FEASIBILITY STUDY OF A SEDIMENT POD FOR SUBMERSIBLE USE.
Abstract
The objective of the SEDOPOD Study Program is to provide the Naval Oceanographic Office, Deep Vehicle Branch with information necessary to design, purchase, and fabricate a sensor package capable of measuring several mass properties of unconsolidated bottom sediments. The resulting design shall be deployed by a submersible vehicle which shall make in-situ measurements and record at several bottom locations. The device will measure in the sediment the parameters of sound velocity, attenuation, density, temperature, shear strength, and Eh/pH in water depths to 20,000 feet with 3 foot sediment penetration. This report covers the approaches used to investigate the state-of-the-art of available sensors including an extensive literature survey, visits, interviews, and contacts with suppliers and users of sensors and related instrumentation. This investigation involves a determination, where possible, of availability, cost, life expectancy, power, size, weight, reliability, and accuracy. Where sensors do not exist to perform in the environment or meet the stated requirements, a determination of the amount of development necessary has been made. (Author)
