Benthic exchange along a tropical estuarine salinity gradient during dry season: Biogeochemical and ecological implications
Pratihary, A.K.; Naik, Richita; Karapurkar, S.; Gauthankar, M.; Khandeparker, R.; Manjrekar, S.; Gauns, M. (Elsevier, 2021)Benthic biogeochemistry and its coupling with pelagic ecology are less understood in tropical than in temperate estuaries, which have significant implications for global carbon and nutrient cycling. In dry season, the ... -
Measurement of C and N isotopes of geological samples using Delta V Plus Stable Isotope Ratio Mass Spectrometer via different preparatory systems
Karapurkar, S.; Methar, A.; Agnihotri, R. (National Inst. of Oceanography (CSIR); India, 2008)Stable isotope studies have proven their unique potential in unraveling several key biogeochemical processes occurring on solid earth as well as in world oceans. In addition, measurements of stable isotopes of lighter ... -
Spatial and seasonal variations in the particulate sinking flux in the Bay of Bengal
Kurian, S.; Shenoy, D.M.; Akhil, V.P.; Kessarkar, P.M.; Gauns, M.; Shetye, S.S.; Kabeer, M.; Apsara, P.V.; Methar, A.; Karapurkar, S.; Chndrasekhararao, A.V.; Naqvi, S.W.A. (Elsevier, 2023)Sediment traps have been widely used to study particles sinking through the oceanic water column. As part of the SIBER-INDIA program, sediment traps were deployed at three depths ? 430 m (shallow), 1020 m (middle), and ... -
Stable carbon and nitrogen isotopic composition of bulk aerosols over India and northern Indian Ocean
Agnihotri, R.; Mandal, T.K.; Karapurkar, S.; Naja, M.; Gadi, R.; Ahammed, Y.N.; Kumar, A.; Saud, T.; Saxena, M. (Elsevier, 2011)Atmospheric carbonaceous aerosols of South Asian origin have received immense concerns in the Anthropocene owing to their plausible role in the observed regional to inter-continental scale climate anomalies. Tracking ... -
Variation of amino acid in the sinking particulates in the northeastern Arabian Sea and the northern Bay of Bengal
Apsara, P.V.; Kurian, S.; Joseph, D.; Megha, D.; Kankonkar, H.; Khandeparker, R.; Karapurkar, S.; Methar, A. (Elsevier, 2023)Sediment traps are widely used to get insight into how particulate matter forms and settles in the water column. Earlier studies in the Northern Indian Ocean have shown that the sinking flux depends mainly on surface primary ... -
Variations in some environmental characteristics including C and N stable isotopic composition of suspended organic matter in the Mandovi estuary
Maya, M.V.; Soares, M.A.; Agnihotri, R.; Pratihary, A.K.; Karapurkar, S.; Naik, H.; Naqvi, S.W.A. (Springer, 2011)Chemical and isotopic (delta sup(13)C and delta sup(15)N) investigation of the Mandovi estuary along the Indian west coast affected strongly by the seasonal monsoon cycle was carried out. The Mandovi estuary is a major ... -
