The micronutrient iron is now recognized to be important in regulating the magnitude and
dynamics of ocean primary productivity, making it an integral component of the ocean's …

Covering: 1950 up to the end of 2009 Siderophores are compounds produced by bacteria,
fungi and graminaceous plants for scavenging iron from the environment. They are low …

The biogeochemical cycles of iron and organic carbon are strongly interlinked. In oceanic
waters, organic ligands have been shown to control the concentration of dissolved iron. In …

Advances in iron biogeochemistry have transformed our understanding of the oceanic iron
cycle over the past three decades: multiple sources of iron to the ocean were discovered …

The iron sulfides constitute a diverse group of solids and dissolved complexes many of
which play key roles in marine systems. The group is particularly complex in the lower …

Planktonic uptake of some essential metals results in extraordinarily low concentrations in
surface seawater. To sequester or take up these micronutrients, various microorganisms …

Few of us may ever live on the sea or under it, but all of us are making increasing use of it
either as a source of food and other materials, or as a dump. As our demands upon the …

Marine microalgae support world fisheries production and influence climate through various
mechanisms. They are also responsible for harmful blooms that adversely impact coastal …

The role of iron in enhancing phytoplankton productivity in high nutrient, low chlorophyll
oceanic regions was demonstrated first through iron-addition bioassay experiments and …

In addition to control by major nutrient elements (nitrogen, phosphorus, and silicon) the
productivity and species composition of marine phytoplankton communities are also …
