Atmospheric deposition and surface stratification as controls of contrasting chlorophyll abundance in the North Indian Ocean
(American Geophysical Union, 2007)
Intense upwelling during summer and convection in winter are believed to drive higher biological productivity in the Arabian Sea than in the Bay of Bengal. Although the Arabian Sea receives substantial atmospheric deposition ...
Controls of dimethyl sulphide in the Bay of Bengal during BOBMEX-Pilot cruise 1998
(Indian Academy of Sciences, 2000)
The air-sea exchange is one of the main mechanisms maintaining the abundances of trace gases in the atmosphere. Some of these, such as carbon dioxide and dimethyl sulphide (DMS), will have a bearing on the atmospheric heat ...
Impact of sinking carbon flux on accumulation of deep-ocean carbon in the Northern Indian Ocean
(Springer, 2007)
The export of carbon through the biological pump from the surface to the deep ocean has a direct influence on the removal of CO sub(2) from the atmosphere. This is because the carbon is sequestered for only a few days to ...
Biogeochemical significance of transport exopolymer particles in the Indian Ocean
(American Geophysical Union, 1998)
The behaviour of Transparent Exopolymer Particles (TEP), produced by biochemical processes, was studied for the North Indian Ocean, an area of global biogeochemical significance, during 1996 southwest monsoon. Very different ...
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 ...
Contribution of tropical cyclones to the air-sea CO2 flux: A global view
(American Geophysical Union, 2012)
Previous case studies have illustrated the strong local influence of tropical cyclones (TCs) on CO sub(2) air-sea flux (F sub(CO2)), suggesting that they can significantly contribute to the global F sub(CO2). In this study, ...
Influence of atmospheric dry deposition of inorganic nutrients on phytoplankton biomass in the coastal Bay of Bengal
(Elsevier, 2016)
The aerosols from continents contain relatively higher amounts of inorganic nutrients than those of marine origin and can make a notable contribution to the coastal biological productivity. To test this hypothesis, the ...
Export fluxes of dimethylsulfoniopropionate and its break down gases at the air-sea interface
(American Geophysical Union, 2002)
Dimethylsulfide (DMS) results from the decomposition of dimethylsulfoniopropionate (DMSP), a biogenic product, in seawater. Diffusive transfer of DMS from sea-to-air is known to be the most important source of natural ...
Emission of carbon dioxide from a tropical estuarine system, Goa, India
(American Geophysical Union, 2001)
Carbon dioxide species were studied in Mandovi-Zuari system, a tropical estuarine complex influenced by strong monsoonal run-off, with implications to build up and air-water exchange of CO sub(2) . Total carbon dioxide ...
Meso-scale atmospheric events promote phytoplankton blooms in the coastal Bay of Bengal
(Indian Academy of Sciences, 2011)
The Bay of Bengal is considered to be a low productive region compared to the Arabian Sea based on conventional seasonal observations. Such seasonal observations are not representative of a calendar year since the conventional ...
