Carbon dioxide emissions from Indian monsoonal estuaries
Sarma, V.V.S.S.; Viswanadham, R.; Rao, G.D.; Prasad, V.R.; Kumar, B.S.K.; Naidu, S.A.; Kumar, N.A.; Rao, D.B.; Sridevi, T.; Krishna, M.S.; Reddy, N.P.C.; Sadhuram, Y.; Murty, T.V.R. (American Geophysical Union, 2012)Estuaries are known to be strong source for atmospheric CO sub(2), however, little information is available from Indian estuaries. In order to quantify CO sub(2) emissions from the Indian estuaries, samples were collected ... -
Contribution of N<sub>2</sub>O emissions to the atmosphere from Indian monsoonal estuaries
Rao, G.D.; Sarma, V.V.S.S. (International Meteorological Institute, 2013)Estuaries are known to contribute a significant amount of nitrous oxide (N<sub>2</sub>O) to the atmosphere; however, the contribution from the Indian estuaries is unknown. We made an attempt to estimate emissions of ... -
Distribution and air–sea exchange of nitrous oxide in the coastal Bay of Bengal during peak discharge period (southwest monsoon)
Rao, G.D.; Rao, V.D.; Sarma, V.V.S.S. (Elsevier, 2013)In order to examine the impact of river discharge from the Indian subcontinent on the concentration and air–sea exchange of nitrous oxide (N sub(2)O) a study was conducted during peak discharge period in the coastal Bay ... -
Distribution and sources of particulate organic matter in the Indian monsoonal estuaries during monsoon
Sarma, V.V.S.S.; Krishna, M.S.; Prasad, V.R.; Kumar, B.S.K.; Naidu, S.A.; Rao, G.D.; Viswanadham, R.; Sridevi, T.; Kumar, P.P.; Reddy, N.P.C. (American Geophysical Union, 2014)The distribution and sources of particulate organic carbon (POC) and nitrogen (PN) in 27 Indian estuaries were examined during the monsoon using the content and isotopic composition of carbon and nitrogen. Higher phytoplankton ... -
Effects of freshwater stratification on nutrients, dissolved oxygen, and phytoplankton in the Bay of Bengal
Sarma, V.V.S.S.; Rao, G.D.; Viswanadham, R.; Sherin, C.K.; Salisbury, J.; Omand, M.M.; Mahadevan, A.; Murty, V.S.N.; Shroyer, E.; Baumgartner, M.; Stafford, K. (The Oceanography Society, 2016)The Bay of Bengal (BoB) is strongly density stratified due to large freshwater input from various rivers and heavy precipitation. This strong vertical stratification, along with physical processes, regulates the transport ... -
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 ... -
Influence of river discharge on the distribution and flux of methane in the coastal Bay of Bengal
Rao, G.D.; Sarma, V.V.S.S. (Elsevier, 2017)Rivers are known to be strong sources of methane (CH4) to the atmosphere and their discharges may also enhance its flux from the coastal ocean. In order to examine this, CH4 fluxes to the atmosphere were examined along the ... -
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 ... -
Modifications in the trace gases flux by a very severe cyclonic storm, Hudhud, in the coastal Bay of Bengal
Kumari, V.R.; Sarma, V.V.S.S.; Rao, G.D.; Viswanadham, R.; Navita, B.; Srinivas, T.N.R.; Krishna, M.S.; Reddy, N.P.C. (2019)A very severe cyclonic storm, Hudhud, made landfall at Visakhapatnam city, the central east coast of India, on 12 October 2014 and it is the most destructive cyclone to ever hit the Indian subcontinent since the past two ... -
New to total primary production ratio (f-ratio) in the Bay of Bengal using isotopic composition of suspended particulate organic carbon and nitrogen
Sherin, C.K.; Sarma, V.V.S.S.; Rao, G.D.; Viswanadham, R.; Omand, M.M.; Murty, V.S.N. (Elsevier, 2018)Variations in the content and isotopic compositions of carbon and nitrogen in the suspended particulate matter were analysed to identify sources of nutrients and compute f-ratios (ratio of new production to primary production) ... -
Suppressed biological production in the coastal waters off Visakhapatnam, India under the impact of the very severe cyclonic storm Hudhud
Sarma, V.V.S.S.; Srinivas, T.N.R.; Kumari, V.R.; Prasad, M.H.K.; Dalabehera, H.B.; Satyanarayana, U.; Rao, G.D.; Rao, D.B.; Paul, Y.S.; Murty, V.S.N.; Krishna, M.S.; Reddy, N.P.C. (2019)Tropical cyclones generally enhance biological production due to the increase in nutrients input due to vertical mixing. In contrast, the very severe cyclonic storm (VSCS) Hudhud decreased primary production due to the ... -
Variability in concentrations and fluxes of methane in the Indian estuaries
Rao, G.D.; Sarma, V.V.S.S. (Coastal and Estuarine Research Federation, 2016)In order to examine the fluxes of methane (CH4) from the Indian estuaries, measurements were carried out by collecting samples from 26 estuaries along the Indian coast during high discharge (wet) and low water discharge ...
