A new climatology of depth of nitracline in the Bay of Bengal for improving model simulations
Sridevi, B.; Ashitha, M.K.; Sarma, V.V.S.S.; Bhaskar, T.V.S.U.; Chakraborty, K.; Bhavani, I.V.G.; Valsala, V. (John Wiley & Sons, Ltd, 2024)The dissolved nitrate is one of the major essential nutrients for primary production in the tropical ocean and it is brought to the surface though mixing. The depth of nitracline determines how much of nitrate enters to ... -
A reduction in marine primary productivity driven by rapid warming over the tropical Indian Ocean
Roxy, M.K.; Modi, A.; Murtugudde, R.; Valsala, V.; Panickal, S.; PrasannaKumar, S.; Ravichandran, M.; Vichi, M.; Levy, M. (American Geophysical Union, 2016)Among the tropical oceans, the western Indian Ocean hosts one of the largest concentrations of marine phytoplankton blooms in summer. Interestingly, this is also the region with the largest warming trend in sea surface ... -
Dominant Biological Control Over Upwelling on pCO2 in Sea East of Sri Lanka
Chakraborty, K.; Valsala, V.; Gupta, G.V.M.; Sarma, V.V.S.S. (John Wiley & Sons, 2018)Upwelling enhances pCO2 levels due to injection of carbon-rich water to the surface despite the removal of carbon due to increase in primary production supported by enhanced nutrients. It is hypothesized that in the Bay ... -
Indian Ocean Acidification and Its Driving Mechanisms Over the Last Four Decades (1980 2019)
Chakraborty, K.; Joshi, A. P.; Ghoshal, P.K.; Baduru, B.; Valsala, V.; Sarma, V. V.S. S. (Wiley Online Library, 2024)Abstract This paper aims to study the changes in the Indian Ocean seawater pH in response to the changes in sea-surface temperature, sea-surface salinity, dissolved inorganic carbon (DIC), and total alkalinity (ALK) over ... -
Sea–air CO2 fluxes in the Indian Ocean between 1990 and 2009
Sarma, V.V.S.S.; Lenton, A.; Law, R.M.; Metzl, N.; Patra, P.K.; Doney, S.C.; Lima, I.D.; Dlugokencky, E.; Ramonet, M.; Valsala, V. (European Geosciences Union, 2013)The Indian Ocean (44° S–30° N) plays an important role in the global carbon cycle, yet it remains one of the most poorly sampled ocean regions. Several approaches have been used to estimate net sea–air CO<sub>2</sub> fluxes ...
