Development of the negative gravity anomaly of the 85 degrees E Ridge, northeastern Indian Ocean – A process oriented modelling approach
Sreejith, K.M.; Radhakrishna, M.; Krishna, K.S.; Majumdar, T.J. (Indian Academy of Sciences, 2011)The 85 degrees E Ridge is associated with two contrasting gravity anomalies: negative anomaly over the north part (up to 5 degrees N latitude), where the ridge structure is buried under thick Bengal Fan sediments and ... -
Geoid and gravity anomaly data of conjugate regions of Bay of Bengal and Enderby Basin: New constraints on breakup and early spreading history between India and Antarctica
Krishna, K.S.; Michael, L.; Bhattacharyya, R.; Majumdar, T.J. (American Geophysical Union, 2009)Timing of breakup of the Indian continent from eastern Gondwanaland and evolution of the lithosphere in the Bay of Bengal still remain as ambiguous issues. Geoid and free-air gravity data of Bay of Bengal and Enderby Basin ... -
High-resolution residual geoid and gravity anomaly data of the northern Indian Ocean - An input to geological understanding
Sreejith, K.M.; Rajesh, S.; Majumdar, T.J.; Rao, G.S.; Radhakrishna, M.; Krishna, K.S.; Rajawat, A.S. (Elsevier, 2013)Geoid data are more sensitive to density distributions deep within the Earth, thus the data are useful for studying the internal processes of the Earth leading to formation of geological structures. A much improved version ... -
Lithospheric stretching and the long wavelength free-air gravity anomaly of the Eastern Continental margin of India and the 85 degree E Ridge, Bay of Bengal
Rajesh, S.; Majumdar, T.J.; Krishna, K.S. (CSIR-NISCAIR, 2015)Among the submarine ridge systems in the northern Indian Ocean, the 85 degree E Ridge in the Bay of Bengal is more enigmatic owing to its peculiar anomalous negative free-air gravity. In general, this has been attributed ... -
Mapping of sea bottom topography over western offshore, India using TOPEX/ERS-1 altimeter data
Mohanty, K.K.; Majumdar, T.J.; Kunte, P.D.; Srivastava, A.K. (Elsevier, 1997)As bathymetry and geoid are highly correlated in the 50-300 km range, the satellite-derived geoid can be used in the mapping of bathymetry. An attempt has been made to assess the accuracy of predicting sea bottom ... -
Utilization of high resolution satellite geoid data for estimation of lithospheric thickness in the Bay of Bengal
Majumdar, T.J.; Bhattacharyya, R.; Chatterjee, S.; Krishna, K.S. (NISCAIR, CSIR, 2009)Very high-resolution database generated from Seasat, Geosat GM, ERS-1 and TOPEX/ POSEIDON altimeters data of the northern Indian Ocean has been used for the first time for preparation of geoid and free-air gravity maps. ... -
Validation of ERS-1 and high-resolution satellite gravity with in-situ shipborne gravity over the Indian offshore regions: Accuracies and implications to subsurface modeling
Chatterjee, S.; Bhattacharyya, R.; Michael, L.; Krishna, K.S.; Majumdar, T.J. (Taylor & Francis, 2007)Geoid and gravity anomalies derived from satellite altimetry are gradually gaining importance in marine geoscientific investigations. Keeping this in mind, we have validated ERS-1 (168 day repeat) altimeter data and very ...
