MOESM1 of Onboard experiment investigating metal leaching of fresh hydrothermal sulfide cores into seawater

Additional file 1: Table S1. pH and concentrations of Fe, Cu, Zn and Pb in seawater from powdered core samples at different temperature and redox conditions. Figure S1. Photographs of hydrothermal mineral cores for onboard leaching experiment: (a) C9026A 7X-CC (CKL-1), (b) C9027B 1X-CC (CKL-2), (c) C9028A 7S-CC (CKL-3), and (d) C9028A 1H-7 (CKL-4). Figure S2. Images of onboard leaching experiment: (a) an operation in the anaerobic chamber and (b) sample reactions in the water baths. Figure S3. Changes in Eh (V, SHE) for (a) CKL-1, (b) CKL-2, (c) CKL-3, and (d) CKL-4 solutions under different redox and temperature conditions. Plots show mean values of duplicates, and error bars indicate range of duplicate (difference between the max and min values).
