Influence of environmental parameters on bio-optical characteristics of colored dissolved organic matter in a complex tropical coastal and estuarine region
(Elsevier BV, 2020)
Dissolved organic matter (DOM) is an important source of carbon in aquatic ecosystems, and colored DOM (CDOM), which is smaller than 0.2 mu m and interacts with ultraviolet (UV) and visible light, affects the spectral ...
Impact of physical processes on oxygen loss and production of hydrogen sulphide and methane in a tropical freshwater reservoir
(Springer, 2021)
Carbon neutrality of tropical reservoirs is a big concern in recent years as some estimates project high methane emission from these reservoirs. While there are studies available on the impact of physical processes ...
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 ...
Glacial-Holocene climate-driven shifts in lacustrine and terrestrial environments: Rock magnetic and geochemical evidence from East Antarctic Mochou Lake
(Elsevier, 2021)
Geomorphic reconstructions of the East Antarctic Ice Sheet history across Antarctica suggest diachronous and varying retreat patterns with changing climate. However, little is known of how terrestrial environments responded ...
Total organic carbon and its role in oxygen utilization in the eastern Arabian Sea
(Elsevier Ltd, 2021)
We report seasonal and temporal variation of total organic carbon (TOC) in the eastern Arabian Sea (AS). In comparison to the deep, TOC in the top 100 m showed spatial variation with higher concentrations towards northern ...
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 ...
Phytoplankton dynamics in a seasonal stratified reservoir (Tillari), Western India
(EDP Sciences, 2021)
Phytoplankton are the primary producers in all the aquatic ecosystems and play an important role in key biogeochemical processes that are linked to the higher trophic levels and climate variability. The present study deals ...
Dynamics of dimethylsulphide and associated compounds in the coastal waters of Goa, west coast of India
(Elsevier B.V., 2020)
Concentrations of total dimethylsulphoniopropionate (DMSPt), Dimethylsulphide (DMS) and total dimethylsulphoxide (DMSOt) were measured at a coastal time series site, west coast of India, from September 2009 to December ...
Controls on organic matter distribution in oxygen minimum zone sediments from the continental slope off western India
(Elsevier B.V., 2020)
The causes of organic-rich sediments in contact with the perennial oxygen minimum zone (OMZ) on the continental slope off western India have been debated extensively, largely in relation to two main controlling factors: ...
Biogeochemical cycling in the low oxygen marine environments
(Elsevier B.V., 2020)
Biogeochemistry is the interdisciplinary science of the composition and cycling of chemicalelements. Nitrogen and oxygen are two elements that are essential for living organisms and the sustenance of life on Earth. While ...
