The ecological and oceanographic processes that drive the response of pelagic ocean
microbiomes to environmental changes remain poorly understood, particularly in coastal …

Diatoms are prominent eukaryotic phytoplankton despite being limited by the micronutrient
iron in vast expanses of the ocean. As iron inputs are often sporadic, diatoms have evolved …

Changes in iron (Fe) bioavailability influence diatom physiology and community composition,
and thus have a profound impact on primary productivity and ecosystem dynamics. Iron …

Diatom primary productivity is tightly coupled with carbon export through the ballasted
nature of the silica-based cell wall, linking the oceanic silicon and carbon cycles. However, …

Iron availability limits primary productivity in large areas of the world's oceans. Ascertaining
the iron status of phytoplankton is essential for understanding the factors regulating their …

Frequent blooms of phytoplankton occur in coastal upwelling zones creating hotspots of
biological productivity in the ocean. As cold, nutrient‐rich water is brought up to sunlit layers …

Trace metals and B‐vitamins play critical roles in regulating marine phytoplankton growth
and composition. While some microorganisms are capable of producing certain B‐vitamins, …

Microeukaryotes (protists) serve fundamental roles in the marine environment as contributors
to biogeochemical nutrient cycling and ecosystem function. Their activities can be inferred …

The formation of marine snow (MS) by the toxic diatom Pseudo-nitschia australis was simulated
using a roller table experiment. Concentrations of particulate and dissolved domoic acid (…

Coastal upwelling regions are among the most productive marine ecosystems but may be
threatened by amplified ocean acidification. Increased acidification is hypothesized to reduce …
