Bruce Martin hosts OERA Webinar: How Does Sound Travel in High Energy Environments?

Bruce Martin hosts OERA Webinar: How Does Sound Travel in High Energy Environments?

On December 10, 2020 Dr. Bruce Martin hosted a webinar titled “How Does Sound Travel in High Energy Environments? Effectiveness of Acoustic Monitoring Systems and Turbine Audibility Assessment”.

To support tidal energy development in the Bay of Fundy, researchers are designing and implementing a long-term acoustic monitoring program. In preparation, specialized acoustic instrumentation was deployed for two months in Grand Passage to better understand how the turbulent waters affect our ability to detect marine mammals, and to what extent these animals can detect a tidal turbine.

Hearing in the Dark

Hearing in the Dark

Roberto Racca and Klaus Lucke of JASCO Applied Sciences dive into the soundscape of the abyss in ECO Magazine’s Deep Sea special issue:

Life in the depths is adapted to wholly different conditions than exist near the surface, with increasingly high static pressure and decreasing or no light. Here, animals create their own light through bioluminescence. What of their hearing abilities? To understand how deep-sea animals perceive their environment, a group of Australian experts joined an international research expedition in the Indian Ocean. The question was whether deep-sea fish have a keener sense of hearing compared to their shallow-water counterparts.

Klaus Lucke's DOSITS webinar shines light on underwater noise regulations around the globe

Klaus Lucke's DOSITS webinar shines light on underwater noise regulations around the globe

JASCO scientist Dr. Klaus Lucke hosted an informative webinar titled Regulatory Approaches to Underwater Noise – An International Comparison. He provides an overview of the most prominent national and international noise regulations. Focussing entirely on marine mammals, parallels and differences in approaches taken by countries, regional agreements, and multinational organisations are presented.

Listening to the Chukchi Sea

Listening to the Chukchi Sea

In the recent Polar special issue of ECO Magazine, JASCO’s Roberto Racca and David Hannay describe how an ambitious acoustic monitoring program helped advance our understanding of Arctic ecology:

From 2006 to 2015, several oil and gas companies performed exploratory campaigns … in the northeastern Chukchi Sea. Some of these companies funded multidisciplinary long-term environmental projects to collect ecological baseline measurements and inform regulatory permit applications. The Chukchi Sea Environmental Studies Program (CSESP), the largest of these multi-year studies, included a large passive acoustic monitoring component. Led by JASCO Applied Sciences, the acoustic element of the program enabled scientists to describe how vocal marine mammals use the northeastern Chukchi Sea throughout the seasons, and to characterize the natural and human-made soundscape of the area.

Alutasi: A green launch into the blue

Alutasi: A green launch into the blue

A milestone in ecologically friendly marine transportation for Atlantic Canada was reached on Aug. 12 with the launch ceremony of the first Cape Islander style vessel to be refitted for electric propulsion. The Peggy’s Cove Express, a diesel-powered tour boat (formerly a fishing vessel), was converted to a hybrid system with a clean, battery-powered electric motor in parallel with the original diesel engine. Renamed the Alutasi, this vessel will be Canada’s first Transport Canada Marine Technology Review Board approved boat using electric propulsion powered by lithium-ion batteries.

JASCO measured underwater noise from the original power train, testing various combinations of transit speed. loading conditions and propeller wear, and will soon repeat the measurements for the newly installed electric propulsion system to quantify the environmental benefits of going electric for this style of vessel.

A Quiet Day on the Reef

A Quiet Day on the Reef

Cynthia Pyć, Klaus Lucke, and Roberto Racca of JASCO Applied Sciences contributed an article to the recent Coral Reefs special issue of ECO Magazine.

The COVID-19 pandemic has resulted in the near shut-down of international tourism and the imposition of port closures and transit restrictions, significantly decreasing the volume of global ocean-going vessel traffic. A 2017 Caribbean coral reef acoustic monitoring study that serendipitously coincided with Tropical Storm Franklin could provide some early insight on the quieter soundscape that coral reef inhabitants are currently experiencing.

JASCO supports Black Lives Matter

JASCO supports Black Lives Matter

JASCO Applied Sciences takes a knee in solidarity with Black Lives Matter.

JASCO’s leadership and global team uphold the respect of human dignity and the value of every person as our guiding principle. We stand in full support of a communal push for humankind to reject all forms of discrimination and prevarication of one individual or group over any other.
–Roberto Racca, JASCO's Chief Communications Officer

As many of us pause and ponder how we, ourselves, can shape and support this long-overdue movement, we’d like to share some resources.

Craig Evans wows 4th graders with sound science

Craig Evans wows 4th graders with sound science

For ten years, Craig Evans has helped make the science curriculum exciting for the kids in Mrs. Tracey Evans’s classroom. Every year Craig teaches the fourth graders at Grosvenor-Wentworth Park Elementary about sound energy and how humans and animals use sound to communicate, even under water. After listening to some animal sounds, the children get to see which ones they sound like with JASCO’s educational DORI software, which stands for Detecting Oceanic Real-time Impersonations. The students thanked Craig and JASCO with dozens of beautifully illustrated cards.
