The Competition of Tidal Mixing and Freshwater Forcing in Shaping the Outflow from Hudson Strait

Abstract

A fresh plume, driven by the large riverine input into Hudson Bay, flows along the southern shore of Hudson Strait as a buoyant coastal current (Straneo and Saucier, 2008a and b). In the strait, the plume is subject to one of the largest semi-diurnal tides in the world and therefore to intense tidal mixing. The long-term goals of this project are to understand how these two competing stratification-inducing (the freshwater) and the stratification-destroying (the tidal mixing) interact, in Hudson Strait, to result in the observed coastal current and its variability. Next, we plan to generalize our results in the form of dynamical balances applicable to other coastal regions, estuaries and straits.
