Contrasting phytoplankton community structure and associated light absorption characteristics of the western Bay of Bengal
Pandi, S.R.; Kiran, R.; Sarma, N.S.; Srikanth, A.S.; Sarma, V.V.S.S.; Krishna, M.S.; Bandyopadhyay, D.; Prasad, V.R.; Acharyya, T.; Reddy, K.G. (Springer, 2014)Absorption spectra, particulate pigments, and hydrochemical constituents were measured in the western Bay of Bengal (BoB) during July-August 2010 when influence of river discharge is at peak. Chromophoric dissolved organic ... -
High CO2 emissions from the tropical Godavari estuary (India) associated with monsoon river discharges
Sarma, V.V.S.S.; Kumar, N.A.; Prasad, V.R.; Venkataramana, V.; Appalanaidu, S.; Sridevi, B.; Kumar, B.S.K.; Bharati, M.D.; Subbaiah, C.V.; Acharyya, T.; Rao, G.D.; Viswanadham, R.; Gawade, L.; Manjary, D.T.; Kumar, P.P.; Rajeev, K.; Reddy, N.P.C.; Sarma, V.V.; Kumar, M.D.; Sadhuram, Y.; Murty, T.V.R. (American Geophysical Union, 2011)Estuaries have been under sampled to establish them as sources or sinks of the atmospheric carbon dioxide. Such poor coverage is well known for tropical, particularly monsoon driven, estuaries. In an attempt to study the ... -
Impact of salinity and pH on phytoplankton communities in a tropical freshwater system: An investigation with pigment analysis by HPLC
Chakraborty, P.; Acharyya, T.; Babu, P.V.R.; Bandyopadhyay, D. (The Royal Society of Chemistry, 2011)An in vitro study was carried out to understand the effects of salinity shock and variation in pH on phytoplankton communities in a tropical freshwater system of the Godavari River (a major peninsular river in India). The ... -
Influence of river discharge on plankton metabolic rates in the tropical monsoon driven Godavari estuary, India
Sarma, V.V.S.S.; Gupta, S.N.M.; Babu, P.V.R.; Acharyya, T.; Harikrishnachari, N.; Vishnuvardhan, K.; Rao, N.S.; Reddy, N.P.C.; Sarma, V.V.; Sadhuram, Y.; Murty, T.V.R.; Kumar, M.D. (Elsevier, 2009)To examine the influence of river discharge on plankton metabolic balance in a monsoon driven tropical estuary, daily variations in physico-chemical and nutrients characteristics were studied over a period of 15 months ... -
Intensified oxygen minimum zone on the western shelf of Bay of Bengal during summer monsoon: Influence of river discharge
Sarma, V.V.S.S.; Krishna, M.S.; Viswanadham, R.; Rao, G.D.; Rao, V.D.; Sridevi, B.; Kumar, B.S.K.; Prasad, V.R.; Subbaiah, Ch.V.; Acharyya, T.; Bandopadhyay, D. (Springer, 2013)A study on biogeochemical cycling in the west coastal Bay of Bengal was undertaken during the peak discharge period to understand the influence of enhanced stratification and primary production on the possible intensification ... -
Reduced river discharge intensifies phytoplankton bloom in Godavari estuary, India
Acharyya, T.; Sarma, V.V.S.S.; Sridevi, B.; Venkataramana, V.; Bharathi, M.D.; Naidu, S.A.; Kumar, B.S.K.; Prasad, V.R.; Bandyopadhyay, D.; Reddy, N.P.C.; DileepKumar, M. (Elsevier, 2012)Changes in river discharge alter material load and the consequent estuarine and coastal biogeochemical process. Evidence for biogeochemical response to variable rainfall over catchment area or changes in river discharges ... -
Status and conservation challenges of the second-largest seagrass bed in India: Chilika lagoon
Acharyya, T.; Raulo, S.; Singh, Sambit; Sudatta, B.P.; Srichandan, S.; Baliarsingh, S.K.; Samal, R.N.; Sahoo, C.K. (Springer, 2023)Studies related to seagrass ecology, conservation, and management are sparse and highly biased in India. Even though the geographical distribution of seagrass is diverse in India, about 74% of the scientific publications ... -
Stress and toxicity of biologically important transition metals (Co, Ni, Cu and Zn) on phytoplankton in a tropical freshwater system: An investigation with pigment analysis by HPLC
Chakraborty, P.; Babu, P.V.R.; Acharyya, T.; Bandyopadhyay, D. (Elsevier, 2010)Stress and toxicity of four biologically important transition metals (Co, Ni, Cu and Zn) on phytoplankton in Godavari River (a tropical freshwater system) were studied to understand the fate of phytoplankton of freshwater ... -
