Enhanced abundance of tintinnids under elevated CO2 level from coastal Bay of Bengal
Biswas, H.; Gadi, S.D.; Venkataramana, V.; Bharathi, M.D.; Priyan, R.K.; Manjari, D.T.; DileepKumar, M. (Springer, 2012)The role of microzooplankton (MZP) in the pelagic trophodynamics is highly significant, but the responses of marine MZP to increasing CO2 levels are rather poorly understood. Hence the present study was undertaken to ... -
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 atmospheric and physical forcings on biogeochemical cycling of dissolved oxygen and nutrients in the coastal Bay of Bengal
Sarma, V.V.S.S.; Sridevi, B.; Maneesha, K.; Sridevi, T.; Naidu, S.A.; Prasad, V.R.; Venkataramana, V.; Acharya, T.; Bharati, M.D.; Subbaiah, C.V.; Kiran, B.S.; Reddy, N.P.C.; Sarma, V.V.; Sadhuram, Y.; Murty, T.V.R. (Springer, 2013)Time-series observations were conducted off Visakhapatnam, central west coast of Bay of Bengal, from October 2007 to April 2009 to examine the influence of physical and atmospheric processes on water column nutrients ... -
Impact of river discharge on distribution of zooplankton biomass, community structure and food web dynamics in the Western coastal Bay of Bengal
Venkataramana, V.; Sarma, V.V.S.S.; Reddy, A.M. (Elsevier, 2017)Observations were carried out along the western coastal Bay of Bengal, to examine the physical, chemical and biological parameters during the summer monsoon particularly when the rivers of India are in flood condition and ... -
Influence of river discharge on abundance and composition of phytoplankton in the western coastal Bay of Bengal during peak discharge period
Bharathi, M.D.; Sarma, V.V.S.S.; Ramaneswari, K.; Venkataramana, V. (Elsevier, 2018)To understand the influence of river discharge on phytoplankton composition along western coastal Bay of Bengal (BoB), surface water samples were collected during peak discharge period. River discharge from the Ganges ... -
Magnitude of river discharge determines the food habit and community composition of zooplankton in the Indian estuaries during monsoon
Venkataramana, V.; Sarma, V.V.S.S.; Gawade, L.; Reddy, A.M. (Elsevier, 2021)Zooplankton of seventeen Indian estuaries were investigated using plankton net (200- mu M mesh; 0.25 m2 mouth area) during the peak discharge period of 2011. Results showed that the seventeen estuaries are comparable in ... -
Phytoplankton community structure is governed by salinity gradient and nutrient composition in the tropical estuarine system
Bharathi, M.D.; Venkataramana, V.; Sarma, V.V.S.S. (Elsevier, 2022)Primary production in the estuarine ecosystems is principally represented by phytoplankton. The presence or function of phytoplankton in estuarine production is mainly regulated by factors such as salinity, light, turbidity, ... -
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 ... -
River discharge as a major driving force on spatial and temporal variations in zooplankton biomass and community structure in the Godavari estuary India
Venkataramana, V.; Sarma, V.V.S.S.; Reddy, A.M. (Springer, 2017)Variability in horizontal zooplankton biomass distribution was investigated over 13 months in the Godavari estuary, along with physical (river discharge, temperature, salinity), chemical (nutrients, particulate organic ... -
Role of salinity on zooplankton assemblages in the tropical Indian estuaries during post monsoon
Venkataramana, V.; Gawade, L.; Bharathi, M.D.; Sarma, V.V.S.S. (Elsevier, 2023)The estuary is the transition zone between the riverine and marine environments, in which the zooplankton act as a trophic connector in the energy transfers from primary producers to secondary consumers. Zooplankton biovolume ...
