  • The International Seabed Authority (ISA) is taking permit applications in July from companies that want to mine the ocean’s floor.
  • The undersea mining will be conducted to extract key battery materials — cobalt, copper, nickel, and manganese.
  • They are in the form of potato-sized rocks called “polymetallic nodules”.
  • They are found at depths of 4 kilometers to 6 kilometers (about 2.5 miles to 3.7 miles).
  • The Jamaica-based ISA was established under the UN Convention on the Law of the Sea.
  • It holds authority over the ocean floors outside of its 167 member states’ Exclusive Economic Zones.
