![]() Though deep sea mining companies have not yet received permission to start mining commercially, they are asking governments for the green light for the first time this July. So far 17 exploratory deep sea mining contracts have been granted in this part of the Pacific Ocean. ![]() However, mining companies are interested in extracting metals and minerals from the seafloor in this area, which is believed to be rich in valuable materials. However, scientists say the impact on cetaceans and other large animals that may face harm from sound pollution needs to be urgently assessed before permission for commercial mining is given.ĭolphins and sperm whales are among the 25 cetacean species found in the Clarion-Clipperton Zone (CCZ) between Mexico and Hawaii in the Pacific Ocean, according to the paper. Until now, assessments of impacts from mining have focused on seabed species, as this is the direct area mined. The research concludes that the constant disturbance could cause ill health. It’s no different for whales or dolphins,” said Dr Kirsten Thompson, of the University of Exeter. Your mental health would be compromised, you might change your behaviour to escape from it. “Imagine if your neighbourhood was suddenly disrupted by construction work that goes on 24/7, your life would change dramatically. ![]() Scientists said the disturbance would be constant for the marine mammals, similar to noisy construction work in a human neighbourhood that was impossible to escape from. The research, published in Frontiers in Marine Science, finds that noise pollution in particular could cause damage to the sensitive, intelligent animals.
