4 more whales wash up dead across the Sheland Islands, Scotland

13.10.18 Dead Whales In Shetland Islands, Scotland

Scientists have suggested that the deaths could be related to military activity in the Atlantic or oil and gas exploration work.

Three northern bottlenose whales have been found in Setter/Burra, Roe Sound/Muckle Roe and Fetlar with a sperm whale washed up in Mangaster, all in Shetland.

All these animals have been dead for a couple of weeks.

Karen Hall, of the local Scottish Natural Heritage office, said: “This is unusual for beached whales in Shetland to have so many in such a short space of time.

“The mass strandings in Scotland and Ireland over the last couple of months are the biggest numbers of Cuvier beaked whales so far in the world which is fairly serious.”

There have also been reports of a couple of Cuvier beaked whales washed up on the shore of Orkney and the Faroe Islands in the last month, while the Icelandic government is currently investigating the cause of the deaths of 12 northern bottlenose whales and three Cuvier beaked whales washed up off the country in July and September.

The Scottish Marine Animal Stranding Scheme (SMASS) have taken samples from the whales to test for pollutants and disease.

Ms Hall added: “If the cause of death was pollutants then other species of sea life would be washed up in mass and you would expect to see whales washed up in different degrees of decomposition.

“These animals died in a relatively quick period of time far out at sea which doesn’t fit the patterns of disease related deaths and subsequent decomposition.

“These are more likely to be noise related deaths. Deep sea whales swim up to one kilometre in depth in the ocean and when forced to the surface too quickly in fright from a massive sonar disturbance experience decompression sickness or the bends similar to that of human divers.”

Marine experts are suggesting the alarmingly high number of whale deaths may be related to sonar testing from foreign or UK military in the Eastern Atlantic to detect submarines.

Another possible cause may be the impact seismic surveys from deep sea oil and gas exploration has on whales due to loud blasts of compressed air being projected from seismic airguns through the deep sea water to reveal buried oil and gas deposits.
