Phytoplankton form the basis of the marine food web and are responsible for approximately half of global carbon dioxide (CO2) fixation (∼ 50 Pg of carbon per year). Thus, these microscopic, photosynthetic organisms are vital in controlling the atmospheric CO2 concentration and Earth's climate. Phytoplankton are dependent on sunlight and their CO2-fixation activity is therefore restricted to the upper, sunlit surface ocean (that is, the euphotic zone). CO2 usually does not limit phytoplankton… Expand
Estimating Nitrogen and Phosphorus Cycles in a Timber Reef Deployment Area
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 asExpand
Review and synthesis: iron input, biogeochemistry, and ecological approaches in seawater
The processes involved in the biogeochemical cycle of Fe in the oceans have been intensely discussed in recent decades because this element is limiting to primary productivity in most oceanicExpand
Dynamic interaction between basin redox and the biogeochemical nitrogen cycle in an unconventional Proterozoic petroleum system
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.

Temporal variability of the physical and chemical environment, chlorophyll and diatom biomass in the euphotic zone of the Beagle Channel (Argentina): Evidence of nutrient limitation
Abstract Coastal, semi-enclosed aquatic ecosystems of sub-polar regions surrounded by continental glaciers are among the most sensitive environments to climate change. The Beagle ChannelExpand
Effects of depth-cycling on nutrient uptake and biomass production in the giant kelp Macrocystis pyrifera
Abstract Seasonal or chronic nutrient limitations in the photic zone limit large-scale cultivation of seaweed (macroalgae) in much of the world's oceans, hindering the development of macroalgae as aExpand
Deposition of Aerosols onto Upper Ocean and Their Impacts on Marine Biota
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 mineralExpand
Colonies of marine cyanobacteria Trichodesmium interact with associated bacteria to acquire iron from dust
Evidence is provided for mutualistic interactions between the nitrogen-fixing marine cyanobacteria Trichodesmium and associated bacteria in using iron from dust, where bacteria promote dust dissolution by producing Fe-complexing molecules (siderophores) and Trichodemium provides dust and optimal physical settings for dissolution and uptake.

Monitoring fitness and productivity in cyanobacteria batch cultures
Abstract Cyanobacteria are key photosynthetic organisms in many aquatic ecosystems and hold great potential for sustainable green biotechnology. Growth of cyanobacteria in batch cultures is expectedExpand

On the planet earth silicon is next only to oxygen in abundance. It is ubiquitous and is present in soil, water and air and biological systems from algae to human population. It is removed by cropsExpand
Evidence of nitrification associated with globally distributed pelagic jellyfish
Bioavailable nitrogen is a scarce resource in most of the surface ocean and often limits primary productivity. Although Pelagic jellyfish excrete substantial amounts of ammonia (the preferred form ofExpand


Processes and patterns of oceanic nutrient limitation
Microbial activity is a fundamental component of oceanic nutrient cycles. Photosynthetic microbes, collectively termed phytoplankton, are responsible for the vast majority of primary production inExpand
Phytoplankton in the ocean use non-phosphorus lipids in response to phosphorus scarcity
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
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.

Global patterns of marine nitrogen fixation and denitrification
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.Expand
Doubling of marine dinitrogen-fixation rates based on direct measurements
If the findings can be extrapolated to other ocean basins, this suggests that the global marine N2-fixation rate derived from direct measurements may increase from 103 ± 8 Tg N yr−1 to 177‬±‬8‬‬2, and that the contribution of N2 fixers other than Trichodesmium is much more significant than was previously thought.

Anaerobic ammonium oxidation by anammox bacteria in the Black Sea
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. Expand
Iron fertilization enhanced net community production but not downward particle flux during the Southern Ocean iron fertilization experiment LOHAFEX
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
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—areExpand
