Port of Vancouver expands geographic areas of ECHO program

The Port of Vancouver reminds the shipping industry that as of June 1 the commercial shipping sector is alerted to begin voluntarily slowing their ships southern resident killer whales return to Haro Strait and Boundary Pass to feed for the summer. 

Addressing underwater noise created by dredging

Underwater sound created by dredging equipment below the water surface can impact marine life and requires careful evaluation and monitoring, according to the International Association of Dredging Companies. Sound levels must be evaluated in relation to their possible effect on the specific marine fauna. The aim of evaluating underwater sound is to ensure a balance between the environmental impacts and socio-economic benefits of the dredging project.

Notation on reducing marine noise

RINA, the Italian Classification Society, focused on the matter of noise coming from vessels, as the majority of noise is emitted underwater, thus the public is unaware of the problem. Yet, marine noise results to the interference of animal’s ability to hear, having a huge impact the reproduction and survival of animals.

UK creates first map of underwater noise

UK unveiled the first UK-wide map of underwater noise made by ships. Researchers from the Centre for Environment, Fisheries and Aquaculture Science (Cefas) in Suffolk used data captured from microphones placed on the seabed to identify “hotspots”.

Project NEPTUNES aims to mitigate noise pollution in the marine environment

In 2017, a small group of pioneering ports created an inventory ship-generated noise in berth, at anchor and manoeuvring to get in berth or leaving the berth. The project NEPTUNES – Noise Exploration Program To Understand Noise Emitted by Seagoing Ships –  aims to mitigate the noise pollution from seagoing vessels.

European countries must take action to reduce underwater noise, report says

A recent report by OceanCare, International Fund for Animal Welfare, Seas at Risk and Natural Resources Defense Council, found that the EU could fail to protect marine wildlife from the impacts of intense underwater noise levels by 2020, despite a requirement to do so under EU marine law. The report raises concerns that despite evidence that noise sources are damaging marine species, some governments continue to call for further research instead of taking action.

The anthropogenic sound harms the ocean wildlife

The Standard Club focused on the matter of ‘anthropogenic sound’, meaning the noise pollution that prevents ocean wildlife organisms from communicating with one another, perceiving prey or finding potential mates.

Vancouver port lists Wärtsilä’s EnergoProFin in EcoAction program

Finnish technology group Wärtsilä’s EnergoProFin, an energy saving propeller cap, which delivers average fuel savings of 2%, has been listed in the 2019 Vancouver Fraser Port Authority’s EcoAction Program. The Program provides harbour dues discounts for vessels calling on the Port of Vancouver that meet environmental best practices.

Port of Vancouver expands noise reduction features in protection of whales

The Vancouver Fraser Port Authority has expanded its industry-leading EcoAction Program, encouraging vessels that call on the Port of Vancouver to quiet the waters for the endangered whale population along the southern coast of British Columbia. Specifically, the program got into force on January 1, 2019.
