Physical Characteristics • 4 different water masses • Each with different properties
Upwelling Ekman transport-driven Cold water drawn upwards Nutrient-rich Image source: http://www.scielo.cl/fbpe/img/rchnat/v77n3/img01-06.jpg

CalCOFI Founded in response to sardine fishing crisis Major researchers in eastern Pacific
Global Warming Temperatures along California coast on the rise Zooplankton on the decline Anthropogenic?
