    My career has focused on ocean color remote sensing research since 1998 in a number of settings including government laboratories, the private sector, and academia.

    Research Interests

    Estuarine Circulation Mapping and Structure Modeling

    Observing and modeling transverse-vertical structure, residual circulation, and exchange transport in Long Island Sound from a multi-year ferry observatory.

    Ocean Color in a Complex Estuary

    Developing ocean color remote sensing algorithms for the retrieval of inherent optical properties in the complex waters of Long Island Sound.

    Resolving Ocean Color in Complex, Coastal Systems

    This research focused on overcoming the many hurdles in retrieving accurate ocean color from legacy satellite instruments such as MODIS and SeaWiFS in complex, turbid, near-shore waters. Specialized atmospheric correction approaches were introduced and validated in target regions including the Amazon River Plume, Chesapeake Bay, Mississippi River Plume, and the Yangtze River Plume, and scales of variability in bio-optical properties were evaluated for making recommendations on spatial resolution of future missions.

    Global Ocean Carbon Algorithm Database (GOCAD) and its Application

    A Global Ocean Carbon Algorithm Database (GOCAD) was been developed from over 500 oceanographic field campaigns conducted worldwide over the past 30 years including in situ reflectances and coincident satellite imagery, Chromophoric Dissolved Organic Matter (CDOM) absorption coefficients, CDOM spectral slopes, dissolved and particulate organic carbon (DOC and POC, respectively), and inherent optical, physical, and biogeochemical properties. Algorithms for the remote sensing of CDOM, CDOM spectral slope, and dissolved organic carbon (DOC) in the global ocean were developed using in situ reflectances, and validated with satellite match-ups of MODIS and SeaWiFS imagery.

    Current Projects

    Hyperspectral In Situ Support for PACE (HyperInSPACE)

    Develop modular, open-source, platform independent software for quality control and processing of autonomous, in situ, above-water radiometry. Radiometry is to be processed using the latest protocols and research in above-water methodologies including incorporation of hyperspectral (ir)radiances and sky/sun glint corrections, polarization, and comprehensive solar-sensor geometry, meteorological flag, and ship attitude filtering. HyperInSPACE will be applied to research topics including processing backlogs of HyperSAS data from oceanographic cruises between 2015 and 2019, ocean color product algorithm development, and orbital platform validation.

    Commercial Satellite Imagery Evaluation

    Evaluate the utility of high spatial resolution commercially available satellite data for conducting ocean color research.

    Positions/Employment

    9/2018 - Present

    Research Scientist

    Universities Space Research Association, Goddard Space Flight Center

    Conduct research directed at understanding ocean optics, biogeochemistry and ecosystem dynamics including high spatial and temporal variability. This research will emphasize the marine carbon cycle and the interactions and feedbacks between biological (e.g., primary production), chemical (e.g., organic carbon and nutrient balances and fluxes), and physical processes (river discharge, mixed layer dynamics, circulation, etc.) and entails working with optical and chemical field data sets, satellite data products from various sensors, and model results. The scope of the work includes processing and analysis of in situ radiometric measurements, satellite data processing and analysis, and radiative transfer simulations. Research activities involve the development and evaluation of satellite products for existing satellite sensors and in preparation for the PACE mission and participation in field campaigns. This research is conducted in support of the NASA Ocean Biology and Biogeochemistry Program.
