Viability and metabolic assays are commonly used as proxies to assess the overall
metabolism of microorganisms. The variety of these assays combined with little information …

This review has been undertaken to understand the effectiveness of ocean acidification on
oceanic micronutrient metal cycles (iron, copper and zinc) and its potential impacts on …

The chemical speciation of iron (Fe) in oceans is influenced by ambient pH, dissolved
oxygen, and the concentrations and strengths of the binding sites of dissolved organic …

Upwelling of subsurface waters injects macronutrients (fixed N, P, and Si) and micronutrient
trace metals (TMs) into surface waters supporting elevated primary production in Eastern …

We present the first report of the concentrations and stable isotope compositions of Te in the
surface layer of ferromanganese crusts collected from the slope of two seamounts in the …

The speciation of dissolved iron (DFe) in the ocean is widely assumed to consist almost
exclusively of Fe (III)-ligand complexes. Yet in most aqueous environments a poorly defined …

Iron, a crucial element in our environment, plays a vital role in numerous natural processes.
Understanding the presence and concentration of iron in the environment is very important …

A versatile flow analyzer that extended the features of reverse flow injection analysis (rFIA)
was developed in this study and named reverse flow dual-injection analysis (rFDIA) …

The redox speciation of iron was determined during the iron fertilization LOHAFEX and for
the first time, the chemiluminescence assay of filtered and unfiltered samples was …

Cyanobacteria have high iron requirements due to iron-rich photosynthetic machineries.
Despite the high concentrations of iron in the Earth's crust, iron is limiting in many marine …
