Oregon
Columbia River
Cape Blanco
Newport Hydrographic Line • Sampled biweekly for 20+ years (1996 – present)
– 7 stations
– 1 – 25 nm, seasonally out to 200 nm
• CTD, nutrients, chl-a, phytoplankton and HABs, zooplankton, ichthyoplankton

Thank you!
• 3 ocean projects to cover the various aspects of
ocean ecology
• Anomalous physical conditions can be strong
drivers of biological response
• Predator and prey data can be used directly in
management tools (e.g., Life Cycle Modeling)
