  • An ectobiont-bearing foraminiferan, Bolivina pacifica, that inhabits microxic pore waters : cell-biological and paleoceanographic insights 

    Bernhard, Joan M.; Goldstein, Susan T.; Bowser, Samuel S. (2009-08-17)
    The presence of tests (shells) in foraminifera could be taken as an indicator that this protist taxon is unlikely to possess ectosymbionts. Here, however, we describe an association between Bolivina pacifica, a foraminiferan ...
  • Eddies and an extreme water mass anomaly observed in the eastern south Pacific at the Stratus mooring 

    Stramma, Lothar; Weller, Robert A.; Czeschel, Rena; Bigorre, Sebastien P. (John Wiley & Sons, 2014-02-12)
    In the tropical eastern South Pacific the Stratus Ocean Reference Station (ORS) (∼20°S, 85.5°W) is located in the transition zone between the oxygen minimum zone (OMZ) and the well-oxygenated subtropical gyre. In February/March ...
  • Eddies and friction : removal of vorticity from the wind-driven gyre 

    Fox-Kemper, Baylor (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2003-06)
    Inertial terms dominate the single-gyre ocean model and prevent western-intensification when the viscosity is small. This occurs long before the oceanically-appropriate parameter range. It is demonstrated here that the ...

    Timmermans, Mary-Louise; Toole, John M.; Proshutinsky, Andrey; Krishfield, Richard A.; Plueddemann, Albert J. (American Meteorological Society, 2008-01)
    Five ice-tethered profilers (ITPs), deployed between 2004 and 2006, have provided detailed potential temperature θ and salinity S profiles from 21 anticyclonic eddy encounters in the central Canada Basin of the Arctic ...
  • Eddy dynamics of ß plumes 

    Kida, Shinichiro (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2003-09)
    The importance of eddies and nonlinearities in ß-plume dynamics in the deep ocean was investigated using reduced gravity models of the deep ocean forced by a small region of cross isopycnal transport in the interior. The ...
  • Eddy forcing of the mean circulation in the western North Atlantic 

    Brown, Ellen Dunning (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1984-08)
    This thesis addresses several aspects of the problem of determining the effect of the low-frequency eddy variability on the mean circulation of the Western North Atlantic. A framework for this study is first established ...
  • Eddy formation near the west coast of Greenland 

    Bracco, Annalisa; Pedlosky, Joseph; Pickart, Robert S. (American Meteorological Society, 2008-09)
    This paper extends A. Bracco and J. Pedlosky’s investigation of the eddy-formation mechanism in the eastern Labrador Sea by including a more realistic depiction of the boundary current. The quasigeostrophic model consists ...
  • Eddy generation at a convex corner by a coastal current in a rotating system 

    Klinger, Barry A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1992-03)
    Rotating baroclinic and barotropic boundary currents flowing around a corner in the laboratory were studied in order to discover the circumstances under which eddies were produced at the corner. Such flows are reminiscent ...
  • Eddy stirring and horizontal diffusivity from Argo float observations : geographic and depth variability 

    Cole, Sylvia T.; Wortham, Cimarron J. L.; Kunze, Eric; Owens, W. Brechner (John Wiley & Sons, 2015-05-21)
    Stirring along isopycnals is a significant factor in determining the distribution of tracers within the ocean. Salinity anomalies on density surfaces from Argo float profiles are used to investigate horizontal stirring and ...
  • Eddy stirring in the Southern Ocean 

    Naveira Garabato, Alberto C.; Ferrari, Raffaele; Polzin, Kurt L. (American Geophysical Union, 2011-09-17)
    There is an ongoing debate concerning the distribution of eddy stirring across the Antarctic Circumpolar Current (ACC) and the nature of its controlling processes. The problem is addressed here by estimating the isentropic ...
  • Eddy transport of organic carbon and nutrients from the Chukchi Shelf : impact on the upper halocline of the western Arctic Ocean 

    Mathis, Jeremy T.; Pickart, Robert S.; Hansell, Dennis A.; Kadko, David; Bates, Nicholas R. (American Geophysical Union, 2007-05-04)
    In September 2004 a detailed physical and chemical survey was conducted on an anticyclonic, cold-core eddy located seaward of the Chukchi Shelf in the western Arctic Ocean. The eddy had a diameter of ∼16 km and was centered ...
  • Eddy-driven pulses of respiration in the Sargasso Sea 

    Mourino-Carballido, Beatriz (2009-02)
    An analysis of nine years of data from the NW subtropical Atlantic reveals that variability in heterotrophic processes associated with (sub)mesoscale features has a major impact on the balance between photosynthesis and ...
  • Eddy-driven sediment transport in the Argentine Basin : is the height of the Zapiola Rise hydrodynamically controlled? 

    Weijer, Wilbert; Maltrud, Mathew E.; Homoky, William B.; Polzin, Kurt L.; Maas, Leo R. M. (John Wiley & Sons, 2015-03-27)
    In this study, we address the question whether eddy-driven transports in the Argentine Basin can be held responsible for enhanced sediment accumulation over the Zapiola Rise, hence accounting for the existence and growth ...
  • Eddy-induced particle dispersion in the near-surface North Atlantic 

    Rypina, Irina I.; Kamenkovich, Igor V.; Berloff, Pavel S.; Pratt, Lawrence J. (American Meteorological Society, 2012-12)
    This study investigates the anisotropic properties of the eddy-induced material transport in the near-surface North Atlantic from two independent datasets, one simulated from the sea surface height altimetry and one derived ...
