Dr. Tanja Stratmann has been awarded the prestigious Starting Grant by the European Research Council (ERC). Starting in 2026, ...

In the nitrogen cycle, phytoplankton and other marine plants turn nitrate (NO 3) into organic nitrogen during photosynthesis. The organic nitrogen sinks into the deep ocean, where microbes "eat" the ...

Nitrogen is one of the primary nutrients critical for the survival of all living organisms. Although nitrogen is very abundant in the atmosphere, it is largely inaccessible in this form to most ...

Limnology and Oceanography, Vol. 66, No. 12 (December 2021), pp. 4159-4170 (12 pages) Urea sinks are mainly associated with assimilation by phytoplankton. However, recent studies have shown that there ...

Limnology and Oceanography, Vol. 64, No. 3 (May 2019), pp. 1270-1283 (14 pages) Nitrogen (N), as a critical element for microbial metabolisms, recycles rapidly in the euphotic ocean. Oxidation by ...

In Florida, large mats of sargassum are increasingly washing ashore, creating another obstacle for loggerhead, leatherback ...

In the deep waters that underlie the productive zones of the ocean, there is a constant rain of organic material called 'marine snow.' Marine snow behaves similarly to real snow: large flakes are rare ...

It is common knowledge that there would be no oxygen on Earth were it not for sunlight; the key component in photosynthesis. Now researchers have made the surprising discovery that oxygen is also ...

Andrew Babbin tries to pack light for work trips. Along with the travel essentials, though, he also brings a roll each of electrical tape, duct tape, lab tape, a pack of cable ties, and some bungee ...

Eukaryotic phytoplankton drive a decrease in primary production under ocean acidification. Credit: Dalin Shi Princeton University and Xiamen University researchers report that in tropical and ...

Imagine if Earth's history had a mystery novel, and one of its biggest unsolved puzzles was: Where did all the nitrogen go? Scientists have long known that our planet's rocky outer layers—the ...
