Description

The Rowe Technologies SeaWATCH product family is the most versatile self-contained Acoustic Doppler Current Profilers (ADCPs) and represent the industry state-of-the-art in acoustic Doppler technology. The compact form factor, powerful electronics and robust signal processing, provide a versatile platform capable of producing precise current profile measurements over extended ranges.  The product comes in three different frequencies; 300 kHz, 600 kHz, and 1200 kHz, and is available in different depth package options – 300 m, 3000 m, and 6000 m.  Each unit in the product family leverages a core, common set of electronics in a flexible form factor. This, combined with multiple packaging options, provides a cost-effective and extremely capable instrument to address a wide variety of oceanographic applications, from shallow water to full- ocean depth.  The SeaWATCH ADCP’s are well suited for a variety of coastal and offshore oceanographic applications including meteorological and wave data acquisition, environmental management, coastal engineering site assessment, and oil/gas exploration and drilling.  Rowe systems are easily deployed on buoys, moorings, or sea-floor structures.

  • Typical applications
    ROWE’s second generation electronics provide the ability to use two independent acoustic frequencies in the same instrument. Each of the frequencies can be independently controlled allowing for near simultaneous acquisition of high resolution, short range current profiles from the high frequency channels, and long range, lower resolution profiles for the low frequency channels.
