  • DeRuiter, Stacy L.; Tyack, Peter L.; Lin, Ying-Tsong; Newhall, Arthur E.; Lynch, James F.; Miller, Patrick J. O. (Acoustical Society of America, 2006-12)
    In 2002 and 2003, tagged sperm whales (Physeter macrocephalus) were experimentally exposed to airgun pulses in the Gulf of Mexico, with the tags providing acoustic recordings at measured ranges and depths. Ray trace and ...
  • Jakuba, Michael V. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2003-02)
    The Sentry AUV represents a radical departure from conventional AUV design, particularly with respect to actuation. The vehicle's combined foil/thruster actuators have the potential to produce a vehicle both maneuverable ...
  • Severson, Jared (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2009-02)
    Marine mammal whistle calls present an attractive medium for covert underwater communications. High quality models of the whistle calls are needed in order to synthesize natural-sounding whistles with embedded information. ...
  • Bhushan, Vikas (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1998-09)
    A detailed examination of the development of a deep convection event observed in the Greenland Sea in 1988-89 is carried out through a combination of modeling, scale estimates, and data analysis. We develop a prognostic ...
  • Rastetter, Edward B. (Ecological Society of America, 2011-02)
    Organisms require about 30 essential elements to sustain life. The cycles of these elements are coupled to one another through the specific physiological requirements of the organisms. Here, I contrast several approaches ...
  • Udovydchenkov, Ilya A.; Duda, Timothy F.; Doney, Scott C.; Lima, Ivan D. (Acoustical Society of America, 2010-08-19)
    Possible future changes of ambient shipping noise at 0.1–1 kHz in the North Pacific caused by changing seawater chemistry conditions are analyzed with a simplified propagation model. Probable decreases of pH would cause ...
  • Fennel, Katja; Brady, Damian; DiToro, Dominic; Fulweiler, Robinson W.; Gardner, Wayne S.; Giblin, Anne E.; McCarthy, Mark J.; Rao, Alexandra; Seitzinger, Sybil P.; Thouvenot-Korppoo, Marie; Tobias, Craig R. (2008-10-10)
    Sediment denitrification is a major pathway of fixed nitrogen loss from aquatic systems. Due to technical difficulties in measuring this process and its spatial and temporal variability, estimates of local, regional and ...
  • Li, Dan (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1997-09)
    Acoustic propagation in the ocean inevitably encounters inhomogeneities of various types, which give rise to scattering. Acoustic scattering from rough water /bottom interfaces comprised of exposed rocks and sea mountains ...
  • Stephen, Ralph A.; Swift, Stephen A. (Acoustical Society of America, 1994-08)
    A numerical scattering chamber (NSC) has been developed to compute backscatter functions for geologically realistic seafloor models. In the NSC, solutions are computed to the elastic (or anelastic) wave equation by the ...
  • Stephen, Ralph A. (Acoustical Society of America, 1996-10)
    A numerical scattering chamber based on the time-domain finite-difference solution of the two-way elastic wave equation is applied to a sea surface scattering problem, and excellent agreement is obtained in amplitude and ...
  • Duda, Timothy F.; Preisig, James C. (IEEE, 1999-01)
    Propagation of 400-Hz sound through continental-shelf internal solitary wave packets is shown by numerical simulation to be strongly influenced by coupling of normal modes. Coupling in a packet is controlled by the mode ...
  • Jin, X.; Najjar, Raymond G.; Louanchi, F.; Doney, Scott C. (American Geophysical Union, 2007-05-09)
    An ecosystem model embedded in a global ocean general circulation model is used to quantify roles of biological and physical processes on seasonal oxygen variations. We find that the thermally induced seasonal net outgassing ...
  • Malinverno, Alberto; Pohlman, John W. (American Geophysical Union, 2011-07-12)
    The sulfate-methane transition (SMT), a biogeochemical zone where sulfate and methane are metabolized, is commonly observed at shallow depths (1–30 mbsf) in methane-bearing marine sediments. Two processes consume sulfate ...
  • Feddersen, Falk; Clark, David B.; Guza, R. T. (American Geophysical Union, 2011-11-18)
    A model that accurately simulates surf zone waves, mean currents, and low-frequency eddies is required to diagnose the mechanisms of surf zone tracer transport and dispersion. In this paper, a wave-resolving time-dependent ...
  • Clark, David B.; Feddersen, Falk; Guza, R. T. (American Geophysical Union, 2011-11-18)
    Five surf zone dye tracer releases from the HB06 experiment are simulated with a tracer advection diffusion model coupled to a Boussinesq surf zone model (funwaveC). Model tracer is transported and stirred by currents and ...
  • Parekh, Payal; Follows, Michael J.; Boyle, Edward A. (American Geophysical Union, 2004-01-07)
    We describe a model of the ocean transport and biogeochemical cycling of iron and the subsequent control on export production and macronutrient distributions. Ocean transport of phosphorus and iron are represented by a ...
  • Zhang, Jinlun; Spitz, Yvette H.; Steele, Michael; Ashjian, Carin J.; Campbell, Robert G.; Berline, Leo; Matrai, Patricia (American Geophysical Union, 2010-10-08)
    We have developed a coupled 3-D pan-Arctic biology/sea ice/ocean model to investigate the impact of declining Arctic sea ice on the marine planktonic ecosystem over 1988–2007. The biophysical model results agree with ...
  • Petrik, Colleen M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2011-02)
    The ultimate goal of early life studies of fish over the past century has been to better understand recruitment variability. Recruitment is the single most important natural event controlling year-class strength and ...
  • Peng, Benrong; Lin, Chenchen; Jin, Di; Rao, Huanhuan; Jiang, Yuwu; Liuc, Yan (2013-03)
    This paper presents an analytical framework to estimate the Total Allowable Area for Coastal Reclamation (TAACR) to provide scientific support for the implementation of a coastal reclamation restriction mechanism. The logic ...
  • Manizza, Manfredi; Follows, Michael J.; Dutkiewicz, Stephanie; McClelland, James W.; Menemenlis, Dimitris; Hill, C. N.; Townsend-Small, Amy; Peterson, Bruce J. (American Geophysical Union, 2009-10-07)
    The spatial distribution and fate of riverine dissolved organic carbon (DOC) in the Arctic may be significant for the regional carbon cycle but are difficult to fully characterize using the sparse observations alone. ...
