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 ...
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 ...
Role of eddies on controlling total and size-fractionated primary production in the Bay of Bengal
(Elsevier BV, 2020)
In order to examine the role of eddies on total and size-fractionated primary production, two cyclonic (CE), one anticyclonic (ACE) and no-eddy (NE) regions were sampled in the BoB during pre-summer monsoon (June 2019). ...
Severe phosphate limitation on nitrogen fixation in the Bay of Bengal
(Elsevier BV, 2020)
Several anticyclonic (ACE) and cyclonic (CE) eddies constitute the circulation in the Bay of Bengal (BoB) and are associated with the downwelling and upwelling processes leading to oligotrophic and eutrophic conditions ...
Influence of eddies on phytoplankton composition in the Bay of Bengal
(Elsevier Ltd, 2020)
Several cyclonic (CE) and anticyclonic (ACE) eddies form in the Bay of Bengal (BoB) and they expect to contain different proportion of nutrients due to divergence and convergence of waters respectively and may have impact ...
Impact of atmospheric dry deposition of nutrients on phytoplankton pigment composition and primary production in the coastal Bay of Bengal
(Springer, 2022)
Atmospheric deposition of pollutants decreases pH and increases the nutrient concentration in the surface water.To examine its impact on coastal phytoplankton composition and primary production, monthly atmospheric aerosol ...
