Abstract

In July 1988, upper layer zooplankton biomass in and around a major cold filament off Point Arena, California, declined inshore to offshore, but relatively high levels extended seaward along the cool side of the filament jet. The cross-filament compositional sequence was characterized by local maxima of Dolioletta gegenbauri in nonfilament waters to the S and E, Euphausia pacifica along the SE margin of the filament, Eucalanus californicus and euphausiid larvae within the cool core of the filament and extending partway across the strong seaward jet on the N and W margin of the filament, and heteropod larvae, chaetognaths, Dolioletta, and a mixture of small copepods along the warm side of the jet and extending into nonfilament waters to the N and W. -from Authors
