JASCO’s PortListen framework powers internationally acclaimed initiative on ship noise

JASCO’s PortListen framework powers internationally acclaimed initiative on ship noise

The Vancouver Fraser Port Authority (VFPA, operating in the Port of Vancouver infrastructure) has received international acclaim for its initiative to incentivise quieter vessels by offering substantial discounts in its basic harbour rate to ships meeting prescribed underwater noise emission criteria. VFPA's Enhancing Cetacean Habitat and Observation (ECHO) program aims to better understand and manage the impact of shipping activities on at-risk whales throughout the southern coast of British Columbia. Key to this VFPA initiative is the ability to accurately assess underwater sound emissions from vessels as they navigate the access corridor to the port. This is enabled through the deployment and operation by JASCO Applied Sciences, in collaboration with Ocean Networks Canada (ONC), of Underwater Listening Stations that provide real-time automated measurements of vessels’ noise emissions relative to other ships in their class through JASCO's PortListen® solution – an ANSI-conforming acoustic measurement system and web-enabled user interface, supported by ONC’s subsea network and data archive.

Cynthia Pyć speaks at Consortium for Ocean Leadership workshop

The Consortium for Ocean Leadership held a workshop in October on Sound In The Sea: Building A Cross-Sector Consensus On Gaps In Science. Cynthia Pyć, Senior Manager of Environmental Science & Sustainability at JASCO Applied Sciences, was invited as an independent panelist. JASCO also provided major sponsorship of the event, which brought together a diverse group of delegates from the USA and Canada.

CBC News covers JASCO-supported Atlantic marine mammal study

On 16 May the Halifax, NS headquarters of JASCO Applied Sciences hosted a workshop attended by researchers from Fisheries and Oceans Canada and Dalhousie University to plan a coordinated effort to analyze whale calls in data that will be collected this summer as part of an unprecedented survey of marine mammals off Atlantic Canada. CBC News covered the workshop in broadcast and on-line articles about the search for the elusive northern right whale, which is one of the key mission objectives of the survey.

JASCO celebrates Earth Day 2016

JASCO celebrates Earth Day 2016

Earth Day was celebrated globally this year on 22 April, and the JASCO Applied Sciences team joined in the movement to keep the planet beautiful with two litter clean-up initiatives in the company’s Halifax and Victoria offices in Canada. JASCO members and friends gathered in numbers to tackle rubbish in local parks and neighbourhoods. The collected items were later sorted for recycling as far as possible. But personal involvement to helping the planet does not stop at just one day. A member of the JASCO team in the UK embraces the environment on a monthly basis by organizing litter clean ups in his community, and many others throughout company branches worldwide contribute in whatever way they can to reduce their environmental footprint every day of the year.

JASCO provides underwater noise measurement services to first offshore wind farm in North America

JASCO provides underwater noise measurement services to first offshore wind farm in North America

JASCO Applied Sciences is playing a key environmental role during the construction of the first offshore wind farm in North America near Block Island, Rhode Island.  

JASCO Applied Sciences, under subcontract to Tetra Tech Inc., is providing underwater acoustic measurement and monitoring services to Deepwater Wind during the installation of the Block Island Wind Farm. JASCO is conducting field data acquisition and subsequent analysis and interpretation for short- and long-term studies of noise from pile driving and related construction activities. The work is supported by staff from one of JASCO’s USA offices, located in Silver Spring, Maryland.

Fin whale song research

Fin whale song research

The September issue of Marine Mammal Research Newsletter features the article “Decoding the mysterious songs of fin whales” about a cetacean research project by Barbara Koot performed in collaboration with JASCO Applied Sciences.

Koot, who conducted the research as part of her MSc thesis at the University of British Columbia, used JASCO’s acoustic analysis software framework to process large datasets of underwater sound recordings and automatically detect fin whale calls. Fisheries and Oceans Canada, another collaborator in the study, supported the deployment and retrieval of acoustic recording instruments offshore the British Columbia coastline.

Port Metro Vancouver selects JASCO to help mitigate vessel noise impact on marine mammals in British Columbia

Port Metro Vancouver selects JASCO to help mitigate vessel noise impact on marine mammals in British Columbia

JASCO Applied Sciences (Canada) Ltd has been selected by Port Metro Vancouver and Ocean Networks Canada (PMV's News Release) to provide real-time passive acoustic monitoring of vessel traffic in the Strait of Georgia, BC, Canada, in order to study the potential impacts of shipping noise on marine mammals.

Two listening stations—each comprised of an AMAR Observer with a small spatial array of hydrophones and an AMAR Projector—were deployed on the major shipping route to Vancouver. These two systems are connected to shore in real-time via Ocean Networks Canada’s VENUS fibre optic cabled subsea observatory, which allows people and automated systems ashore to listen, measure, and characterize underwater sounds in the Strait of Georgia in real-time. AMAR Projectors calibrate and test the receiving arrays and will be useful in future planned experiments in underwater communications and navigation. These listening stations form part of the Enhancing Cetacean Habitat and Observation (ECHO) Program.

Real-time underwater sound monitoring of Bay of Fundy tidal berth sites

Real-time underwater sound monitoring of Bay of Fundy tidal berth sites

JASCO has begun monitoring and measuring underwater sound at the Fundy Ocean Research Center for Energy (FORCE) tidal energy berth sites in the Bay of Fundy, Parrsboro, Nova Scotia.

The cabled monitoring system, designed and assembled in Dartmouth, Nova Scotia, is “world-leading ocean technology that helps protect our marine environment,” said Scott Carr, CEO of JASCO Applied Sciences. It is deployed on FORCE’s Fundy Advanced Sensor Technology mini-platform, an underwater framework that captures data from the site with onboard sensing equipment. “To harness the enormous power of the Bay of Fundy responsibly, we have to understand it. The FAST platforms give us a clearer, moment-by-moment picture of what’s happening under the water,” said FORCE general manager Tony Wright.
