Biochemical implications of the Bottom Boundary Layer Detachment at the Mid-Atlantic Bight shelf-break front.

ABSTRACT: The Mid-Atlantic Bight frontal system along the U.S. northeast shelf is rich in biodiversity. In this region, primary production is influenced by a variety of upwelling processes, including internal instabilities of the front, off-shore forcing from Gulf Stream rings, and wind-driven flows. It is noteworthy that the concentrations of chlorophyll-a ( Chl-a ) in the shelf-break region are not consistently enhanced throughout the year, although local increases of phytoplankton biomass have been observed in some circumstances. In this work, we investigate the frontal dynamics of one of the possible mechanisms affecting primary production: upwelling via detachment of the Bottom Boundary Layer (BBL). The annual variability of the surface Chl-a in the shelf-break region reveals a 5- to 20-
