Buried nodules from the central Indian Ocean basin
(Regional Research laboratory, Bhubaneswar, 2005)The occurrence of buried nodules is rare compared to surface nodule abundance in the deep sea. Surface nodules are collected with freefall grab, vanveen /peterson grabs, dredges and sediment cores whereas buried nodules ... -
Monitoring the impact of simulated deep-sea mining in Central Indian Basin
(Taylor and Francis, 2005)Monitoring of deep-sea disturbances, natural or man-made, has gained significance due to the associated sediment transport and for the ensuing alterations in environmental conditions. During the Indian Deep-sea Environment ... -
The beach ridges of India: A review
(Coastal Education and Research Foundation, 2005)An attempt has been made to assemble and synthesize research work conducted on beach ridges and associated geomorphic features around India. Information on location, morphology, origin, and age of beach ridges, has been ... -
Performance evaluation of Honeywell silicon piezoresistive pressure transducers for oceanographic and limnological measurements

Ocean wave parameters estimation using backpropagation neural networks
(Elsevier, 2005)In the present study, various ocean wave parameters are estimated from theoretical Pierson-Moskowitz spectra as well as measured ocean wave spectra using back propagation neural networks (BNN). Ocean wave parameters ... -
Echo-waveform classification using model and model free techniques: Experimental study results from central western continental shelf of India
(Marine Technology Society, 2005)Seafloor classifications and characterization using acoustic backscatter data from the central western continental shelf of India is presented in this work. Single beam sea-floor echo data using two frequencies: 33 kHz and ... -
An interactive end-user software application for a deep-sea photographic database
(Elsevier, 2005)A photographic database is created for cataloguing data from underwater deep-tow photographic surveys conducted in the Central Indian Ocean Basin. This includes digitizing, encoding and merging different types of data and ... -
Application of ground penetrating radar in placer mineral exploration for mapping subsurface sand layers: A case study
(Allied, India, 2005)Owing to the limitations of the existing conventional methods for mapping subsurface sedimentary layers, Geophysical methods especially GPR (Ground Penetrating Radar) techniques are widely being used. For the present study, ... -
