Influence of upwelling induced near shore hypoxia on the Alappuzha mud banks, South West Coast of India
(Elsevier, 2017)
The results of the first time-series measurements spanning 18-weeks (22 April to 20 September 2014) from a coastal environment (Alappuzha, southwest India), where two process of upwelling and mud banks are concurrent during ...
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 ...
Dissolved and particulate iron redox speciation during the LOHAFEX fertilization experiment
(Elsevier, 2022)
The redox speciation of iron was determined during the iron fertilization LOHAFEX and for the first time, the chemiluminescence assay of filtered and unfiltered samples was systematically compared.We hypothesize that higher ...
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 ...
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 ...
Methane stimulates massive nitrogen loss from freshwater reservoirs in India
(Nature Publishing Group, 2018)
The fate of the enormous amount of reactive nitrogen released to the environment by human activities in India is unknown. Here we show occurrence of seasonal stratification and generally low concentrations of dissolved ...
Seasonal anoxia over the western Indian continental shelf
(American Geophysical Union, 2009)
The eastern Arabian Sea contains the only eastern-boundary-type upwelling environment in the entire Indian Ocean, albeit on a seasonal basis. During the southwest monsoon, when the surface current flows equatorward, upwelling ...
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 ...
Benthic fluxes in a tropical estuary and their role in the ecosystem
(Elsevier, 2009)
In-situ measurements of benthic fluxes of oxygen and nutrients were made in the subtidal region of the Mandovi estuary during premonsoon and monsoon seasons to understand the role of sediment-water exchange processes in ...
