Journal ArticleDOI
The evolution and future of earth's nitrogen cycle
TL;DR: Humans must modify their behavior or risk causing irreversible changes to life on Earth, as the damage done by humans to the nitrogen economy of the planet will persist for decades, possibly centuries, if active intervention and careful management strategies are not initiated.
Journal ArticleDOI
The Global Carbon Cycle: A Test of Our Knowledge of Earth as a System
Paul G. Falkowski,Robert J. Scholes,Edward A. Boyle,Josep G. Canadell,Donald E. Canfield,James J. Elser,Nicolas Gruber,K. Hibbard,Peter Högberg,Sune Linder,Fred T. Mackenzie,Berrien Moore,Thomas F. Pedersen,Yair Rosenthal,Sybil P. Seitzinger,Victor Smetacek,Will Steffen +16 more
TL;DR: It is concluded that although natural processes can potentially slow the rate of increase in atmospheric CO2, there is no natural "savior" waiting to assimilate all the anthropogenically produced CO2 in the coming century.
Journal ArticleDOI
The use of chromium reduction in the analysis of reduced inorganic sulfur in sediments and shales
Donald E. Canfield,Robert Raiswell,Joseph T. Westrich,Christopher M. Reaves,Robert A. Berner +4 more
TL;DR: In this article, a chromium reduction method was used for the determination of reduced inorganic sulfur compounds (pyrite + elemental sulfur + acid volatile monosulfides) in modern sediments and shales.
Journal ArticleDOI
A new model for Proterozoic ocean chemistry
TL;DR: In this article, the authors argue that anoxic bottom waters probably persisted until well after the deposition of banded iron formations ceased, and they also propose that sulphide, rather than oxygen, was responsible for removing iron from deep ocean water.
Journal ArticleDOI
Reactive iron in marine sediments
TL;DR: It appears that distinct microenvironments may exist in marine sediments, where, in one microenvironment, sulfide reacts with Fe oxides locally precipitating Fe sulfide minerals, and in another, Fe reduced and solubilized by microorganisms migrates freely into solution.
