Abstract: The stability of inviscid frontally trapped waves along a shelfbreak is examined to determine whether frontal instabilities may contribute to the alongfront variability frequently observed. Three different basic states ...

Abstract: A depth-averaged model with no density variations was used by Chapman to describe the formation of a passive tracer front at a shelfbreak. The relevance of this frontogenesis mechanism to cases that allow vertical variations ...

Abstract: Each year the hydrography of the Middle Atlantic Bight changes dramatically from winter conditions with strong horizontal gradients of temperature, salinity, and density at the shelf break separating shelf and slope waters ...

Abstract: The recent theoretical approach of Visbeck, Marshall, and Jones is used to examine shallow convection and offshore transport of dense water from an idealized coastal polynya. A constant negative buoyancy flux is applied ...

Abstract: Surface drifters at 10 and 40 m are analyzed to assess cross-frontal exchange characteristics within the Middle Atlantic Bight. This Lagrangian analysis shows a shelfbreak jet characterized by strong and ubiquitous meandering. ...

Abstract: A mechanism is described for the formation or a front at the edge of a continental shelf in an initially linearly stratified fluid lacking horizontal density gradients. A primitive equation numerical model is used with a ...

Abstract: hrough combining analytical arguments and numerical models, this study investigates the finite-amplitude meanders of shelfbreak fronts characterized by sloping isopycnals outcropping at both the surface and the shelfbreak ...

Abstract: bservations with fine horizontal resolution are used to identify the horizontal scales of variability over the Middle Atlantic Bight (MAB) shelf break and continental rise. Spray gliders collected observations along two ...

Abstract: Spring conditions at the shelf break in the Middle Atlantic Bight mark the transition period between the generally well-mixed shelf water in winter and the highly stratified shelf conditions during summer. A high-resolution ...

Abstract: In an attempt to understand whether local instabilities can account for the observed frontal variability in the Middle Atlantic Bight, a linear stability analysis was conducted for a wide range of background density and ...
