Excess nitrogen as a marker of intense dinitrogen fixation in the Western Tropical South Pacific Ocean: impact on the thermocline waters of the South Pacific

, 2018
. As part of the Oligotrophy to UlTra-oligotrophy PACific Experiment cruise, which took place in the Western Tropical South Pacific during the austral summer (March–April 2015), we present data on nitrate, phosphate and on particulate and dissolved organic

Diazotrophic community and associated dinitrogen fixation within the temperate coral Oculina patagonica

Environmental Microbiology, 2018
Dinitrogen (N2 ) fixing bacteria (diazotrophs) are an important source of new nitrogen in oligotrophic environments and represent stable members of the microbiome in tropical corals, while information on corals from temperate oligotrophic regions is ...

Global Carbon Investment in Terrestrial Biological Nitrogen Fixation

Global Biogeochemical Cycles, Volume 40, Issue 8, August 2026.
Abstract Biological nitrogen (N) fixation (BNF) provides the N needed to produce proteins and other biological building blocks, helping feed humanity and mitigate climate change. Due to its high energetic cost compared to other forms of N acquisition, biotic investment in BNF indicates N limitation. Globally gridded BNF flux data provide an opportunity

Heterogeneity of nitrogen fixation in the mesopelagic zone of the South China Sea

Frontiers in Marine Science
Biological dinitrogen (N2) fixation, the energetically expensive conversion of N2 gas to ammonia, plays an essential role in balancing the nitrogen budget in the ocean.

Nutrient limitation of primary productivity in the Southeast Pacific (BIOSOPE cruise) [PDF]

Biogeosciences, 2008
Iron is an essential nutrient involved in a variety of biological processes in the ocean, including photosynthesis, respiration and dinitrogen fixation. Atmospheric deposition of aerosols is recognized as the main source of iron for the surface ocean. In

Diazotrophy in the Indian Ocean: Current understanding and future perspectives

Limnology and Oceanography Letters, 2023
Dinitrogen (N2) fixation provides the major source of reactive nitrogen in the open ocean, sustaining biological productivity. The Indian Ocean (IO) covers 22% of the ocean surface, while it only represents 1% of the global diazotroph database.

Three Decades of Soil N2O Research—Insights and Gaps

Global Change Biology, Volume 32, Issue 8, August 2026.
Progress in N2O Research and Key Breakthroughs and Transitions from 1990 to 2025 across three domains: (A) process understanding, (B) microbial ecology, and (C) modelling of soil N2O emissions. ABSTRACT Nitrous oxide (N2O) is a potent greenhouse gas (GHG) whose atmospheric concentration continues to rise, largely driven by nitrogen (N) inputs to ...

N2 Fixation in the Eastern Arabian Sea: Probable Role of Heterotrophic Diazotrophs

Frontiers in Marine Science, 2017
Biogeochemical implications of global imbalance between the rates of marine dinitrogen (N2) fixation and denitrification have spurred us to understand the former process in the Arabian Sea, which contributes considerably to the global nitrogen budget ...

Boron-Doped Graphene Catalyzes Dinitrogen Fixation with Electricity

Chem, 2018
The development of catalysts for electrochemical dinitrogen reduction has so far focused on metal-based compounds and materials. In a recent report published in Joule, Zheng and colleagues demonstrated that boron-doped graphene electrochemically reduces ...
