Sediments in Palk Strait Between Gulf of Mannar and Bay of Bengal, India and Sri Lanka10.0N 79.7E
Greenish sediments are present in the Palk Strait, between the Tamil Nadu state of India and the northernmost part of the island nation of Sri Lanka. The strait connects the Bay of Bengal in the northeast with the Gulf of Mannar in the southwest.
The sediments come from rivers such as the Vaigai River of Tamil Nadu. A chain of low islands and reef shoals at the south end, collectively called Adam’s Bridge, extendsbetween Dhanushkodi on Pamban Island (also known as Rameswaram Island) in Tamil Nadu and Mannar Island in Sri Lanka. This chain limits the sediments passing into the Gulf of Mannar.
