Bathymetric highs in the mid-slope region of the western continental margin of India - Structure and mode of origin
(Elsevier, 2010)Analysis of the multi- and single beam bathymetric, seismic, magnetic and free-air gravity (ship-borne and satellite derived) data from the western continental margin of India between 12 degrees 40 minutes N and 15 degrees ... -
Crustal structure and tectonics of the Ninetyeast Ridge from seismic and gravity studies
(American Geophysical Union, 2001)Seismic reflection and refraction, gravity, and bathymetric data across and along the central part of the Ninetyeast Ridge were analyzed to determine the crustal structure of the ridge and to understand its tectonics. The ... -
Delineation of structural lineaments from marine magnetic anomalies off Jonnalakonda, East Coast of India
(NISCAIR, New Delhi, 1991)Bathymetric and total magnetic intensity data off Jonnalakonda, south of Visakhapatnam, India have been collected. Magnetic anomaly contour map revealed that (1) the well developed magnetic anomaly occurring seaward side ... -
Geophysical studies over a segment of the Carlsberg Ridge, Indian Ocean
(Elsevier, 1993)The study of magnetic, gravity and bathymetric data over a segment of Carlsberg Ridge between 3 degrees and 4 degrees N lat., and 63 degrees 30' and 64 degrees 30'E long. revealed the presence of a prominent 57 degrees W ... -
Influence of bathymetry in manganese nodule pilot mine site selection: A case study from the Central Indian Basin
(Int. Soc. of Offshore and Polar-Eng.(ISOPE), Colorado, USA, 1995)Although manganese nodules are observed in all world oceans, known reserves cannot be only criterion in future mine sites selection and sizing. Detailed and accurate depth data is another major prerequisite. With the advent ... -
Influence of sedimentation on the geomorphology of the northwestern continental margin of India
(Taylor and Francis, 2000)Based upon the analysis of about 10,000 line km of echosounding and bathymetric data and variations in mass accumulation rate along the NW continental margin of India (between Kori creek and Mumbai), which has deduced in ... -
Isostatic response of the Laccadive Ridge from admittance analysis of gravity and bathymetry data
(Elsevier, 2008)The Laccadive Ridge (L-R), trending roughly parallel to the west coast of India, is an intriguing segmentof the northernmost Chagos-Laccadive Ridge (C-L-R) system. Although crustal nature and isostatic response of the ... -
Late Quaternary seismic sequence stratigraphy of the Gulf of Kachchh, northwest of India
(Coastal Education and Reserch Foundation, 2009)High-resolution seismic reflection and bathymetric data in 10 to 50 m water depth in the Gulf of Kachchh, northwest of India, have been analysed together with earlier results from the area. They have revealed geomorphic ... -
Magnetic basement in the central Bay of Bengal
(Kluwer, 2002)Analyses of about 6000 km of processed magnetic data in the central Bay of Bengal using Analytical Signal Processing and Werner Deconvolution techniques revealed that the depth to top of the magnetic basement varies between ... -
Model simulation of tide-induced currents in Gauthami-Godavari estuary
(Current Science Association, 2013)Predictive spatial distribution of flow field has been simulated from the time series data on currents and tides during dry season (11-19, February, 2009) in the Gauthami-Godavari Estuary utilizing TIDAL model. A 2D-Tidal ... -
Monitoring effects of simulated disturbance at INDEX site: Current status and future activities
(International Society of Offshore and Polar Engineers, 2003)During the Indian Deep-Sea Environment Experiment (INDEX), greater than 6000 cu.m of sediment was resuspended 5 m above seafloor. Data collected from deep-towed photography, sediment traps, sediment coring and CTD operations ... -
Multi-beam backscatter image data processing techniques employed to EM 1002 system
(CUSAT, 2009)Application of multi-beam bathymetric data provides interesting seafloor features. Besides obtaining bathymetric data for seabed characterization backscatter data is also important. However, use of raw multi-beam backscatter ... -
