Nutrient dynamics and coupling with biological processes and physical conditions in the Bohai Sea
- Environmental ScienceFrontiers in Marine Science
- 2022
The Bohai Sea is a habitat for economically important fish in China, but its ecological environment has changed significantly, and it is necessary to further clarify the dynamics and the internal…
Estimating Nitrogen and Phosphorus Cycles in a Timber Reef Deployment Area
- Environmental ScienceWater
- 2020
In an oligotrophic bay, Mitsu Bay, Japan, artificial timber reefs (ATRs) are deployed to increase fish production. In such man-made ecosystems, the biological activities of other organisms as well as…
Dynamic interaction between basin redox and the biogeochemical nitrogen cycle in an unconventional Proterozoic petroleum system
- Environmental Science, GeologyScientific Reports
- 2019
It is shown that cyclic enrichment of organic matter in the world’s oldest hydrocarbon play is not associated with flooding surfaces and is unrelated to variations in mineralogy or changes in the relative rate of clastic to biogenic sedimentation—factors typically attributed to organic enrichment in Phanerozoic shales.

Deposition of Aerosols onto Upper Ocean and Their Impacts on Marine Biota
- Environmental ScienceAtmosphere
- 2021
Atmospheric aerosol deposition (wet and dry) is an important source of macro and micronutrients (N, P, C, Si, and Fe) to the oceans. Most of the mass flux of air particles is made of fine mineral…
Macronutrients and dissolved iron in a land-ocean approach: Influences of contamination by ore tailings in Southeastern Brazil

Everything Is Everywhere: Physiological Responses of the Mediterranean Sea and Eastern Pacific Ocean Epiphyte Cobetia Sp. to Varying Nutrient Concentration
- Environmental ScienceMicrobial Ecology
- 2021
How ecological niches might determine, select, and modify the genomic and phenotypic features of the same bacterial species (i.e., Cobetia spp.) found in different marine environments is presented, pointing to a direct correlation between adaptability and oligotrophy of seawater.
Active reconfiguration of cytoplasmic lipid droplets governs migration of nutrient-limited phytoplankton
- Environmental SciencebioRxiv
- 2021
It is reported that storage and migration in phytoplankton are coupled traits, whereby motile species harness energy storing lipid droplets (LDs) to biomechanically regulate migration in nutrient limited settings.

Phytoplankton in the ocean use non-phosphorus lipids in response to phosphorus scarcity
- Environmental ScienceNature
- 2009
It is shown that phytoplankton, in regions of oligotrophic ocean where phosphate is scarce, reduce their cellular phosphorus requirements by substituting non-phosphorus membrane lipids for phospholipids, suggesting that phospholIPid substitutions are fundamental biochemical mechanisms that allow phy toplankon to maintain growth in the face of phosphorus limitation.
Database of diazotrophs in global ocean: abundance, biomass and nitrogen fixation rates
- Environmental Science
- 2012
This database is limited spatially, lacking large regions of the ocean especially in the Indian Ocean, but can nevertheless be used to study spatial and temporal distributions and variations of marine N2 fixation, to validate geochemical estimates and to parameterize and validate biogeochemical models.
Anaerobic ammonium oxidation by anammox bacteria in the Black Sea
- Environmental Science, BiologyNature
- 2003
Evidence for bacteria that anaerobically oxidize ammonium with nitrite to N2 in the world's largest anoxic basin, the Black Sea is provided and anammox bacteria have been identified and directly linked to the removal of fixed inorganic nitrogen in the environment.
Global patterns of marine nitrogen fixation and denitrification
- Environmental Science
- 1997
A new quasi‐conservative tracer N*, defined as a linear combination of nitrate and phosphate, is proposed to investigate the distribution of nitrogen fixation and denitrification in the world oceans.…
Iron fertilization enhanced net community production but not downward particle flux during the Southern Ocean iron fertilization experiment LOHAFEX
- Environmental ScienceGlobal Biogeochemical Cycles
- 2013
The data are consistent with the view that nitrate-rich but silicate-deficient waters are not poised for enhanced particle export upon iron addition, and attribute the lack of fertilization-induced export to silicon limitation of diatoms and reprocessing of sinking particles by detritus feeders.
Nitrogen cycling driven by organic matter export in the South Pacific oxygen minimum zone
- Environmental Science
- 2013
Oxygen minimum zones are expanding globally, and at present account for around 20–40% of oceanic nitrogen loss. Heterotrophic denitrification and anammox—anaerobic ammonium oxidation with nitrite—are…
Denitrification in marine sediments: A model study
- Environmental Science
- 1996
The rate and factors controlling denitrification in marine sediments have been investigated using a prognostic diagenetic model. The model is forced with observed carbon fluxes, bioturbation and…
The small unicellular diazotrophic symbiont, UCYN-A, is a key player in the marine nitrogen cycle
- Environmental ScienceNature Microbiology
- 2016
The analysis of global 16S rRNA gene databases showed that UCYN-A occurs in surface waters from the Arctic to the Antarctic Circle and thus probably contributes to N2 fixation in a much larger oceanic area than previously thought.
Impacts of Atmospheric Anthropogenic Nitrogen on the Open Ocean
- Environmental ScienceScience
- 2008
Although ∼10% of the ocean's drawdown of atmospheric anthropogenic carbon dioxide may result from this atmospheric nitrogen fertilization, leading to a decrease in radiative forcing, up to about two-thirds of this amount may be offset by the increase in N2O emissions.
Iron conservation by reduction of metalloenzyme inventories in the marine diazotroph Crocosphaera watsonii

Global and targeted proteomic analyses on a key unicellular marine diazotroph Crocosphaera watsonii are used to reveal large scale diel changes in its proteome, including substantial variations in concentrations of iron metalloproteins involved in nitrogen fixation and photosynthesis, as well as nocturnal flavodoxin production.
