Biological Characteristics of the CINMS

Numerous species have unique distributional boundaries that often coincide with oceanographic conditions and characteristics. These boundaries define biophysical regions called bioprovinces. Because of the unique ocean patterns in the SBC, the CINMS straddles three provinces: depending on the prevailing SBC circulation, the waters of San Miguel, and most of Santa Rosa are characterized as a cold temperate (Oregonian Province) bioprovince; the waters off Santa Barbara Island, Anacapa Island, and the eastern half of Santa Cruz Island are characterized as warm temperate (Californian Province); in between, there is a "Transition" Province which has properties resulting from the mixture of cold and warm water masses. Thus, CINMS species are often grouped into two primary faunal regimes: those species associated with cold water masses and those species associated with warm water masses. These regimes often shift depending on the strength of upwelling in the Pt. Arguello-Pt. Conception area as well as the strength of the SCC (McGinnis, 2001).
