In April 1979 a vigorous diatom bloom covering an area of more than 1000 km2
occupied the cold core of upwelled water, in the region of the 200 m isobath. Primary
productivity throughout the year in this region averaged about 2 g C m−2 d−1
(Yoder et al. 1981, 1983). Strong southwesterly winds were found to cause Ekman
offshore transport that favored both the formation of an offshore meander of
the Gulf Stream and the inshore movement of upwelled water at intermediate
depths, to compensate for the offshore transport of the surface layer (Atkinson
et al. 1984). It is now thought that this upwelling caused by the meandering offshore
of the Gulf Stream is the primary mechanism for providing nutrients and
stimulating production on the outer continental shelf of the southeastern United
States south of Cape Hatteras. Such enrichment may explain why the shelf break
south of Cape Hatteras is a breeding center for Atlantic menhaden Brevoortia
tyrannus and for bluefish Pomatomus saltatrix (Atkinson and Targett 1983). Haney
(1986) found that the shearwaters Puffinus gravis and Calonectris diomedea and the
storm-petrels Oceanites oceanicus and Oceanodroma castro were most abundant in
the upwelled cold core of frontal eddies, while the black-capped petrel Pterodroma
hasitata and the bridled tern Sterna anaethetus were most abundant in the oligotrophic
warm filament inshore of the cold core. North of Cape Hatteras the Gulf Stream
moves away from the coast and instead of cold-core frontal eddies we find
warm-core ring formation on the shoreward side of the current (see Section 8.4.2).
