Journal ArticleDOI
Pathways of organic carbon oxidation in three continental margin sediments
Donald E. Canfield,Bo Barker Jørgensen,Henrik Fossing,Ronnie N. Glud,Jens K. Gundersen,Niels B. Ramsing,Bo Thamdrup,Jens Würgler Hansen,Lars Peter Nielsen,Per O. J. Hall +9 more
TL;DR: It is suspected that the importance of O2 respiration in many coastal sediments has been overestimated, whereas metal oxide reduction (both Fe and Mn reduction) has probably been well underestimated.
Journal ArticleDOI
Rapid, small-volume, flow injection analysis for SCO2, and NH4+ in marine and freshwaters
Per O. J. Hall,Robert C. Aller +1 more
TL;DR: A gas-permeable membrane is used to remove CO2 or NH3 from acidic (∑CO2) or basic (NH4+) reagent streams into a receiving stream and conductivity detector as discussed by the authors.
Journal ArticleDOI
The effect of oxygen on release and uptake of cobalt, manganese, iron and phosphate at the sediment-water interface
Bjørn Sundby,Leif G. Anderson,Per O. J. Hall,Åke Iverfeldt,Mlchiel M.Rutgers van der Loeff,Stig Westerlund +5 more
TL;DR: In this article, in situ measurements with a benthic flux chamber, in which dissolved oxygen and pH were maintained near ambient values (regulated flux-chamber), showed that the sediment did not release any of these ions but instead removed Co, Mn, Co, and Fe from the overlying water.
Journal ArticleDOI
Effect of oxygen on degradation rate of refractory and labile organic matter in continental margin sediments
TL;DR: In this paper, the effect of oxygen on the degradation rate of sedimentary organic matter is investigated, and it is shown that the extent of long-term decomposition of organic material is smaller under oxygenated or anoxic conditions alone, than when the material is exposed to the repeated activities of both oxic and anoxic microorganisms.
Journal ArticleDOI

TL;DR: In this article, the authors provide an overview of new knowledge on oxygen depletion (hypoxia) and related phenomena in aquatic systems resulting from the EU-FP7 project HYPOX (http://www.hypox.net).
