• Adam’s Bridge, also known as Rama’s Bridge or Rama Setu, is a chain of limestone shoals connecting Pamban Island in Tamil Nadu, India, and Mannar Island in Sri Lanka.
Historical Significance:
• Geological evidence indicates it was once a land connection between India and Sri Lanka. Historical records suggest it was passable on foot until the 15th century when a cyclone deepened the channel in 1480.
Geographical Details:
• The bridge spans 50 km and separates the Gulf of Mannar from the Palk Strait. The area is characterized by shallow seas, with depths ranging from 1 to 10 meters, which hinders navigation.
Recent Developments:
• Recent satellite images by the European Space Agency’s Copernicus Sentinel-2 mission highlight the remnants of the bridge. These images show the bridge’s current form, consisting of small islands and sandbanks.
Significance of Satellite Data:
• The European Space Agency provides high-resolution images through the Copernicus Sentinel-2 mission, offering valuable data for scientific research and environmental monitoring.
