2016 Zooplankton sampling in San Joaquin River and False River near Jersey Island in the Sacramento-San Joaquin River Delta of Contra Costa County, California, USA (ver. 2.0, April 2020)

This data set contains information on zooplankton and associated environmental parameters for sampling conducted in the San Joaquin River and False River near their confluence at Jersey Point (Contra Costa County, California), during February-March, 2016. Macrozooplankton were sampled with vertical tows (bottom to surface) of a 50 cm-diameter conical plankton net that was 150cm long with 102µm mesh. Samples were preserved in the field in 10% formalin for laboratory processing that was conducted by a contractor (EcoAnalysts, Inc).
