    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 ...

    Variability of dissolved oxygen in the Arabian Sea Oxygen Minimum Zone and its driving mechanisms 

    Shenoy, D.M.; Suresh, I.; Uskaikar, H.; Kurian, S.; Vidya, P.J.; Shirodkar, G.; Gauns, M.; Naqvi, S.W.A. (2020)
    The Arabian Sea hosts one of the most intense, perennial Oxygen Minimum Zones (OMZ) in the world ocean. Observations along a meridional transect at 68°E extending from 8 to 21°N showed large seasonal as well as interannual ...

    Dissolved and particulate iron redox speciation during the LOHAFEX fertilization experiment 

    Laglera, L.M.; Naik, H.; Klaas, C.; Naqvi, S.W.A.; Wolf-Gladrow, D.A.; Tovar-Sanchez, A. (Elsevier, 2022)
    The redox speciation of iron was determined during the iron fertilization LOHAFEX and for the first time, the chemiluminescence assay of filtered and unfiltered samples was systematically compared.We hypothesize that higher ...

    Chemolithoautotrophic denitrification intensifies nitrogen loss in the Eastern Arabian Sea Shelf waters during sulphidic events 

    Pratihary, A.K.; Lavik, G.; Naqvi, S.W.A.; Shirodkar, G.; Sarkar, Amit; Marchant, H.; Ohde, T.; Shenoy, D.M.; Kurian, S.; Uskaikar, H.; Kuypers, M.M.M. (Elsevier, 2023)
    The Eastern Arabian Sea Shelf i.e. Western Indian Continental Shelf (WICS) – a known biogeochemical hotspot is characterized by monsoonal upwelling, seasonal O2 deficiency, extremely high N2O build-up and sulphidic events. ...

    The relationship between volatile halocarbons and phytoplankton pigments during a Trichodesmium bloom in the coastal eastern Arabian Sea 

    Roy, R.; Pratihary, A.K.; Shirodkar, G.; Mochemadkar, S.; Gauns, M.; Naqvi, S.W.A. (Elsevier, 2011)
    Eukaryotic phytoplankton such as diatoms and prymnesiophytes produce biogenic halocarbons in the ocean that serve as important sources of chlorine and bromine to the atmosphere, but the role of cyanobacteria in halocarbon ...

    Dissolved methane in Indian freshwater reservoirs 

    Shirodkar, G.; Naqvi, S.W.A.; Kurian, S.; Shenoy, D.M.; Pratihary, A.K.; Naik, H.; Patil, S.; Sarkar, A.; Gauns, M. (Springer, 2013)
    Emission of methane (CH4), a potent greenhouse gas, from tropical reservoirs is of interest because such reservoirs experience conducive conditions for CH4 production through anaerobic microbial activities. It has been ...

    Seasonally varying biogeochemical regime around the coral habitats off central west coast of India 

    Shirodkar, G.; Naik, H.; Naqvi, S.W.A.; Pratihary, A.K.; Hussain, A.; Shenoy, D.M.; Gauns, M.; Manikandan, B.; Manjrekar, S.; Patil, Anagha (Elsevier, 2024)
    The Western Indian Continental Shelf (WICS) experiences upwelling during the Southwest Monsoon (SWM), leading to deoxygenation and acidification of subsurface waters. The region has patchy growth of corals, e.g. in the ...
