Why in the News?
- The study, conducted by Britain’s National Oceanography Centre, found long-term sediment changes and a decline in populations of larger organisms in the mined area.
- This comes amid growing global calls for a moratorium on deep sea mining, with 36 countries recently discussing the issue at a United Nations International Seabed Authority meeting in Jamaica.
What is Deep Sea Mining?
Deep sea mining involves the extraction of mineral deposits and metals from the ocean seabed. It is categorized into three types:
|
Type of Deep Sea Mining
|
Process
|
Key Minerals Extracted
|
|
Polymetallic Nodule Mining
|
Collecting mineral-rich nodules from the ocean floor
|
Nickel, Cobalt, Rare Earths
|
|
Seafloor Massive Sulphide Mining
|
Extracting metal deposits from hydrothermal vents
|
Gold, Silver, Copper, Zinc
|
|
Cobalt-Rich Crust Mining
|
Stripping cobalt crusts from underwater mountains
|
Cobalt, Platinum, Manganese
|
- These minerals are crucial for battery production, renewable energy technologies, and electronics like mobile phones and computers.
- Mining technology is still evolving, with companies developing:
- Massive pumps to vacuum materials from the seabed
- AI-based deep-sea robots to extract nodules
- Advanced machinery for mining near underwater mountains and volcanoes
- Governments and corporations view deep sea mining as a strategic necessity due to depleting onshore reserves and increasing demand for critical minerals.
International Seabed Authority (ISA)
About ISA
- Established under the 1982 United Nations Convention on the Law of the Sea (UNCLOS).
- Came into force in 1994 and became fully operational in 1996.
- Headquarters – Kingston, Jamaica.
Functions of ISA
- Regulates and manages mineral-related activities in international seabed areas beyond national jurisdiction.
- Grants licenses for deep-sea exploration and mining.
- Ensures environmental protection while overseeing resource utilization.
- ISA recently held a council meeting with 36 countries to discuss whether mining companies should be allowed to extract minerals from the ocean floor.
