A landmark publication in the research on western grey whales and seismic survey noise
/
A landmark Topical Collection on Western Gray Whales and Industry Seismic Operations of 10 peer-reviewed original articles has been published in the journal Environmental Monitoring and Assessment. This comprehensive collection arises from decades of studies of the effects of offshore oil and gas development on the grey whales that gather every summer off Sakhalin Island, Russia. JASCO scientists were involved since 2004 in the underwater acoustics field work and analyses that fed into these papers, in addition to contributing to the yearslong real-time mitigation effort that ensured whales would not be exposed to excessive sound emissions from offshore activities and airguns.

/
As described in a recent article in MarineLink, BC Ferries has some key findings to pass along to other vessel operators considering the implementation of underwater radiated noise targets. Important lessons were learned during investigations of how they might reduce the noise from their passenger ferries transiting the Salish Sea, which is home to the endangered southern resident killer whales (SRKWs).

/
In the May issue of Ocean News & Technology, JASCO’s Chief Communications Officer Roberto Racca gives a panoramic on new mobile platforms apt to be equipped with acoustic monitoring instruments to both detect the presence of vocalizing marine animals and assess their exposure to noise from construction and operation of offshore wind farms.
Read MoreVessel receives first quiet ship recognition
/
A merchant vessel has received the first ever underwater environmental noise emissions notation from an international vessel certification organization. The newly built Onex Peace, an Aframax class crude oil tanker built by Hyundai Samho Heavy Industries and delivered to Onex, received DNV’s first SILENT-E notation on its class registration, making it the world’s first commercial vessel to receive this type of notation. The notation is part of a larger effort to encourage ship owners and builders to lower the ecological footprint of their vessels.

/
A video production featuring thoughts and recollections from some of the preeminent scientists of the past half century in the field of underwater acoustics has been published by the Institute of Acoustics and the UK Acoustics Network to celebrate the 50th anniversary of the A B Wood medal. The medal with attendant prize is awarded in alternate years to acousticians based in the UK/Europe (even years) and in the USA/Canada (odd years). One of the 24 medal winners featured in the video is Dr. Michael Ainslie, a senior scientist with JASCO Applied Sciences based in the Netherlands.

/
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.

/
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.

/
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.
Read MoreListening 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.

/
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.

/
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.
