| A statistical evaluation of vertical current velocity profiles w(z) has been undertaken using data provided by current meter profilers. The calculation of profiles w(z) involves the estimation of the standard deviation of vertical current at each depth level, and the standard deviation of the statistical variability of that estimate. Profiles w(z) have been computed for the northwestern Black Sea, using current meter and CTD data from three surveys carried out during 1992-1994. The calculations show w(z) to have a two-layered structure, with zero values occurring in the main pycnocline. Such vertical current structures are consistent with a hydrodynamic model, whereby the current field is induced by buoyancy fluxes through the lateral basin boundaries.... |
