The Habitat Assessment and Marine Chemistry Program conducts research on chemical and ecological processes that occur in marine, tidal, and watershed habitats ranging from the Arctic to the Gulf of Alaska. This program attempts to assess bioenergetics in various species and life stages, assess the impact of development and contaminants on these species and their habitats, and map and evaluate their habitat quality. The program comprises a mix of chemists and biologists focused into three project teams:
Nutritional ecology research or bioenergetics, assesses the nutritional value of forage species, including juvenile salmon, as measured by changes in lipid class, fatty acid, and caloric composition of these forage species. The studies seek to evaluate how habitat quality changes seasonally and spatially by understanding how prey organisms allocate energy between growth, reproduction, and fat storage.
Contaminants research quantifies threats from polycyclic aromatic hydrocarbons (PAH) to reproductive, nursery, and feeding habitats for various life stages of salmon, herring, and other fish species. Much of this work has focused on understanding the long-term effects of the
Exxon Valdez Oil Spill.
Nearshore habitat research combines habitat mapping and fish utilization studies to identify use of essential fish habitat. Additional focus has been on identifying sensitive life stages of forage fish and chemical or physical impacts of development on the quality of eelgrass and kelp bed habitats.
FEDZ Lab research supports studies on the biology, trophic ecology, and bioenergetics of juvenile salmon and associated fishes, along with how they interact in ecosystems during their early marine life history. The goal is to better understand recruitment mechanisms and processes that describe growth and survival of these populations relative to their prey, predators, and potential competitors. Sample processing in the FEDZ lab focuses on measurements of fish size, energy density, and diet and feeding success of juvenile salmon and associated fishes, as well as the abundance and composition of their zooplankton prey fields.
