Enhanced chlorophyll a and primary production in the northern Arabian Sea during the spring intermonsoon due to green Noctiluca scintillans bloom
Madhu, N.V.; Jyothibabu, R.; Maheswaran, P.A.; Jayaraj, K.A.; Achuthankutty, C.T. (Taylor & Francis, 2012)The surface waters of the northeastern Arabian Sea sustained relatively high chlorophyll a (average 0.81+ or -0.80 mg m sup(-3)) and primary production (average 29.5+ or -23.6 mgC m sup(-3)d sup(-1)) during the early spring ... -
Environmentally-related seasonal variation in symbiotic associations of heterotrophic dinoflagellates with cyanobacteria in the western Bay of Bengal
Jyothibabu, R.; Madhu, N.V.; Maheswaran, P.A.; Devi, C.R.A.; Balasubramanian, T.; Nair, K.K.C.; Achuthankutty, C.T. (Balaban Publishers, 2006)In the western Bay of Bengal, some species of heterotrophic dinoflagellates recurrently show symbiotic associations with cyanobacteria (Synechococcus/Synechocystis). The occurrence of these associations is markedly higher ... -
