Mineral dust deposition is suggested to be a significant atmospheric supply pathway of bioavailable iron
(Fe) to Fe-depleted surface oceans.
The role of polysaccharides and diatom exudates in the redox cycling of Fe and the photoproduction of hydrogen peroxide in coastal seawaters
polysaccharides and diatom exudates the redox cycling of Fe the photoproduction of hydrogen peroxide coastal seawaters
2010/1/21
The effect of artificial acidic polysaccharides (PS) and exudates of Phaeodactylum tricornutum on the half-life of Fe(II) in seawater was investigated in laboratory experiments. Strong photochemical h...
