Autonomous profiling float observations reveal the dynamics of deep biomass distributions in the denitrifying oxygen minimum zone of the Arabian Sea
(Elsevier B.V., 2020)
Data from 13 autonomous profiling BGC-Argo floats, equipped with biogeochemical and bio-optical sensors deployed between 2011 and 2016, were used to explore the potential of bio-optical methods to map deep biomass distribution ...
Role of oceanic fronts in enhancing phytoplankton biomass in the eastern Arabian Sea during an oligotrophic period
(Elsevier Ltd, 2020)
In the present study, using in-situ and satellite observations, we investigate the influence of physical processes on the enhancement of phytoplankton biomass in the eastern Arabian Sea (EAS). Water column measurements ...
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 ...
Variation in phytoplankton community and its implication to dimethylsulphide production at a coastal station off Goa, India
(Elsevier Ltd, 2020)
Seasonal hypoxia/suboxia (at times anoxia) towards the end of Southwest monsoon (SWM; June to September) at the coastal time series site off Goa, West coast of India was found to influence the dynamics of phytoplankton ...
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 ...
Meta-analysis cum machine learning approaches address the structure and biogeochemical potential of marine copepod associated bacteriobiomes
(Springer-Nature, 2021)
Copepods are the dominant members of the zooplankton community and the most abundant form of life. It is imperative to obtain insights into the copepod-associated bacteriobiomes (CAB) in order to identify specific bacterial ...
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 ...
A comparative study on microzooplankton communities in two tropical monsoonal estuaries
(Elsevier, 2021)
We studied on microzooplankton (MZP) communities from two major rivers, the Mandovi and the Zuari estuarine system of Goa on central west coast India. Despite both estuaries having a common point of discharge (eastern part ...
Environmental association of heterotrophic micro-eukaryotes in the varying biogeochemical regimes of the Arabian Sea, resolved via high-throughput sequencing
(Springer, 2021)
The diverse physicochemical conditions prevailing in the Arabian Sea are expected to result in marked spatial variations in heterotrophic flagellate (HF) and ciliate communities. Here, we report the environmental association ...
Benthic exchange along a tropical estuarine salinity gradient during dry season: Biogeochemical and ecological implications
(Elsevier, 2021)
Benthic biogeochemistry and its coupling with pelagic ecology are less understood in tropical than in temperate estuaries, which have significant implications for global carbon and nutrient cycling. In dry season, the ...
