    • Induction of gynogenetic haploidy in oyster Crassostrea gigas, using ultra violet irradiated sperms 

      Goswami, U. (NISCAIR, New Delhi, 1993)
      Eggs of Crassostrea gigas were fertilized with sperms exposed to different doses of UV irradiations by keeping a constant rate of 121.47 ergs. mm/2 sec/1 and changing the period of exposure from 4 to 90 sec. Samples of ...

    • Spectral variations of UV-A and PAR solar radiation in estuarine waters of Goa 

      Talaulikar, M.; Suresh, T.; Silveira, N.; Desa, E.; Matondkar, S.G.P.; Lotlikar, A. (IEEE, 2011)
      The spectral solar radiation measurements in the range 350-800 nm were carried out in the estuarine waters of Goa using hyperspectral radiometer. The results of the analysis of solar light in the spectral range of ...

    • UV radiation and primary production in the Antarctic waters 

      LokaBharathi, P.A.; Krishnakumari, L.; Bhattathiri, P.M.A.; Chandramohan, D. (Department of Ocean Development, New Delhi, 1997)
      A profiling underwater radiometer was used for the first time in the waters around Indian Antarctic Station (70 degrees 46 minutes S and 11 degrees 44 minutes E) in the summer of 1994. The profiles include natural fluorescence ...

    • UV-absorbing bacteria in coral mucus and their response to simulated temperature elevations 

      Ravindran, J.; Kannapiran, E.; Manikandan, B.; Francis, K.; Arora, S.; Karunya, E.; AmitKumar; Singh, SanjayKumar; Jose, J. (Springer, 2013)
      Reef-building corals encompass various strategies to defend against harmful ultraviolet (UV) radiation. Coral mucus contains UV-absorbing compounds and has rich prokaryotic diversity associated with it. In this study, we ...
