Evidence of the California Undercurrent in CTD Data LT Mike Cornelius OC3570 19 March 2003

Original Plan: Analyze CTD data to see if intrusive mixing caused a sound speed increase closer to shore. Not so good. Revised Plan: Analyze CTD data to see if there are indications of the warmer, more saline water brought poleward by California Undercurrent.

California Undercurrent Studied by Ramp 1997, Sakura 1996 Northward flow of warmer, more saline water at a predominant depth of 100-300m Could I find evidence of California Undercurrent in CTD data from cruise??

Conclusions: Evidence of the California Undercurrent was definitely present in the CTD data collected on our cruise. An interesting thesis topic would be to analyze data further south of San Luis Obispo to see the differences in the profiles.
