“…The CC and the CCC are parts of the California Current system extending 1000 km from offshore Oregon to Baja California (Miller et al, 1999). The CC system is modulated across various time scales by (i) ENSO with a pseudofrequency of ∼2 to 7-8 yr, (ii) the PDO with a bidecadaltridecadal frequency of ∼20 to 30 yr, and (iii) by pentadecadal variability of ∼50 to 75 years (Lluch-Belda et al, 2003;Minobe, 2000).…”

Abstract. The varved sedimentary AD 1917 record from the depositional center of the Santa Barbara Basin (SBB, California) was analyzed with monthly to triannual resolution to yield relative abundances of six coccolithophore species representing at least 96% of the coccolithophore assemblage. Seasonal/annual relative abundances respond to climatic and surface hydrographic conditions in the SBB, whereby (i) the three species G. oceanica, H. carteri and F. profunda are characteristic of the strength of the northward flowing warm California Counter Current, (ii) the two species G. ericsonii and G. muellerae are associated with the cold equatorward flowing California Current, (iii) and E. huxleyi appears to be endemic to the SBB. Spectral analyses on relative abundances of these species show that all are influenced by the El Niño Southern Oscillation (ENSO) and/or by the Pacific Decadal Oscillation (PDO). Increased relative abundances of G. oceanica and H. carteri are associated with warm ENSO events, G. muellerae responds to warm PDO events and the abundance of G. ericsonii increases during cold PDO events. Morphometric parameters measured on E. huxleyi, G. muellerae and G. oceanica indicate increasing coccolithophore shell carbonate mass from ∼1917 until 2004 concomitant with rising pCO 2 and sea surface temperature in the region of the SBB.

“…These programs include Coastal Ocean Dynamics Experiment (CODE) [see Beardsley and Lentz, 1987] Their focus includes the structure and dynamics of shelf flows, coastal eddies, and offshore filaments; the poleward undercurrent and its variability; and the relationship between these ocean features and bio-geo-chemical activity in the region. A brief review of the CC relevant to the present study is given by Miller et al [1999].…”

“…White abalone behavior may be a mechanism that results in their presence on drift algae with other species of benthic molluscs, holothurians, and arthropods that use this substrate as a dispersal mechanism in the Santa Barbara Channel and Southern California Bight (Bushing 1994, Hobday 2000a. Water velocities within the California Current System may exceed 20 cm s -1 during spring conditions (Nishimoto & Washburn 2002) and nearshore eddies can exceed 30 to 45 cm s -1 in the Southern California Bight (Sverdrup et al 1947, Anonymous 1991, Winant et al 1991, Miller et al 1999 . At this speed, abalone that stayed on the kelp from 30 to 51 d could possibly be transported from 389 to 661 km.…”
