Deep sea mining permits may be coming soon
Context
The International Seabed Authority (ISA) is preparing to resume negotiations that could open the international seabed for mining, including for materials critical for the green energy transition.
What is Deep Sea Mining?
- Deep sea mining involves removing mineral deposits and metals from the ocean’s seabed.
- Types: There are three types of such mining:
- taking deposit-rich polymetallic nodules off the ocean floor
- mining massive seafloor sulphide deposits
- stripping cobalt crusts from rock
- Utilisation: These nodules, sulphide deposits and crusts contain materials, such as nickel, rare earths, cobalt and more.
- They are needed for batteries and other materials used in tapping renewable energy and also for everyday technology like cellphones and computers.
- Technology used for deep sea mining:
- massive pumps
- artificial intelligence-based technology
- deep sea robots to pluck nodules from the floor
- advanced machines that could mine materials off side of huge underwater mountains and volcanoes

What are the Environmental Concerns?
- Damage to ecosystem: The ecosystems can be damaged by mining, especially without any environmental protocols.
- Damage from mining can include noise, vibration and light pollution, as well as possible leaks and spills of fuels and other chemicals used in the mining process.
- Threat to species: Sediment plumes from the some mining processes are a major concern. Once valuable materials are taken extracted, slurry sediment plumes are sometimes pumped back into the sea. That can harm filter feeding species like corals and sponges, and could smother or otherwise interfere with some creatures.
