4 SeaWATCH / SeaPROFILER ADCP Self-Contained and Direct Reading 150 khz / 78 khz ADCP The ROWE Technologies SeaWATCH family of self-contained Acoustic Doppler Current Profilers (ADCPs) lead the industry in state of the art acoustic Doppler technology. ROWE s second generation electronics provide higher power operation needed for lower frequency [78 khz and150 khz] ADCPs. The SeaWATCH systems are offered in both conventional piston transducers, and the newly designed ROWE Doppler Array. The performance characteristics of both piston transducers and Doppler Array configurations are similar, but the Doppler Array system dramatically reduces the unit s volume and weight requirements. This, combined with the next generation of ROWE compact electronics and robust signal processing, provides a versatile ADCP platform, capable of producing precise current profile measurements over extended ranges out to 1000km. ROWE s Doppler Array technologies offer unique benefits, especially in low frequency systems where the size of the transducers dominate the overall ADCP volume and weight. These Doppler Array surfaces are flat, and form acoustic beams with characteristics equivalent to conventional piston transducers, but use approximately 50% less frontal area, volume and weight. ROWE Doppler Arrays can form up to 9 acoustic beams (at 0º, 4 at 20º, and 4 at 30º) unlike existing piston technology which uses four fixed beams in a Janus configuration. The ROWE Doppler Array design increases measurement flexibility for better velocity accuracy (30º beams), improves range (20º beams), or generates a highly accurate altitude/ (single broadside beam).

16 SeaWAVE ADCP SeaWAVE 300 khz / 600 khz / 1200 khz The Rowe Technologies SeaWAVE product family of Acoustic Doppler Current Profilers (ADCPs) represent the industry s state of the art in acoustic Doppler technology. The SeaWAVE ADCP measures wave direction and wave height while also providing full current profile data even throughout the wave burst interval. The SeaWAVE simultaneously measures wave spectra, wave direction, and complete current profiles for every ping. The SeaWAVE can also measure current profiles during the wave burst interval, so you can get full velocity profile coverage during your deployment. The SeaWAVE uses both a vertical beam and a pressure sensor to accurately measure range to the surface. The vertical beam functions similar to an inverted echo sounder providing more accurate, higher frequency wave measurements. The SeaWAVE wave measurement ADCPs are available in both the direct-read and self-contained configuration. WaveForce Technologies [ partnered with Rowe Technologies, Inc., offers ocean wave data analysis software packages -- both a real-time and post-processing software suite that interfaces seamlessly with the SeaWAVE ADCP outputs.
