234Th scavenging and particle export fluxes from the upper 100 m of the Arabian Sea
(Current Science Association, 1996)We have determined the particle scavenging rates, export fluxes of @u234@@Th and settling particles from the upper 100 m of the Arabian Sea as a part of the JGOFS (India) Programme. The spatial and temporal measurements ... -
A study on inorganic carbon components in the Andaman Sea during the post monsoon season
(Ifremer/ CNRS/ IRD/ Editions scientifiques et medicales Elsevier SAS. Tous droits reserves, 2001)Extensive data have been collected on the carbon dioxide system during the post monsoon season in the eastern Bay of Bengal and the Andaman Sea of the northeastern Indian Ocean. The vertical distribution of temperature and ... -
An intermediate nepheloid layer associated with high microbial metabolic rates and denitrification in the northwest Indian Ocean
(American Geophysical Union, 1993)Extensive optical, physical chemical, and biochemical measurements made simultaneously in the northwest Indian Ocean reveal the occurrence of an intermediate nepheloid layer (INL) invariably associated with the secondary ... -
Carbon cycling in the northern Arabian Sea during the northeast monsoon: Significance of salps
(Inter-Research, 2002)Winter cooling and mixing brings nutrients (nitrate and phosphate) to the surface waters over large parts of the northern Arabian Sea, but the rates of primary production as well as carbon export from the euphotic zone are ... -
Carbonate and carbon fluctuations in the Eastern Arabian Sea over 140 ka: Implications on productivity changes?
(Elsevier, 2005)Biological productivity in the western Arabian Sea was higher during interglacial than glacial times. In the eastern Arabian Sea productivity was higher during the glacials compared to interglacials, which is in sharp ... -
Contribution of Phytoplankton Photosynthesis to a Mangrove Ecosystem
(Indian Association for Limnology and Oceanography, 1980)Primary production in a fringing mangrove ecosystem was measured using two techniques. The first estimated gross oxygen production and community metabolism based on the diel difference in dissolved oxygen concentrations. ... -
Distribution and sources of organic matter in surface sediments of the eastern continental margin of India
(American Geophysical Union, 2013)The sources and distribution of organic matter (OM) in surface sediments of the eastern continental margin of India, including the region influenced by river discharge, were investigated using content, molar C:N ratios and ... -
Elemental (C, H, N) composition of zooplankton from north Arabian Sea
(NISCAIR, CSIR, 1995)Zooplankton samples collected from north Arabian Sea during March 1992 were analysed for elemental (C,H,N) composition. Estimated carbon, hydrogen and nitrogen concentrations displayed variations among different groups but ... -
Enhanced export of carbon by salps during the northeast monsoon period in the northern Arabian Sea
(Elsevier, 2005)A drifting sediment trap was deployed and sup(234)Th activity in the water column was measured to calculate export flux of carbon at a time-series station in the northern Arabian Sea (lat. 21 degrees 30 minutes N; long. ... -
Hydrochemistry of the Bay of Bengal: Possible reasons for a different water-column cycling of carbon and nitrogen from the Arabian Sea
(Elsevier, 1994)A study on biogeochemical cycling in the western Bay of Bengal was undertaken during two seasons (pre-southwest monsoon and northeast monsoon of 1991). Relationships of the conservative tracers NO and PO with potential ... -
Litter fall and energy flux in a mangrove ecosystem
(Academic Press, 1997)Production, elemental composition and In situ decomposition of litter of Rhizophora apiculata, R. mucronata, Sonneratia alba and Avicennia offcinalis were studied in a mangrove ecosystem fringing Mandovi-Zuari Estuaries ... -
Nutrient uptake and regeneration ratios in the Red sea with reference to the nutrient budgets
(Elsevier, 1986)The relationships between apparent oxygen utilization and inorganic micronutrients have been studied on the basis of extensive observation in the Red Sea. The ratios obtained are - Delta AOU: Delta SiO4: Delta NO3: Delta ... -
Organic matter composition in sediments of the Oman margin
(Taylor and Francis, 2003)The quantity and biochemical composition of organic matter (OM) in the sediments underlying and below oxygen minimum zone (OMZ) in the Arabian Sea were studied to provide information on the diagenetic processes of organic ... -
Seasonal variations in carbon biomass of bacteria, thraustochytrids and microzooplankton in the northern Arabian Sea
(Elsevier, 2005)As a part of the JGOFS-India Programme, abundance of heterotrophic bacteria (Hbac; 0-2000 m), thraustochytrids (0-2000 m), microzooplankton (0-200m occasionally up to 300 m) as well as bacterial growth rates (0-500 m) were ... -
Seasonal variations in inorganic carbon components in the central and eastern Arabian Sea
(Current Science Association, Bangalore, India, 1996)Extensive observations have been made on the carbon dioxide system in the Arabian Sea during three different seasons as part of the Indian Joint Global Ocean Flux Study (JGOFS) Programme. Concentrations of total carbon ... -
sup(234) Th scavenging and particle export fluxes from the upper 100 m of the Arabian Sea
(Current Science Association, Bangalore, India, 1996)We have determined the particle scavenging rates, export fluxes of sup(234) Th and settling particles from the upper 100 m of the Arabian Sea as a part of the JGOFS (India) Programme. The spatial and temporal measurements ... -
The carbon budget of South Asia
(European Geosciences Union, 2013)The source and sinks of carbon dioxide (CO sub(2)) and methane (CH sub(4)) due to anthropogenic and natural biospheric activities were estimated for the South Asian region (Bangladesh, Bhutan, India, Nepal, Pakistan and ...
