Adam's Bridge, also referred to as Rama's Bridge or Rama Setu, is a remarkable chain of limestone shoals connecting Pamban Island in Tamil Nadu, India, to Mannar Island in Sri Lanka. This natural formation has garnered significant attention due to its historical and geological importance.
Geological studies indicate that Adam's Bridge was once a land connection between India and Sri Lanka. Historical records suggest that the bridge was passable on foot until the 15th century. A severe cyclone in 1480 is believed to have deepened the channel, making it impassable.
The bridge spans approximately 50 kilometers, acting as a natural barrier separating the Gulf of Mannar from the Palk Strait. The region is characterized by shallow waters, with depths ranging from 1 to 10 meters. These shallow depths pose significant challenges for navigation.
Recent advancements in satellite imaging have provided new insights into Adam's Bridge. The European Space Agency's Copernicus Sentinel-2 mission has captured high-resolution images that showcase the remnants of the bridge. These images depict its current state, which consists of various small islands and sandbanks.
The data provided by the European Space Agency through the Copernicus Sentinel-2 mission is invaluable for scientific research and environmental monitoring. These high-resolution images allow researchers to study the geological features of Adam's Bridge and its surrounding environment.
