Carlsberg Ridge

Recently, the Indian government signed a contract with the International Seabed Authority to explore polymetallic sulphur nodules in the Carlsberg Ridge.

About Carlsberg Ridge

The Carlsberg Ridge is a mid-oceanic ridge located in the Indian Ocean. It is a divergent plate boundary, where tectonic plates are moving apart.

Location: It extends from the triple junction of the African, Indian, and Australian tectonic plates, which is where it connects with the Mid-Indian Ridge. It runs northwest toward the Gulf of Aden.
Geographic Separation: The ridge separates the Arabian Sea to the northeast from the Somali Basin to the southwest.
Tectonic Boundary: It marks the boundary between the Somali Plate and the Indian Plate.
Depth: The ridge has a mean depth between 6,000 to 12,000 feet (1,800 to 3,600 meters) below the sea surface, though some areas of the ridge rise to a mean elevation of about 7,000 feet (2,100 meters) above the seafloor.
Geological Significance: The Carlsberg Ridge is the most prominent mid-ocean ridge segment in the western Indian Ocean and contains numerous earthquake epicenters.
Connection with Other Geological Features: It turns westward around the island of Socotra and eventually links to the East African Rift System through the Gulf of Aden.

Polymetallic Sulphur Nodules

The exploration of polymetallic sulphur nodules in the Carlsberg Ridge is a significant development. These nodules are rich in precious metals such as nickel, copper, and cobalt, which are essential for various high-tech applications, including electric vehicle batteries and renewable energy systems.

The International Seabed Authority (ISA) governs the exploration and exploitation of these seabed resources in international waters. This agreement will enable India to explore these valuable mineral resources in the Indian Ocean.
