Reactive Barriers Could Keep Nitrate out of the Atlantic
Microbes in mulch scrub nitrate from groundwater before it flows to the sea.
The Open Ocean, Aerosols, and Every Other Breath You Take
Phytoplankton and other marine plants produce half of Earth’s atmospheric oxygen and have big effects on food webs and climate. To do so, they rely on nutrients from the sky that are hard to quantify.
What Happens to Nutrients After They Leave Agricultural Fields?
To better quantify the fate of nutrients after they are released from agricultural fields, scientists examine storage and nitrate export regimes in agricultural hydrology systems.
OneHealth, Climate Change, and Infectious Microbes
AGU and ASM welcome submissions to a joint special collection focusing on the impacts of climate change and microbes on human well-being.
New Constraints on Sulfur Cycling in the Prebiotic Earth
Experiments constraining rates of aqueous reactions and photolysis coupled with a global model constrain the abundance and chemical speciation of sulfur in early Earth’s atmosphere and oceans.
How Nutrients Get Back Up to the Surface Ocean
A new dual isotope tracer technique is used to assess the role of a number of poorly understood nutrient supply mechanisms fueling biological productivity in the ocean.
Flash Floods May Support One of the World’s Rarest Fish
Only a few hundred Devils Hole pupfish live in an isolated pool in the desert, where occasional floodwaters roil their habitat.
Nutrients at Depth Can Be Uplifted by the Kuroshio Large Meander
Aperiodic, southward deflection of the Kuroshio, a.k.a. the Kuroshio large meander, uplifts the nutrients in deep layers to induce offshore phytoplankton bloom.
Ocean Deserts Could Help Capture CO2 and Mitigate Global Warming
Various nutrient sources in the upper waters of oceanic subtropical gyres, which are the Earth’s largest oligotrophic ecosystems, play a crucial role in governing the sequestration of atmospheric CO2.
