Algal blooms: a perspective from the coasts of India
TL;DR: A review of bloom occurrences in Indian waters from 1908 to 2009 points out that a total of 101 cases have been reported as discussed by the authors, of which 39 causative species responsible for blooms, of which Noctiluca scintillans and Trichodesmium erythraeum are the most common.
Journal ArticleDOI
Primary description of surface water phytoplankton pigment patterns in the Bay of Bengal
TL;DR: In this article, the spatial and temporal variations in surface water phytoplankton pigment distribution in the Bay of Bengal were studied during the spring intermonsoon (SpIM, February-April) and the commencement of the summer monsoon (CSM, May-June), using pigment and diagnostic indices.
Journal ArticleDOI
Dinoflagellate community structure from the stratified environment of the Bay of Bengal, with special emphasis on harmful algal bloom species
TL;DR: The presence of frequently occurring HAB species in low abundance in stratified waters of the BOB may not be a growth issue, however, they may play a significant role in the development of pelagic seed banks, which can serve as inocula for blooms if coupled with local physical processes like eddies and cyclones.

TL;DR: From the present study, it is evident that the flagellate group is the ideal one to survive in such a complex regime, however, the observed small interval oscillation in the phytoplankton community could be a coupled effect of bottom-up (vertical advection that alters the nutrient flux), and top-down (increased abundance of microzooplankton) factors.
Journal ArticleDOI
Phytoplankton biomass and primary production in Delagoa Bight Mozambique: Application of remote sensing
TL;DR: A non-linear model that uses satellite-derived chlorophyll to estimate water-column primary production was developed and tested using data from the Delagoa Bight, where the model results compared well with local estimates as discussed by the authors.
