Presentation Transcript

  1. Mean Annual Ekman Transport vs. Mean Annual Chlorophyll Along Pacific Coast Upwelling-favorable Ekman transport Chlorophyll Ware and Thomson, Science, 2005

  2. Trophic Link between Chl and Fish along Pacific Coast Ware and Thomson, Science, 2005

  3. Trophic Links off British Columbia Chlorophyll and Zooplankton Zooplankton and Fish Ware and Thomson, Science, 2005

  4. Seasonal Cycle of Chlorophyll in California Current System Fig., A. Thomas, Univ. Maine

  5. June Euphausiid Egg Density More Euphausiids generally found offshore of or north of the Columbia outflow Slide courtesy of Bill Peterson and Cheryl Morgan, Oregon State U. and NOAA

  6. Traditional View of Columbia Plume Orientation Not much opportunity for plume effects to the north here! Hickey et al., CSR, 2005

  7. Updated View of the Columbia Plume in Spring/Summer: SW and N or NNW simultaneously North branch of plume present 50-70% of time in summer Stability? Retention shoreward of plume? Hickey et al., CSR, 2005

  8. How do we get plumes in 2 directions at once? Applies primarily to rivers where receiving waters flow in opposite direction to Coriolis tendency Hickey et al., CSR, 2005

  9. Export of Nutrients from Juan de Fuca Region Nitrate at 15 m
