    • Chemolithoautotrophic denitrification intensifies nitrogen loss in the Eastern Arabian Sea Shelf waters during sulphidic events 

      Pratihary, A.K.; Lavik, G.; Naqvi, S.W.A.; Shirodkar, G.; Sarkar, Amit; Marchant, H.; Ohde, T.; Shenoy, D.M.; Kurian, S.; Uskaikar, H.; Kuypers, M.M.M. (Elsevier, 2023)
      The Eastern Arabian Sea Shelf i.e. Western Indian Continental Shelf (WICS) – a known biogeochemical hotspot is characterized by monsoonal upwelling, seasonal O2 deficiency, extremely high N2O build-up and sulphidic events. ...
    • Massive Nitrogen Loss Over the Western Indian Continental Shelf During Seasonal Anoxia: Evidence From Isotope Pairing Technique 

      Sarkar, Amit; Naqvi, S.W.A.; Lavik, G.; Pratihary, A.K.; Naik, H.; Shirodkar, G.; Kuypers, M.M.M. (Frontiers Media SA, 2020)
      The western Indian continental shelf houses the world's largest naturally formed coastal low-oxygen zone that develops seasonally during the summer monsoon. We investigated multiple reductive nitrogen transformation pathways ...
    • Methane stimulates massive nitrogen loss from freshwater reservoirs in India 

      Naqvi, S.W.A.; Lam, P.; Shirodkar, G.; Sarkar, Amit; Naik, H.; Pratihary, A.K.; Shenoy, D.M.; Gauns, M.; Kurian, S.; Damare, S.R.; Duret, M.; Lavik, G.; Kuypers, M.M.M. (Nature Publishing Group, 2018)
      The fate of the enormous amount of reactive nitrogen released to the environment by human activities in India is unknown. Here we show occurrence of seasonal stratification and generally low concentrations of dissolved ...
    • N2 production rates limited by nitrite availability in the Bay of Bengal oxygen minimum zone 

      Bristow, L.A.; Callbeck, C.M.; Larsen, M.; Altabet, M.A.; Dekaezemacker, J.; Forth, M.; Gauns, M.; Glud, R.N.; Kuypers, M.M.M.; Lavik, G.; Milucka, J.; Naqvi, S.W.A.; Pratihary, A.K.; Revsbech, N.P.; Thamdrup, B.; Treusch, A.H.; Canfield, D.E. (Macmillan Publishers Limited, 2017)
      A third or more of the fixed nitrogen lost from the oceans as N<sub>2</sub> is removed by anaerobic microbial processes in open ocean oxygen minimum zones. These zones have expanded over the past decades, and further ...
