One-quarter of photosynthesis-derived carbon on Earth rapidly cycles through a set of short-
lived seawater metabolites that are generated from the activities of marine phytoplankton …

Microbes of the surface ocean release, consume, and exchange labile metabolites at time
scales of minutes to days. The details of this important step in the global carbon cycle remain …

Diatoms are a major component of phytoplankton community. They tend to dominate under
natural high-nutrient concentrations, as well as during artificial Fe fertilisation experiments …

In both marine and freshwaters, the concentration of dissolved organic nitrogen (DON)
frequently exceeds that of dissolved inorganic nitrogen (DIN), including ammonium, nitrate …

Sea-surface warming, sea-ice melting and related freshening, changes in circulation and
mixing regimes, and ocean acidification induced by the present climate changes are …

Active heterotrophic bacterial communities exist in all marine environments, and although
their growth rates or respiratory rates may be limited by the interaction of low substrate …

Phytoplankton population dynamics are the result of imbalances between reproduction and
losses. Losses include grazing, sinking, and natural mortality. As the importance of microbes …

Since the first edition of Nitrogen in the Environment published in 1983, it has been
recognized as the standard in the field. In the time since the book first appeared, there has …

Unicellular, planktonic, prokaryotic and eukaryotic photoautotrophs (phytoplankton) have an
ancient evolutionary history on Earth during which time they have played key roles in the …

The element carbon plays a central role in climate and life on Earth. It is capable of moving
among the geosphere, cryosphere, atmosphere, biosphere and hydrosphere. This flow of …
