Detection of submerged reef banks in the Lakshadweep Sea using IRS-P4 OCM satellite data

Abstract

The coral reef systems of the Lakshadweep region are unique from an ecological perspective. The region around Lakshadweep Islands is characterized by shallow submerged reef banks. This study demonstrates the use of IRS-P4 OCM satellite data in deciphering information about the extent of submerged reef banks in this area. The short wavelength OCM spectral bands have been found to be useful in detecting submerged reef banks as deep as 50–60 m below the ocean surface. This information is useful for updating navigational charts and to minimize ecological losses for the reefs of this region.
