Spatial Coverage: Pacific Ocean, California Current, Baja California Temporal Coverage: July 15-30, 1998 Language: Spanish Summary: Biomass and abundance of major zooplankton groups are reported in this paper as ml/1000m3 and #/m3 respectively. Sixty-five stations were sampled using a 500um Bongo net. For analysis, individuals whose volume was greater than 5 ml were removed. Detailed contour plots of species distribution are included in the back of the report.
