  • Development and application of a field instrumentation system for the investigation of surf zone hydrodynamics 

    Greer, Matthew Noble (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1979-02)
    The development and application of an autonomous field instrumentation system consisting of four current meters and four wave gauges, along with a field monitor and digital recorder, is documented. The flow sensors are ...
  • Electromagnetic flow sensors 

    Lawson, Kenneth; Kanwisher, John W. (Woods Hole Oceanographic Institution, 1974-03)
    Flow sensors based on the principle of electromagnetic induction were investigated as alternatives to commonly used mechanical devices utilizing rotors and propellers. Prototype sensors were constructed showing ...
  • An electromagnetic method for measuring the velocities of ocean currents from a ship under way 

    Von Arx, William S. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1950-03)
    During the past four years a deliberate effort has been made at the Woods Hole Oceanographic Institution to devise methods of kinematic observation generally suited to the needs of oceanographers. One result of this work, ...
  • Summary of current meter operations in 1968 

    McCullough, James R.; Tupper, George H. (Woods Hole Oceanographic Institution, 1969-03)
    This report describes work done with Geodyne current meters and wind recorders during 1968. Techniques for testing instruments prior to use at sea, instrument performance at sea and instrument changes evolved during the ...
