Positioning waves cause whales to die in mass

When about 100 whales strayed into the shallow waters of Loza of Madagascar in May and June 2008, scientists suspected that underwater positioning waves played a role in this.

A group of independent scientists recently confirmed the relationship between underwater positioning waves, used by Exxon Mobil Corporation to map ocean beds for oil, with the death of ¾ of the early whales. lost.

When marine animals enter areas that they do not normally visit, such as shallow waters, it is the act of getting aground, dead or alive.

This is not the first study to confirm the link between locating waves and the state of stranded whales.

When about 150 head whales were washed into Hanalei Bay at Kaua'i Island in Hawaii in 2004, the US National Oceanic and Atmospheric Administration (NOAA) connected the event to the ship's wave underground of the US Navy.

NOAA's Southwest Fisheries Science Center in Pacific Grove, California, said it's unclear exactly why the whale changes behavior, but its organization expert Robert Brownel assumes that the sound of the wave "set up the sound wall, make them want to run away" , according to CBS News.

Others blame the lunar cycle, which triggers a runoff, based on 21 similar events, according to AFP.

However, with the new conclusion in Madagascar, human impact has clearly affected the normal activities of marine animals.
