Light energy is a driver for many biogeochemical element cycles in aquatic systems. The
sunlight-induced photochemical reduction of ferric iron (Fe (III) photoreduction) to ferrous …

Heavy metals are occurring in the aquatic environment as the result of natural or
anthropogenic inputs, and depending on concentration, availability and resilience time, they …

A major surface circulation feature of the Arctic Ocean is the Transpolar Drift (TPD), a current
that transports river‐influenced shelf water from the Laptev and East Siberian Seas toward …

Siderophores are strong iron‐binding molecules produced and utilized by microbes to
acquire the limiting nutrient iron (Fe) from their surroundings. Despite their importance as a …

It is now widely accepted that siderophores play a role in marine iron biogeochemical
cycling. However, the mechanisms by which siderophores affect the availability of iron from …

The distribution of dissolved iron (Fe), total organic Fe-binding ligands, and siderophores
were measured between the surface and 400 m at Station ALOHA, a long term ecological …

Copper distribution and speciation were determined at stations P4 and P26 along Line P as
part of a GEOTRACES Process Study in the Northeast Pacific, at depths between 10 and …

It is well recognized that the atmospheric deposition of iron (Fe) affects ocean productivity,
atmospheric CO 2 uptake, ecosystem diversity, and overall climate. Despite significant …

The iron (Fe) biogeochemical cycle is critical for abiotic and biological many environmental
processes, both abiotic and biological, that overlap spatially and may compete with each …

Iron-binding ligands are paramount to understanding iron biogeochemistry and its potential
to set the productivity and the magnitude of the biological pump in> 30% of the ocean …
