    Aerobic microbial communities in the sediments of a marine oxygen minimum zone 

    Bhattacharya, S.; Roy, C.; Mandal, Subhrangshu; Sarkar, J.; Rameez, M.J.; Mondal, N.; Mapder, T.; Chatterjee, Sumit; Pyne, P.; Alam, M.; Haldar, P.K.; Roy, R.; Fernandes, S.; Peketi, A.; Chakraborty, R.; Mazumdar, A.; Ghosh, W. (Oxford University Press (OUP), 2020)
    The ecology of aerobic microorganisms is never explored in marine oxygen minimum zone (OMZ) sediments. Here we reveal aerobic bacterial communities along ~3�m sediment-horizons of the eastern Arabian Sea OMZ. Sulfide-containing ...

    Climatic and Tectonic Control on the Bengal Fan Sedimentation since the Pliocene 

    Peketi, A.; Mazumdar, A.; Pillutla, S.P.K.; Sawant, B.; Gupta, H. (AGU-Wiley, 2021)
    Strontium and Neodymium isotopic analysis of the lithogenic fractions of the hole U1445A (International Ocean Discovery Program-353) collected from the deep-water end of the Mahanadi basin (western Bay of Bengal) was carried ...

    Sulfidization processes in seasonally hypoxic shelf sediments: A study off the West coast of India 

    Fernandes, Svetlana; Mazumdar, A.; Peketi, A.; Anand, S.S.; Rengarajan, R.; Jose, A.; Manaskanya, A.; Carvalho, M.A.; Shetty, D. (Elsevier Ltd, 2020)
    Continental shelves are the major sites for organic carbon burial and sulfate reduction. Organic carbon degradation and sulfidization along continental shelves are expected to play a significant role in global carbon-sulfur-iron ...

    Bioactive Trace Elements' Composition and Their Fractional Solubility in Aerosols from the Arabian Sea during the Southwest Monsoon 

    Panda, P.P.; Aswini, M.A.; Bhatt, Poonam; Srimuruganandam, B.; Peketi, A.; Kumar, Ashwini (American Chemical Society, 2022)
    Atmospheric dust deposition supplies a significant amount of macro- and micronutrients to surface ocean water, thus playing a vital role in modulating phytoplankton growth.In this context, we measured soluble and total ...

    Biogeochemistry and trophic structure of a cold seep ecosystem, offshore Krishna-Godavari basin (east coast of India) 

    Peketi, A.; Mazumdar, A.; Sawant, B.; Manaskanya, A.; Zatale, Anjali (Elsevier, 2022)
    Active cold seep sites associated with shallow gas hydrates were recently reported from Krishna-Godavari (K-G) basin, off east coast of India. Benthic fauna including chemosymbiotic bivalves (genera Bathymodiolus, Acharax, ...
