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 ...
Biogeochemistry and ecology of Pyrosoma spinosum from the Central Arabian Sea
(Springer, 2015)
Background: A swarm of pelagic tunicate (Pyrosoma spinosum) was found in the surface open waters of the Arabian Sea during late southwest monsoon (September 2007). The swarm site was characterized by moderate southwesterly ...
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. ...
POC export fluxes in the Arabian Sea and the Bay of Bengal: A simultaneous 234Th/238U and 210Po/210Pb study
(Elsevier, 2018)
Seasonal variation in POC export flux, from the upper ocean, was studied during post southwest monsoon (October-November 2013) and spring intermonsoon (May 2014) at selected locations in the central and southern Arabian ...
Spatial variation of phytoplankton pigments along the southwest coast of India
(Elsevier, 2006)
Phytoplankton composition and abundance were studied along the southwestern Indian coast toward the end of the upwelling season in October 2004. Phytoplankton pigment analyses, complemented by limited microscopic counts, ...
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 ...
Ecological diversity of planktonic protists in spatial regimes of the Arabian Sea revealed through next-generation sequencing
(Elsevier, 2019)
Eukaryotic microbes inhabiting diverse ecological niches are capable of mediating biogeochemical shifts. Here, we studied the distribution patterns of protistan community in oxygen-deficient sites in the Arabian Sea and ...
A non-diatom plankton bloom controlled by copepod grazing and amphipod predation: Preliminary results from the LOHAFEX iron-fertilisation experiment
(GLOBEC, 2009)
The most memorable LOHAFEX cruise came to an end on 17 March 2009 when RV Polarstern docked in the harbour of Punta Arenas (southern Chile) after successfully carrying out the longest iron fertilisation experiment so far ...
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 ...
Seasonal variations in abundance, biomass and grazing rates of microzooplankton in a tropical monsoonal estuary
(Springer, 2015)
Seasonal abundance, composition and grazing rates of microzooplankton (20–200 µm) in the Zuari estuary were investigated to evaluate their importance in food web dynamics of a tropical monsoonal estuary. Average abundances ...
