Modelling of deep water renewal through cold convection plumes / Finn Thorkildsen, Peter M. Haugan.

Title: Modelling of deep water renewal through cold convection plumes / Finn Thorkildsen, Peter M. Haugan.
Author(s): Thorkildsen, Finn.
Haugan, Peter M.
Date: 1996.
Publisher: Cambridge: Sea Ice Group, Scott Polar Research Institute, University of Cambridge
In: ESOP. European Subpolar Ocean Programme. Sea ice - ocean interactions. Volume 2. (1996.),
Abstract: Small areas of vertical flow, so-called plumes, were modelled to understand transport mechanisms. Plumes with mean vertical downward transport are modelled by a steady-state model. An entrainment hypothesis, based on knowledge about in-mixing of water across the shear zone from an area of low turbulence into an area of high turbulence is used. This results in a model using conservation equations for momentum, heat and salt, and a non-linear equation of state of sea water. The depth reached by surface water when moving through stationary plumes is predicted. In weakly stratified cold water, such as the Greenland Sea, deep convection is found to be possible and efficient through small steady-state plumes. Initial excess density, caused by low temperature, gives deep convection (deeper than 1500 m) due to the thermobaric effect. (The model is described on pp. 456-462).
