Phytoplankton composition is a critical component of aquatic food web structure, societally important fisheries, and human health. These internships are part of a larger project to test and evaluate phytoplankton remote sensing algorithms in the Northeast U.S. Continental Shelf Ecosystem. We are using in situ observations of phytoplankton and optical properties to optimize remote sensing algorithms of phytoplankton composition in the region. Working with other researchers, one intern would analyze phytoplankton imagery and compare the results with other environmental data. The second would aid in the analysis of optical observations to identify the spectral signatures used by satellite radiometers for discerning phytoplankton groups. Both interns will have the opportunity to aid in equipment maintenance, laboratory work, and if schedules allow, field work on a research cruise.
