The California Current system (CCS) comprise two large regions, one subarctic from central California to British Columbia, and other subtropical from Point Conception, California to the tip of Baja California peninsula. To progress in the knowledge of the subtropical part of the CCS, was created the IMECOCAL program, which means “Mexican Research of the California Current”. The data base presented here is a product of the zooplankton collection during ten IMECOCAL cruises. Zooplankton samples were collected with oblique net tows in the upper 200 m (or from 10 m above the sea floor in shallow stations), using a Bongo net of 500 µm mesh width and mouth diameter of 0.7 m. Four cruises correspond to the four seasons of 2005 and the rest are summer cruises preformed during 2002-2008. Hyperiid amphipods were identified using mainly the taxonomic key for Hyperiidea of the world oceans (Vinogradov et al., 1996). The total number of samples analyzed were 482 but hyperiids were absent in 18. The positive samples were ...
