    • A temperature profiler 

      Peshwe, V.B.; Desa, E. (Publ. and Inf. Dir., New Delhi, India, 1994)
      An instrument developed for measuring temperature profiles at sea in depth or time scales is described. PC-based programming offers flexibility in setting up the instrument for the mode of operation prior to each cast. A ...
    • Comparison of wind data from QuikSCAT and buoys in the Indian Ocean 

      Satheesan, K.; Sarkar, A.; Parekh, A.; RameshKumar, M.R.; Kuroda, Y. (Taylor and Francis, 2007)
      The performance of QuikSCAT-derived wind vectors is evaluated using in-situ data from moored buoys over the Indian Ocean. The results show that the mean differences for wind speed and wind direction are 0.37 ms sup(-1) and ...
    • Development of drifting buoys 

      Nayak, M.R.; Peshwe, V.B.; Tengali, S. (Publ. and Inf. Dir., New Delhi, India, 1994)
      Polar orbiting satellites equipped with random access data collection and position fixing systems have made long-term remote oceanographic/meteorological observations possible by means of instrumented drifting buoys fitted ...

    • Evaluation of pressure transducers under turbid natural waters 

      Joseph, A.; Desa, E.; Desa, E.; Smith, D.; Peshwe, V.B.; Vijaykumar, K.; Desa, J.A.E. (American Meteorological Society, 1999)
      Pressure measurements made in two turbid natural waters have led to the inference that the effective depthmean in situ density values, rho sub(eff), of these waters are less than (approx equal to 0.4%-4.5%) that of the ...
    • On the efficacy of indigenous method employed along Goa coast for protecting fishing craft against bio-deterioration 

      Santhakumaran, L.N.; UdayaBhaskar, S.; Wagh, A.B.; Rao, T.S.S. (Indian Association for Limnology and Oceanography, 1982)
      An indigenous formulation, comprising 'chandrus' and lime in Karanjel oil, used by the fishermen of Goa to protect their boats from marine wood-borers and foulers has been described Results of experiments using wooden test ...
    • Performance evaluation of Honeywell silicon piezoresistive pressure transducers for oceanographic and limnological measurements 

      Vijaykumar, K.; Joseph, A.; Desai, R.G.P.; Prabhudesai, S.P.; Nagvekar, S.; Damodaran, V. (American Meteorological Society, 2005)
