    • Distribution of Urea in the Waters of the West Coast of India 

      Verlecar, X.N. (CSIR-NISCAIR, 1980)
      Urea concentrations at the surface are high both in coastal and offshore waters in the region north of 15 degrees N (0.3-7.76 mu g at N/litre) and low in the region south of this latitude (0-1.5 mu g at N/litre). Vertical ...
    • Effect of temperature on 'N' uptake of Chaetomorpha linum (Muller) and Padina tetrastomatica (Hauck) 

      Raikar, V.; Wafar, M.V.M. (ENVIS, India, 2006)
      Macroalgal species (Chaetomorpha linum and Padina tetrastomatica) collected from the Kavaratti lagoon (lat. 10 deg. 33 min. 16 sec. N and long. 72 deg. 38 min. 34 sec E) were brought to the laboratory and cleaned with ...
    • Experimental studies on Urea Degradation in Seawater 

      Rajendran, A.; Joseph, T.; Reddy, C.V.G. (Indian Association for Limnology and Oceanography, 1980)
      The rate of urea degradation in seawater was studied under various conditions and the kinetics of urea degradation was evaluated. Urea decomposition experiments showed that the rates and quantity of ammonium oxidation were ...
    • Nitrogen uptake kinetics of freshly isolated zooxanthellae 

      Wafar, M.V.M.; Wafar, S.; Rajkumar, R. (NISCAIR, New Delhi, 1993)
      Zooxanthellae freshly isolated from the coral host Pocillopora damicornis exhibited substrate-saturable uptake kinetics for ammonium, nitrate and urea. Maximum uptake velocity for ammonium [10.1 nmol. ( mu chl-a)./1h/1] ...
    • Nitrogenous nutrients and primary production in a tropical oceanic environment 

      Wafar, M.V.M.; Wafar, S.; Devassy, V.P. (Rosenstiel School of Marine and Atmospheric Science of the University of Miami, 1986)
      Measurements of the concentrations of nitrogenous nutrients and primary production were made at 10 stations along 8 degrees N and 10 degrees N in the tropical oceanic Lakshadweep waters Inorganic nitrogen (NO3, NO2 and ...
    • Urea as nitrogen source for phytoplankton production in coastal waters of Goa 

      Verlecar, X.N. (CSIR-NISCAIR, 1985)
      Annual variation of urea in coastal waters off Goa, India is 0 to 2.92 mu g-at N.1/1 and 0 to 4.69 mu g-at N.1/1 in adjacent estuarine waters of Mandovi. Peaks of phytoplankton production accompanied with the decrease in ...
