Phytoplankton response to the contrasting physical regimes in the eastern Arabian Sea during north east monsoon
(Elsevier, 2018)
Phytoplankton abundance and composition in two contrasting physical regimes - convective mixing in the northeastern Arabian Sea (NEAS) and Arabian Sea mini warm pool (ASMWP) in the southeastern Arabian Sea (SEAS) - were ...
Variations of Colored Dissolved Organic Matter in the Mandovi Estuary, Goa, During Spring Inter-Monsoon: A Comparison With COVID-19 Outbreak Imposed Lockdown Period
(Frontiers, 2021)
Colored dissolved organic matter (CDOM) is one of the important fractions of dissolved organic matter (DOM) that controls the availability of light in water and plays a crucial role in the cycling of carbon. High CDOM ...
pH variability off Goa (eastern Arabian Sea) and the response of sea urchin to ocean acidification scenarios
(Blackwell Publishing Ltd, 2020)
The increasing atmospheric CO2 concentration in the last few decades has resulted in a decrease in oceanic pH. In this study, we assessed the natural variability of pH in coastal waters off Goa, eastern Arabian Sea. pHT ...
Geochemistry of sediments in contact with oxygen minimum zone of the eastern Arabian Sea: Proxy for palaeo-studies
(Springer, 2022)
The Arabian Sea encompasses oxygen minimum zone with denitrifying conditions. For the present study, sediments were collected across three transects off Goa transect (GT), Mangalore transect (MT) and Kochi transect (KT) ...
Characterization of colored dissolved organic matter along the western continental shelf of India during the seasonal hypoxia
(Elsevier, 2022)
In recent years the number of hypoxic zones in the world is rising, which has been attributed to the increase in nutrients and organic matter due to anthropogenic activities. Here we present results on the variations in ...
Aeolian Dust and Sea Salt in Marine Aerosols over the Arabian Sea during the Southwest Monsoon: Sources and Spatial Variability
(American Chemical Society, 2022)
The nutrient supply to the oceanic surface water is largely regulated by the extrinsic and intrinsic ambient atmospheric aerosol properties, particularly chemistry. In this context, we measured the comprehensive chemical ...
Seasonal distribution of trace metals in suspended particulate and bottom sediments of four microtidal river estuaries, west coast of India
(2019)
The seasonal distribution of metals (V, Cr, Co, Cu, Ni, Zn, Pb, Mn, Fe, Al and Ti) in suspended and bottom sediments of four minor estuaries (Terekhol, Chapora, Sal and Talpona rivers) of Goa, India was investigated to ...
Variation of biogenic sulphur compounds in the estuarine and coastal waters of Goa, West coast of India
(NIScPR-CSIR, India, 2022)
Dimethylsulphide (DMS) originates predominantly from dimethylsulphoniopropionate (DMSP), a metabolite produced by phytoplankton.Through its contribution to the production of new aerosols and cloud condensation nuclei, a ...
Recurrence of Gonyaulax polygramma bloom in the southeastern Arabian Sea
(Springer, 2023)
Gonyaulax polygramma, a bloom-forming dinoflagellate, has been repeatedly observed along the southeastern Arabian Sea in recent years. During our study in October 2021, a patch of reddish-brown water was observed in the ...
Spatial and seasonal variations in the particulate sinking flux in the Bay of Bengal
(Elsevier, 2023)
Sediment traps have been widely used to study particles sinking through the oceanic water column. As part of the SIBER-INDIA program, sediment traps were deployed at three depths ? 430 m (shallow), 1020 m (middle), and ...
