CSIR-NIO will undertake a three-year scientific project. “The idea is to see whether Ram Setu is a man-made structure or not. The most important aspect of the project is to establish its age, scientifically. 

Details

• Indian scientists will undertake a scientific expedition to date the chain of corals and sediments forming the Ram Setu.
• Also known as Adam’s bridge, this 48-km long bridge-like structure between India and Sri Lanka finds mention in the Ramayana but little about its formation is known or proven, scientifically.

How is the project planned?

• The project is expected to formally commence by the end of March. An initial survey will make use of underwater photographs to check if any habitation remains inundated in the area. A geophysical survey will be performed to understand the structure.
• “Over the years, several kinds of depositions, including sand, have covered the actual structure. Initially, only physical observation, and no drilling, will be done. A scientific survey will be performed to understand the sub-surface structure.
