Metal dissolution from atmospheric aerosol deposition to the oceans is important in
enhancing and inhibiting phytoplankton growth rates and modifying plankton community …

Discrepancies between estimates of oceanic N 2 fixation and nitrogen (N) losses through
denitrification have focused research on identifying N 2-fixing cyanobacteria and quantifying …

Nutrient availability limits phytoplankton growth throughout much of the global ocean. Here
we synthesize available experimental data to identify three dominant nutrient limitation …

Nutrient supply regulates the activity of phytoplankton, but the global biogeography of
nutrient limitation and co-limitation is poorly understood. Prochlorococcus adapt to local …

Marine N 2 fixing microorganisms, termed diazotrophs, are a key functional group in marine
pelagic ecosystems. The biological fixation of dinitrogen (N 2) to bioavailable nitrogen …

The marine nitrogen (N) cycle controls the productivity of the oceans. This cycle is driven by
complex biogeochemical transformations, including nitrogen fixation, denitrification, and …

Coastal upwelling regimes associated with eastern boundary currents are the most
biologically productive ecosystems in the ocean. As a result, they play a disproportionately …

Climate change will alter concurrently many environmental factors that exert control over
oceanic phytoplankton. Recent laboratory culture work, shipboard experiments, and field …

Iron is essential for all life, but it is particularly important to photoautotrophs because of the
many iron-dependent electron transport components in photosynthetic membranes. Since …

Prochlorococcus is the key phytoplanktonic organism of tropical gyres, large ocean regions
that are depleted of the essential macronutrients needed for photosynthesis and cell growth …
