Experiment design and bacterial abundance control extracellular H2O2 concentrations during four series of mesocosm experiments
Hopwood, M. J.; Sanchez, Nicolas; Polyviou, Despo; Leiknes, Øystein; Gallego-Urrea, Julian Alberto; Achterberg, Eric P.; Ardelan, Murat Van; Aristegui, Javier; Bach, Lennart T.; Besiktepe, Sengul; Heriot, Yohann; Kalantzi, Ioanna; Terblylk Kurt, Tuba; Santi, Ioulia; Tsagaraki, Tatiana Margo; Turner, David (Peer reviewed; Journal article, 2020)The extracellular concentration of H2O2 in surface aquatic environments is controlled by a balance between photochemical production and the microbial synthesis of catalase and peroxidase enzymes to remove H2O2 from solution. ... -
Fe(II) stability in coastal seawater during experiments in Patagonia, Svalbard, and Gran Canaria
Hopwood, Mark J.; Santana-González, Carolina; Gallego-Urrea, Julian Alberto; Sanchez, Nicolas; Achterberg, Eric P.; Ardelan, Murat Van; Gledhill, Martha; González-Dávila, Melchor; Hoffmann, Linn; Leiknes, Øystein; Santana-Casiano, Juana Magdalena; Tsagaraki, Tatiana Margo; Turner, David (Peer reviewed; Journal article, 2020)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 fraction of DFe also exists as Fe(II), the ...
