Anthropogenic noise has increased drastically in recent years due to the rise in ocean infrastructure development. Pile driving, the practice of pounding long hollow steel pipes called piles into the ocean floor, is required to support underwater structures such as turbines.
Pile driving is used to dill turbines into the ocean floor for the purpose of tapping into natural energy sources such as oil, gas, and wind. Pile driving is also used to build bridges and piers. Pile driving has the potential to produce some of the loudest anthropogenic sounds that enter the marine environment.
Bridges and piers are subject to guidelines and regulations during their construction phase. Environmental assessments have to to made concerning the marine environment as noise pollution can have detrimental effects on local ecosystems.
Tidal energy is a renewable source of electricity which does not result in the emission of gases responsible for global warming or acid rain associated with fossil fuel generated electricity. Tidal barrages don’t change the natural landscape and are environmentally invisible, making tidal energy a truly clean and renewable energy option.
Unlike wind and waves, tidal currents are far more predictable and reliable. We can predict the movement of the tides today, tomorrow, and 300 years from now.
Tidal barrages are undersea tidal turbines, like wind turbines but driven by the sea, harnessing undersea currents. Tidal turbines do not have to spin as fast as windmills to generate power, because water is roughly 800 times more dense than air. Energy can be harnessed from the tides in two ways: using the change in height of the tides; and using the flow of the water. These dam like structures allow the free flow of the water masses in bays and rivers, capturing only the energy instead of the body of water unlike traditional dams, turning tidal currents into reliable and predictable sources of renewable energy
The world’s tides, ocean waves, and river currents all contain kinetic and potential energy that can be used to drive turbines and produce electricity—reducing our dependence on fossil fuels.
Waves are created when wind blows across the oceans surface. In many coastal areas, the wind blows with enough consistency and force to generate near constant wave activity along shorelines.
Wave energy is measured and distributed in 60-hertz frequency. Hydrophone technology, including radio buoys and smart digital hydrophones, is used for wave forecasting. Using sound measurements can help improve the reliability and predictability of wave energy.
Unlike wind, which tends to slow in the mornings and evenings, and solar which is only accessible during daylight hours wave energy can be harnessed 24/7. Improving the way we predict, generate, and distribute wave energy will make our oceans an endless supply of energy that is renewable, pollution-free, and environmentally invisible .
Environmental monitoring information is used by many people to make informed decisions about the environment. Timely and effective responses to environmental emergencies, such as a oil pipeline leak, are impossible without adequate information. Hydrophones can be used as acoustic leak detectors because they identify the sound or vibration induced by water escaping from pipelines under pressure. When pressurized water leaks from a pipe it creates a sound or an acoustic signal that can travel through both the pipe wall and the water column in the pipeline.
Empowering woman in STEM: Jillian Duggan completes the Passive Acoustic Monitoring Operators course, the first of its kind offered in Canada
Jillian Duggan, 25, the marine biologist and ocean technologist working at Ocean Sonics is a newly certified PAM, passive acoustic monitoring, operator. Duggan passed the Edgewise Environmental PAM operators course with merit last week in Newfoundland. Continue reading

Ocean Sonics, a leader in smart hydrophone technology, has developed a coastal acoustic drifting buoy. Practical uses include but are not limited to marine mammal monitoring, real-time noise measurement, environmental assessment and improving compliance with the Marine Strategy Framework Directive.
The killer whales around Vancouver Island need our help to protect them from the effects of human activity. Ocean Sonics has stepped up to the challenge with its novel hydrophone network.
Ocean Sonics is excited to announce the release of the newest icListen HF Smart Hydrophone. The SC2-ETH follows the very popular SB2-ETH with its small size and smart electronics, setting the standard for smart digital hydrophones!
- Low Power: Get longer deployments thanks to its lower power. Use as an Acoustic Recorder
- Connect with 24 or 12 V: Use 24 V for best performance on longer cable runs. Short cables can use 12 V for highest battery efficiency
- Large Memory: Double the data collected with the 256 GB internal memory. For even more memory, ask about the New Acoustic Digital Recorder.
- Track Time Accurately even when the icListen is powered off. You can guarantee instrument time is accurate by connecting to your laptop, or to a GPS for Sync
- Hydrodynamic Shape: Record higher quality data in flowing and turbulent water
- Eliminate Electro Magnetic Noise from the power supply ‘hum’ even in challenging environments
Enjoy all the icListen features you currently enjoy and more. The SC2-ETH is fully compatible, and can be directly combined with other members of the icListen family.
