Shedding New Light on the Nitrogen Cycle in the Dark Ocean
Researchers find that the key players in nitrification may already be known.
Artificial Intelligence Can Spot Plankton from Space
Training an algorithm with satellite images of ocean color reveals the blooms and busts of phytoplankton communities.
The Kuroshio Current: Artery of Life
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.
Far-Flung Dust Storms Deliver Nutrient Boosts to North Pacific
Barren marine deserts bloom seasonally with iron infusions from Asian dust storms.
Unraveling Hemispheric Ocean Nitrate Supply Pathways
Subsurface measurements of nitrogen and oxygen isotope ratios in nitrate reveal a predominantly southern hemisphere supply of nitrate to the equatorial Pacific.
Bringing Biogeochemistry into the Argo Age
Plans are underway to integrate and augment a collection of regional programs to form a global biogeochemical monitoring network.
A New Mechanism for Nitrogen Cycling in the Southern Ocean
A nitrite-oxidizing enzyme may work in reverse for some microbes in the Antarctic autumn.
