Others, too, see the value of working with industry groups. Whale safe Traveling through ports around Los Angeles as they help to avoid hitting large ships is an initiative from the University of California Santa Barbara. According to Douglas McCauley, professor of ocean science at UCSB, the program came as a response to seeking help from shipping companies.
Ship strikes, as they are known, are among the leading causes of death for whales, and 2018 and 2019 were the worst years on record for collisions on the West Coast, with a total of 27 deaths, according to National Oceanic and Atmospheric Regime. Management. Scientists estimate that the actual number of whales killed by ships may be much higher – According to a study, more than 80 people from the West Coast every year – Because not all corpses have been discovered.
Dr. McCauley helped bring ocean technologists working at UCSB to build a real-time detection system for whales in the Santa Barbara Channel, Combination of three inputs: An artificial intelligence algorithm that analyzes whale sounds, classifies them by species, and sends the data for review; A remote sensing system that predicts the presence of whales in the future; And plain old citizen science, where trained whale watchers log whales into a mobile app.
“It is not useful if you are only able to say, ‘Southern California is forecast to be cloudy with blue whale opportunity,” and this model predicts a much better scale, Drs. McCauley said.
The system distributes information to vessels in simplified rubrics of low, medium, high and very high, so that they can slow down when whales are around, which can Significantly reduces the number of ship attacks. Whale Safe only provides data about this particular stretch of the California coast, but Drs. McCauley said they were planning to expand to San Francisco and possibly elsewhere in North America.
When ships reduce their speed they use less fuel, resulting in lower greenhouse gas emissions and other pollutants; Accounts for the global shipping industry About 3 percent of global greenhouse gas emissions.
