a–d, GPS production data for the reaction of glucose and glycine under continental margin sediment temperature, plotted as time (years) versus GPS (nmol l−1) in the presence of dissolved Fe (a), dissolved Mn (b), Fe mineral (ferrihydrite) (c) and Mn mineral (birnessite) (d). All centre points represent the average, and error bars represent one standard error of the mean (n = 3). e, Linear regressions of data used for calculation of GPS production rate (R) with coefficient of determination (R2). Green and purple colour codes depict Fe and Mn data, respectively.
