Seasonal variations in the phytoplankton community, particularly in meroplanktonic dinoflagellates and physico-chemical characteristics of the water column during the sediment collection period were described by Morquecho and Lechuga-Deveze (2004).
Slackening of the current will allow meroplanktonic species to penetrate nearer to the coast, increasing species competition or leading to the dispersal and possible loss of coastal species.
Meroplanktonic larvae become entrained in these offshore-moving surface currents and accumulate at fronts where this upwelled water meets the offshore, southward-flowing water of the California Current (Roughgarden et al.
