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 a feature article titled Protecting Killer Whales in Salish Sea – Cabled Underwater Listening Station Monitors Ship Noise in the July issue of Sea Technology Magazine, JASCO Applied Sciences’ Nicole Chorney, Jack Hennessey, and David Hannay describe an advanced multi-sensor underwater observatory deployed off British Columbia’s south coast that keeps watch on noise from passing ships and has the ability to track endangered Southern Resident killer whales.

John Moloney is host to a Teledyne Webb Research webinar that describes the unique capabilities of JASCO’s OceanObserver acoustic and oceanographic data acquisition and processing system aboard the Teledyne Slocum Glider, as demonstrated in a successful mission to Canada's Gulf of St. Lawrence in 2018 in search of critically endangered North Atlantic right whales.

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.

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.
