The prokaryotic and eukaryotic microorganisms that drive the pelagic ocean's
biogeochemical cycles are currently facing an unprecedented set of comprehensive …

The oceans take up over 1 million tons of anthropogenic CO2 per hour, increasing dissolved
p CO2 and decreasing seawater pH in a process called ocean acidification (OA). At the …

Uncertainty in the global patterns of marine nitrogen fixation limits our understanding of the
response of the ocean's nitrogen and carbon cycles to environmental change. The …

The global nitrogen (N) cycle at the beginning of the 21st century has been shown to be
strongly influenced by the inputs of reactive nitrogen (N r) from human activities, including …

The availability of the micronutrient iron governs phytoplankton growth across much of the
ocean, but the global iron cycle is changing rapidly due to accelerating acidification …

Marine plankton are faced with novel challenges associated with environmental changes
such as ocean acidification, warming, and eutrophication. However, data on the effects of …

Global warming in ocean ecosystems alters temperature, acidification, oxygen content,
circulation, stratification, and nutrient inputs. Microorganisms play a dominant role in global …

Cyanobacteria are major contributors to global biogeochemical cycles. The genetic diversity
among Cyanobacteria enables them to thrive across many habitats, although only a few …

Model projections indicate that climate change may dramatically restructure phytoplankton
communities, with cascading consequences for marine food webs. It is currently not known …

The temporal dynamics of phytoplankton growth and activity have large impacts on fluxes of
matter and energy, yet obtaining in situ metabolic measurements of sufficient resolution for …
