Collecting ocean sound data has never been easier with the Coastal Acoustic Drifting Buoy. Designed with the user in mind, the buoy weighs in at 23KG and measures 1 meter in length and 0.5 meters in width and is easily deployed by a singular user without the use of a crane or any additional equipment. Features include Wi-Fi for real-time set-up, status and spectral display, remote WIFI access (up to 100m), GPS time sync, on/off switch for icListens and buoy, and hydrophone synchronization within one microsecond.
Designed to be acoustically quiet, this buoy has the ability to drift and collect data or to be moored. While drifting the buoy reduces flow noise to improve quality and clarity. With configuration for up to 6 hydrophones or other Ethernet devices, this buoy integrates easily into any project.
“Ocean Networks Canada performed a wide range of tests on the hydrophones prior to deployment to verify the manufacturer’s specifications. The hydrophone instruments met all the manufacturer’s specifications and were easy to use. Both models satisfy our requirements for dynamic range, sensitivity and, most importantly, reliability. When coupled with the fast and friendly customer support we have received, these LF and HF hydrophones are a good choice for our ocean observatory.”Tom Dakin Sensor and Technology Business Development Officer and Resident Ocean Acoustician Ocean Networks Canada
“We have been working with Ocean Sonics in our technology demonstration program since the first prototypes. Our science users have been very impressed with the very high quality data sets. Ocean Networks Canada is expanding our hydrophone network with Ocean Sonic icListen HF smart hydrophones across our observatory including new sites across coastal BC, as part of the Smart Oceans™ program. The compact size, Ethernet interface, high reliability and exceptional performance make these systems ideal for ocean observing applications such as mammal classification, vessel and ambient noise studies.”Scott McLean Director(Former) Ocean Networks Canada
“I have used many different hydrophones on different systems, but these icListen hydrophones are the best I’ve seen in many years. They’re calibrated to very low frequencies where I’ve never been able to get reliable data.”
Ross Chapman Professor Emeritus University of Victoria
The Ocean Observatories Initiative (OOI) Regional Scaled Nodes (RSN) had requirements for very broadband hydrophones with good noise floor characteristics and a wide dynamic range. The icListen HF hydrophones satisfied these requirements at a reasonable cost. The hydrophones were quite easy to use out of the box, and easily passed our intensive First Article tests centered on assuring any instrument will not interfere with or corrode any other instrument. Customer support has been quite good, with very detailed questions answered quickly and accurately.
