Scientists from the ISRO have created the most precise undersea map yet of Adam’s Bridge widely known as the Ram Setu, proving the submerged ridge as a “continuity” from Dhanushkodi in India to Talaimannar in Sri Lanka.

As per the reports, the research is the first to provide precise details about the underwater sections of Adam’s Bridge.

The submerged structure was named Adam’s Bridge by an East India Company mapper. The structure, called by Indians as Ram Setu, is mentioned in the Ramayana as a bridge constructed by Ram’s army in order to help him reach Sri Lanka, Ravana’s kingdom, to get back his wife Goddess Sita.

Findings:

According to their findings, the ridge is around 8 meters above the seabed over most of its length. However, only around 0.02 percent of the volume is accessible or visible; the rest is submerged.

Their research also discovered 11 narrow passages, only a few meters wide, that allow water to flow or be exchanged between the Gulf of Mannar on the southwest side and the Palk Strait on the northeast side of the hill.

The experts believe that these tiny channels, or gaps along the ridge’s axis, play an important function in shielding or conserving the structure from the force of wave action. The bridge is constantly exposed to the energy of high waves from both sides: the Gulf of Mannar and the Palk Strait.
