They suggested that the trench water is rather freely exchanged by isopycnal mixing with the bottom water overlying the Northwest Pacific abyssal plain.
The site for this Global Array at the edge of the Southern Ocean, chosen based partly on findings by the Diapycnal and Isopycnal Mixing Experiment in the Southern Ocean (DIMES), is another key part of the Earth's "global ocean conveyor" circulation.
The derived estimates are applied to evaluate the deviations of isopycnal surfaces from their undisturbed positions under the impact of internal waves (equivalently, the amplitudes of internal waves) and velocity fields in such waves in prospective locations of oil and gas platforms on the shelf of Sakhalin.
Because the ocean is made up of many layers of water that are dependent on temperature and salinity, water moves easily along horizontal or isopycnal layers, but mixes only slowly across the layers, known as diapycnal mixing.
The hybrid coordinate in HYCOM is isopycnal in the open, stratified ocean, but smoothly reverts to a terrainfollowing coordinate in shallow coastal regions, NCODA uses the model forecast as a first guess in a multivariate Optimal Interpolation scheme and assimilates available satellite altimeter observations satellite and in situ SST as well as available in situ vertical temperature and salinity profiles from XBTs, ARGO floats and moored buoys.
