  • Yubuki, Naoji; Edgcomb, Virginia P.; Bernhard, Joan M.; Leander, Brian S. (BioMed Central, 2009-01-27)
    The Euglenozoa is a large group of eukaryotic flagellates with diverse modes of nutrition. The group consists of three main subclades – euglenids, kinetoplastids and diplonemids – that have been confirmed with both molecular ...

    The Hawaiian Islands are the canonical example of an age-progressive island chain, formed by volcanism long thought to be fed from a hotspot source that is more or less fixed in the mantle. Geophysical data, however, have ...
  • Bach, Wolfgang; Paulick, Holger; Garrido, Carlos J.; Ildefonse, Benoit; Meurer, William P.; Humphris, Susan E. (American Geophysical Union, 2006-07-06)
    The results of detailed textural, mineral chemical, and petrophysical studies shed new light on the poorly constrained fluid-rock reaction pathways during retrograde serpentinization at mid-ocean ridges. Uniformly depleted ...

    Recent P wave velocity compilations of the oceanic crust indicate that the velocity of the uppermost layer 2A doubles or reaches ∼4.3 km/s found in mature crust in <10 Ma after crustal formation. This velocity change is ...

    We use multichannel seismic reflection data to image the upper crustal structure of 0-620 ka crust along the southern Juan de Fuca Ridge (JdFR). The study area comprises two segments spreading at intermediate rate with ...

    This paper reports on a magnetotelluric (MT) survey across the central Mariana subduction system, providing a comprehensive electrical resistivity image of the upper mantle to address issues of mantle dynamics in the mantle ...
  • Hoffmann, Sharon S. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2009-02)
    The radionuclides 231Pa and 230Th, produced in the water column and removed from the ocean by particle scavenging and burial in sediments, offer a means for paleoceanographers to examine past dynamics of both water column ...
  • Stephen, Ralph A. (Woods Hole Oceanographic Institution, 1992-05)
    FINDIF solves the elastic wave equation for a line source in two dimensions by the finite difference method (Virieux,1986; Stephen,1988b). The solution is carried out in the time domain for either pulse or CW sources. ...
  • Bolmer, S. Thompson; Stephen, Ralph A. (Woods Hole Oceanographic Institution, 2006-02)
    PLOT_FINDIF is a MATLAB script which is used to plot output from the Woods Hole Oceanographic Institution (WHOI) Time Domain Finite Difference (TDFD) program called "Geoacoustic_TDFD" Both Geoacoustic_TDFD and PLOT_FINDIF ...
  • Hunt, Mary M.; Stephen, Ralph A. (Woods Hole Oceanographic Institution, 1986-11)
    Over the past eight years, a software package has been developed to solve the elastic wave equation by the method of finite differences (Hunt et al., 1983; Stephen, 1983; Stephen, 1984a; Stephen, 1984b; Nicoletis, 1981). ...
  • Evans, Rob L. (Society of Exploration Geophysicists, 2007-03-01)
    Many important processes occur within the shallow section of the seafloor on the continental shelf and slope, yet conventional geophysical constraints on the physical properties within this critical boundary layer are ...
  • Freed, Andrew M.; Hirth, Greg; Behn, Mark D. (American Geophysical Union, 2012-01-31)
    To interpret short-term postseismic surface displacements in the context of key ambient conditions (e.g., temperature, pressure, background strain rate, water content, creep mechanism), we combined steady state and transient ...
  • Koppers, Anthony A. P.; Staudigel, Hubert; Hart, Stanley R.; Young, Craig M.; Konter, Jasper G. (Oceanography Society, 2010-03)
    Vailulu’u seamount is an active underwater volcano that marks the end of the Samoan hotspot trail.
  • Staudigel, Hubert; Hart, Stanley R.; Pile, Adele; Bailey, Bradley E.; Baker, Edward T.; Brooke, Sandra; Connelly, Douglas P.; Haucke, Lisa; German, Christopher R.; Hudson, Ian; Jones, Daniel; Koppers, Anthony A. P.; Konter, Jasper G.; Lee, Ray; Pietsch, Theodore W.; Tebo, Bradley M.; Templeton, Alexis S.; Zierenberg, Robert; Young, Craig M. (National Academy of Sciences, 2006-04-13)
    Submersible exploration of the Samoan hotspot revealed a new, 300-m-tall, volcanic cone, named Nafanua, in the summit crater of Vailulu'u seamount. Nafanua grew from the 1,000-m-deep crater floor in <4 years and could reach ...
  • Carbotte, Suzanne M.; Nedimovic, Mladen R.; Canales, J. Pablo; Kent, Graham M.; Harding, Alistair J.; Marjanovic, Milena (American Geophysical Union, 2008-08-02)
    Multichannel seismic and bathymetric data from the Juan de Fuca Ridge (JDFR) provide constraints on axial and ridge flank structure for the past 4–8 Ma within three spreading corridors crossing Cleft, Northern Symmetric, ...

    The rifting of continental lithosphere is a fundamental solid-earth process that leads to the formation of rifted continental margins and ocean basins. Understanding of this process comes from observations of the geometry ...

    Stable isotope and ice-rafted debris records from three core sites in the mid-latitude North Atlantic (IODP Site U1313, MD01-2446, MD03-2699) are combined with records of ODP Sites 1056/1058 and 980 to reconstruct hydrographic ...
  • Kong, Laura S. L. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1990-06)
    The variation in the depth and width of the median valley along the Mid-Atlantic Ridge (MAR) suggests that the formation of ocean crust at slow spreading centers is not a simple two-dimensional process in which crustal ...
