Editorial 1: The Indian Ocean Mineral Exploration Push
Context:
India has emerged as a key player in deep-sea mineral exploration, becoming the first country to secure two contracts with the International Seabed Authority (ISA) for exploring polymetallic sulphides (PMS) in the Indian Ocean. These resources—rich in copper, nickel, cobalt, and rare earth elements—are vital for renewable energy technologies, green infrastructure, and advanced electronics, making the initiative geopolitically and strategically significant.
Formation of Poly-metallic Nodules:
- Polymetallic sulphides are mineral-rich deposits formed around hydrothermal vents on the ocean floor.
- These vents, where superheated water interacts with volcanic rocks, result in chimney-like structures containing high concentrations of valuable metals such as copper, gold, silver, zinc, and cobalt.
- These metals are in great demand due to their role in battery manufacturing, electric vehicles, solar panels, wind turbines, and electronics—critical sectors in the transition towards cleaner energy.
- While countries like China, South Korea, and Russia have already secured ISA contracts, India’s exploration is unique because it now holds rights in two separate regions, giving it a broader scope for resource identification.
India’s contracts with ISA:
- India’s first contract with the ISA dates back to 2016, when it was granted rights to explore 10,000 sq km of the Central Indian Ocean Ridge (CIR) for PMS deposits.
- Recently, it secured a second contract for 2,239 sq km in the Carlsberg Ridge (CR), located near the Lakshadweep islands. With these, India has become the first country to manage two exploration zones for PMS.
- The Carlsberg Ridge is a tectonically active region stretching between the Arabian and Somali basins. It is rich in hydrothermal vent fields and is believed to host abundant PMS deposits.
- The proximity of the CR zone to India enhances its strategic value, ensuring access to resources close to the country’s maritime boundaries.
Significance of these contracts:
- Resource Security: With global demand for metals like cobalt and nickel skyrocketing due to the push for green technologies, having early access to oceanic deposits ensures India does not remain dependent on volatile foreign supply chains.
- Geopolitical Leverage: Securing rights in the Indian Ocean enhances India’s strategic footprint in the region. Given increasing Chinese presence in deep-sea exploration, India’s contracts strengthen its claim as a leading player in maritime resource management.
- Scientific Advancement: These projects also push India’s research capabilities in oceanography, deep-sea mining technologies, and geology, areas in which the country is building expertise through institutions like the National Institute of Ocean Technology (NIOT) in Chennai.
- Blue Economy: The initiative aligns with India’s Deep Ocean Mission and its broader vision of developing a sustainable “blue economy,” using marine resources for economic growth without harming ecosystems.
Challenges ahead:
- Despite the optimism, deep-sea exploration comes with several challenges:
- Extracting minerals at depths of 3,000–6,000 meters requires highly advanced remotely operated vehicles, robotics, and pressure-resistant equipment. India is still developing many of these systems.
- Mining hydrothermal vents can devastate fragile deep-sea ecosystems, many of which host unique species not found elsewhere. The ecological impact of large-scale extraction remains poorly understood. Balancing mineral needs with sustainability will be crucial.
- Deep-sea mining is capital-intensive. The costs of exploration, extraction, and processing may outweigh benefits if global prices for metals fluctuate.
India’s Deep Sea Mission:
- India’s contracts are valid for 15 years each, during which it must conduct detailed surveys, assess commercial viability, and submit environmental impact studies to the ISA. Only after completing this phase can extraction is considered.
- To strengthen its deep-sea program, India is investing heavily in the Deep Ocean Mission, launched in 2021. The mission includes developing technologies for mining polymetallic nodules and sulphides, creating manned submersibles capable of 6,000-metre dives, and establishing on-shore processing plants.
- India is also expected to work with international collaborators to refine mining technology and environmental safeguards.
- If executed responsibly, these efforts could place India at the forefront of sustainable deep-sea mining, ensuring both strategic autonomy and ecological balance.
Way Forward:
India’s twin contracts for PMS exploration in the Central Indian Ocean Ridge and Carlsberg Ridge mark a milestone in its maritime ambitions. They strengthen resource security, scientific capacity, and strategic influence in the Indian Ocean. However, realizing these benefits requires overcoming technological, ecological, and economic challenges.
