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 ...
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, ...
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 ...
