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 …

Climate projections suggest–with substantial certainty–that global warming> 1.5° C will
occur by mid-century (2050). Population is also projected to increase, amplifying the …

Eutrophication is a complex process and often associated with not only a change in overall
algal biomass but also with a change in biodiversity. Common metrics of eutrophication (eg …

Protist plankton are major members of open‐water marine food webs. Traditionally divided
between phototrophic phytoplankton and phagotrophic zooplankton, recent research shows …

Many protist plankton are mixotrophs, combining phototrophy and phagotrophy. Their role in
freshwater and marine ecology has emerged as a major develo** feature of plankton …

Freshwater discharge from glaciers is increasing across the Arctic in response to
anthropogenic climate change, which raises questions about the potential downstream …

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 …

Photosynthesis evolved in the ocean more than 2 billion years ago and is now performed by
a wide range of evolutionarily distinct organisms, including both prokaryotes and …

Rising concentrations of atmospheric CO 2 results in higher equilibrium concentrations of
dissolved CO 2 in natural waters, with corresponding increases in hydrogen ion and …

Microbial interactions are crucial for Earth ecosystem function, but our knowledge about
them is limited and has so far mainly existed as scattered records. Here, we have surveyed …
