The Arabian Sea as a high-nutrient, low-chlorophyll region during the late southwest monsoon
(European Geosciences Union, 2010)
Extensive observations were made during the late southwest monsoon of 2004 over the Indian and Omani shelves, and along a transect that extended from the southern coast of Oman to the central west coast of India, tracking ...
Spatial variability in phytoplankton community structure along the eastern Arabian Sea during the onset of south-west monsoon
(Elsevier, 2016)
The Arabian Sea experiences moderate to weak upwelling along the south-west coast of India, which subsequently propagates towards the north. This causes variation in plankton community composition, which is addressed in ...
Nitrogen fixation rates in the eastern Arabian Sea
(Elsevier, 2017)
The Arabian Sea experiences bloom of the diazotroph Trichodesmium during certain times of the year when optimal sea surface temperature and oligotrophic condition favour their growth. We measured nitrogen fixation rates ...
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 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 ...
Nitrogen fixation and carbon uptake in a tropical estuarine system of Goa, western India
(Elsevier, 2019)
Biological production in aquatic systems is often nitrogen limited. Nitrogen (N2) fixation is an important contributor to nitrogen requirement of phytoplankton not only in oligotrophic but also in nutrient-replete waters. ...
Cyclone phyan-induced plankton community succession in the coastal waters off Goa, India
(Current Science Association, 2016)
Effects of the cyclonic storm Phyan, which hit the states of Goa and Maharashtra in western India during 9-12 November 2009, on coastal waters were studied. Mixing induced by the cyclone appreciably affected the vertical ...
Production of dimethylsulphide during the seasonal anoxia off Goa
(Springer, 2012)
Subsurface waters over the western Indian continental shelf experience seasonal anoxia towards the end of the southwest monsoon season. During a 3-day study carried out at the Candolim time series site (off the coast of ...
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 ...
