Role of river discharge and warming on ocean acidification and pCO2 levels in the Bay of Bengal
(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 ...
Dry-deposition of inorganic and organic nitrogen aerosols to the Arabian Sea: Sources, transport and biogeochemical significance in surface waters
(Elsevier, 2021)
Air-to-sea deposition of water-soluble total nitrogen (WSTN) can influence the primary productivity in the coastal oceans. Here, we assessed the concentrations of aerosol inorganic (WSIN: NH4+ + NO3?) and WSTN over the ...
Potential mechanisms responsible for spatial variability in intensity and thickness of oxygen minimum zone in the Bay of Bengal
(AGU Wiley, 2021)
Spatial variability in boundaries and thickness of oxygen minimum zone (OMZ) is derived based on measured dissolved oxygen data obtained from sensors on board biogeochemical (BGC) Argo floats between 2013 and 2019 in the ...
Influence of river discharge on abundance and dissemination of heterotrophic, indicator and pathogenic bacteria along the east coast of India
(Elsevier, 2015)
In order to examine the influence of discharge from different rivers from peninsular India and urban sewage on intensity and dissemination of heterotrophic, indicator and pathogenic bacteria, a study was carried out during ...
Influence of phytoplankton pigment composition and primary production on pCO2 levels in the Indian Ocean
(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. ...
Book Review: Hot Carbon: Carbon-14 and a Revolution in Science
(Current Science Association, IAS, 2020)
A short review of the book titled �Hot Carbon: Carbon-14 and a Revolution in Science� authored by John F. Marra and publihsed by Columbia University Press, New York in 2019. The relevance and the description of the content ...
Acidification of the coastal Bay of Bengal by aerosols deposition
(Springer, 2021)
Polluted aerosol transport from South Asia containing oxides of nitrogen and sulphur and their deposition on surface may acidify coastal waters. To test this hypothesis, we have conducted experiments involving (a) variability ...
Potential mechanisms responsible for occurrence of core oxygen minimum zone in the north-eastern Arabian Sea
(Elsevier, 2020)
The thickness of oxygen minimum zone (OMZ) is estimated for the first time using dissolved oxygen (DO) profiles obtained from the Biogeochemical Argo floats collected between 2013 and 2019 in the Arabian Sea. The depth of ...
Decadal variations in natural and anthropogenic aerosol optical depth over the Bay of Bengal: the influence of pollutants from Indo - Gangetic Plain
(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 ...
Chemical characterization of wintertime aerosols over the Arabian Sea: Impact of marine sources and long-range transport
(Pergamon, 2020)
We examined here the compositional characteristics of total suspended particulate (TSP) samples collected along the east coast of the Arabian Sea during a winter cruise (SS379: 6-24 December 2018) to understand the extent ...
