Zooplankton taxa were counted in 8 to 19 samples from each of 11 cruises in the New York Bight between September 1974 and September 1975. Major seasonal events were an influx into the region of tropical-subtropical copepod species during autumm 1974 and summer 1975, an offshore (> 50 m water depth) zooplankton abundance maximum in March dominated by the pteropod Limacina retroversa, a second offshore maximum in May characterized by high abundance of the copepods Pseudocalanus sp, Calanus finmarchicus, and Oithona similis, and an offshore (> 50 m water depth) maximum in July characterized by high abundance of the copepods Centropages typicus and Temora longicornis. The offshore maxima occurred during or shortly after the local spring phytoplankton bloom (March-April). Advection of pteropod and copepod stocks into the region from the northeast probably contributed to these peaks. The July C. typicus-T. longicornis peak was associated with summer warming of the water column within the highly productive waters in the Bight apex and off the New Jersey coast. Comparison of our results with those of a study conducted in 1959-1960 shows that the most abundant species of copepods were essentially the same during the two periods.
