    • Technical summary of USGS OBS operation R/V JOIDES Resoultion, ODP leg 179 

      Busby, Robert W.; Hoskins, Hartley (Woods Hole Oceanographic Institution, 2001)
      The experiment was to determine if a technique known as "Seismics While Drilling" was a viable means of gathering seismic images of near hole structure without consuming any rig time. The idea is to use a correlation ...
    • Tests of propellers for Alvin side propulsion units 

      Sharp, Arnold G.; Sullivan, James R. (Woods Hole Oceanographic Institution, 1967-07)
      Full scale dynamometer tests were run on a series of unshrouded propellers in the range of propeller diameters considered practical for use on the side propulsion units of the research submarine ALVIN. Measurements taken ...
    • Tests of the broadband borehole seismic system (B³S²) at Scripps IGPP and the Pinon Flat Observatory : October 1994 to June 1995 

      Stephen, Ralph A.; Orcutt, John; Peal, Kenneth R.; Vernon, Frank L.; Austin, Gary; Bolmer, S. Thompson; Gould, Matthew R.; Koelsch, Donald E.; Hollinshead, C. B.; Offield, Glen; Willoughby, David F. (Woods Hole Oceanographic Institution, 1997-08)
      The broadband borehole seismic system (B3S2) is being developed as one component of the Ocean Seismic Network (OSN) Pilot Experiment which will be carried out at the OSN-1 Site off Hawaii in Winter 1998. The other major ...
    • Transcription of 9-track tapes to CD-ROM 

      Bolmer, S. Thompson; DuBois, David L.; Hoskins, Hartley; Sass, Warren J. (Woods Hole Oceanographic Institution, 1999-12)
      The WHO! Marine Seismic community had about two thousand 9-track magnetic tapes in storage. The data stored were from marine experiments dating from the 1970's to 1990 and from computer models. The experiments included ...
    • Twenty-four (24) man-hour test of Alvin's environmental system 

      Learnard, H. H.; Marquet, William M.; McCamis, Marvin J. (Woods Hole Oceanographic Institution, 1964-11)
      ALVIN's specifications call for a 48 man-hour environmental system capability. To check this, a 24 man-hour test was run as follows: Two successive test periods of six (6) hours each with a two (2) man crew inside the ...
    • User's guide for FINDIF at SACLANTCEN 

      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. ...
    • A user’s manual for finite difference synthetic seismogram codes on the CYBER 205 and CRAY XMP-12 

      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). ...
