  1. The California Current Golden State, Green Ocean Lauren Weisel Physical Oceanography 2012

  2. Overview Location Eastern Boundary Currents Physical Characteristics Upwelling CANON Experiment CalCOFI Global Warming

  4. Eastern Boundary Currents Relatively shallow, broad, and slow-flowing Equatorward flow Upwelling Image source: *

  5. Physical Characteristics • 4 different water masses • Each with different properties

  6. Upwelling Ekman transport-driven Cold water drawn upwards Nutrient-rich Image source: http://www.scielo.cl/fbpe/img/rchnat/v77n3/img01-06.jpg

  8. CANON Experiment MBARI “Going with the flow” Picoplankton Nitrate vs. ammonia Image source: http://www.mbari.org/news/news_releases/2010/canon/canon_sept.html

  9. CalCOFI Founded in response to sardine fishing crisis Major researchers in eastern Pacific

  10. Global Warming Temperatures along California coast on the rise Zooplankton on the decline Anthropogenic?
