Evaluation of transport relative to the tidal mixing front on southern Georges Bank
… and diffusive transport relative to the tidal mixing front in May 1999. Potential density measurements placed the tidal mixing front around the 50-55 m isobath on the southern flank. Drogued drifter movement relative to the front was on the order of the drifter's slip velocity and …

Variability of currents in Great South Channel and over Georges Bank : observation and modeling
… Channel and (II) numerical study of stratified tidal rectification over Georges Bank. In part I, the combined analysis of CTD, ADCP, satellite-track drifters, and zooplankton distributions in the northern Great South Channel clearly shows (1) the seasonal evolution of the surface low salinity …

Current velocity profiling from an autonomous underwater vehicle with the application of Kalman filtering
… estimate. Field data from the Haro Strait Tidal Front Experiment are processed by both methods. Current velocity estimation results reveal horizontal and vertical velocity structure of the tidal mixing process, and are also consistent with the vehicle's deviated trajectory. The capability …

Mechanisms and variability of salt transport in partially-stratified estuaries
… salinity gradient, and the amplitude of the tidal velocity is investigated with analytic and numerical models. The results indicate that salt transport increases dramatically during stratified periods when vertical mixing is weak. Analysis of salt transport from observations in the Hudson …

Numerical modelling of tidal flows around headlands and islands
This thesis presents a study of tidal flow interaction with headland and island features. Wake development in the lee of topographic features can generate complex two- and three-dimensional flow structures. The primary objectives of the research are to (i) determine the suitability of traditional …

A global map of tidal dissipation over abyssal hills
… such as the ocean. Such waves may be produced by tidal currents flowing over rough seafloors; they are then called internal tides. As they travel away from the seafloor, internal tides tend to attain high amplitudes and break into turbulent eddies. Their ability to carry and dissipate part of …

Observations and modelling of the variability of the Solent-Southampton Water estuarine system
… in the partially-mixed, non-turbid, macrotidal Solent-Southampton Water estuarine system (UK).<br/>The estuarine circulation and the response of wind forcing is examined using a three dimensional, free surface, finite volume and finite element grid model. Results from short-term (three …

Ice shelf-ocean interactions in a general circulation model : melt-rate modulation due to mean flow and tidal currents
… In a second time, the modulating effects of tidal currents on melting at the base of PIIS are examined. We find that the temporal variability of velocity-dependent melt rates under tidal forcing is greater than that of velocity-independent melt rates. Our experiments suggest that because …

Analysis of water masses distribution and circulation in the White Sea, Russia
… of fine-scale thennohaline structures. The mixing processes were thoroughly studied in the southwest area of the Gorlo Strait, where present water masses have an important contribution in the dynamics of the White Sea including water-exchange and deep-water renewal. Satellite images were …

The structure of the Kuroshio west of Kyushu
… front located near the shelf break. Horizontal mixing between the Kuroshio and coastal water was observed but was limited near the shelf break. In July, surface coastal water extended far past the shelf break over the Kuroshio region near the surface, and in turn, Kuroshio water intruded onto …

Physical constraints on phytoplankton in estuaries and shallow coastal waters
… of phytoplankton. The partially-mixed, macrotidal, temperate estuary Southampton Water is no exception, with reports of frequent temporal patterns of spring and summer maxima in algal biomass. During this study, the close coupling between the estuarine hydrology and the phytoplankton …
