Evidence of active dinitrogen fixation in surface waters of the eastern tropical South Pacific during El Niño and La Niña events and evaluation of its potential nutrient controls (2013, background): “…denitrification and anammox also occur [Castro-González et al., 2005; Hamersley et al., 2007; Lam et al., 2009], creating an N deficit compared to P, which has been predicted to create favorable biogeochemical conditions for N2 fixation in overlying euphotic zone waters [Deutsch et al., 2007].”
Revising the nitrogen cycle in the Peruvian oxygen minimum zone (2009, background): “Alternatively, remineralized NH4 might come from preferential degradation of organic nitrogen over carbon in suboxic settings (25), or the remineralization of nitrogen-enriched organic matter might result from the spatially coupled N2 fixation over the OMZ (26, 27).”
Nitrogen fixation by unicellular diazotrophic cyanobacteria in the temperate oligotrophic North Pacific Ocean (2007, background): “…that (1) the magnitude of marine N2 fixation may be substantially higher than current measurements predict (Codispoti 2006) and (2) large regions of the Pacific Ocean outside of the subtropics are responsible for the missing marine N2 fixation component (Codispoti 2006; Deutsch et al. 2007).”
Nitrogen isotopic baselines and implications for estimating foraging habitat and trophic position of yellowfin tuna in the Indian and Pacific Oceans (2015, background): “Nitrogen with low δN values from N2 fixation near Reunion Island and south of Madagascar also contributes to this gradient (Deutch et al., 2007; Poulton et al., 2009).”
Ammonium regeneration and nitrification rates in the oligotrophic Atlantic Ocean: Implications for new production estimates (2008, background): “The new production paradigm is further complicated by new insights into the impact of N2 fixation on the marine N cycle (Deutsch et al. 2007).”
Evidence for efficient regenerated production and dinitrogen fixation in nitrogen-deficient waters of the South Pacific Ocean: impact on new and export production estimates (2008, methodology): “In this context, the BIOSOPE (BIOgeochemistry and Optics South Pacific Experiment) cruise was scheduled to provide a complete data set of biogeochemical parameters in the South Pacific Ocean, characterized by a marked nitrogen-deficiency (Deutsch et al., 2007; Raimbault et al., 2007).”
Iron, phosphorus, and nitrogen supply ratios define the biogeography of nitrogen fixation (2013, background): “Sensitivity to plankton stoichiometry—As is the case for diagnostics of nitrogen fixation based on the divergence of P* (Deutsch et al. 2007; Mills and Arrigo 2010), the definition of the six provinces is somewhat sensitive to the average elemental stoichiometry of the nondiazotroph community (Eqs.”
An Earth-system perspective of the global nitrogen cycle (2008, background): “Although many hypotheses have been put forward, current evidence suggests that the marine phosphorus cycle is crucial in stabilizing the marine nitrogen cycl”
Diversity and activity of nitrogen‐fixing communities across ocean basins (2017, background): “…to moderate rates we measured add to the mounting evidence that ESP waters are unlikely to harbor the high NFR predicted by initial model projections (Deutsch et al. 2007), perhaps because iron limitation precludes extensive diazotrophy in this region (Weber and Deutsch 2014; Knapp et al. 2016).”
