As a research scientist in the Coastal Biogeochemistry Group, Ms. Brandenberger manages programs involving trace metals speciation and monitoring in marine and freshwater environments. Her research programs are focusing on correlations between storm water loading of contaminants and land-use classifications, watershed scale contaminant mass balances, evaluating hypoxia trends over the last several hundred years in Puget Sound, and the atmospheric deposition of various toxics. She has a strong background in water quality issues and serves as the program manager for the watershed-scale contaminant loading program (Project ENVVEST) for Puget Sound Naval Shipyard on Sinclair/Dyes Inlet, Puget Sound, WA. In addition, Ms. Brandenberger is a Co-Principle Investigator on determining the historical trends in dissolved oxygen in the Puget Sound. She has experience in leading scientific teams to achieve program goals and deliverables. Ms. Brandenberger has over 15 years of trace metal chemistry experience and has taught many classes to students, industrial clients, U.S. Navy clients, and international programs.
- The biogeochemistry of trace elements in natural waters, with particular experience and interest in environmental and analytical studies concerning mercury, uranium, arsenic, selenium, molybdenum, rhenium, and selenium.
- Trace element analysis using ultra-clean laboratory and environmental sampling techniques.
- The chemical speciation of trace elements in natural waters.
- The reconstruction of historical trends using paleoecological indicators, organic biomarkers, and trace metals preserved in sediment cores.
- The characterization of storm-water contaminants, event mean concentrations, contaminant loading, and relationships with land-use classifications.
- The determination of contaminant mass balances for marine receiving waters and the proportion of atmospherically derived contaminants to the overall source budget.
