The system consists of two parts, a trawl resistant sub-surface component and a separate surface buoy. The sub-surface component employs a trawl resistant bottom mount containing an acoustic Doppler current profiler equipped with a Micro-Modem (/spl mu/Modem). The surface expression consists of a buoy equipped with an acoustic receiver (Utility Acoustic Modem, or UAM), a system controller and an Argos transmitter (PTT). The /spl mu/Modem acoustically telemeters data from the ADCP on an hourly schedule to the UAM on the nearby (/spl sim/500 m) surface buoy. Data from the acoustic receiver are forwarded via the controller to the Argos transmitter. To maximize data throughput of the Argos link, the controller loads a circular buffer containing the most recent eight hours of data into the PTT each hour. These data are continuously transmitted until the next hourly update. The controller also performs resynchronization of the acoustic system in the event acoustic communications are lost. One particular benefit of this system is the ability to perform measurements in high traffic locations while maintaining the surface buoy at a safe distance from navigation aids. One system is currently deployed in a high traffic area, in Horn Island Pass, due south of Pascagoula, Mississippi. This paper describes the overall system and presents data from initial deployments.","PeriodicalId":326183,"journal":{"name":"MTS/IEEE Oceans 2001. An Ocean Odyssey. Conference Proceedings (IEEE Cat.

The results shown concentrate on the source localization and ocean tomography data sets. The data gathered during a 24 hour run along a range independent track shows strong oceanographic features, possibly due to internal tide signature, both on the temperature data, as measured on the thermistor chain collocated with a vertical line array (VLA), and on the acoustic data. A range dependent track between 120 and 60 m water depth, shows a highly variable channel impulse response along time and range when the source was moving outwards from the VLA. In another acoustic track, the source was navigatated across a underwater canyon where the energy was rapidly distributed over a deep acoustic channel with sound trapped well below the thermocline. Good agreement between the modeled and measured channel responses represents the first step towards matched-fleld processing-like methods such as source localization and tracking and ocean tomography.","PeriodicalId":326183,"journal":{"name":"MTS/IEEE Oceans 2001.

A high frequency (/spl sim/3.5 kHz) phase conjugation array (HFPCA) has been designed, fabricated, and deployed at sea in two experiments (July 1999 and May/June 2000) conducted jointly with the NATO SACLANT Undersea Research Centre. The HFPCA consists of 29 source/receive transducers equally-spaced over an aperture of 78 m and operating nominally in the 3-4 kHz band, an underwater pressure case containing the source/receive electronics, and a surface buoy providing battery power, system control, and wireless local area network (LAN) connectivity. On receive, the sampling rate for each channel is f/sub s/=12 kHz. On transmit, an arbitrary waveform can be transmitted independently from each transducer (10.7 sec maximum duration) at a maximum source level of 180 dB re 1 /spl mu/Pa per transducer. The wireless LAN enables received data segments to be telemetered to the support ship up to 30 km away for immediate processing. Transmit waveforms (e.g. time reversed versions of the received data segments) also can be telemetered to the surface buoy for downloading into the electronics and transmission.","PeriodicalId":326183,"journal":{"name":"MTS/IEEE Oceans 2001.
