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 ...
Phytoplankton associated with seasonal oxygen depletion in waters of the western continental shelf of India
(2020)
We report here results of a time series study carried out to understand seasonal variability of phytoplankton in relation to changes in dissolved oxygen based on observations at the Candolim Time Series (CaTS) station ...
Methane dynamics in the shelf waters of the West coast of India during seasonal anoxia
(Elsevier, 2018)
The Western Continental Shelf of India experiences water-column anoxia during late summer/early autumn, thereby providing conducive conditions for methane (CH4) accumulation. Measurements of CH4 along with other ancillary ...
Massive Nitrogen Loss Over the Western Indian Continental Shelf During Seasonal Anoxia: Evidence From Isotope Pairing Technique
(Frontiers Media SA, 2020)
The western Indian continental shelf houses the world's largest naturally formed coastal low-oxygen zone that develops seasonally during the summer monsoon. We investigated multiple reductive nitrogen transformation pathways ...
Variability of dissolved oxygen in the Arabian Sea Oxygen Minimum Zone and its driving mechanisms
(2020)
The Arabian Sea hosts one of the most intense, perennial Oxygen Minimum Zones (OMZ) in the world ocean. Observations along a meridional transect at 68°E extending from 8 to 21°N showed large seasonal as well as interannual ...
Chemolithoautotrophic denitrification intensifies nitrogen loss in the Eastern Arabian Sea Shelf waters during sulphidic events
(Elsevier, 2023)
The Eastern Arabian Sea Shelf i.e. Western Indian Continental Shelf (WICS) – a known biogeochemical hotspot is characterized by monsoonal upwelling, seasonal O2 deficiency, extremely high N2O build-up and sulphidic events. ...
The relationship between volatile halocarbons and phytoplankton pigments during a Trichodesmium bloom in the coastal eastern Arabian Sea
(Elsevier, 2011)
Eukaryotic phytoplankton such as diatoms and prymnesiophytes produce biogenic halocarbons in the ocean that serve as important sources of chlorine and bromine to the atmosphere, but the role of cyanobacteria in halocarbon ...
Dissolved methane in Indian freshwater reservoirs
(Springer, 2013)
Emission of methane (CH4), a potent greenhouse gas, from tropical reservoirs is of interest because such reservoirs experience conducive conditions for CH4 production through anaerobic microbial activities. It has been ...
Seasonally varying biogeochemical regime around the coral habitats off central west coast of India
(Elsevier, 2024)
The Western Indian Continental Shelf (WICS) experiences upwelling during the Southwest Monsoon (SWM), leading to deoxygenation and acidification of subsurface waters. The region has patchy growth of corals, e.g. in the ...
Benthic mineralization and nutrient exchange over the inner continental shelf of western India.
(European Geosciences Union, 2014)
The western Indian continental shelf is one of the most productive coastal systems of the world ocean. This system experiences extreme changes in its oxygen regime, being normoxic from November to May and suboxic ...
