Abstract

Reddish discoloration of coastal waters along the east coast of India at latitude 19.3 was observed during April 2014. Phytoplankton analysis revealed presence of Red Noctiluca scintillans cells in the water samples. A technique of detecting green Noctiluca scintillans was developed earlier, which is based on the principle of recognition of spectral shapes remote sensing reflectance spectra for Aqua-MODIS bands. This was appropriately modified to detect red Noctiluca in the coastal waters of the bay of Bengal. Phytoplankton species images generated using the modified approach were validated using information on reported events of red and green Noctiluca in the coastal waters. In addition to this, the study reported here highlights two major developments. One is, the classified species image reveals co-existence of diatom, red and green Noctiluca in coastal waters of the east coast and the second, it has been demonstrated with satellite time-series images that red Noctiluca succeeds diatom
