In the Proceedings of the National Academy of Sciences, University of California, Irvine researchers report evidence that marine nutrient cycles—essential for sustaining ocean ecosystems—are ...

Among the myriad creatures that populate our ocean, some stand out as having an outsized impact on the marine environment—shaping and maintaining habitats that themselves sustain countless other forms ...

according to a new study published in the New Zealand Journal of Marine and Freshwater Research.

Productivity fuels life in the ocean, drives its chemical cycles, and lowers atmospheric carbon dioxide. Nutrient uptake and export interact with circulation to yield distinct ocean regimes.

Carbon, a building block of life, is constantly moving through different environmental compartments such as biota, the atmosphere, the ocean, soil and sediment, as part of what is called ‘the global ...

It has puzzled scientists for years whether and how bacteria, that live from dissolved organic matter in marine waters ... impact on the oceanic nitrogen cycle compared to that of cyanobacteria.

Since the mid-1900s, humans have been exerting an ever-increasing impact on the global nitrogen cycle. Human activities ... the addition of nitrogen can lead to nutrient imbalance in trees ...
