Upper layer thermohaline structure of the Bay of Bengal during the 2013 northeast monsoon
(Elsevier Ltd, 2020)
The Bay of Bengal is forced by the South Asian monsoon and associated seasonally reversing winds and freshwater fluxes. Here, we summarize a high-resolution, basin-wide survey of the Bay of Bengal conducted during the 2013 ...
Release of significant fraction of primary production as dissolved organic carbon in the Bay of Bengal
(Elsevier Ltd, 2021)
Despite nutrients supply through river discharge, atmospheric deposition and eddy-driven mixing, low primary production in the Bay of Bengal (BoB) is attributed to light limitation and non-availability of nutrients during ...
Sources of organic matter and tracing of nutrient pollution in the coastal Bay of Bengal
(Pergamon, 2020)
Stable isotopic composition of carbon (delta13CPOM) and nitrogen (delta15NPOM) in the particulate organic matter (POM) is used to identify sources of organic carbon and nutrients using monthly time-series observation in ...
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 ...
A revisit to the regulation of oxygen minimum zone in the Bay of Bengal
(Springer, 2020)
Occurrence of intense oxygen minimum zone (OMZ) is known in the Bay of Bengal (BoB), but it has been recently reported to have become more acute and is at its tipping point. Here, we show that the intensification of OMZ ...
A significant shift in particulate organic matter characteristics during flooding of River Krishna, eastern peninsular India
(Current Science Association, IAS, 2020)
Extremely heavy rainfall over a small, semi-arid section of the Indian Peninsula in October 2009, together with release of water from dams resulted in very severe flooding in River Krishna. The sources and type of organic ...
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 ...
Spatial and temporal variability in concentration and characteristics of aerosols at Visakhapatnam (east) and Goa (west) coasts of India
(2020)
Knowledge on the variability in quantity and compositions of various size groups of aerosols is important to understand their sources and their role in biogeochemical and climate processes. Here, we studied total suspended ...
Spatial variations in dissolved inorganic nutrients in the groundwaters along the Indian coast and their export to adjacent coastal waters
(Springer, 2021)
Submarine Groundwater Discharge (SGD) is one of the main external nutrient sources to the coastal waters. The concentrations of nutrients in groundwaters are a few folds higher than that of adjacent coastal waters; therefore, ...
