    The scientific objective of the system presented in this paper is to conduct in situ measurements of environmental parameters and to support several marine in situ experiments which are carried out in order to investigate the interaction between the sea and the sea bottom in shallow-water ecosystems. Automated in situ measurements are carried out by means of the radio-controlled data acquisition a... View full abstract»

    The use of passive sensors to estimate range and bearing to an acoustic source is investigated. The variance of the estimators is shown to depend on the number of sensors, integration time, signal-to-noise ratio, and more significantly, on the available array length. The variances for four different array configurations are discussed. View full abstract»

    A cheap and mechanically simple bottom-finding device uses a single trip weight and a mercury switch to change the dc resistance of an electromechanical cable when the trip weight hits the sea bottom. The change is detected in a deck unit which sounds a loud alarm on an exterior speaker near the winch operator. The deck unit also displays the cable dc voltage and current. View full abstract»

    The SeaSat-A satellite scatterometer is a microwave sensor designed to provide a capability for mapping the global ocean surface wind speed and direction. Four fan beams whose major axes are oriented at \pm45 and \pm135\deg to the flight vector cover a swath width of 1900 km, but a central region remains that is inadequa... View full abstract»

    This paper presents a detailed description of two underwater connectors and a feedthrough that can be designed in-house for special requirements. A standard MIL-C-24217 underwater connector can be used for many applications, but frequently a special design would do the job much better. A special design, however, usually involves severe penalties in cost and delivery. This paper describes technique... View full abstract»

  • Parametric acoustic source beamwidth control

    In addition to its narrow beamwidth and wide-band capability, the underwater parametric acoustic source has the advantage of maintaining a relatively constant beamwidth over a wide range of difference frequencies. However, for some applications, the beamwidth of the difference frequency is narrower than desired or an adjustable beamwidth is required. This article describes techniques by which the ...

Aims & Scope

The IEEE Journal of Oceanic Engineering (ISSN 0364-9059) is the online-only quarterly publication of the IEEE Oceanic Engineering Society (IEEE OES). The scope of the Journal is the field of interest of the IEEE OES, which encompasses all aspects of science, engineering, and technology that address research, development, and operations pertaining to all bodies of water. This includes the creation of new capabilities and technologies from concept design through prototypes, testing, and operational systems to sense, explore, understand, develop, use, and responsibly manage natural resources.
