  • Blair, Ballard J. S. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2011-09)
    Underwater wireless communication is quickly becoming a necessity for applications in ocean science, defense, and homeland security. Acoustics remains the only practical means of accomplishing long-range communication ...
  • Duda, Timothy F. (IEEE, 1993-04)
    A group of amplitude and frequency modulated signals which generate narrow synthesized pulses are described. The pulse-compression properties of these signals should approach those of maximal (M) sequence phase-modulated ...
  • Headrick, Robert H. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1997-06)
    As part of the Shallow Water Acoustics in a Random Medium (SWARM) experiment [1], a sixteen element WHOI vertical line array (WVLA) was moored in 70 meters of water off the New Jersey coast. This array was sampled at ...
  • Ohta, Kazuhiko (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1993-09)
    In a shallow water ocean environment, the range-dependent variation of the geoacoustic properties of the seabed is one of the crucial factors affecting sound propagation. Since the local modes of propagation depend on ...
  • Dudko, Yuriy V. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1999-02)
    In this thesis the analysis of natural ice events is carried out based on direct measurements of ice-borne seismo-acoustic waves generated by ice fracturing processes. A major reason for studying this phenomenon is that ...
  • Lin, Ying-Tsong; Lynch, James F. (Acoustical Society of America, 2011-12-13)
    The horizontal ducting of sound by an oceanic temperature front over a sloping bottom is studied with an idealized wedge model consisting of a lateral interface across the slope. The water outside the frontal interface has ...
  • Aretxabaleta, Alfredo L.; Smith, Keston W. (2011-01-07)
    An approach to analyze regime change in spatial time series data sets is followed and extended to jointly analyze a dynamical model depicting regime shift and observational data informing the same process. We analyze ...
  • Leong, Doris; Ross, Tetjana; Lavery, Andone C. (Acoustical Society of America, 2012-08)
    High-frequency broadband (120–600 kHz) acoustic backscattering measurements have been made in the vicinity of energetic internal waves. The transducers on the backscattering system could be adjusted so as to insonify the ...
  • Maksym, Ted; Stammerjohn, Sharon E.; Ackley, Stephen; Massom, Rob (The Oceanography Society, 2012-09)
    As the world's ice diminishes in the face of climate change—from the dramatic decline in Arctic sea ice, to thinning at the margins of both the Greenland and Antarctic ice sheets, to retreating mountain glaciers the world ...
  • Byman, Michael W. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1989-08)
    When ocean waves in deep water interact with a current, the direction of propagation and characteristics of the waves such as height and length are affected. Swell in the open ocean can undergo significant refraction as ...
  • Chu, Dezhang; Stanton, Timothy K. (Acoustical Society of America, 1998-07)
    Distinct frequency dependencies of the acoustic backscattering by zooplankton of different anatomical groups have been observed in our previous studies [Chu et al., ICES J. Mar. Sci. 49, 97–106 (1992); Stanton et al., ICES ...
  • Ludvigsen, Martin; Sortland, Bjorn; Johnsen, Geir; Singh, Hanumant (Oceanography Society, 2007-12)
    In deep water, below the photic zone, still and video imaging of the seabed requires artificial lighting. Light absorption and backscatter caused by typical seawater components, such as dissolved organic matter, plankton, ...
  • Nadakuditi, Rajesh Rao (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2007-02)
    The first part of the dissertation investigates the application of the theory of large random matrices to high-dimensional inference problems when the samples are drawn from a multivariate normal distribution. A longstanding ...
  • Peal, Kenneth R. (Woods Hole Oceanographic Institution, 1990-11)
    A series of instrumented Arctic buoys has been developed which is designed to be deployed in pack ice to measure and record data from meteorological and ocean sensors as well as from an accelerometer package inside the ...
  • Nash, Jonathan D.; Shroyer, Emily L.; Kelly, Samuel M.; Inall, Mark E.; Duda, Timothy F.; Levine, Murray D.; Jones, Nicole L.; Musgrave, Ruth C. (The Oceanography Society, 2012-06)
    Surface tides are the heartbeat of the ocean. Because they are controlled by Earth's motion relative to other astronomical objects in our solar system, surface tides act like clockwork and generate highly deterministic ebb ...
  • Jones, Alan G.; Evans, Rob L.; Muller, Mark R.; Hamilton, Mark P.; Miensopust, Marion P.; Garcia, Xavier; Cole, Patrick; Ngwisanyi, Tiyapo; Hutchins, David; Fourie, C. J. S.; Jelsma, Hielke; Aravanis, Theo; Pettit, Wayne; Webb, Susan J.; Webb, Jan; Collins, Louise; Hogg, Colin; Horan, Clare; Spratt, Jessica; Wallace, Gerry; Chave, Alan D.; Cole, Janine; Stettler, Raimund; Tshoso, G.; Mountford, Andy; Cunion, Ed; Khoza, T. David; Share, Pieter-Ewald; SAMTEX Team (2009-06-05)
    Southern Africa, particularly the Kaapvaal Craton, is one of the world’s best natural laboratories for studying the lithospheric mantle given the wealth of xenolith and seismic data that exist for it. The Southern African ...
  • Woods Hole Oceanographic Institution (Woods Hole Oceanographic Institution, 1986-06)
    The purpose of the contract was to develop and place into operational status a new, combined research/inspection unmanned vehicle system called ARGO/JASON. ARGO is a high altitude search and survey vehicle for use in deep ...
  • von der Heydt, Keith; Kemp, John N.; Lynch, James F.; Miller, J.; Chiu, Ching-Sang (Woods Hole Oceanographic Institution, 1992-12)
    This report describes the application of a new technique of digital radio telemetry, based on a recently available wireless Local Area Network Ethernet adapter, to the need for realtime transmission of data from a vertical ...
  • Bondaryk, Joseph E. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1994-03)
    This thesis investigates array processing and forward modeling methods for the analysis of experimental, structural acoustic data to understand wave propagation on fluid-loaded, elastic, cylindrical shells in the ...
  • Hooker, Sascha K.; Miller, Patrick J. O.; Johnson, Mark P.; Cox, Oliver P.; Boyd, Ian L. (Royal Society, 2005-02-22)
    Novel observations collected from video, acoustic and conductivity sensors showed that Antarctic fur seals consistently exhale during the last 50–85% of ascent from all dives (10–160 m, n > 8000 dives from 50 seals). The ...
