Spatiotemporal variation of alkaline phosphatase activity in coastal waters off Trivandrum
(Elsevier, 2019)
Phosphatase is an extracellular enzyme which releases inorganic phosphate (Pi) from dissolved organic phosphate and indirectly organic carbon as nutrients for aquatic communities. Here, we have examined spatiotemporal ...
A first report on a bloom of the marine prymnesiophycean, Phaeocystis globosa from the Arabian Sea
(Ifremer/ CNRS/ IRD/ Editions scientifiques et medicales Elsevier SAS. Tous droits reserves, 2000)
A thick bloom of the marine prymnesiophycean, Phaeocystis globosa was observed in the central Arabian Sea during the summer monsoon period (July-August, 1996). The cells were mostly in colonial form, embedded in gelatinous ...
Physical control of primary productivity on a seasonal scale in central and eastern Arabian Sea
(Indian Academy of Sciences, 2000)
Using in situ data collected during 1992-1997, under the Indian programme of Joint Global Ocean Flux Study (JGOFS), it is shown that the biological productivity of the Arabian Sea is tightly coupled to the physical forcing ...
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 ...
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 ...
Spatial variability of copepod species distribution in the eastern Arabian Sea in pre-monsoon conditions
(Elsevier, 2018)
This work examines the spatial variability among mesozooplankton abundance and copepod species diversity along the continental margin prior to the onset of southwest monsoon in the eastern Arabian Sea during the year 2011. ...
Seasonal controls on surface pCO2 in the central and eastern Arabian Sea
(Indian Academy of Sciences, 2000)
The variability in partial pressure of carbon dioxide (pCO2) and its control by biological and physical processes in the mixed layer (ML) of the central and eastern Arabian Sea during inter-monsoon, northeast monsoon, and ...
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 ...
