Thermohaline intrusions in the Arctic Ocean: Cross-front intrusion slopes and driving mechanisms

Tracking intrusions from profile to profile, we show that the intrusions slope upward toward the cold fresh side of the front, relative to horizontal surfaces. This cross-front slope is in the sense expected for driving by buoyancy fluxes from the salt-finger form of double diffusion. It is the wrong sense for driving by the diffusive-convection form. Relative to isopycnal surfaces, the cross-front intrusion slope is opposite: downward toward the cold fresh side of the front. Thus, the intrusion slope lies between the slopes of horizontal and isopycnal surfaces, in the ``wedge'' of baroclinic instability. This indicates that baroclinicity is an additional driving mechanism for interleaving.
In summary, the cross-front slopes suggest that the intrusions are driven by salt fingering and baroclinicity; opposed by diffusive convection. Assuming a simple steady-state balance, we estimate that 30% of the driving comes from salt fingering, while the remaining 70% arises from baroclinicity.

Recent findings of boundary layer dynamics and sediment transport processes on the Scotian Shelf
Michael Li
Geological Survey of Canada
Bedford Institute of Oceanography
4:30pm, Thursday, May 14, 1998
Water movement coupled with salinity transportation is calculated on a grid that is curvilinear in the horizontal direction and which sigma-coordinates in vertical.
The suspended sediment transport model is driven by a database which is generated by the hydrodynamic model. The flocculation process and availability of sediment onbed for erosion are included.
The model structure will be introduced and the first modelling result will be discussed.
