    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (562 KB)

    Single-ship oceanographic cruises give way more and more to synoptic studies of the oceans. This new style of exploration is made possible by the appearance of the digital computer and its application in marine science in the last decade. High speed digital computers are not only utilized for faster processing of conventionally acquired data, but particularly in building descriptive and predictive... View full abstract»

    A gas generating (latent) buoyancy system or a fixed system comprised of solid buoyant elements can be employed in the recovery of instrument packages from great depths. The difference in characteristics of the two classes of recovery devices is discussed. The latent system offers better performance and fewer handling problems but at a higher purchase cost. It is consequently favored for emergency... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (358 KB)

    Submersibles provide a direct means of studying the living ocean resources. Basic submersible types include bathyscaphs, bathyspheres, tethered propelled subs and self-contained subs. Biological scientists require a submersible that is stable, can pinpoint and maintain its position, has variable speed with long endurance and provide excellent viewing and data monitoring systems. Few existing subs ... View full abstract»

    The quantitative assessment of fish stocks by acoustic signals is the most promising method of stock assessment for large areas of water. A prototype, SAS-I (stock assessment system) was put into operation April 1970 aboard the R/V Oregon II. It is a computer controlled data acquisition and reduction system which receives its source signal from the ship's echo sounder and prints out in tabular for... View full abstract»

    Of all the groups of animals considered as subjects for a radio tracking study, marine mammals probably present the greatest challenge to the engineer and biologist. In addition to special packaging problems associated with operating in the ocean, the fact that marine mammals spend most of their time submerged essentially precludes transmitting at RF frequencies. During the past 36 months, a serie... View full abstract»

    This project is four years old. The scope of this grand concept was to project man's technical capability to the limits of the ocean volume, and beyond, in support of National security and non-defense goals. Four years in the rational, financial world of DOD has changed the scope of the technology demonstrations but not the quality of the advanced technology goals originally set. The current proje...

    The results of a laboratory investigation of the wave induced forces on a submerged cylinder are reported. Force and pressure distributions on a cylinder located on and near a wave basin floor are correlated with surface water waves of varying amplitude and period. The horizontal and vertical components of forces on the cylinder are registered by strain gage outputs and by measuring pressure distr... View full abstract»
