  • Green, Kenneth Edward (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1980-02)
    The measurements of the heat flow field of the Galapagos Spreading Center in an area of about 570 km2 reveal the planform of the conductive flux and permit the first truly areal estimate of the near-axis heat flux for ...
  • Chechelnitsky, Michael Y. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1996-05)
    TOPEX/POSEIDON altimetry data are employed in the analysis of the global ocean response to atmospheric forcing. We use two different approaches to test the hypothesis that the global sea surface height variability can ...
  • Oschmann, Lynn A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1991-08)
    Sr, Nd and Pb isotopic analyses of 477 samples representing 30 islands or island groups, 3 seamounts or seamount chains, 2 oceanic ridges and 1 oceanic plateau [for a total of 36 geographic features] are compiled to form ...
  • Folinsbee, Robert Allin (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1972-01)
    Free-air and simple Bouguer anomaly maps of the Venezuelan continental margin (from 60°W to 72°W and from 7°N to 13°N) are presented. The major features of the free-air map are: the large lows associated with the deep ...
  • White, Meredith M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2013-02)
    Coastal and estuarine environments experience large variability and rapid shifts in pCO2 levels. Elevated pCO2, or ocean acidification, often negatively affects early life stages of calcifying m ...
  • Lund, David C. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2006-02)
    Benthic and planktonic foraminiferal δ18O (δ18Oc) from a suite of well-dated, high-resolution cores spanning the depth and width of the Straits of Florida reveal significant changes in Gulf Stream cross-current density ...
  • Gulmann, Lara K. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2004-09)
    Digestive associations between marine invertebrates and resident (attached) microbial communities may playa critical role in host physiology and involve previously unidentified microbial species. The overarching goal of ...
  • Pangallo, Kristin C. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2009-09)
    Halogenated 1’-methyl-1,2’-bipyrroles (MBPs) are a distinctive class of marine organic compounds. They are naturally produced, they have a unique carbon structure, they are highly halogenated, and they bioaccumulate in ...
  • 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 ...
  • 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 ...
  • Graham, David W. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1987-09)
    The isotopic evolution of helium and lead in the Earth is coupled by virtue of their common radioactive parents uranium and thorium. The isotopic signatures in oceanic volcanic rocks provide constraints on the temporal ...
  • Kurz, Mark D. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1982-06)
    The concentrations and isotopic compositions of helium have been measured in a number of mantle derived oceanic basalts. The goal of this research is to use the helium isotopic systematics to constrain the nature and ...
  • Aluwihare, Lihini I. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1999-04)
    The goal of this thesis was to use high resolution analytical techniques coupled with molecular level analyses to chemically characterize high molecular weight (> 1 k Da (HMW)) dissolved organic matter (DOM) isolated ...
  • Panteleyev, George P. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1995-05)
    Much of the nuclear activity of the former Soviet Union took place within or adjacent to the confines of the Ob River drainage basin. These activities include weapons production and reprocessing at Chelyabinsk-65 (also ...
  • 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 ...
  • Hall, Melinda M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1985-02)
    From October, 1982 to October, 1983 a current meter mooring reaching from the bottom into the thermocline was deployed for the first time in the Gulf Stream at 68°W. The temperatures, pressures, and velocities at the ...
  • Traykovski, Peter A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1994-01)
    In 1991 the Heard Island Feasibility Test demonstrated that it is possible to transmit coded acoustic signals nearly half way around the world. One of the key issues in the feasibility test was to determine the spatial ...
  • Galvin, Lawrence F. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1991-08)
    Undersea technology is on the verge of equipping remotely operated vehicle (ROV) pilots with a three-dimensional (3-D), real-time display incorporating data from a wide variety of sensors including sonar (sound navigation ...
  • Vaughn, Gregory M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1988-08)
    This paper explores the use of 'hybrid' state estimators to increase the accuracy and flexibility of acoustic position measurement systems used in the control of underwater vehicles. Two different approaches to extend ...
  • Ralph, Elise A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1994-09)
    The thesis addresses the applicability of traditional hydraulic theory to an unstable, mid-latitude jet where the only wave present is the Rossby wave modified by shear. While others (Armi 1989, Pratt 1989, Haynes et ...
