    Controls on greigite preservation in a gas hydrate system of the Krishna-Godavari basin, Bay of Bengal 

    Badesab, F.K.; Gaikwad, V.; Dewangan, P. (Springer Verlag, 2020)
    Shallow sediments across large parts of Krishna-Godavari (K-G) basin offshore east central Indian contain abundant methane and gas hydrates. In this study, we carried out rock-magnetic and transmission electron microscope ...

    Contrasting sulfidization in the turbidite and hemipelagic sediments of Bengal Fan 

    Volvoikar, S.P.; Mazumdar, A.; Peketi, A.; Dewangan, P.; Sawant, B.; Manaskanya, A.; Goswami, H.; Das, D.; Pujari, S. (Elsevier Ltd, 2020)
    We report for the first time, contrasting sulfidization profiles in a sedimentary sequence comprising of clay-silt turbidites and hemipelagic dominated deposits in a channel-levee complex of the middle Bengal Fan. The ...

    Strike-slip seismicity at the Andaman-Sumatra Subduction Zone: Role of the fracture zones and age of the subducting lithosphere 

    Jacob, J.; Dyment, J.; Ghosal, D.; Dewangan, P. (Elsevier, 2021)
    A better comprehension of the shallow strike-slip seismicity along the Sunda Trench is achieved by superimposing the Wharton basin fracture zones, magnetic isochrones, and focal mechanisms to the geometry of the subducting ...

    Possible Linkages between Microseisms in the Andaman?Nicobar Region and Swells in the South Indian Ocean 

    Reddy, T.R.; Dewangan, P.; Bhaskaran, P.K.; Roy, P.N.S. (Seismological Society of America, 2021)
    Microseism source characterization and its genesis play a key role in linking microseism records to prevailing atmospheric and oceanic conditions. In the present study, we analyzed the spatial and temporal distribution of ...

    Magnetic Mineral Diagenesis in a Newly Discovered Active Cold Seep Site in the Bay of Bengal 

    Badesab, F.K.; Dewangan, P.; Gaikwad, V. (Frontiers Media SA, 2020)
    Diagenetically formed magnetic minerals at marine methane seep sites are potential archive of past fluid flow and could provide important constraints on the evolution of past methane seepage dynamics and gas hydrate formation ...

    Sub-surface magma movement inferred from low-frequency seismic events in the off-Nicobar region, Andaman Sea 

    Aswini, K.K.; Dewangan, P.; KameshRaju, K.A.; Yatheesh, V.; Singha, P.; Arya, L.; Reddy, T.R. (Nature Publishing Group, 2020)
    Monitoring volcanic activity along the submarine volcanoes that are usually induced by subsurface magmatism is a challenge. We present fresh set of Ocean Bottom Seismometer (OBS) data that shows geophysical evidence ...

    Diagenesis of Magnetic Minerals in Active/Relict Methane Seep: Constraints From Rock Magnetism and Mineralogical Records From Bay of Bengal 

    Gaikwad, V.; Badesab, F.K.; Dewangan, P.; Kotha, M. (Frontiers Media�, 2021)
    In this study, we conducted a comprehensive investigation of rock magnetic, mineralogical, and sedimentological records of sediment cores supplemented by a high resolution seismic data to elucidate the controls of structural ...

    Seismotectonic evaluation of off Nicobar earthquake swarms, Andaman Sea 

    Aswini, K.K.; KameshRaju, K.A.; Dewangan, P.; Yatheesh, V.; Singha, P.; Reddy, T.R. (Elsevier, 2021)
    The Andaman Sea has experienced a number of earthquake swarms as a result of complex tectonics arising from oblique subduction, active volcanic arc, the backarc spreading center, and sliver fault systems. One of the most ...

    Velocity modeling and attribute analysis to understand the gas hydrates and free gas system in the Mannar Basin, India 

    Mishra, C.K.; Dewangan, P.; Mukhopadhyay, R.; Banerjee, D. (Elsevier, 2021)
    The Mannar basin, located between India and Sri Lanka, is poorly explored for hydrocarbon compared to other petroliferous basins in the Indian offshore. 2D multichannel seismic data was acquired onboard R/V Samudra Ratnakar ...

    Morphotectonic signatures and revised timing of opening of the Andaman Backarc Basin, Northeast Indian Ocean 

    Yatheesh, V.; Aswini, K.K.; KameshRaju, K.A.; Savio, J.J.; Gawas, Amol; Dewangan, P. (Elsevier, 2021)
    The Andaman Backarc Basin is believed to have been formed by the present episode of seafloor spreading in the Andaman Sea, separating the Alcock Rise in the north (Burmese Plate) and the Sewell Rise in the south (Sunda ...
