Predatory whales turn over ships and kill people. How to stop it?

Predatory whales, which are also known as killer whales,often at high speed they collide with boats and turn them over. One of these cases occurred in September 2018, 50 kilometers from Magadan - the collision of several orcas with a motor boat caused the death of one fisherman. Soon this problem will be partly solved thanks to the technology developed by researchers from the Oceanographic Institute at Woods Hole. They offer to detect the giant inhabitants of the oceans with the help of special cameras.

The most common killer whale collisions with shipsoccur near the islands of the Persian Gulf. In this region, the routes of ships and boats pass through narrow channels in which endangered killer whales live. During clashes, predatory whales are seriously injured, and passengers of the ships - severe injuries.

How do orcas kill people?

Researchers at the Oceanographic Institutebelieve that you can avoid such incidents, if you know the exact location of killer whales. As a tool for detecting animals, they suggest using so-called infrared cameras that capture the heat emitted during the breathing of killer whales. Since ships can also emit heat, the developers have equipped the cameras with artificial intelligence that knows the difference between them.

Infrared cameras at the ferry terminal

The system will be tested on the island of Galliano -infrared cameras are already installed at the ferry terminal to monitor the entrance to the kilometer-long strait. For one year, they will scan the territory round-the-clock for the presence of killer whales, and, if they are found, notify water transport operators. The island is already using an acoustic detection system, so infrared technology will complement it.

This work is only part of the overall solution.collision avoidance. But if the technology is sufficiently effective, we will be able to install infrared cameras right on the bow of ferry ships, ”shared Dan Citterbart, head of research.

Killer whales are not only dangerousships and their passengers, but also for deadly white sharks. After studying the data on the movement of 165 sharks marked with GPS sensors in the period 2006 to 2013, it turned out that when they see killer whales, white sharks immediately leave their hunting ground.
