An AI-powered whale detection network, WhaleSpotter, has been launched in San Francisco Bay this week, designed to allow ferries, cargo ships, and tankers to continue operations while mitigating the visible consequences of their presence. The system scans for whale blows and heat signatures, alerting mariners in real time to enable ships to slow down or reroute. This technological intervention arrives as the bay experiences a severe rise in gray whale deaths, with 21 dead gray whales found last year in the wider Bay Area—the highest number in 25 years. At least 40% of these deaths were attributed to ship strikes, a direct externality of commercial maritime traffic. Scientists report that at least 10 more whales have died in the Bay Area so far this year, noting that these figures likely underestimate the true toll due to carcasses sinking or being swept out to sea.
Capital's Contradictions and Ecological Costs
The increasing presence of whales in the bay, directly overlapping with established shipping lanes and ferry routes, is a symptom of broader systemic failures. Gray whales, undertaking a 12,000-mile migration, are now diverting into San Francisco Bay and lingering for days or weeks. Scientists increasingly link this shift to climate change, a direct consequence of unchecked industrial capital and fossil fuel extraction. A 2023 study in Science revealed that warming temperatures and shifts in Arctic sea ice are disrupting the food web gray whales rely on, leaving many malnourished during their arduous migration. These vulnerable whales are concentrating in a high-traffic corridor between Angel Island, Alcatraz, and Treasure Island, a location Rachel Rhodes, a project scientist at the Benioff Ocean Science Laboratory, described as “the worst place possible in terms of all the ship traffic.” The scale of the problem is such that "the teams responding to strandings said they ran out of places to even land dead whales."
The Eastern North Pacific gray whale population, once hailed as a conservation success after being removed from the Endangered Species Act 32 years ago, has seen its numbers plummet by half over the last 10 years, according to the National Oceanic and Atmospheric Administration. Only 13,000 remain. Rhodes noted that whales "may not be getting the quality or quantity of food they’re used to in the Arctic," forcing them to start their long migration "at a disadvantage."
The State's Management of Capital's Externalities
The WhaleSpotter system, while presented as a solution, functions primarily to manage the contradictions between capital accumulation through shipping and the ecological devastation it produces. Thomas Hall, director of operations for San Francisco Bay Ferry, stated that mariners "will be able to make adjustments way before they get anywhere close," and that the system "will also allow us to track data over time and see where the whales are camping out so we can adjust our routes during whale season to avoid those areas completely.” This approach prioritizes minor operational adjustments over fundamental changes to shipping volumes or routes. The system integrates land-based and vessel-mounted detections, relaying sightings in near real time, ensuring the smooth flow of commercial traffic can continue with reduced public scrutiny over whale deaths. Douglas McCauley, director of the Benioff lab, acknowledged the "flood of detections" and being "a little bit on edge," yet affirmed the intent to "use that data and we’re going to be smart about how we use that space and share it with the whales," implying continued shared use rather than a re-evaluation of the space's primary function for capital.
Beyond shipping, a severe marine heat wave off the California coast, another consequence of the climate crisis, is shrinking nutrient-rich waters, pushing humpback whales closer to shore. Here, they encounter the Dungeness crab fishery, a commercial enterprise utilizing tens of thousands of vertical lines that create entanglement hazards. Kathi George, director of cetacean conservation biology at The Marine Mammal Center, explained that “Humpbacks are curious and they’ll scratch their backs on the gear,” adding, “If they get a line caught on their body, they’ll breach and they’ll roll and end up entangling themselves.” Whales can drag heavy gear for months, unable to dive or feed properly, leading to starvation, infection and drowning. Thirty-six whales were confirmed entangled off the West Coast in 2024, the highest number since 2018, according to NOAA, though scientists caution most cases go undocumented.
In response, regulators this spring again closed parts of the fishery off central California to conventional gear, a measure that has become increasingly common. This state intervention manages the conflict by imposing temporary restrictions on one sector of capital (fishery) to mitigate harm, while simultaneously approving new technologies to allow harvesting to continue. California approved commercial use of ropeless pop-up crab fishing gear this spring, allowing fishermen to continue harvesting through the end of the season. Supporters claim this technology reduces risk to whales, effectively preserving the commercial activity. Caitlynn Birch, Oceana’s Pacific campaign manager, articulated the liberal approach, stating, “We will have to continue to be adaptive and science driven in terms of our management to reduce wildlife risk and keep fishermen on the water.” This perspective frames the ongoing ecological crisis as a management problem within the existing economic framework, rather than a fundamental indictment of the system driving both climate change and the relentless pursuit of profit in shared natural resources.
