Two Positions: Optics and Biology
The Ocean Biology and Biogeochemistry Calibration and Validation Office (CVO) at the NASA/Goddard Space Flight Center (GSFC) (http://oceancolor.gsfc.nasa.gov/), is currently seeking an oceanographer to conduct studies in ocean color calibration and validation activities in optically complex waters. A variety of research inquiries will be required both in the field, to acquire data, and in the laboratory, to calibrate the field instruments and, subsequently, to analyze data and synthesize the results. Emphasis will be placed on coastal ocean observations from both field sampling and satellite remote sensing sources. The successful candidate should be willing to apply existing competence, acquire new capabilities, and, due to the multi-discipline approach to research at the CVO, be willing to collaborate with the existing CVO science team members to address problems associated with ocean color remote sensing in coastal ocean regions. Activities will include: a) measuring the apparent and inherent optical properties (AOPs and IOPs, respectively) of seawater in the field; b) processing the AOP and IOP data to geophysical units; c) applying processed AOP and IOP data to calibration and validation activities, in particular, matching up field observations with remote sensing parameters and deriving algorithmic relationships; d) performing statistical analysis of field and satellite data with an emphasis on developing quality assurance criteria to maintain calibration and validation uncertainty requirements (this endeavor will most likely benefit from the application of data classification and neural network techniques); and e) utilizing strong computer programming skills commensurate with data acquisition, formatting, processing, visualization, and analysis (items a-d). Ultimately, a more complete understanding of optically complex waters is expected to require radiative transfer modeling, thereby, any experience in the numerical implementation of radiative transfer processes will be beneficial.
The position requires a Ph.D. or M.S. in Physics, Oceanography, or a closely related
degree, and the applicant must be a U.S. citizen. Participation in scientific cruises is
necessary and previous research cruise and field data collection experience is
advantageous.

The Ocean Biology and Biogeochemistry Calibration and Validation Office (CVO) at the NASA/Goddard Space Flight Center (GSFC) (http://oceancolor.gsfc.nasa.gov/) is responsible for overseeing the execution of a comprehensive plan for the long-term calibration and validation of oceanic biological and biogeochemical satellite data, and is currently seeking an oceanographer with a strong background in biology. Due to the multi-discipline approach to research at the CVO, a variety of research skills, both in the field and the laboratory, will be needed to acquire data, analyze the observations, and synthesize the results. Emphasis will be placed on coastal and shallow-water processes, with a continuing evaluation of new insight with respect to the more established deep-ocean perspective. The CVO has prior established expertise in optical and chemical oceanography, and in order to address problems associated with ocean color remote sensing in coastal ocean regions, the successful candidate should have a willingness to participate in collaboration with the two formerly mentioned disciplines. The successful applicant should be willing to apply existing competence, acquire new capabilities, and collaborate with the existing CVO science team members to address the following scientific topics: a) dissolved organic carbon (DOC), and colored dissolved organic matter (CDOM); b) particle (phytoplankton) functional types (PFTs); c) phytoplankton growth rates and carbon biomass; d) particle size distribution; e) dissolved inorganic carbon (DIC) and alkalinity; and f) mixed layer depth. Joint activities with the other members of the CVO will include: a) publishing protocols and performance metrics; b) participating in instrument and analysis round robins; c) establishing standards and traceability for scientific methods; and d) coordinating international partnerships.
The position requires a Ph.D. or M.S. in Biology, Oceanography, or a closely related
degree, and the applicant must be a U.S. citizen. Experience in field research cruises and
data collection, and laboratory measurements and analyses of biological or chemical
properties of seawater, is required.
