    Berloff, Pavel S. (Cambridge University Press, 2005-04-01)
    The role of mesoscale oceanic eddies in driving large-scale currents is studied in an eddy-resolving midlatitude double-gyre ocean model. The reference solution is decomposed into large-scale and eddy components in a way ...
  • Range compensation for backscattering measurements in the difference-frequency nearfield of a parametric sonar 

    Foote, Kenneth G. (Acoustical Society of America, 2012-05)

    When Victor Hensen deployed the first true plankton1 net in 1887, he and his colleagues were attempting to answer three fundamental questions: What planktonic organisms are present in the ocean? How many of each type ...
  • Rapid analysis of 13C in plant-wax n-alkanes for reconstruction of terrestrial vegetation signals from aquatic sediments

    Long-chain, odd-carbon-numbered C25 to C35 n-alkanes are characteristic components of epicuticular waxes produced by terrestrial higher plants. They are delivered to aquatic systems via eolian and fluvial transport and are ...
  • Rapid and gradual modes of aerosol trace metal dissolution in seawater 

    Mackey, Katherine R. M.; Chien, Chia-Te; Post, Anton F.; Saito, Mak A.; Paytan, Adina (Frontiers Media, 2015-01-21)
    Atmospheric deposition is a major source of trace metals in marine surface waters and supplies vital micronutrients to phytoplankton, yet measured aerosol trace metal solubility values are operationally defined, and there ...
  • Rapid change in freshwater content of the Arctic Ocean 

    McPhee, M. G.; Proshutinsky, Andrey; Morison, James H.; Steele, Michael; Alkire, M. B. (American Geophysical Union, 2009-05-21)
    The dramatic reduction in minimum Arctic sea ice extent in recent years has been accompanied by surprising changes in the thermohaline structure of the Arctic Ocean, with potentially important impact on convection in the ...
  • Rapid circulation of warm subtropical waters in a major glacial fjord in East Greenland 

    Straneo, Fiamma; Hamilton, Gordon S.; Sutherland, David A.; Stearns, Leigh A.; Davidson, Fraser J. M.; Hammill, Mike O.; Stenson, Garry B.; Rosing-Asvid, Aqqalu (2009-12-17)
    The recent rapid increase in mass loss from the Greenland Ice Sheet is primarily attributed to an acceleration of outlet glaciers. One possible cause is increased melting at the ice/ocean interface driven by the synchronous ...
  • Rapid decline of the CO2 buffering capacity in the North Sea and implications for the North Atlantic Ocean 

    Thomas, Helmuth; Prowe, A. E. Friederike; van Heuven, Steven; Bozec, Yann; Baar, Hein J. W. de; Schiettecatte, Laure-Sophie; Suykens, Kim; Kone, Mathieu; Borges, Alberto V.; Lima, Ivan D.; Doney, Scott C. (American Geophysical Union, 2007-10-06)
    New observations from the North Sea, a NW European shelf sea, show that between 2001 and 2005 the CO2 partial pressure (pCO2) in surface waters rose by 22 μatm, thus faster than atmospheric pCO2, which in the same period ...
  • Rapid dispersal of a hydrothermal plume by turbulent mixing 

    Walter, Maren; Mertens, Christian; Stober, Uwe; German, Christopher R.; Yoerger, Dana R.; Sultenfuß, Jurgen; Rhein, Monika; Melchert, Bernd; Baker, Edward T. (2010-08-23)
    The water column imprint of the hydrothermal plume observed at the Nibelungen field (8°18' S 13°30' W) is highly variable in space and time. The off-axis location of the site, along the southern boundary of a non-transform ...
