      RAFOS float trajectories near the 27.5 density level were analyzed to investigate discrete eddies in the northern North Atlantic with the objective of determining their geographical distribution and characteristics. ...
    • Dispersal and population connectivity in the deep North Atlantic estimated from physical transport processes 

      Etter, Ron J.; Bower, Amy S. (2015-06)
      Little is known about how larvae disperse in deep ocean currents despite how critical estimates of population connectivity are for ecology, evolution and conservation. Estimates of connectivity can provide important ...
    • The dispersal of dense water formed in an idealized coastal polynya on a shallow sloping shelf 

      Zhang, Weifeng G.; Cenedese, Claudia (American Meteorological Society, 2014-06)
      This study examines the dispersal of dense water formed in an idealized coastal polynya on a sloping shelf in the absence of ambient circulation and stratification. Both numerical and laboratory experiments reveal two ...

      Knapp, George P.; Stalcup, Marvel C.; Stanley, Robert J. (Woods Hole Oceanographic Institution, 1989-07)
      This report describes a modified Winkler titration technique that has been used for the past 25 years at the Woods Hole Oceanographic Institution (WHOI). During this time most of the dissolved oxygen measurements made at ...
    • Distribution and diel vertical movements of mesopelagic scattering layers in the Red Sea 

      Klevjer, Thor A.; Torres, Daniel J.; Kaartvedt, Stein (Springer, 2012-06-13)
      The mesopelagic zone of the Red Sea represents an extreme environment due to low food concentrations, high temperatures and low oxygen waters. Nevertheless, a 38 kHz echosounder identified at least four distinct ...
    • The distribution of dissolved silica in the deep western North Atlantic Ocean 

      Needell, Gerald J. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1978-11)
      The distribution of dissolved silica in the deep western North Atlantic Ocean is presented. The potential temperature-dissolved silica relationship is compared with the potential temperature salinity relationship in the ...
