Plankton studies in San Francisco Bay; V, Zooplankton species composition and abundance in the South Bay, 1980-1981

Data are presented that summarize zooplankton species composition and abundance in South San Francisco Bay during 1980 and 1981. Sampling was conducted at least twice monthly at thirteen stations, from the southern extremity of the South Bay to the Golden Gate Bridge between January 1980 and May 1981. Samples were collected by pump at three depths in the shipping channel and one depth over the shoals. Subsamples were enumerated while alive. Total zooplankton biomass as carbon was calculated from estimated carbon quotas and abundances of each organism enumerated.
