- India's Deep Sea Mission discovered of an active hydrothermal vent 4,500 metres below the surface of the Indian Ocean.
- The NIOT and the NCPOR captured the first image of an active hydrothermal vent located 4,500 metres below.
- Hydrothermal vents are like hot springs on the ocean floor.
- They form along mid-ocean ridges where tectonic plates move apart.
- The magma from the Earth's mantle rises to fill the gap and cools to form new crust and volcanic mountain chains.
- When seawater seeps into the cracks in the crust, it gets heated by this magma and shoots back out, carrying dissolved minerals.
- As the hot water meets the cold seawater, these minerals solidify, creating the chimney-like structures around the vents.
- The first hydrothermal vent was discovered in 1977 on the Galapagos Rift in the eastern Pacific Ocean.
