    Abstract
    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.
