Research Activities

  • PI, “An Integrated Terrestrial-Coastal Ocean Observation and Modeling Framework for Carbon Management Decision Support" (collaborative project with Auburn University, University of Delaware, and North Carolina State University) NASA, $1.2M over three years ($228K to UMass Dartmouth)
  • PI, “Research and Education in Quantitative Fisheries and Ecosystem Science,” NOAA (subaward through the Woods Hole Oceanographic Institution), $360K over three years

Research Interests

  • Biological distributions and productivity
  • Cycling of carbon and nutrients in coastal and ocean waters using ship-based measurements and optical and remotely sensed observations
  • Characterization of land-ocean interactions using coupled ecosystem models to assess impacts of climate and land use change
  • Optical assessment of air-sea carbon fluxes in river-dominated margins
  • Optical detection and assessment of harmful algal blooms
