    Woods Hole Oceanographic Institution
    Details
    Publication Date: 2022-11-18
    Description: In the fall of 1967 an extended program of tests was begun to evaluate several types of acoustic anchor release devices available on the market. This program was.prompted by a.need to isolate and correct problems which came to light after, several years of use of the O.R.E. system. Two other systems, one made by Raytheon and the other by American Machine and Foundry Co., were tested. This report deals with previous use of O.R.E.'s system by the W.H.O.I. Buoy Project and the testing program in 1968 and with the Raytheon and A.M.F. test series. Detailed description of these systems and their operation will not be undertaken in this report. Reference is made to data published by the respective manufacturers.

    Woods Hole Oceanographic Institution
    Details
    Publication Date: 2022-05-26
    Description: A moored two-dimensional array with instrumentation distributed both horizontally and vertically was deployed for 27 days in August 1998 at an 85 meter deep site in Massachusetts Bay near Stellwagon basin. The horizontal mooring consisted of a 160- meter long horizontal element positioned at a depth of 20 meters between two subsurface moorings. Suspended below the horizontal member were five 25-meter long vertical strings. The vertical strings had a horizontal separation of 30 meters and each had instruments at depths of 20, 25, 30, 35, 40 and 45 meters. Instrumentation deployed on the two-dimensional array included acoustic current meters, temperature sensors, conductivity measuring instruments, pressure sensors and motion monitoring packages. This report includes a detailed description of the two-dimensional array, the anchoring system and the instrumentation that were deployed. Also included is a description of the deployment and recovery techniques that were employed as well as an assessment of the performance of the array.

    Hose elements for buoy moorings : design, fabrication and mechanical properties (2006)
    Woods Hole Oceanographic Institution
    Details
    Publication Date: 2022-05-26
    Description: This report describes the design of tire cord reinforced rubber hoses, which have found an application as mooring hoses for oceanographic and offshore aquaculture buoy systems. These hoses stand out due to their ruggedness and ability to significantly stretch under load. The ruggedness is achieved through a steam curing = vulcanization process of the completed hose, generating a similar toughness of the hoses like automobile tires. Elastic stretch ranges can be designed from 30 to 130 percent through variation of the arrangement of the load carrying tire cord layers in the hose body. The hoses can also be furnished with electrical conductors and possibly optical light-guides as part of the hose wall. This technical report describes the design, fabrication, and mechanical properties of the mooring hoses to allow engineers to custom develop hoses with tailored mechanical properties.

    Deep sea moorings fishbite handbook (2007)
    Woods Hole Oceanographic Institution
    Details
    Publication Date: 2022-05-26
    Description: The purpose of this handbook is to bring awareness and a degree of expertise to the very real problem of fish attacks on mooring lines and cables deployed in the open seas. Over the years the authors have carefully examined a large sample of damaged, sometimes entirely severed ropes retrieved from the sea. Often direct evidence and/or biological observations showed that the ropes were the victims of fish attacks. In many cases however the cause of rope failure remained difficult to ascertain. Techniques and rationales therefore had to be devised to elucidate the more thorny cases. Understanding a problem, the saying goes, is half of the solution. The other half, as far as this handbook is concerned, is of course to make known the ways which, at the moment, could help prevent fishbite attacks or at least abate its effects. Thus the handbook will follow a natural progression. A short introduction retraces the early suspicions which soon translated into confirmed fish attacks. The next two chapters cover the recognition and the extent of the fishbite problem in great depth. Chapter 2 presents in meticulous details the techniques which can be used to determine how a rope was damaged while in service, either by fishbite or any other plausible cause. The analysis of a data base which spans over twenty years and encompasses close to a thousand moorings is presented in Chapter 3: Dimensions of the fishbite problem. This chapter provides valuable information for use in estimating fishbite hazard. Who are the culprits and why they do it is reviewed in Chapter 4: Biting organisms and predisposing factors. This chapter identifies the marine organisms which have significant biting capabilities and outlines some of the environmental factors and processes which incite and result in fishbite damage. The last chapter: Prevention and control of fishbite damage, reviews the preventive methods used to reduce the incidence or the severity of fish attacks and the curative methods - including up to date techniques for jacketing metallic and non-metallic ropes and cables - which hopefully will protect mooring lines from the mechanical damage inflicted by fish teeth.

    The surface acoustic shear sensor (SASS) as used during the Shelf Mixed Layer Experiment (SMILE) November 1988-March 1989 (2014)
    Woods Hole Oceanographic Institution
    Details
    Publication Date: 2022-05-26
    Description: The SMILE (Shelf Mixed Layer Experiment) field program took place during the winter of 1988-1989. The SMILE program itself was large and involved many investigators and instruments. This report documents the use of the Surface Acoustic Shear Sensor (SASS) as part of the suite of measurements taken during SMILE. The SMILE mooring array was deployed from early November 1988 until June, 1989. SASS, being a newly developed instrument, was deployed for two shorter periods; a test deployment between November 26 and December 8, 1988, and a longer second deployment, February 23 through March 14, 1989. SASS is based on BASS (Benthic Acoustic Stress Sensor) components (Williams et al., 1987), mounted on a structure that allowed continuous sampling of velocity, temperature and conductivity in the top five meters of the ocean. BASS was modified for this surface application to acquire data from a gyro, and conductivity sensors. The attitude data from the gyro allows the velocities of the current meter to be referenced to an inertial frame of reference. The other data obtained from SASS will be used to calculate shear current gradients, and other descriptors of turbulence and mixing.

    A vector-averaging wind recorder (VWAR) system for surface meteorological measurements in CODE (Coastal Ocean Dynamics Experiment) (2015)
    Woods Hole Oceanographic Institution
    Details
    Publication Date: 2022-05-26
    Description: As part of the Coastal Ocean Dynamics Experiment (CODE) field program, moored buoys were instrumented to measure and record wind speed and direction, air and water temperature, insolation, barometric pressure and relative humidity. Appropriate sensors were selected, necessary modifications to the sensors and existing current meters were made, and Vector Averaging Wind Recorders (VAWRs) were assembled. R. M. Young utility rotor and vane wind sets designed by G. Gill, Paroscientific Digiquartz pressure sensors, Eppley pyranometers and Hy-Cal relative humidity and solar sensors were used in two field experiments . Standard VACM direction and temperature sensors were maintained in the wind recorders. Devices were constructed as needed to protect against measurement errors due to wind, sun and ocean spray. Four W.H.O.I. VAWRs with Gill wind sensor sets were deployed CODE-1 in 1981. Seven VAWRs were deployed in CODE-2 in 1982. A modified VMCM (Vector Measuring Current Meter) was used for comparison in CODE-1, and the seventh VAWR deployed in CODE-2 carried an integral sensor set for comparison. Although several VAWRs had minor problems, all but one VAWR in the two experiments returned useful scientific data.
