has already been described in...
Hydrophysical specificity is due to large horizontal gradients of all kinds, complicated vertical structure of hydrophysical properties, great importance of internal waves, turbulence, 3-D circulation and vertical mixing. Being interrelated, all these phenomena must be studied in complex....
Seasonal variations in vertical mixing intensity in the intermediate layer of the northern Okinawa Trough was deduced using the seasonal variations in salinity in the North Pacific Intermediate Water (NPIW) using two distinct datasets: the World Ocean Atlas 2013 and historical conductivity, temperature,...
are influenced by ocean dynamical processes, including oceanic planetary waves, boundary currents, eddies, and mixing. The area and depth of all types of MHWs exhibit significant increasing trends over the past two decades. These results contribute to a better understanding of the physical drivers ...
mixing efficiencies Gamma(alpha) (alpha stands for heat, salt and momentum). However, to compute the diffusivities, one needs additional information, specifically, the dissipation epsilon. Since a dynamic equation for the latter that includes the physical processes relevant to the ocean is still not...
governed by the forcing of the wind field and secondarily by deep water tides. In detail however, the budget of mechanical energy input into the ocean is poorly constrained. The now inescapable conclusion that over most of the ocean significant “vertical” mixing is confined to topograph...
It is an open question whether turbulent mixing across density surfaces is sufficiently large to play a dominant role in closing the deep branch of the ocean meridional overturning circulation. The diapycnal and isopycnal mixing experiment in the Southern Ocean found the turbulent diffusivity inferred ...
