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 ...
Phytoplankton response to the contrasting physical regimes in the eastern Arabian Sea during north east monsoon
(Elsevier, 2018)
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 ...
Remarkable structural resistance of a nanoflagellate-dominated plankton community to iron fertilization during the Southern Ocean experiment LOHAFEX
(Inter-Research Science Center, Oldendorf/Luhe, Germany, 2018)
The genesis of phytoplankton blooms and the fate of their biomass in iron-limited, high-nutrient-low-chlorophyll regions can be studied under natural conditions with ocean iron fertilization (OIF) experiments. The Indo-German ...
Fragilariopsis sp. bloom causes yellowish-brown waters off Alappuzha, south-central Kerala coast, India, during the mud bank-upwelling phase
(Current Science Association & Indian Academy of Sciences, 2018)
Mud banks (Chakara) of Kerala are calm coastal waters that form in several isolated stretches along the coast usually during the southwest monsoon (SWM) period (June-September). They are characterized by the damping of ...
Biogeochemistry of methane in a tropical monsoonal estuarine system along the west coast of India
(Elsevier, 2018)
Estuaries are known to be important sources of methane (CH4) to the atmosphere. However, a lack of adequate field studies in understanding the sources/sinks of CH4 in estuaries hampers the global atmospheric budgeting. ...
Variations in Denitrification and Ventilation Within the Arabian Sea Oxygen Minimum Zone During the Holocene
(John Wiley & Sons, 2018)
The continental slope of India is exposed to an intense perennial oxygen minimum zone (OMZ) supporting pelagic denitrification. Sediments that are presently in contact with the lower boundary of the denitrification zone ...
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 ...
Methane dynamics in the shelf waters of the West coast of India during seasonal anoxia
(Elsevier, 2018)
The Western Continental Shelf of India experiences water-column anoxia during late summer/early autumn, thereby providing conducive conditions for methane (CH4) accumulation. Measurements of CH4 along with other ancillary ...
Mud Banks along the southwest coast of India are not too muddy for plankton
(2018)
Considering Alappuzha Mud Bank in the southern Kerala coast as a typical case of biologically productive Mud Banks that form along the southwest coast of India during the Southwest Monsoon (June - September), the present ...
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 ...
