Reduzieren Sie Angriffe von Walschiffen, indem Sie 2,6 % der Meeresoberfläche sicherer machen, heißt es in einer Studie | Forscher identifizieren weltweit Kollisionsschwerpunkte, stellen jedoch fest, dass es in fast allen Fällen an Präventionsmaßnahmen mangelt

From the article: Collisions between whales and ships can prove fatal for the marine mammals, but researchers say expanding mitigation measures to just 2.6% of the ocean’s surface would reduce the chance of such strikes in all risk hotspots.

While experts say many whale-ship collisions go unobserved and unreported, making it difficult to put a figure on the scale of the problem, some estimates suggest tens of thousands of the animals are killed each year.

Now researchers say they have not only identified hotspots where the risk of collisions is greatest, but revealed almost all of these lack measures to mitigate such strikes.

Dr Jennifer Jackson, of the British Antarctic Survey and a co-author of the research, said: “This is the first study to look at this problem at a global scale, enabling global patterns of collision risk to be identified using an extremely large contemporary dataset of four recovering whale species.”

Writing in the [journal Science](https://www.science.org/doi/10.1126/science.adp1950), the team report how they compiled a dataset of 435,000 whale locations, recorded between 1960 to 2020, for blue, fin, humpback and sperm whales.
