Marine researchers in British Columbia are exploring a novel approach to whale monitoring inspired by a successful project in California. In San Francisco Bay, a collaborative effort involving scientists, ferry operators, and the public is underway to track whale movements using a specialized camera system and a dedicated app.
The WhaleSpotter cameras, compact units equipped with thermal imaging technology, are deployed on Angel Island and San Francisco Bay Ferry vessels. These cameras continuously monitor whale activity, complementing human observations recorded through a public app. According to Daniel Zitterbart, the chief scientist at WhaleSpotter, this collective surveillance approach enhances whale protection by increasing monitoring coverage.
While British Columbia also utilizes WhaleSpotter cameras, the current setup only includes land-based installations, limiting their whale detection range to approximately two nautical miles. Tracking marine mammals is crucial for understanding their migration paths and mitigating vessel strikes, an escalating issue in the region.
The Whale Safe app in San Francisco Bay connects stakeholders, including scientists, mariners, researchers, and the public, to monitor whale sightings collaboratively. Douglas McCauley, director of the Benioff Ocean Science Laboratory, emphasized the community-driven nature of this initiative as a valuable resource for public service.
In British Columbia, WhaleSpotter camera data is accessible to approved commercial mariners via the Ocean Wise whale report alert system for whale proximity notifications, excluding general public access. Thomas Hall from San Francisco Bay Ferry highlighted the potential of ferry-mounted cameras to study long-term whale behavior patterns, aiding in route adjustments to minimize interactions with marine life.
Advocating for wider adoption of whale monitoring technology, Zitterbart expressed interest in equipping B.C. Ferries with similar camera systems to safeguard whales, especially along humpback whale migration routes. Responding to concerns over whale strikes, B.C. Ferries is considering deploying detection devices on specific routes, starting with the northern corridor where a humpback whale fatality occurred recently.
As concerns mount over the impact of increased ship traffic and climate change on whale populations, collaborative conservation efforts are paramount. The Benioff Ocean Science Laboratory reported a rise in grey whale sightings in San Francisco Bay, attributing some deaths to ship strikes. Conservation biologist Sean Brillant emphasized the urgency of addressing vessel strikes as a global issue, stressing the necessity of cross-border cooperation and data sharing to ensure whale safety.
Efforts to enhance whale protection through innovative technologies and community engagement are gaining momentum, aiming to mitigate the risks posed by maritime activities to marine mammals in both Californian and British Columbian waters.
