  • An oceanic current against the wind : how does Taiwan island steer warm water into the East China Sea? 

    Yang, Jiayan (American Meteorological Society, 2007-10)
    Along the Taiwan Strait (<100 m in depth) a northeastward flow persists in all seasons despite the annually averaged wind stress that is strongly southwestward. The forcing mechanism of this countercurrent is examined by ...
  • Oceanic evidence of climate change in southern Australia over the last three centuries 

    Thresher, Ronald E.; Rintoul, Stephen R.; Koslow, J. Anthony; Weidman, Christopher R.; Adkins, Jess F.; Proctor, Craig (American Geophysical Union, 2004-04-13)
    Chemical analysis of deepwater octocorals collected at 1000 m depth off southern Australia indicates long-term cooling, beginning in the mid-18th century. This cooling appears to reflect shoaling of isotherms along the ...

    Macdonald, Alison M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1995-08)
    Data from fifteen globally distributed, modern, high resolution, hydrographic oceanic transects are combined in an inverse calculation using large scale box models. The models provide estimates of the global meridional ...
  • Oceanic heterotrophic bacterial nutrition by semilabile DOM as revealed by data assimilative modeling 

    Luo, Ya-Wei; Friedrichs, Marjorie A. M.; Doney, Scott C.; Church, Matthew J.; Ducklow, Hugh W. (Inter-Research, 2010-08-03)
    Previous studies have focused on the role of labile dissolved organic matter (DOM) (defined as turnover time of ~1 d) in supporting heterotrophic bacterial production, but have mostly neglected semilabile DOM (defined as ...

    Lvov, Yuri V.; Polzin, Kurt L.; Tabak, Esteban G.; Yokoyama, Naoto (American Meteorological Society, 2010-12)
    Steady scale-invariant solutions of a kinetic equation describing the statistics of oceanic internal gravity waves based on wave turbulence theory are investigated. It is shown in the nonrotating scale-invariant limit that ...
  • Oceanic lithosphere magnetization : marine magnetic investigations of crustal accretion and tectonic processes in mid-ocean ridge environments 

    Williams, Clare M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2007-09)
    The origin of symmetric alternating magnetic polarity stripes on the seafloor is investigated in two marine environments; along the ridge axis of the fast spreading East Pacific Rise (EPR) (9º 25’-9º 55’N) and at Kane ...
  • Oceanic microstructure observed near Bermuda using a towed sensor 

    Magnell, Bruce Arthur (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1973-06)
    Many hypotheses have been advanced to explain the formation of mixed layers in the ocean; the salt finger type of double-diffusive convection, in particular, has received much attention. Because of their uniquely ordered ...
