Dr. Jennifer Boldt

Research Scientist

Research in Coastal and Oceanic Ecosystems Science

Current research and/or projects

Research interests include:

  • pelagic ecosystem monitoring to detect change in the status and trends of pelagic fish (e.g., Pacific Herring), and to understand factors affecting the distribution, biomass, and trophodynamics of pelagic fish and prey species.
  • pelagic fish ecology to examine potential interactions between pelagic species and understand impacts of a changing climate on pelagic ecosystems.
  • ecosystem indicator development to contribute to State of the Ocean reporting, the assessment of the ecological impacts of environmental conditions at the ecosystem scale, the understanding of mechanistic linkages from physics to phytoplankton to zooplankton to fish, and the impacts of multiple stressors on ecosystem components.
