    • Design considerations for stretch conductors in oceanographic moorings 

      Paul, Walter (Woods Hole Oceanographic Institution, 1995-12)
      A copper conductor formed into a helical configuration like a telephone cord can stretch by extending its geometry without elongating the conductor itself. This report establishes the proper configuration of copper conductors ...
    • Design curves for oceanographic pressure-resistant housings 

      Sharp, Arnold G. (Woods Hole Oceanographic Institution, 1981-08)
      Curves have been prepared to serve as a guide in designing externally pressurized cylindrical and spherical housings and flat end closures. The plots show wall thickness-to-diameter ratio as a function of collapse depth ...
    • Design of a controllable pitch underwater thruster system 

      Keefe, Robert W. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1993-08)
      Control systems for underwater vehicles have reached the level of sophistication where they are limited by the dynamic performance of the thrust actuators. Standard fixed-pitch propellers have been shown to have very ...
    • Design of a stable floating platform for air-sea interaction measurements 

      Berteaux, Henri O.; Walden, Robert G. (Woods Hole Oceanographic Institution, 1978-12)
      The design of an oceanographic platform can be defined as the rational specification of the platform dimensions and geometry. This specification is usually the result of an iterative process which compares the ...
    • The design of a surface launch and recovery fender for DSRV "Alvin" 

      O'Sullivan, James Francis (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1973-09)
      Surface recovery of small submersibles could be made safer for personnel and hardware with the installation on the submersible of an inflatable, pneumatic bumper which acts also as main surface buoyancy. Tne use of such ...
    • The design of an instrument to measure vertically averaged oceanic currents using geomagnetic electric fields 

      Poranski, Peter Frank (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1972-08)
      A bottom mounted electromagnetic current meter measures the vertically-averaged conductivity-weighted velocity. This measurement complements free-fall relative velocity profiles and is valuable for transport determination ...
    • Design study for a moored surface-scanning sonar
