Evidence of the California Undercurrent in CTD
Data

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.

• 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.

Final Conclusion Listen to Professor Guest, he
is a wise man when it comes to not
procrastinating this project!
Why put off until tomorrow what you can do the
day after tomorrow
