Ocean Sonics has recently commissioned a new state of the art digital hydrophone calibration lab, the only one known of its kind, at their office in Great Village, Nova Scotia, Canada.

The traditional analog approach to calibrating hydrophones is a tricky and demanding task. Digital hydrophone calibration greatly simplifies the calibration process.

The separate wood framed building sits above the ground to isolate it acoustically. A Faraday cage shields instruments from electromagnetic radiation that could interfere with low signal measurement. Power is isolated from the main building and the data is wired to the main building to allow remote operation. The lab facility features a large test tank with room to fit multiple icListen Smart Hydrophones and an icTalk Smart Projector as the sound source. Each icListen hydrophone comes with a calibration certificate indicating when it was tested and the result. Ocean Sonics recommends returning the hydrophone unit for recalibration every two years. Read more…

Ocean Sonics Ltd. focuses on sound for survival

If you suffer from ringing ears or a bit of temporary hearing loss after a noisy rock concert, it doesn’t affect your ability to survive. But Mark Wood, president of Ocean Sonics Ltd., says many undersea creatures are dependent on sound to survive.


“These animals are deep under water where there’s no light, and they’re dependent on sound to locate food,” says Wood. “If they go deaf temporarily, it makes them vulnerable to predators, or they might beach themselves accidentally.”


If you’re building a bridge, for example, you need to be monitoring the noise you’re making in the water.


“Construction is very noisy, so if you’re pile-driving, the area near the work site has enough energy that it can actually kill fish,” says Wood. “We enable our customers to protect the health — and safe the lives — of animals.”…Read more

Great Village’s Desiree Stockerman Talking to the Nova Scotia Premier Stephen McNeil

“We need to stop dividing our province. There are good things (here) … we need to focus on the positive things and not continue to focus on the negative things,” the premier suggested during a Truro and District Chamber of Commerce breakfast in Truro on Friday morning. About a 100 people were in attendance.

That doesn’t mean overlooking some obvious challenges, such as having the “worst performing economy for the last 11 years” and a

70 per cent population that is struggling, he said.

Instead, McNeil said, things such as encouraging sector development as opposed to financing private sectors, investing in sector infrastructure, and finding creative avenues to be profitable should be implemented….Read More

Tide to Technology: Sea the Connection

Halifax, Nova Scotia, April 12th, 2014  

The Discovery Centre in partnership with the Ocean Technology Council of Nova Scotia (OTCNS) and the Aerospace and Defence Industries Association of Nova Scotia (ADIANS), under the auspices of Labour and Advanced Education Ocean Sector Council,  launched the “Tide to Technology” program on Saturday, April 12th at the Discovery Centre.

Tide to Technology is an external science program that offers high school students an opportunity for hands-on learning with up-to-date ocean technologies and a chance to interact with local industry representatives.

ROV Challenge 2014

2014 ROV Challenge – NSCC Akerley Campus Friday April 11, 2014.

The ROV competition challenges high school students from Nova Scotia to design and build ROVs to tackle missions modeled after scenarios from the ocean workplace. The ROV competition requires students to think of themselves as “entrepreneurs” and transform their teams into companies that manufacture, market, and sell “products.”  In addition to engineering their ROVs, the students are required to prepare technical reports, poster displays, and engineering presentations that are delivered to working professionals who serve as competition judges.

Representing Ocean Sonics at the 2014 ROV Challenge was President Mark Wood, and Marketing Coordinator Lauren Dolan.  Wood judged the technical presentations, while Dolan judged the pool side ROV missions.

New X2 option for the icListen HF to be released at OI’14

icListen HF-X2

Ocean Sonics is pleased to announce the new icListen HF-X2 also known as the high intensity option or reduced sensitivity option.
 This Smart Hydrophone is ideally suited to monitoring pile driving, construction noise and explosions.
The X2 offers all the same features of the standard icListen HF but with its reduced analog input gain, it records peak sound levels greater than 210 dB re.uPa without clipping or saturating. Use the Event Detection feature to ensure loud events are recorded or send an event message when a preset sound level is exceeded.

Ocean Sonics welcomes two new hires

Ocean Sonics has announced the appointment of two new engineers to the icListen team. David Sampson joins the team as a Production/Calibration Engineer, while Mithun Ceekala joins as an Analog Design Engineer.

"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.
