Oxidation of Fe(II) in the North Atlantic waters in
the presence of organic compounds
Carolina Santana
González presented her PhD Thesis the last Friday
(23rd September) entitled “Oxidation
of Fe(II) in the North Atlantic waters in the presence of organic compounds”.
The PhD Thesis
was carried out in the Universidad de Las Palmas de Gran Canaria, at the
Instituto de Oceanografía y Cambio Global (IOCAG), in the QUIMA group, inside
the IOCAG Doctoral Program in Oceanography and Global Change. This PhD is
linked to the EACFe (CTM2014-52342-P) and ATOPFe (CTM2017-83476-P) research projects by the Ministerio de
Economía y Competitividad of the Spanish Government. In addition, the PhD was
made possible by the FPI grant (BES-2015-071245) of the Ministerio de Economía
y Competitividad of the Spanish Government associated to the EACFe project. The
PhD was supervised by Dra. J. Magdalena Santana Casiano and Dr. Melchor
González Dávila.
In summary, the
Fe(II) oxidation kinetics has been studied in seawater of the North Atlantic
Ocean. The spatial distribution of the samples affected the oxidation rate of
Fe(II) due to the chemical characteristics of each water mass sampled. Faster
Fe(II) oxidation rates were observed within the chlorophyll maximum, in surface
and coastal samples than in deep waters related with the remineralization state
of the organic matter.
