  • Garland, Elizabeth D.; Mullineaux, Lauren S. (Woods Hole Oceanographic Institution, 1992-06)
    Patterns and rates of particle contact onto flat plates in steady unidirectional flows were investigated in a laboratory flume. Plates with three leading edge configurations (faired, bluff and split) were used to generate ...
  • Buesseler, Ken O.; Andrews, J. E.; Pike, Steven M.; Charette, Matthew A.; Goldson, Laura E.; Brzezinski, Mark A.; Lance, V. P. (2004-07-26)
    We studied the effect of iron addition on particle export in the Southern Ocean by measuring changes in the distribution of thorium-234 during a 4 week Fe enrichment experiment conducted in the high-silicate high-nitrate ...
  • Ducklow, Hugh W.; Erickson, Matthew; Kelly, Joann; Montes-Hugo, Martin; Ribic, Christine A.; Smith, Raymond C.; Stammerjohn, Sharon E.; Karl, David M. (2008-03)
    We report on results of a long-term (1993-2007) time series sediment trap moored at 170 m to the west of the Antarctic Peninsula in the mid-continental shelf region (350 m depth; 64º30’ S, 66º00’ W). This is a region ...
  • Buesseler, Ken O.; Lamborg, Carl H.; Cai, Pinghe; Escoube, Raphaelle; Johnson, Rodney J.; Pike, Steven M.; Masque, Pere; McGillicuddy, Dennis J.; Verdeny, E. (2007-09-25)
    We examined the impact of a cyclonic eddy and mode-water eddy on particle flux in the Sargasso Sea. The primary method used to quantify flux was based upon measurements of the natural radionuclide, 234Th, and these flux ...
  • Hay, Bernward J. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1987-09)
    The particle flux in the present and over the last 5,000 years was investigated in the Black Sea in a comparative study with samples from time-series sediment traps and laminated core sediments. The sediment trap samples ...
  • Marchal, Olivier (2006-04-25)
    The 'Sandström theorem' as interpreted by Jeffreys (1925) is that in a flow maintained by a temperature difference, the pathline from the cold region to the warm region must lie below the return path. A formal demonstration ...
  • Wiebe, Peter H.; Boyd, Steven H.; Winget, Clifford L. (Woods Hole Oceanographic Institution, 1976-09)
    A sedimentation trap for use just above the deep-sea floor was free-fallen to a depth of 2050 m in the Tongue of the Ocean canyon on January 3, 1974. On March 6, it was successfully recovered with the assistance of ...
  • Twichell, David C.; Cross, VeeAnn A.; Peterson, Curt D. (Elsevier B.V., 2010-02-11)
    Sediment derived from the Columbia River has been deposited on the continental shelf, along the barriers and beaches, and in the bays of the Oregon and Washington coast during the Holocene. The barrier and beach deposits ...
  • Gabitov, R. I.; Watson, E. B. (American Geophysical Union, 2006-11-07)
    The Sr/Ca ratio of biogenic carbonate is widely used as a proxy for paleotemperature. This application is supported by empirical calibrations of Sr/Ca as a function of temperature, but it is also known that Sr uptake in ...
  • Jenkins, William J.; Elder, Kathryn L.; McNichol, Ann P.; von Reden, Karl F. (Dept. of Geosciences, University of Arizona, 2010-08)
    We report and compare radiocarbon observations made on 2 meridional oceanographic sections along 150°W in the South Pacific in 1991 and 2005. The distributions reflect the progressive penetration of nuclear weapons-produced ...
  • Zimmer, Walter M. X.; Harwood, John; Tyack, Peter L.; Johnson, Mark P.; Madsen, Peter T. (Acoustical Society of America, 2008-11)
    Beaked whales can remain submerged for an hour or more and are difficult to sight when they come to the surface to breathe. Passive acoustic detection (PAD) not only complements traditional visual-based methods for detecting ...
  • Bowen, Martin F. (Woods Hole Oceanographic Institution, 1998-06-12)
    Under subcontract to the Massachusetts Institute of Techology's (MIT) Sea Grant Autonomous Ocean Sampling Network (AOSN) program, the Woods Hole Oceanographic Institution's Deep Submergence Laboratory (WHOI-DSL) produced ...
  • Gemmell, Brad J.; Costello, John H.; Colin, Sean P.; Stewart, Colin J.; Dabiri, John O.; Tafti, Danesh; Priya, Shashank (2013-08)
    Gelatinous zooplankton populations are well known for their ability to take over perturbed ecosystems. The ability of these animals to outcompete and functionally replace fish that exhibit an effective visual predatory ...
  • Wojcik, Dennis M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1993-09)
    This thesis examines the use of a single, omnidirectional hydrophone as a receiving sensor to passively localize an acoustic beacon. The localization problem is presented as a constrained, nonlinear parameter estimation ...
  • Song, Aijun; Badiey, Mohsen; Newhall, Arthur E.; Lynch, James F.; DeFerrari, Harry A.; Katsnelson, Boris G. (IEEE, 2010-11-30)
    During a 12-h period in the 2006 Shallow Water Experiment (SW06), binary phase shift keying (BPSK) signals at the carrier frequencies of 813 and 1627 Hz were propagated over a 19.8-km source–receiver range when a packet ...
  • Knapp, Alan K.; Smith, Melinda D.; Hobbie, Sarah E.; Collins, Scott L.; Fahey, Timothy J.; Hansen, Gretchen J. A.; Landis, Douglas A.; La Pierre, Kimberly J.; Melillo, Jerry M.; Seastedt, Timothy R.; Shaver, Gaius R.; Webster, Jackson R. (American Institute of Biological Sciences, 2012-04)
    The US National Science Foundation—funded Long Term Ecological Research (LTER) Network supports a large (around 240) and diverse portfolio of long-term ecological experiments. Collectively, these long-term experiments have ...
  • Kanaan, Nicholas M.; Morfini, Gerardo A.; LaPointe, Nichole E.; Pigino, Gustavo F.; Patterson, Kristina R.; Song, Yuyu; Andreadis, Athena; Fu, Yifan; Brady, Scott T.; Binder, Lester I. (Society for Neuroscience, 2011-07-06)
    Aggregated filamentous forms of hyperphosphorylated tau (a microtubule-associated protein) represent pathological hallmarks of Alzheimer's disease (AD) and other tauopathies. While axonal transport dysfunction is thought ...
  • Morfini, Gerardo A.; You, Yi-Mei; Pollema, Sarah L.; Kaminska, Agnieszka; Liu, Katherine; Yoshioka, Katsuji; Bjorkblom, Benny; Coffey, Eleanor T.; Bagnato, Carolina; Han, David; Huang, Chun-Fang; Banker, Gary; Pigino, Gustavo F.; Brady, Scott T. (2009-04-28)
    Selected vulnerability of neurons in Huntington’s disease (HD) suggests alterations in a cellular process particularly critical for neuronal function. Supporting this idea, pathogenic Htt (polyQ-Htt) inhibits fast axonal ...

    A “Perspective” for Science, introducing the paper "Biomarker Evidence for a Major Preservation Pathway of Sedimentary Organic Carbon," by Y. Hebting, P. Schaeffer, A. Behrens, P. Adam, G. Schmitt, P. Schneckenburger, ...
