Elevated turbidity and dissolved manganese in deep water column near 10�47�S Central Indian Ridge: studies on hydrothermal activities
Ray, D.; KameshRaju, K.A.; Rao, S.A.; SuryaPrakash, L.; Mudholkar, A.V.; Yatheesh, V.; Samudrala, K.; Kota, D. (Springer Science and Business Media Deutschland GmbH, 2020)The deep water in the ridge segment between 10°18'S and 10°57'S of northern Central Indian Ridge was surveyed with CTD and AUV for seafloor hydrothermal activities. During the survey, 25 CTD hydrocasts were made, and ... -
Gravity anomalies over the central Indian ridge between 3 degree S and 11 degree S, Indian Ocean: Segmentation and crustal structure
Samudrala, K.; KameshRaju, K.A.; RamaRao, P. (Indian Academy of Sciences, 2016)High-resolution shipboard geophysical investigations along the Indian Ocean ridge system are sparse especially over the Carlsberg and Central Indian ridges. In the present study, the shipboard gravity and multibeam bathymetry ... -
Megafaunal community structure of Andaman seamounts including the back-arc basin - A quantitative exploration from the Indian Ocean
Sautya, S.; Ingole, B.S.; Ray, D.; Stohr, S.; Samudrala, K.; KameshRaju, K.A.; Mudholkar, A.V. (Public Library of Science, 2011)Species rich benthic communities have been reported from some seamounts, predominantly from the Atlantic and Pacific Oceans, but the fauna and habitats on Indian Ocean seamounts are still poorly known. This study focuses ... -
Microbathymetry inferences from two AUV dives over a short segment of the Central Indian Ridge between 10�18' and 10�57'S, Indian Ocean
KameshRaju, K.A.; Yatheesh, V.; Rao, A.S.; SuryaPrakash, L.; Ray, D.; Mudholkar, A.; Samudrala, K.; Augustin, N.; Kurian, P.J. (Springer, 2023)The topographic fabric of the rift valley floor has been analyzed using the multibeam echosounder data obtained by the autonomous underwater vehicle (AUV) Abyss at two locations over a short segment of the slow-spreading ... -
Nature of the Ambient Noise, Site Response, and Orientation of Ocean?Bottom Seismometers (OBSs): Scientific Results of a Passive Seismic Experiment in the Andaman Sea
Dewangan, P.; Reddy, R.; KameshRaju, K.A.; Singha, P.; Aswini, K.K.; Yatheesh, V.; Samudrala, K.; Shuhail, M. (Seismological Society of America, 2018)We analyze the nature of the ambient noise and site response for ocean?bottom seismometers (OBSs) deployed in the Andaman region. The probabilistic power spectral densities of the OBSs show that the noise level in the ... -
Segmentation and morphology of the Central Indian Ridge between 3°S and 11°S, Indian Ocean
KameshRaju, K.A.; Samudrala, K.; Drolia, R.K.; Amarnath, D.; Ramachandran, R.; Mudholkar, A.V. (Elsevier, 2012)The segmentation pattern of 750 km long Central Indian Ridge (CIR) between 3 degrees S and 11 degrees S latitudes in the Indian Ocean has been studied using multibeam bathymetry and magnetic data. Twelve ridge segments ... -
Slow spreading ridges of the Indian Ocean: An overview of marine geophysical investigations
KameshRaju, K.A.; Mudholkar, A.V.; Samudrala, K. (Indian Geophysical Union, 2016)Sparse and non-availability of high resolution geophysical data hindered the delineation of accurate morphology, structural configuration, tectonism and spreading history of Carlsberg Ridge (CR) and Central Indian Ridges ... -
Tectonic and volcanic implications of a cratered seamount off Nicobar Island, Andaman Sea
KameshRaju, K.A.; Ray, D.; Mudholkar, A.V.; Murty, G.P.S.; Gahalaut, V.K.; Samudrala, K.; Paropkari, A.L.; Ramachandran, R.; SuryaPrakash, L. (Elsevier, 2012)The region of the Nicobar earthquake swarm of January 2005 has been explored during a recent cruise using multibeam swath bathymetry, seafloor imaging and TV-guided sampling to decipher the seafloor morphology, nature and ...
