Still, it has been an open question why the bacteria carrying out this N 2 fixation can be found worldwide in the ocean ... impact on the oceanic nitrogen cycle compared to that of cyanobacteria.

They have been extensively studied in natural environments such as soils, estuaries, lakes, and open-ocean environments ... of Human Alterations to the Nitrogen Cycle Many human activities ...

Sebastian Haas is a CERE.OCEAN PhD cadidate who leads the research of nitrogen cycle from the Bedford Basin Time Series. Nitrogen is a major nutrient supporting the growth of phytoplankton, which are ...

Wang said a likely next step in this research would be to determine how the flow of nitrogen into the ocean from human activity can impact the ocean’s nutrient cycle. “The key questions lie in our ...

A study of ancient stromatolites reveals that ammonium reservoirs in early Earth's oceans, likely influenced by volcanic activity, may have supported microbial life before the Great Oxidation Event.

Nitrogen is vital for all life on Earth but must first be converted into useable, bioavailable, forms as it passes through the atmosphere, soil, plants and animals in the nitrogen cycle.

Nitrogen is vital for all life on Earth but must first be converted into useable, bioavailable, forms as it passes through the atmosphere, soil, plants and animals in the nitrogen cycle.

Nutrient availability, particularly nitrogen, influenced this response. Results indicate that ocean acidification could reduce primary production in oligotrophic tropical and subtropical oceans by ...

Carly Buchwald’s group uses the abundance stable isotopes of N and O in nitrite and nitrate to interpret nitrogen biogeochemistry in the environment. They measure the isotope systematics of relevant ...
