icListen HF --Ocean Sonics’ smart hydrophones that are recognized as the new standard in broadband digital marine acoustics. 10 Hz to 200 kHz and a low frequency option from 1 Hz to 200 kHz.

icListen AF-- The ultra-low noise hydrophone is used for earthquake and tsunami monitoring, marine landslides and subsea volcano detection, vessel monitoring and low power deep-water projects. Bandwidth is 1.0 Hz to 1600 Hz.

icListen AF[L] -- This low-noise hydrophone bandwidth is extended to the audio band – 10 Hz to 12 kHz.

icTalk -- A projector that produces a series of tones, sweeps, pauses, or a combination of all three. Use as a stand-alone beacon or directly connected to a PC. Bandwidth of 10 Hz to 200 kHz.

Lucy -- Use for acoustic data display or to listen to acoustic data from the smart icListen hydrophones.


IcListen Accessories -- The Hub is used to connect up to 4 icListen hydrophones, and has both a processing mode and communication mode. The Ethernet Extender is used for hydrophone applications up to 1600m away from your PC. Batteries and cables are available, and the standard icListen instruments have rechargeable batteries, but for longer deployments standard D-cells are available.

SeaWATCH ADCP -- This is a compact and versatile instrument that produces precise current profile measurements over extended ranges, with a variety of frequency [300 kHz to 1200 kHz] and depth rating options [down to 6000m]. Can be deployed on buoys, moorings or sea-floor structures. Available in a dual beam configuration of 8 beams – all RoweTech systems have 8 channels capability.

SeaPROFILER ADCP -- This direct-reading instrument represents the industry state of the art in acoustic Doppler technology. The compact form factor, powerful electronics and robust signal processing, produces precise current profile measurements which are used for all RoweTech ADCPs. This ACP has extended ranges with a variety of frequency [300 kHz to 1200 kHz] and depth rating options [down to 6000m].

SeaTRAK ADCP -- This family of vessel-mounted ADCP’s represent the industry’s state of the art in acoustic Doppler technology which is capable of producing precise bottom-referenced velocity, current profile measurements, and echo intensity measurements. This unit is available in three frequencies: 300 kHz, 600 kHz, and 1200 kHz.

SeaPILOT ADCP -- This versatile DVL is well-suited for navigation applications in shallow water or in deep water, down to 6000m. This compact size, extended range, and precision make it an ideal solution for ROVs, AUVs, and other submersible platforms. There is also an OEM model which includes all the electronics and 4 Doppler transducers.

SeaWAVES ADCP -- The SeaWAVE ADCP 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.

SeaSEVEN ADCP -- Developed by the engineers that designed the first ADCP, RoweTech designed this unit based on their standard 8-channel processing system. This is the first coordinated seven-beam profiler on the market which has been designed with maximum flexibility for advanced research. Three frequencies are available – 300 kHz, 600 kHz and 1200 kHz.

The POPS platform provides meteorological and oceanographic subsurface data, transmitted via Iridium® telemetry (RUDICS). The system consists of five major elements: system controller (CPU), ice platform, meteorological sensors, Iridium® data telemetry, and GPS. In addition, POPS includes a subsurface CTD vertical profiling system.

PABLO -- This Iridium® acoustic platform was designed and tested to measure environmental acoustic ambient noise in order to detect the presence of marine mammals and to assess the impact of noise pollution. PABLO gathers acoustic data for the purpose of analyzing sound propagation in the top 1,000m of the ocean. Configured to collect data on a daily basis, PABLO has a long mission life, operating for close to a year while performing 300 profiles called acoustic window cycles.

NOVATECH Beacons -- The oceans are deep, vast, and for the most part—undiscovered. The NOVATECH™ Tracking & Monitoring products allow for recovery “peace of mind” in the deep, harsh ocean environments, for extended periods of time.
