This conundrum regarding ocean mixing and upwelling in the deep ocean will be resolved by appealing to the fact that the ocean does not have vertical side walls. Implications of the conundrum for the representation of ocean mixing in climate models will be discussed.Ferrari, Raffaele...
This value is significantly greater than the traditional (1 cm2 s1) estimate based on water mass analysis5,6 of vertical eddy diffusivity in the deep ocean.doi:10.1038/251043a0THOMASH.BELLNature Publishing Group UKNatureBell, T.H., 1974. Vertical mixing in the deep ocean. Nature 251, 43-...
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....
Ocean Mixing Book2022, Ocean Mixing Leif N. Thomas, Xiaoming Zhai Explore book 5.6.1 Vertical mixing Vertical mixing driven by near-inertial motions and waves can be split into two categories: entrainment at the base of the mixed layer and mixing in the stratified interior. Entrainment caused ...
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 ...
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,...
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...
In shallow lakes with few rooted macrophytes (vascular plants), the mixed layer depth can easily reach the lake bottom, often resulting in increased sediment resuspension, water turbidity, and nutrient availability for phytoplankton. Surface mixing dynamics affect the transport of both dissolved ...
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...
In the Channel where light is not a limiting factor, increased mixing during spring tides enables nutrient replenishment from the water-sediment interface and phytoplankton responds immediately after nutrients have been renewed in the water column. In the more turbid waters of the Bay of Brest, ...
