Paper alert 🚨 Interaction of metal oxyions with carbonate green rust in seawater is out now! This is one of the few papers that investigated metal uptake with GRCO3 in seawater and conducted 1 year aging experiments!

Abstract. Zinc (Zn) is an essential micronutrient for most eukaryotic phytoplankton. Zn uptake by phytoplankton within the euphotic zone results in nutrient-like dissolved Zn (dZn) profiles with a lar...
