Jeremy Werdell @ NASA Goddard Space Flight Center

PACE Project Scientist & Oceanographer in the Ocean Biology Processing Group (616) at Goddard Space Flight Center

My so-called "expertise" lies in the realm of ocean color satellites and bio-optical remote sensing. Specifically: the on-orbit calibration of these satellites and the validation of their data products; the development and evaluation of marine bio-optical algorithms; the collection and analysis of in situ biogeochemical oceanographic measurements; and the assimilation of the above to study how the global ocean and various regional ecosystems are changing with time. I occasionally sneak away from the office to teach or act as a student mentor, or escape completely to present our work and ongoing analyses. While recuperating from such scientific endeavors or unable to sail upon favorite locales, I remain dedicated to maritime pursuits by preparing and consuming significant quantities of local fish and shellfish.
