    • Glacial-interglacial modulation of the marine nitrogen cycle by high-latitude O2 supply to the global thermocline 

      Galbraith, Eric D.; Kienast, Markus; Pedersen, Thomas F.; Calvert, Stephen E. (American Geophysical Union, 2004-10-16)
      An analysis of sedimentary nitrogen isotope records compiled from widely distributed marine environments emphasizes the global synchrony of denitrification changes and provides evidence for a strong temporal coupling of ...
    • Modeling denitrification in aquatic sediments 

      Fennel, Katja; Brady, Damian; DiToro, Dominic; Fulweiler, Robinson W.; Gardner, Wayne S.; Giblin, Anne E.; McCarthy, Mark J.; Rao, Alexandra; Seitzinger, Sybil P.; Thouvenot-Korppoo, Marie; Tobias, Craig R. (2008-10-10)
      Sediment denitrification is a major pathway of fixed nitrogen loss from aquatic systems. Due to technical difficulties in measuring this process and its spatial and temporal variability, estimates of local, regional and ...
    • Potential importance of physiologically diverse benthic foraminifera in sedimentary nitrate storage and respiration 

      Bernhard, Joan M.; Casciotti, Karen L.; McIlvin, Matthew R.; Beaudoin, David J.; Visscher, Pieter T.; Edgcomb, Virginia P. (American Geophysical Union, 2012-07-03)
      Until recently, the process of denitrification (conversion of nitrate or nitrite to gaseous products) was thought to be performed exclusively by prokaryotes and fungi. The finding that foraminifera perform complete ...
