GREAT BEAR SEA, B.C. —A new report by WWF-Canada uses data on ship speed and waste generated in B.C.’s Northern Shelf Bioregion, also known as the Great Bear Sea, to show the extent to which significant shipping traffic in one of the country’s rapidly developing coastal regions poses a direct and urgent threat to the region’s endangered cetacean species.
The analysis shows that shipping speeds, combined with billions of litres of waste, pose immediate and cumulative risks to species at risk, including fin whales and humpbacks. It builds on the data and findings from WWF-Canada’s Shipping Traffic and Speed in Cetacean Habitats on Canada’s Pacific Coast and National Vessel Dumping Assessment.
In 2022, an estimated 56 billion litres of waste were generated by commercial ships in the Northern Shelf Bioregion. When compared to an estimated 203 billion litres of harmful waste dumped in Canadian waters each year, the region represents a staggering 27 per cent of the estimated country-wide total.
And while “discharge” describes a range of waste types – including sewage, greywater (from sinks, showers, bathtubs, kitchens and laundry), and industry-specific waste such as oily bilge water – more than half of the bioregion’s waste was from scrubber washwater, a mixture of seawater and dissolved metals, acids and other harmful compounds. Since 2017, the number of ships fitted with scrubbers globally has increased by 1,500 per cent.
The harmful substances present in ship discharges have been linked to serious health problems in whales, fish and invertebrates, problems such as decreased fertility, compromised immunity, and increased rates of cancer, deformities and mortality.
The analysis shows a geographical correlation between ship speed and discharge (i.e., dumping of waste), where the highest regular concentration of ships travelling more than 10 knots — that is, at speeds that are far more likely to be lethal to whales if struck — is also where discharge volumes are highest. These areas also intersect with critical whale habitat, placing these species at high risk and increasing the urgent need for mitigation measures.
This looped image shows critical and important habitat (in yellow and orange) for at-risk whale populations and both ship speed and discharge data that was visualized as part of the WWF-Canada report (in purple and blue). The results are clear: excessive ship speed and shipping-related pollution are concentrated where critical whale habitat is observed, placing these species at high risk, and making the need for mitigation measures more urgent.
Given these clear results, WWF-Canada calls on industry and government to immediately:
