Researchers find that the key players in nitrification may already be known.
Training an algorithm with satellite images of ocean color reveals the blooms and busts of phytoplankton communities.
The waters of the Kuroshio Current in the northwestern Pacific Ocean transport heat, salt, and organic and inorganic matter from south to north, shaping the ocean ecosystem.
Barren marine deserts bloom seasonally with iron infusions from Asian dust storms.
Subsurface measurements of nitrogen and oxygen isotope ratios in nitrate reveal a predominantly southern hemisphere supply of nitrate to the equatorial Pacific.
Plans are underway to integrate and augment a collection of regional programs to form a global biogeochemical monitoring network.
A nitrite-oxidizing enzyme may work in reverse for some microbes in the Antarctic autumn.
Next-generation autonomous platforms allow scientists to understand physical mechanisms that control nitrate availability in the Mediterranean surface water.
