Carbon dioxide emissions from the tropical Dowleiswaram Reservoir on the Godavari River, Southeast of India
Prasad, M.H.K.; Sarma, V.V.S.S.; Sarma, V.V.; Krishna, M.S.; Reddy, N.P.C. (Scientific Research Publishing, 2013)Time-series observations were conducted in the Dowleiswaram dam reservoir that was constructed on the largest monsoonal river in India to understand the source of inorganic carbon, and fluxes to the atmosphere. The reservoir ... -
Export fluxes of dissolved inorganic carbon to the northern Indian Ocean from the Indian monsoonal rivers
Krishna, M.S.; Viswanadham, R.; Prasad, M.H.K.; Kumari, V.R.; Sarma, V.V.S.S. (European Geosciences Union, 2019)Rivers are an important source of dissolved inorganic carbon (DIC) to the adjacent coastal waters. In order to examine the spatial variability in the distribution and major sources of DIC in the Indian monsoonal rivers and ... -
Export of dissolved inorganic nutrients to the northern Indian Ocean from the Indian monsoonal rivers during discharge period
Krishna, M.S.; Prasad, M.H.K.; Rao, D.B.; Viswanadham, R.; Sarma, V.V.S.S.; Reddy, N.P.C. (Elsevier, 2016)Coastal regions are highly productive due to the nutrients largely supplied by rivers. To examine the contribution of dissolved inorganic nutrients (DIN) by Indian rivers to coastal waters, data were collected near the ... -
Export of particulate organic carbon and nitrogen to the northern Indian Ocean by the monsoonal rivers of India
Krishna, M.S.; Prasad, M.H.K.; Naidu, S.A.; Srikanth, G.; Reddy, N.P.C.; Sarma, N.S. (Springer, 2023)This study analyses particulate organic carbon (POC) and particulate nitrogen (PN) export from Indian monsoonal rivers to the north Indian Ocean. Indian monsoonal rivers export approximately 1.2 Tg yr−1 (1Tg = 1012 g) of ... -
Influence of phytoplankton pigment composition and primary production on pCO2 levels in the Indian Ocean
Sarma, V.V.S.S.; Prasad, M.H.K.; Dalabehera, H.B. (Springer, 2021)The tropical Indian Ocean is a net sink for the carbon dioxide (CO2) in the atmosphere and phytoplankton production plays a crucial role in CO2 fixation and determines the direction of CO2 flux at the sea-to-air interface. ... -
Spatial variability in plankton metabolic balance in the tropical Indian Ocean during spring intermonsoon
Sarma, V.V.S.S.; Prasad, M.H.K.; Sherin, C.K.; Mangalaa, K.R. (Elsevier, 2023)The tropical Indian Ocean consists of three basins, namely the Arabian Sea (AS), Bay of Bengal (BoB) and Southern Indian Ocean (SIO), with relatively nutrient-rich waters in the former two basins. It is hypothesized that ... -
Spatial variations in dissolved inorganic nutrients in the groundwaters along the Indian coast and their export to adjacent coastal waters
Kumar, B.S.K.; Viswanadham, R.; Kumari, V.R.; Rao, D.B.; Prasad, M.H.K.; Srinivas, N.; Sarma, V.V.S.S. (Springer, 2021)Submarine Groundwater Discharge (SGD) is one of the main external nutrient sources to the coastal waters. The concentrations of nutrients in groundwaters are a few folds higher than that of adjacent coastal waters; therefore, ... -
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 ...
