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 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 ...
Unraveling the sources of atmospheric organic aerosols over the Arabian Sea: Insights from the stable carbon and nitrogen isotopic composition
(Elsevier, 2022)
The isotopic composition of stable carbon (δ 13 C) and nitrogen (δ 15N) in marine aerosols influenced by the continental outflows are useful proxies for understanding the aging and secondary formation processes. Every ...
Reassessing riverine carbon dioxide emissions from the Indian subcontinent
(Elsevier, 2022)
Anthropogenic perturbations are increasing uncertainties in estimating CO2 emissions via air-water CO2 flux (FCO2) from large rivers of the Indian subcontinent. This study aimed to provide an improved estimate of the total ...
Accumulation of dissolved organic carbon and nitrogen in the photic zone in the nitrogen-depleted waters of the Bay of Bengal
(Elsevier, 2022)
Dissolved organic matter (DOM) accumulates in the upper ocean for several days to years and supports both autotrophic and heterotrophic activities. To examine the source of DOM and its role in plankton metabolic processes, ...
Temporal variations in the chemical composition of aerosols over the coastal Bay of Bengal
(Elsevier, 2022)
Variations in source, ionic composition and carbonaceous components of aerosols are expected in the atmosphere due to reversing the direction of winds from winter to summer over the coastal Bay of Bengal (BoB). To examine ...
Phytoplankton community structure is governed by salinity gradient and nutrient composition in the tropical estuarine system
(Elsevier, 2022)
Primary production in the estuarine ecosystems is principally represented by phytoplankton. The presence or function of phytoplankton in estuarine production is mainly regulated by factors such as salinity, light, turbidity, ...
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 ...
