Sediments in the Palk Strait and the Puttalam Lagoon, Sri Lanka8.0N 79.8E
Sediments turn the waters of the Palk Strait, between India (left) and Sri Lanka (right), green. On the other hand, the Gulf of Mannar, directly south of the strait, appears clear of sediments except for a small amount spilling forth from the Puttalam Lagoon on Sri Lanka’s west coast.
The Kalpitiya Peninsula partially separates the lagoon from the Gulf. The Puttalam district is well known for its picturesque lagoons, popular for shallow sea fishing and prawn farming activities.
