Research focus: Physical Oceanography in high latitude seas; surface currents derived from satellite altimetry; sea surface salinity; remote sensing.


After a Master’s degree in physical oceanography from the University of Rhode Island’s Graduate School of Oceanography, John exchanged his New England roots for the slugs and moss of the Pacific Northwest. John joined ESR in 1996, transplanting across Lake Washington after 16 years at Science Applications International Corporation (SAIC) in Bellevue, WA. At SAIC he had significant experience with high latitude oceanography (studies in the Bering Sea, Weddell Sea, Scotia Sea, Chukchi and Beaufort Seas) as well as considerable work along the California coast (Santa Barbara Channel and Southern California Bight) and a study of the vertical structure of solitons in the Strait of Juan de Fuca.

At ESR, John’s interests in high latitude studies continued participating in the SCICEX, SOGLOBEC and SBI programs and expanded into various investigations utilizing satellite oceanography, including studies of the ENSO cycle using surface current EOF’s, satellite remote sensing of surface salinity (Aquarius/SAC-D Satellite Mission). John’s work also included mesoscale studies of ocean currents, temperature and salinity, applications of the acoustic Doppler current profiler and time variations with an eye on long-term variability.

John retired from active research in October, 2012. He retains an affiliate status with ESR.
