  • Watkins, William A. (Woods Hole Oceanographic Institution, 1968-03)
    The harmonic interval indicated during spectrographic analysis of a rapid train of pulses may be used to determine the pulse repetition-rate. If the pulse rate is regular, but too rapid to be separated, the repetition-rate ...
  • Jemsek, John P. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1988-05)
    Heat flow, tectonic subsidence and crustal thickness distributions in the Ligurian Basin are best explained by asymmetric lithospheric thinning mechanisms. Over 150 heat flow measurements are made on several transects ...
  • Lucazeau, Francis; Bonneville, Alain; Escartin, Javier; von Herzen, Richard P.; Gouze, Philippe; Carton, Helene; Cannat, Mathilde; Vidal, Valerie; Adam, Claudia (American Geophysical Union, 2006-07-27)
    We report 157 closely spaced heat flow measurements along the Lucky Strike segment in the Mid-Atlantic Ridge (MAR) for ages of the ocean floor between 0 and 11 Ma. On the eastern flank of a volcanic plateau delimiting ...
  • Williams, David Lee (Woods Hole Oceanographic Institution, 1974-07)
    Lithospheric cooling along the Galapagos Spreading Center at 86°W longitude, as determined by surface heat-flow measurements, appears dominated by hydrothermal circulation. This same phenomena apparently exists on the ...
  • Wang, Pei-Ling; Engelhart, Simon E.; Wang, Kelin; Hawkes, Andrea D.; Horton, Benjamin P.; Nelson, Alan R.; Witter, Robert C. (John Wiley & Sons, 2013-05-15)
    Past earthquake rupture models used to explain paleoseismic estimates of coastal subsidence during the great A.D. 1700 Cascadia earthquake have assumed a uniform slip distribution along the megathrust. Here we infer ...
  • Xu, Min; Canales, J. Pablo; Tucholke, Brian E.; DuBois, David L. (American Geophysical Union, 2009-10-10)
    The Kane oceanic core complex (OCC) is a large, corrugated megamullion that was formed by a long-lived detachment fault at the axis of the Mid-Atlantic Ridge adjacent to Kane Fracture Zone between 2.1 and 3.3 Ma. We use ...
  • Biddle, Jennifer F.; Lipp, Julius S.; Lever, Mark A.; Lloyd, Karen G.; Sorensen, Ketil B.; Anderson, Rika; Fredricks, Helen F.; Elvert, Marcus; Kelly, Timothy J.; Schrag, Daniel P.; Sogin, Mitchell L.; Brenchley, Jean E.; Teske, Andreas; House, Christopher H.; Hinrichs, Kai-Uwe (National Academy of Sciences, 2006-02-27)
    Studies of deeply buried, sedimentary microbial communities and associated biogeochemical processes during Ocean Drilling Program Leg 201 showed elevated prokaryotic cell numbers in sediment layers where methane is consumed ...
  • Ashton, Andrew D.; Murray, A. Brad (American Geophysical Union, 2006-12-15)
    Contrary to traditional findings, the deepwater angle of wave approach strongly affects plan view coastal evolution, giving rise to an antidiffusional “high wave angle” instability for sufficiently oblique deepwater waves ...
  • Ashton, Andrew D.; Murray, A. Brad (American Geophysical Union, 2006-12-15)
    Recent research has revealed that the plan view evolution of a coast due to gradients in alongshore sediment transport is highly dependant upon the angles at which waves approach the shore, giving rise to an instability ...
  • Roberts, Mark L.; Burton, Joshua R.; Elder, Kathryn L.; Longworth, Brett E.; McIntyre, Cameron P.; von Reden, Karl F.; Han, Baoxi; Rosenheim, Brad E.; Jenkins, William J.; Galutschek, Ernst; McNichol, Ann P. (Dept. of Geosciences, University of Arizona, 2010-08)
    A new and unique radiocarbon accelerator mass spectrometry (AMS) facility has been constructed at the Woods Hole Oceanographic Institution. The defining characteristic of the new system is its large-gap optical elements ...
  • McGuire, Jeffrey J.; Ben-Zion, Yehuda (Blackwell Publishing, 2005-09-02)
    Detailed imaging of fault-zone (FZ) material properties at seismogenic depths is a difficult seismological problem owing to the short length scales of the structural features. Seismic energy trapped within a low-velocity ...
  • Makou, Matthew C.; Thompson, Lonnie G.; Montlucon, Daniel B.; Eglinton, Timothy I. (American Geophysical Union, 2009-07-03)
    Semi-volatile organic compounds derived from burned and fresh vascular plant sources and preserved in high-altitude ice fields were detected and identified through use of recently developed analytical tools. Specifically, ...
  • Tucholke, Brian E. (Woods Hole Oceanographic Institution, 1974-01)
    The Greater Antilles Outer Ridge is an 1800 km long, submarine sedimentary ridge which lies below 5000 m in the southwestern North Atlantic Ocean. Seismic reflection profiles and core data indicate that the ridge is ...
  • Ponton, Camilo; Giosan, Liviu; Eglinton, Timothy I.; Fuller, Dorian Q.; Johnson, Joel E.; Kumar, Pushpendra; Collett, Timothy S. (American Geophysical Union, 2012-02-14)
    Spanning a latitudinal range typical for deserts, the Indian peninsula is fertile instead and sustains over a billion people through monsoonal rains. Despite the strong link between climate and society, our knowledge of ...
  • Hu, Dengke; Clift, Peter D.; Boning, Philipp; Hannigan, Robyn E.; Hillier, Stephen; Blusztajn, Jerzy S.; Wan, Shiming; Fuller, Dorian Q. (John Wiley & Sons, 2013-07-26)
    Sediments in the Pearl River delta have the potential to record the weathering response of this river basin to climate change since 9.5 ka, most notably weakening of the Asian monsoon since the Early Holocene (∼8 ka). Cores ...
  • Dziak, Robert P.; Bohnenstiehl, DelWayne R.; Smith, Deborah K. (The Oceanography Society, 2012-03)
    Mid-ocean ridge volcanism and extensional faulting are the fundamental processes that lead to the creation and rifting of oceanic crust, yet these events go largely undetected in the deep ocean. Currently, the only means ...
  • Aubrey, David G.; Oguz, T.; Demirev, E.; Ivanov, V.; McSherry, T. R.; Diaconu, V.; Nikolaenko, E. (Woods Hole Oceanographic Institution, 1992-02)
    An Intercalibration Workshop was held at the Woods Hole Oceanographic Institution (W.H.O.I.) from 1-10 December, 1991, for the CTD data acquired during HYDROBLACK '91. This intercalibration exercise was a prelude to an ...
  • Salles, Paulo (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2001-02)
    The importance of the persistence of multiple inlets in coastal systems is fundamental for issues such as water quality, navigability, and beach/barrier stability. In long embayments, having extended residence times, the ...
  • Geist, Eric L.; Lynett, Patrick J.; Chaytor, Jason D. (Elsevier B.V., 2008-10-18)
    Tsunami generation from the Currituck landslide offshore North Carolina and propagation of waves toward the U.S. coastline are modeled based on recent geotechnical analysis of slide movement. A long and intermediate wave ...
  • Friedrichs, Carl T. (Woods Hole Oceanographic Institution, 1993-02)
    In this thesis, mechanisms which control morphodynamics of shallow tidal embayments are investigated analytically. In the process of exploring these mechanisms (specifically asymmetries in bottom stress, τ), basis momentum ...
