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 ...

A revisit to the regulation of oxygen minimum zone in the Bay of Bengal

Sridevi, B.; Sarma, V.V.S.S. (Springer, 2020)

Occurrence of intense oxygen minimum zone (OMZ) is known in the Bay of Bengal (BoB), but it has been recently reported to have become more acute and is at its tipping point. Here, we show that the intensification of OMZ ...

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 ...

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 ...

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 ...

Relations between marine biogeochemical indices and cloud properties over the Arabian Sea

Rao, V.D.; DileepKumar, M.; Sridevi, B.; Sarma, V.V.S.S. (Springer, 2021)

Knowledge of relations among ocean biogeochemical and cloud properties will help to plan experiments necessary to understand the mechanisms and processes underlying the links between ocean and atmosphere interactions. Here, ...

Role of river discharge and warming on ocean acidification and pCO2 levels in the Bay of Bengal

Sridevi, B.; Sarma, V.V.S.S. (Taylor and Francis, 2021)

Shifts in surface ocean pCO2 and pH are important controls governing global climate. Based on the linear relationship of observed surface pH and pCO2 with sea surface temperature (SST), sea surface salinity (SSS) and ...

Decadal variations in natural and anthropogenic aerosol optical depth over the Bay of Bengal: the influence of pollutants from Indo - Gangetic Plain

Yadav, K.; Rao, V.D.; Sridevi, B.; Sarma, V.V.S.S. (Springer, 2021)

Perennial increase in atmospheric pollution over the Bay of Bengal (BoB) and South China Sea is reported due to increase in human population and industrial activity in South and Southeast Asia. Based on total aerosol optical ...

Variability in stratification and flushing times of the Gautami-Godavari estuary, India

Sridevi, B.; Sarma, V.V.S.S.; Murty, T.V.R.; Sadhuram, Y.; Reddy, N.P.C.; Vijaykumar, K.; Raju, N.S.N.; JawaharKumar, CH.; Raju, Y.S.N.; Luis, R.; Kumar, M.D.; Prasad, K.V.S.R. (Indian Academy of Sciences, 2015)

In order to examine the influence of forcing (river flow and tides) and anthropogenic activities (dredging and dam regulation) on stratification, a study was conducted over a period of 19 months (June 2008– December 2009) ...
