The evolution of stream dissolved organic matter composition following glacier retreat in coastal watersheds of southeast Alaska
Climate change is melting glaciers and altering watershed biogeochemistry across the globe, particularly in regions dominated by mountain glaciers,...

Dissolved organic matter in large lakes: a key but understudied component of the carbon cycle
The world’s largest five freshwater lakes include tropical meromictic, temperate weakly stratified, and temperate holomictic lakes ranging in age...

Origin and fate of dissolved organic matter in four shallow Baltic Sea estuaries
Coastal waters have strong gradients in dissolved organic matter (DOM) quantity and characteristics, originating from terrestrial inputs and...

Urea is a potentially important nitrogen source for phytoplankton during red tide formation in Isahaya Bay, Japan
Isahaya Bay in Japan has suffered from severe red tides. A previous study reported that red tides continued under dissolved inorganic nitrogen (DIN)...

How humans alter dissolved organic matter composition in freshwater: relevance for the Earth’s biogeochemistry
Dissolved organic matter (DOM) is recognized for its importance in freshwater ecosystems, but historical reliance on DOM quantity rather than...

Role of Resuspended Sediments as Sources of Dissolved Inorganic Phosphorus Along Different Dimensions in the Subei Shoal, South Yellow Sea, China
Several studies have documented that during ‘green tide’ events, comprising green macroalgae blooms in aquatic ecosystems, dissolved inorganic...

Substantial contribution of tree canopy nitrifiers to nitrogen fluxes in European forests
Human activities have greatly increased the reactive nitrogen in the biosphere, thus profoundly altering global nitrogen cycling. The large increase...

In-situ N2:Ar ratios describe the balance between nitrogen fixation and denitrification in shallow eutrophic experimental lakes
Quantifying net N 2 flux, the balance between nitrogen (N) fixation and denitrification, may help inform the decades-long debate about the...

Nitrogen fixation facilitates stream microbial mat biomass across the McMurdo Dry Valleys, Antarctica
Nitrogen (N) fixation is a fundamental mechanism by which N enters streams. Yet, because of modern N saturation, it is difficult to study the...

Influence of nitrogen wet deposition on nitrogen output in a typical watershed in the Three Gorges Reservoir Area
In order to explore the influence of wet nitrogen (N) deposition on N output in watersheds, this study selected a typical small watershed...

A primary magmatic source of nitrogen to Earth’s crust
The igneous portion of Earth’s continental crust represents a long-term sink of terrestrial nitrogen, but the origin of the nitrogen in this...
