“…EPS are produced by algae and bacteria (Meiners et al, 2004;Mancuso Nichols et al, 2005b;Meiners and Michel, 2017) and have been found to be enriched in sea ice compared to seawater (e.g., Krembs et al, 2002aKrembs et al, , 2011Meiners et al, 2003Meiners et al, , 2004Riedel et al, 2006;van der Merwe et al, 2009;Underwood et al, 2010;Ewert and Deming, 2011;Aslam et al, 2012;Janssens et al, 2016). EPS are a good candidate for metallic anion binding (Croot and Johansson, 2000;Verdugo et al, 2004) given their high stickiness and negatively charged surfaces (Decho, 1990;Underwood et al, 2010).…”
