Application of Interleaving Models for the Description of Intrusive Layering at the Fronts of Deep Polar Water in the Eurasian Basin (Arctic)
10 pages, 2 figures, 6 tables Interleaving models of pure thermohaline and baroclinic frontal zones are applied to describe intrusions at the fronts found in the upper part of the Deep Polar Water (DPW) when the stratification was absolutely stable. It is assumed that differential mixing is the main...
