    • A preliminary study of anaerobic thiosulfate-oxidising bacteria as denitrifiers in the Arabian Sea 

      LokaBharathi, P.A.; Chandramohan, D.; Nair, S. (Taylor & Francis, 1988)
      Bacteria which oxidize thiosulfate and reduce nitrate (TONRB) and bacteria which oxidize thiosulfate and denitrify (TODB) sampled at 5-, 100-, 200-and 300-m depths were enumerated in agar shake cultures by colony counting ...
    • Bacterial contribution to mitigation of iron and manganese in mangrove sediments 

      Krishnan, K.P.; Fernandes, S.O.; Chandan, G.S.; LokaBharathi, P.A. (Elsevier, 2007)
      The Mandovi and Chapora, (Goa, India) are two tropical estuaries lying in close geographic proximity on the west coast of India. Seasonal changes in down core variation of Fe, Mn and Total Organic Carbon (TOC) in the ...
    • Characterization of Porteresia coarctata beds along the Goa coast, India 

      Jagtap, T.G.; Bhosale, S.H.; Charulata, S. (Elsevier, 2006)
      Porteresia coarctata, forms an important constituent in the plant succession leading to formation of mangrove communities along the estuaries in India. Major beds along the Mandovi estuary of Goa were monitored for their ...
    • Denitrification in the Arabian Sea 

      Naqvi, S.W.A.; Noronha, R.J.; Reddy, C.V.G. (Elsevier, 1982)
      Estimates of the amount of denitrification in the Arabian Sea are inconsistent, and so two methods of calculations of 'original' nitrate concentrations used in earlier studies have been reviewed. Nitrite at intermediate ...
    • Diversity of nitrite reductase genes (nirS) in the denitrifying water column of the coastal Arabian Sea 

      Jayakumar, D.A.; Francis, C.A.; Naqvi, S.W.A.; Ward, B.B. (Inter-Research, 2004)
      Denitrification often occurs in the water column, underlying zones of intense productivity and decomposition in upwelling regions. In the denitrifying zone off the southwest coast of India, high concentrations of nitrite ...
    • Monsoonal variability in abiotic parameters in coastal waters off Trivandrum evokes press and pulse response in biotic variables 

      Subina, N.S.; Bhosle, S.; Nair, S.; LokaBharathi, P.A. (Centre for Ocean and Environmental Studies, New Delhi, 2012)
      Trivandrum Coast experiences coastal upwelling during south west monsoon, which is accompanied by abiotic changes in physio-chemical parameters. The resultant biotic responses could range from an instantaneous pulse to a ...
    • Nitrite maxima in the Northern Arabian Sea 

      Sankaranarayanan, V.N.; DeSousa, S.N.; Fondekar, S.P. (CSIR-NISCAIR, 1983)
      There are 2 nitrite maxima in the Northern Arabian Sea, one at the thermocline depth and the other at depths between 300 and 500 m. The 2nd maximum is more prominent in the northeastern part of the Arabian Sea. The 1st ...
    • Nutrients from the mangrove areas of Cochin backwaters 

      Sheeba, P.; Devi, K.S.; Sankaranarayanan, V.N. (Kerala Science Congress, 1996)
      Nutrient like ammonia, nitrite, nitrate and inorganic phosphate and some hydrographic parameters were estimated for one year from two distinct mangrove ecosystems of Cochin backwaters viz. Puduvypeen and Nettoor. The ammonia ...
    • Reduced iron associated with secondary nitrite maxima in the Arabian Sea 

      Moffetta, J.W.; Goepferta, T.J.; Naqvi, S.W.A. (Elsevier, 2007)
      Dissolved iron and Fe(II) were measured in the oxygen minimum zone (OMZ) of the Arabian Sea in September 2004. The OMZ is a well-demarcated feature characterized by high rates of denitrification, and a deep nitrite maximum ...
