    The Changjiang River (CR) is divided into a southern branch (SB) and a northern branche (NB) by Chongming Island as the river enters the East China Sea. Observations reveal that during the dry season the saltwater in the ...
  • Sands and environmental conditions impact the abundance and persistence of the fecal indicator bacteria Enterococcus at recreational beaches 

    Halliday, Elizabeth (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2012-09)
    The marine fecal indicator Enterococcus is measured at beaches to detect fecal contamination events, and beaches are closed to bathers when Enterococcus is found to exceed the federally mandated limit. This dissertation ...

    Inorganic phosphorus (SRP) concentrations in the subtropical North Atlantic are some of the lowest in the global ocean and have been hypothesized to constrain primary production. Based upon data from several transect cruises ...
  • Satellite data processing system (SDPS) users manual V1.0 

    Caruso, Michael J.; Dunn, Christopher V. R. (Woods Hole Oceanographic Institution, 1989-05)

    Evans, R.; Baker, Karen S.; Brown, O.; Smith, Raymond C.; Hooker, Stanford B.; Olson, Donald B.; Warm Core Rings Program Service Office (Woods Hole Oceanographic Institution, 1984-01)
    A chronology constructed from satellite-derived thermal imagery is presented to describe the formation and life history of warm-core ring 82-B. A comparison is made with warm-core ring 81-F in order to illustrate similarities ...
  • Satellite observations of chlorophyll, phytoplankton biomass, and Ekman pumping in nonlinear mesoscale eddies 

    Gaube, Peter; Chelton, Dudley B.; Strutton, Peter G.; Behrenfeld, Michael J. (John Wiley & Sons, 2013-12-02)
    Nonlinear mesoscale eddies can influence biogeochemical cycles in the upper ocean through vertical and horizontal advection of nutrients and marine organisms. The relative importance of these two processes depends on the ...
  • Satellite observations of mesoscale eddy-induced Ekman pumping 

    Gaube, Peter; Chelton, Dudley B.; Samelson, Roger M.; Schlax, Michael G.; O’Neill, Larry W. (American Meteorological Society, 2015-01)
    Three mechanisms for self-induced Ekman pumping in the interiors of mesoscale ocean eddies are investigated. The first arises from the surface stress that occurs because of differences between surface wind and ocean ...
