My work focuses on water clarity at local, regional, and global scales. At local scales, my most recent field research focuses on how oysters in aquaculture settings mediate hydrodynamics, suspended particle characteristics, and water clarity. At regional scales, I investigate long term trends in Chesapeake Bay water clarity using observations and numerical modeling. I combine three methods to evaluate how water clarity has declined and potentially improved: a cruise-based dataset, satellite data, and 3D numerical modeling with the ChesROMS estuarine carbon and biogeochemistry (ECB) model. At global scales, I study marine particles as seen by optical imaging devices. For my M.S. work, I studied particle characteristics using the Underwater Vision Profiler (UVP) which photographs and sizes marine particles to investigate the total potential particulate carbon flux to depth.
