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 ...

Ocean microbes can use urea when ammonium is scarce. This helps them survive in poor waters and reshapes our view of the nitrogen cycle.

Ammonia-oxidizing archaea (AOA) are some of the most abundant microorganisms in the ocean and play a key role in nitrogen ...

As much as a third of the nitrogen entering the world’s oceans from the atmosphere is man-made, according to new findings by an international team of scientists. This has significant implications for ...

Researchers have uncovered surprising evidence that the deep ocean’s carbon-fixing engine works very differently than long ...

It has puzzled scientists for years whether and how bacteria, that live from dissolved organic matter in marine waters, can carry out N 2 fixation. It was assumed that the high levels of oxygen ...

In an effort to better understand how the ocean stores carbon, researchers at UC Santa Barbara and their collaborators have uncovered results that ...

Limnology and Oceanography, Vol. 62, No. 5 (September 2017), pp. 1895-1909 (15 pages) Recent observations of N₂ fixation rates (NFR) and the presence of nitrogenase (nifH) genes from heterotrophic ...

Limnology and Oceanography, Vol. 59, No. 3 (2014), pp. 972-985 (14 pages) Taxon-specific nitrogen (N) isotope data from the summertime Sargasso Sea have previously suggested reliance of prokaryotic ...

UCSB research offers a new perspective on how carbon is stored in the deep ocean and what it could mean for maintaining Earth’s long-term climate balance Scientists are taking an important step toward ...
