under the sea

Earlier this week it was reported that the International Seabed Authority (ISA) closed its meeting without reaching agreement on regulations on deep-sea mining. In the absence of such regulation, uncontrolled mining could start at the end of June next year. Ahead of this development I looked into deep-sea mining again and at one particular problem that I hadn't covered in my previous features on the subject (2015, 2014), namely noise pollution. The feature is out now:

Polymetallic nodules found on the seafloor at depths between four and six kilometres are the target of planned seafloor mining operations. Formerly known as manganese nodules, they also contain cobalt, nickel, copper and rare earth metals. (Photo: James St. John/Flickr (CC BY 2.0).)
