  • Oceanographic pursuit : networked control of multiple vehicles tracking dynamic ocean features 

    Reed, Brooks L.; Hover, Franz S. (Elsevier, 2014-05-29)
    We present an integrated framework for joint estimation and pursuit of dynamic features in the ocean, over large spatial scales and with multiple collaborating vehicles relying on limited communications. Our approach uses ...
  • Oceanographic study of warm core Gulf Stream rings and the Northwest Atlantic Slope Water region : a prospectus for multidisciplinary research, report and proceedings / Interdisciplinary Workshop on Gulf Stream Anticyclonic Eddies (Warm Core Rings) held at the Woods Hole Oceanographic Institution, May 16-20, 1977 

    Unknown author (Woods Hole Oceanographic Institution, 1977-05)
    It is well recognized in the oceanography of the Western North Atlantic that a distinct hydrographic regime exists between the continental shelf and the Gulf Stream, once the latter has effectively separated from the ...
  • Oceanography : oxygen and climate dynamics 

    Doney, Scott C.; Karnauskas, Kristopher B. (Nature Publishing Group, 2014-09)
    Low oxygen levels in tropical oceans shape marine ecosystems and biogeochemistry with climate change expected to expand these regions. Now, a study indicates that regional dynamics control trop ...
  • Oceanography : plankton in a warmer world 

    Doney, Scott C. (2006-12)
    Satellite data show that phytoplankton biomass and growth generally decline as the oceans’ surface waters warm up. Is this trend, seen over the past decade, a harbinger of the future for marine ecosystems?
  • Ocean–cloud–atmosphere–land interactions in the southeastern Pacific : the VOCALS Program 

    Mechoso, C. R.; Wood, R.; Weller, Robert A.; Bretherton, Christopher S.; Clarke, A. D.; Coe, H.; Fairall, Christopher W.; Farrar, J. Thomas; Feingold, G.; Garreaud, R.; Grados, Carmen; McWilliams, James C.; de Szoeke, Simon P.; Yuter, S. E.; Zuidema, Paquita (American Meteorological Society, 2014-03)
    The present paper describes the Variability of the American Monsoon Systems (VAMOS) Ocean–Cloud–Atmosphere–Land Study (VOCALS), an international research program focused on the improved understanding and modeling of the ...
  • Off-axis effects on the multipulse structure of sperm whale usual clicks with implications for sound production 

    Zimmer, Walter M. X.; Madsen, Peter T.; Teloni, Valeria; Johnson, Mark P.; Tyack, Peter L. (Acoustical Society of America, 2005-11)
    Sperm whales (Physeter macrocephalus) produce multipulsed clicks with their hypertrophied nasal complex. The currently accepted view of the sound generation process is based on the click structure measured directly in front ...
  • Offshore transport of dense water from the East Greenland Shelf 

    Harden, Benjamin E.; Pickart, Robert S.; Renfrew, Ian A. (American Meteorological Society, 2014-01)
    Data from a mooring deployed at the edge of the East Greenland shelf south of Denmark Strait from September 2007 to October 2008 are analyzed to investigate the processes by which dense water is transferred off the shelf. ...
  • Offshore transport of shelf waters through interaction of vortices with a shelfbreak current 

    Cenedese, Claudia; Todd, Robert E.; Gawarkiewicz, Glen G.; Owens, W. Brechner; Shcherbina, Andrey Y. (American Meteorological Society, 2013-05)
    Interactions between vortices and a shelfbreak current are investigated, with particular attention to the exchange of waters between the continental shelf and slope. The nonlinear, three-dimensional interaction between an ...
  • An old salt retires 

    Schmitt, Raymond W. (The Oceanography Society, 2015-03)
    In September and October 2012, R/V Knorr operated in the North Atlantic to deploy autonomous platforms that would collect measurements over the following year for the first phase of the Salinity Processes in the Upper-ocean ...
  • Oligotyping reveals community level habitat selection within the genus Vibrio 

    Schmidt, Victor T.; Reveillaud, Julie; Zettler, Erik R.; Mincer, Tracy J.; Murphy, Leslie G.; Amaral-Zettler, Linda A. (Frontiers Media, 2014-11-13)
    The genus Vibrio is a metabolically diverse group of facultative anaerobic bacteria, common in aquatic environments and marine hosts. The genus contains several species of importance to human health and aquaculture, including ...
  • Olivine friction at the base of oceanic seismogenic zones 

    Boettcher, Margaret S.; Hirth, Greg; Evans, Brian (American Geophysical Union, 2007-01-31)
    We investigate the strength and frictional behavior of olivine aggregates at temperatures and effective confining pressures similar to those at the base of the seismogenic zone on a typical ridge transform fault. Triaxial ...
  • On acoustic scattering by a shell-covered seafloor 

    Stanton, Timothy K. (Acoustical Society of America, 2000-08)
    Acoustic scattering by the seafloor is sometimes influenced, if not dominated, by the presence of discrete volumetric objects such as shells. A series of measurements of target strength of a type of benthic shelled animal ...
  • On dynamically consistent eddy fluxes 

    Berloff, Pavel S. (2004-11-04)
    The role of mesoscale oceanic eddies in driving the large-scale currents is studied in an eddy-resolving, double-gyre ocean model. The new diagnostic method is proposed, which is based on dynamical decomposition of the ...
  • On eddy viscosity, energy cascades, and the horizontal resolution of gridded satellite altimeter products 

    Arbic, Brian K.; Polzin, Kurt L.; Scott, Robert B.; Richman, James G.; Shriver, Jay F. (American Meteorological Society, 2013-02)
    Motivated by the recent interest in ocean energetics, the widespread use of horizontal eddy viscosity in models, and the promise of high horizontal resolution data from the planned wide-swath satellite altimeter, this paper ...
  • On estimating the number of species from the discovery record 

    Solow, Andrew R.; Smith, Woollcott K. (Royal Society, 2005-02-04)
    A common approach to estimating the number of species in a taxonomic or other group is to extrapolate the temporal pattern of historical species discoveries or descriptions. A formal statistical approach to this problem ...
  • On latency of multiple zonal jets in the oceans 

    Berloff, Pavel S.; Karabasov, S. A.; Farrar, J. Thomas; Kamenkovich, Igor V. (Cambridge University Press, 2011-09-27)
    Most of the nearly zonal, multiple, alternating jets observed in the oceans are latent, that is, their amplitudes are weak relative to the ambient mesoscale eddies. Yet, relatively strong jets are often observed in dynamical ...
