They help not to harm neither to mammals, nor to rescuers.
In the US, whale rescuers use drones to free entangled animals. According to rescue coordinator Ed Lyman, animals often get serious injuries or die from networks.
However, whales are no less dangerous for those who want to release them. In the summer of 2017, one of the rescuers died, trying to rescue the whale from the network. In order to save whales has become safer for both humans and animals, it has been decided to use drones.
People often ask: do the whales understand that you want to help them. And in fact, we can not so presume. These whales are large animals. It’s about 13-meter animals weighing 40 tons, and to release them is not an easy task.
Drones allow rescuers to view the whale from a height, to understand what adaptations they need and how they should act better with the entangled animal. When the rescuers swim to the whale, they can only release it.
The US National Oceanic and Atmospheric Administration receives drones from the non-profit organization Oceans unmanned. Its goal was to use technologies that would reduce people’s interference in protecting the oceans.
Running drones from lifeboats or smaller boats, we can better see the whales and understand what is happening [with them] with less risk for both rescuers and whales.
