Presentation Title:
Linkages Between Climate Variation and the Pelagic Ecosystem of the California Current

Desription of Presentation:
We present the findings of a structured data exploration relating productivity of a sentinel trophic chain in central California Current to local- and large-scale variability in the ocean environment. We note specific coastal environmental conditions that force productivity of krill, forage fish, seabirds, and salmon and explore the possibility of recent shifts in these relationships. Finally, we note a possible monotonic decline in the productivity of the system over the last thirty years.

Presenter's Biography:
My graduate training was in fishery science and ecology. I worked on the east coast on numerous fished resources, largely, performing stock assessment and stock discrimination work. Following graduate training, I was employed as a National Academy of Sciences postdoctoral fellow with NOAA at Woods Hole. Specific projects before arriving at NOAA Fisheries, Santa Cruz included otolith age and growth studies, otolith microchemical studies, reproductive ecology, basic stock assessment, and environmental forcing of Atlantic salmon maturation and growth. While at NOAA Fisheries, Santa Cruz, my work has focused on the relationships between the ocean environment and salmon and ecosystem productivity.
