Ram Setu Seen from Space: European Space Agency Shares Stunning Image
The European Space Agency (ESA) has released a breathtaking image of the Ram Setu, also known as Adam’s Bridge, captured by its Copernicus Sentinel-2 satellite. This natural chain of limestone shoals connects India and Sri Lanka, spanning 48 km between Rameswaram Island in India and Mannar Island in Sri Lanka. The image showcases the intricate structure of the bridge, which separates the Gulf of Mannar from the Palk Strait.
Formation and Historical Significance
Numerous theories exist regarding the formation of Ram Setu. However, geological evidence suggests that the limestone shoals are remnants of land that once connected the two countries. Historical records indicate that this natural bridge was traversable until the 15th century, after which it gradually eroded due to storms.
Geographic and Environmental Insights
- Location: Ram Setu stretches from Rameswaram Island in India to Mannar Island in Sri Lanka.
- Depth: The sea in this area is very shallow, ranging from 1 to 10 meters deep, as indicated by the light color of the water in the satellite image.
- Connectivity:
- Mannar Island: Covers around 130 square kilometers, connected to mainland Sri Lanka by both a road and a railway bridge.
- Rameswaram Island (Pamban Island): Connected to the Indian mainland via the 2-km-long Pamban Bridge. The island’s main towns are Pamban and Rameswaram.
Biodiversity and Conservation
Both sections of Adam’s Bridge are part of protected national parks in their respective countries. The area is a crucial breeding ground for various species:
- Birds: Such as the brown noddy.
- Marine Life: Including dolphins, dugongs, and turtles.
- Flora: Numerous species of fish and seagrasses thrive in the shallow waters.
The European Space Agency’s Contribution
The ESA’s image highlights the dry sandbanks and shallow waters of Ram Setu, providing valuable insights into this unique geological and ecological region. The photograph not only emphasizes the natural beauty of the bridge but also underscores its historical and environmental significance.
