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 ...
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, ...
Short term response of plankton community to nutrient enrichment in central eastern Arabian Sea: Elucidation through mesocosm experiments
(Elsevier, 2021)
Oligotrophic waters (OW), generally favour longer food chain facilitated by the microbial loop. In such ecosystems, physical mixing (e.g. upwelling, and winter convection) inject nutrients and propagules from subsurface ...
Relations between marine biogeochemical indices and cloud properties over the Arabian Sea
(Springer, 2021)
Knowledge of relations among ocean biogeochemical and cloud properties will help to plan experiments necessary to understand the mechanisms and processes underlying the links between ocean and atmosphere interactions. Here, ...
Elevated acidification rates due to deposition of atmospheric pollutants in the coastal Bay of Bengal
(AGU Wiley, 2021)
Human inputs of pollutants to the atmosphere and subsequent deposition may decrease pH in the coastal waters. Significant rate of decrease in pH and increase in pCO2 by 3-5 times is noticed in the coastal Bay of Bengal ...
Physical forcing controls spatial variability in primary production in the Indian Ocean
(Elsevier, 2021)
In order to examine the spatial variability and controlling factors of primary production in the Indian Ocean, deck-incubation primary production (13C method) and hydrographic properties were measured at 25 locations during ...
Phosphate removal through adsorption on suspended matter in the Bay of Bengal: Possible implications to primary production
(Springer, 2021)
Low primary production in the Bay of Bengal (BoB) could not be explained as this region receives nutrients from atmospheric deposition, rivers, eddies, and mixing due to depression/cyclones. In addition to nutrients, BoB ...
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 ...
Magnitude of river discharge determines the food habit and community composition of zooplankton in the Indian estuaries during monsoon
(Elsevier, 2021)
Zooplankton of seventeen Indian estuaries were investigated using plankton net (200- mu M mesh; 0.25 m2 mouth area) during the peak discharge period of 2011. Results showed that the seventeen estuaries are comparable in ...
