Distribution of Phytoplankton in California
Types of distributionRegional distribution
Vertical distribution (depth)
Factors influencing distribution off the coast of CaliforniaUpwellingContinental shelf processes Davidson currentCalifornia currentEl Nino eventsSeason and photoperiod
Trends in distribution in CaliforniaCan be separated into inshore and offshore
groups (Venrick, 1998)Large annual variation in productivityHigher productivity is associated with more
intense upwellingLatitudinal variability in groups present
Commonly occurring genera distance from shore(Venrick, 1998)Inshore : Chaetoceros, Skeletonema, Pseudo-
nitzschia, EmilianiaOffshore: Emiliania, Gephyrocapsa, Nitzschia,
Fragilariopsis
Vertical distributionInfluenced by thermocline, light penetration
and mixing
