Organic carbon and iron modulate nitrification rates in mangrove swamps of Goa, south west coast of India
(Elsevier, 2009)Nitrification, fuelled by ammonium is the pivotal oxidative pathway to nitrogen cycling. In spite of its ecological significance, the factors regulating nitrification rates in the benthic realm remain poorly understood. ... -
Organic Carbon content of Tropical Zooplankton
(CSIR-NISCAIR, 1980)In the Zuari and Mandovi estuaries variations in organic carbon of zooplankton are 26.4-38.8 and 24-39.9% of dry weight respectively. Maximum carbon content of estuarine zooplankton is observed in November. Organic carbon ... -
Organic carbon content of zooplankton from the nearshore waters of Bombay
(CSIR-NISCAIR, 1983)Organic carbon content of zooplankton in the Versova Creek and Thana Creek (polluted areas), off Versova and off Mahim, Bombay, India (relatively unpolluted areas) varied respectively from 21.4-30, 13.2-38.4, 21.6-30 and ... -
Organic carbon dynamics in the continental shelf waters of the eastern Arabian Sea
(Springer, 2022)The seasonal and spatial distribution of total organic carbon (TOC) is presented for the coastal waters of the eastern Arabian Sea, which experiences seasonal suboxia during the late southwest monsoon (SWM).This study ... -
Organic carbon in Antarctic snow: spatial trends and possible sources
(American Chemical Society, 2011)Organic carbon records in Antarctic snow are sparse despite the fact that it is of great significance to global carbon dynamics, snow photochemistry, and air–snow exchange processes. Here, surface snow total organic carbon ... -
Organic carbon in sediments of the southwestern margin of India: Influence of productivity and monsoon variability during the Late Quaternary
(Geological Society of India, 2007)The texture, organic carbon (OC), CaC03 and Rock-Eval parameters of the sediments from two gravity cores collected at depths below the oxygen minimum zone (OMZ) of the southwestern margin of India are presented and compared ... -
Organic carbon in the sediments of Mandovi estuary, Goa
(NISCAIR, New Delhi, 1991)Total organic carbon (TOC) in surficial sediments in Mandovi Estuary, Goa, India varies widely from 0.1 to 3% (av. 1.05%). Highest values of TOC (2.4-3%) lie close to the mouth region and indicate no definite trend in its ... -
Organic carbon in the sediments of the lower reaches of Periar River
(Indian Fisheries Association, 1992)Sediments are indicators of the quality of water overlying them and hence, useful in the assessment of environmental pollution. Temporal and spatial variations in sediment characteristics and organic carbon content from 9 ... -
Organic carbon pattern and foraminiferal assemblage in the sediments of Gulf of Kutch
(Delhi: Hindustan Pub. Co, 1973)The organic carbon/matter distribution pattern in the shallow restricted marine environment of the Gulf indicates very low values but it is found to rise as the particle size of the sediment decreases; however it appears ... -
Organic carbon removal in the sea: the continental connection
(Geological Society of London, 1992)Time series sediment traps have been deployed since May 1986 in the Arabian Sea and since October 1987 in the Bay of Bengal. The results of one and a half years from the western, central, and eastern Arabian Sea and of one ... -
Organic carbon, and not copper, controls denitrification in oxygen minimum zones of the ocean
(Elsevier, 2008)Incubation experiments under trace metal clean conditions and ambient oxygen concentrations were used to investigate the response of microbial assemblages in oxygen minimum zones (OMZs) to additions of organic carbon and ... -
Organic carbon-sulfur relationships in sediment cores from the western and eastern continental margins of India
(Elsevier, 1994)Two sediment cores from the western continental margin (WMI, WM2) and one core from the eastern continental margin (EM) of India have been analysed to determine the relativ importance of factors such as oxidizing/reducing ... -
Organic detritus of a tropical estuary

Organic enrichment and benthic fauna–Some ecological consideration.
(NISCAIR, 2014)In the present study, synoptic data on the structure of macroinfauna and total organic content of sediment collected from different sources were analyzed to look for patterns of association consistent with conceptual model ... -
Organic matter - A key factor in controlling mercury distribution in estuarine sediment
(Elsevier, 2015)Organic matter (OM) was found to play an important role in controlling mercury (Hg) distribution and speciation in estuarine sediment of the Vembanad Lake. The sedimentary organic carbon (OC) from the northern part of the ... -
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 ... -
Organic matter distribution in the continental shelf sediments, off Kochi, west coast of India
(Indian Petroleum Publishers, 2003)Organic matter was analysed on the silt-clay fraction of forty eight sediment samples from the continental shelf off Kochi, west coast of India. It was found to be high in the recent, near shore silt-clay predominant ... -
Organic Nutrients Support High Primary Production in the Bay of Bengal
(2019)The Bay of Bengal (BoB) is known to experience low productivity but high sinking carbon fluxes to the bottom, and this paradox is attributed to mineral ballast of organic matter. We found for the first time that primary ... -
