    • An interactive end-user software application for a deep-sea photographic database 

      Jaisankar, S.; Sharma, R. (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 ...
    • Detailed bathymetric surveys in the central Indian Basin 

      Kodagali, V.N.; KameshRaju, K.A.; Ramprasad, T.; George, P.; Jaisankar, S. (International Hydrographic Bureau, France, 1992)
      Over 420,000 line kilometers of echo-sounding data was collected in the Central Indian Basin. This data was digitized, merged with navigation data and a detailed bathymetric map of the Basin was prepared. The Basin can be ...
    • Image analysis of seafloor photographs for estimation of deep-sea minerals 

      Sharma, R.; Jaisankar, S.; Samanta, S.; Sardar, A.A.; Gracias, D.G. (Springer, 2010)
      Factors such as non-uniform illumination of seafloor photographs and partial burial of polymetallic nodules and crusts under sediments have prevented the development of a fully automatic system for evaluating the distribution ...
    • Impacts on surface productivity during sediment dispersal experiment in Central Indian Basin 

      LokaBharathi, P.A.; Nath, B.N.; Ingole, B.S.; Parthiban, G.; Matondkar, S.G.P.; Raghukumar, C.; Khadge, N.H.; Valsangkar, A.B.; Suryanarayana, A.; Jaisankar, S.; Sharma, R. (Taylor and Francis, 2005)
      It is anticipated that in the case of mining of marine minerals, sea floor sediments will be brought up along with the mineral ores and discharged on the surface. These nutrient rich sediments would create a set of different ...
    • Integration of deeptow data for mapping of deepsea resources 

      Sharma, R.; Jaisankar, S.; Sudhakar, M.; Ramprasad, T. (Int. Soc. Offshore and Polar Eng., Japan, 1995)
      Deeptowed photographic and acoustic surveys in the Pioneer Area in Central Indian Basin, resulted in collection of 52,295 photographs, 450 hours of video record and 1129 km of sub-bottom and side scan data. Data-processing ...
    • Manganese nodule morphology as indicators for oceanic processes in the Central Indian Basin 

      Vineesh, T.C.; Nath, B.N.; Banerjee, R.; Jaisankar, S.; Lekshmi, V. (Taylor & Francis, 2009)
      In order to understand the role of geological features in the depositional environment and the prevailing oceanic processes on the formation and characteristics of manganese nodules, a detailed morphological study of the ...
    • Monitoring the impact of simulated deep-sea mining in Central Indian Basin 

      Sharma, R.; Nath, B.N.; Jaisankar, S. (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 ...
    • Mossbauer spectroscopy and x-ray diffraction studies of ferromanganese nodules from central Indian ocean basin 

      Ganwani, G.; Bhatia, B.; Jaisankar, S.; Pattan, J.N.; Dixit, A.; Tripathi, R.P. (Indian Society of Applied Geochemists, 2017)
      We report room temperature 57Fe Mossbauer spectroscopic and powder X-ray diffraction studies carried out on Fe-Mn nodules collected from the Central Indian Ocean Basin, to understand the oxidation state of Iron. Mossbauer ...
    • Trace elements in ferromanganese nodules from the central indian ocean basin 

      Pattan, J.N.; Parthiban, G.; Amonkar, A.; Shaikh, S.A.; Jaisankar, S. (Taylor & Francis, 2017)
      Thirty-three bulk ferromanganese nodules from the sediment-water interface of siliceous sediment domain from the Central Indian Ocean Basin were analyzed for 50 elements including 6 new (Be, As, Se, Sn, Sb, and Bi) using ...
