Marine scientists in British Columbia are optimistic about adopting a new strategy for whale monitoring, inspired by a successful initiative in California. In San Francisco Bay, a coalition of researchers, ferry operators, and the public is employing innovative technology, including an app and specialized thermal imaging cameras known as WhaleSpotter, to keep track of whale movements around the clock. These cameras, compactly stored in white boxes resembling microwaves, capture thermal images of whales, which are then shared on a public app in conjunction with human sightings.
Daniel Zitterbart, the lead scientist at WhaleSpotter, emphasized the significance of increased surveillance on the water to enhance whale protection. While similar WhaleSpotter cameras are operational in British Columbia, they are currently only stationed on land, limiting their surveillance range to approximately two nautical miles. Monitoring whale activities is crucial for identifying their migration paths and averting potential vessel collisions, a growing concern in British Columbia evidenced by recent documented incidents involving whale fatalities.
In San Francisco Bay, the WhaleSpotter cameras are integrated with the Whale Safe app, enabling scientists, mariners, researchers, and the general public to monitor whale sightings collaboratively. This community-driven effort to build a shared resource was commended by Douglas McCauley, the director of Benioff Ocean Science Laboratory. In British Columbia, access to the camera data is restricted to approved commercial mariners through the Ocean Wise whale report alert system, with plans to potentially expand public access in the future.
Thomas Hall of San Francisco Bay Ferry emphasized the value of tracking whale behavior over time using ferry-mounted cameras to adjust routes accordingly. Advocating for broader implementation, Zitterbart expressed his desire for B.C. Ferries to adopt similar monitoring systems to safeguard whales traversing their routes, especially the renowned “humpback highways.” B.C. Ferries has shown interest in deploying detection devices on its northern route following a fatal humpback whale collision last year.
The need for enhanced collaboration in whale protection efforts has intensified as marine traffic surges and climate change disrupts traditional whale habitats. Researchers in San Francisco Bay noted an uptick in grey whale sightings as these creatures seek new feeding grounds during their northbound migration. Despite progress, vessel strikes remain a significant threat to whale populations, necessitating coordinated actions across borders to ensure their safety and conservation.
Sean Brillant, a conservation biologist at the Canadian Wildlife Federation, stressed the urgency of addressing vessel strikes as a global issue requiring concerted efforts and data sharing among various stakeholders. The success of conservation endeavors hinges on collective action and information exchange to mitigate risks posed to whale populations worldwide.
