The Government of India has set up the two Coastal Research Vessels [CRVs] named Sagar Purvi and Sagar Pashchimi. Sagar Purvi studies about ocean parameters along the coastal waters of India. The data and samples collected using CRV Sagar Purvi were useful in understanding the marine pollution levels, biological wealth and conservation of seaside resources in the coastal waters of India and for the better understanding of the seabed morphological topographies and its geo-morphological implications.
