US researchers have published a survey that badyzes for the first time the impact that the circulation of ships in the Arctic at the end of the summer generates in the marine mammal population. More specifically, the work published in PNAS examines the risk posed by cruises and other vessels in areas that previously had more ice in September and in many cases could not be crossed by commercial vessels. , developed by the Universities of Washington and Alaska Fairbanks, cites as an example the road that cruised through the Northwest Pbadage (which unites the Pacific and Arctic oceans) in August 2016, something that has not not been seen before.

The publication details that the narwhal, a cetceo known for his long defense on the front, is the most vulnerable species to these new seasonal routes, since he lives in small areas and in the middle of these roads. The work also mentions belugas and whales in Greenland, in addition to walrus, as species that are threatened by these factors.
The researchers suggest that with this information, mitigation plans can be developed in the Arctic to reduce the impact of the lack of ice on animal populations. It is proposed that mitigation strategies be developed to help vessels avoid critical habitats, adjust their movements for migration, and make efforts to minimize noise pollution.
