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, ...
Nitrogen fixation in the western coastal Bay of Bengal: Controlling factors and contribution to primary production
(Elsevier, 2022)
N2 fixation rates were measured at 18 stations in the western coastal Bay of Bengal (BoB) to evaluate its contribution to the external source of nitrogen and its controlling factors. During the study period (fall monsoon), ...
Seasonal, weathering and water use controls of silicon cycling along the river flow in two contrasting basins of South India
(Elsevier, 2022)
We present the first study of river water silicon isotopic composition from two contrasting basins in South India, the east flowing Kaveri river and the west flowing Netravathi river. Both rivers originate from the Western ...
Enhanced Atmospheric Pollutants Strengthened Winter Convective Mixing and Phytoplankton Blooms in the Northern Arabian Sea
(Wiley, 2022)
The recent increase in atmospheric pollutants (aerosols) over the northern Indian Ocean due to an increase in industrial activity in South and Southeast Asia decreased air temperature (AT) leading to the strengthening of ...
Impact of atmospheric anthropogenic nitrogen on new production in the northern Indian Ocean: Constrained based on satellite aerosol optical depth and particulate nitrogen levels
(The Royal Society of Chemistry, 2022)
Aerosols are one of the significant external sources of soluble reactive nitrogen to the surface ocean and their deposition affects the primary productivity.Owing to rapid industrialization over South and Southeast Asia, ...
