Response of phytoplankton to nutrient enrichment with high growth rates in a tropical monsoonal estuary - Zuari estuary, India
Present study is about the impact of macronutrient enrichment on phytoplankton biomass and community structure in a tropical monsoonal estuary. In situ experiments carried out during the pre-monsoon period (February-March ...
Nitrogen transformations as inferred from the activities of key enzymes in the Arabian Sea oxygen minimum zone
Vertical distributions of the potential activities of some key enzymes mediating nitrification and denitrification were investigated within the oxygen (O2) minimum zone of the Arabian Sea at a number of locations between ...
Mudbanks and fisheries along the Kerala coast-myth and reality
(Current Science Association & Indian Academy of Sciences, 2018)
Mudbanks, a unique coastal oceanographic phenomenon occurring along the southwest (SW) coast of India during the SW monsoon season, are synonymous with the fishery of this region. Here we examine the validity of the popular ...
Vulnerability of semi-enclosed marine systems to environmental disturbances
(Island Press, 2009)
Semi-enclosed marine systems (SEMSs) are impacted on time scales ranging from the very short (days or less) to the very long (decades and beyond) by many of the same forces and stresses as other components of the Earth ...
Anaerobic carbon mineralisation through sulphate reduction in the inner shelf sediments of eastern Arabian sea
Monsoon-induced coastal upwelling, land run-off, benthic and atmospheric inputs make the western Indian shelf waters biologically productive that is expected to lead to high rates of mineralisation of organic matter (OM) ...
Phytoplankton response to the contrasting physical regimes in the eastern Arabian Sea during north east monsoon
Phytoplankton abundance and composition in two contrasting physical regimes - convective mixing in the northeastern Arabian Sea (NEAS) and Arabian Sea mini warm pool (ASMWP) in the southeastern Arabian Sea (SEAS) - were ...
Enhancement of oceanic nitrous oxide emissions by storms
Evolution to decay of upwelling and associated biogeochemistry over the southeastern Arabian sea shelf
(AGU Publications, 2016)
Observations along 10 shelf transects in 2012 near 10°N in the southeastern Arabian Sea revealed the usual warm oligotrophic conditions during the winter monsoon and upwelling of oxygen-deficient, nutrient-rich cool water ...
Time Series Observations in the North Indian Ocean
Unlike the Atlantic and the Pacific Ocean, the northern Indian Ocean is geographically unique. The bounding to the north by the Asian landmass has a profound impact on the biogeochemistry of the region. The Arabian Sea ...
Biogeochemistry of iron in the Arabian sea
(Association for the Sciences of Limnology and Oceanography, 2015)
The Arabian Sea is a productive basin where seasonal upwelling and convective mixing result in high surface nutrient concentrations and widespread algal blooms. The factors controlling primary productivity in the Arabian ...
