    Experimental evaluation of CTD package hydrodynamic behavior and recommendations for improved lowering techniques
    (Woods Hole Oceanographic Institution, 1983-07) Berteaux, Henri O. ; Walden, Robert G. ; Clay, Peter R. ; McDevitt, R. E.
    This report is the last of a series of three reports on a comprehensive study of CTD instrument lowering mechanics. The first report, WHOI 79-81, "A Study of CTD Cables and Lowering Systems", examines the causes and modes of lowering cable failures, both mechanical and electrical, and makes recommendations to improve existing instrument packages and lowering procedures. The second report, WHOI 81-76, "Hydrodynamics of CTD Instrument Packages", is a theoretical study of instrument package stability when cable lowered or free falling. The model is used to predict the hydrodynamic response of CTD packages in their present or improved configuration. This report, WHOI 83-21, is more factual. It describes the tests performed on scale models and actual CTD packages to actually observe and/or measure their hydrodynamic behavior. Analytical results and experimental data obtained in this study are used to draw recommendations for CTD package improvement and future lowering procedures.

    Real-time environmental Arctic monitoring (R-TEAM) deployment cruise
    (Woods Hole Oceanographic Institution, 1988-12) Clay, Peter R. ; Briscoe, Melbourne G.
    The R-TEAM mooring was deployed on August 24, 1988 at the coordinates of 79°25'.92N and 06°47'.91 E. This technical report describes the mooring as set and the deployment procedures.

    A performance update of the InterOcean S4 electromagnetic current meter
    (Woods Hole Oceanographic Institution, 1986-10) Clay, Peter R. ; Longworth, Steven P.
    This report reviews the working principles of the InterOcean S4 electromagnetic current meter and outlines the practical difficulties and engineering solutions to convert these basic principles into a working instrument. Presented are the test procedures and results performed on three production units placing emphasis on the oceanographic users point of view. These tests, performed by the Ocean Structures and Moorings Laboratory, Ocean Engineering Department, Woods Hole Oceanographic Institution (WHOI), include laboratory, dockside, and both surface and subsurface mooring tests. S4s are compared to each other and to other types of current meters in various intercomparison tests. Results of. this evaluation program are next summarized. Also, suggestions for areas of improvement and further developments are made. Finally, recommendations for the acceptance, calibration, and burning in of new instruments conclude the report.
