Floating device deployed off Chile to protect whales from ships
A device floating in the waters off the coast of southern Chile aims to collect data on nearby whales to protect them from passing ships.
The first electronics buoy was recently put out to sea in the Gulf of Corcovado, about 1,100 kilometers from the capital, Santiago.
The device is designed to listen to the sounds made by whales when they communicate with each other. Animals use sound to map their movements and hunt.
Sounds are processed by artificial intelligence computer systems powered by (AI) for the purpose of identifying the whereabouts of animals. This information is then sent to marine operators to help them avoid crashing into the whales.
A non-profit organization called Blue Boat Initiative put the buoy in place. The group seeks to develop and deploy technological tools to provide an alert system to shipping companies. In addition to helping protect whales, the “smart” buoy also collects data on ocean health and the effects of climate change.
The group plans to place a series of buoys along the path the whales take on their journeys from Antarctica to the equator. The Gulf of Corcovado is rich in marine life, including large numbers of blue whales, as well as bowhead and southern right whales. All of these whales are listed as endangered under the Endangered Species Act. The region’s whale population is highest during the summer season in the southern hemisphere.
In 2008, Chile banned whaling activities, including whaling for scientific purposes. The country has established a number of protected areas for whales and other endangered species species.
“It’s the start of a longer road,” said Sonia Espanol, director of Blue Boat Initiative. She noted that her team plans to cover the gulf with at least six buoys. “The idea is to be able to cover the whole migration itinerary whales from Antarctica to the equator,” Espanol said.
The buoy operates using software called Listening to the Deep Ocean Environment (LIDO). The device permanently monitors sounds of the ocean. It uses AI to identify the type of whales and where they are in real time. It then sends messages to nearby ships so they can reduce noise levels and try to avoid accidents.
The buoys also contain sensors to measure water temperature, oxygen levels and more to predict ocean health and the effects of climate change. This information should be used to help guide public environmental policies.
In the United States, scientists have recently deployed a similar whale alert system off the US West Coast. This system, called Whale Safe, also uses buoys to identify the presence of whales.
