Fig. 6: Relationships between dissolved organic carbon (DOC) fluxes and weathering congruency at the four depths.
From: Mineral weathering is linked to microbial priming in the critical zone
Corrected DOC fluxes (fDOC-corr) and normalized Si concentration/Na concentration ([Si]/[Na]norm) show positive covariation in the topsoil (a, b) but negative covariation below the topsoil (c–h). Dashed lines in the time-series plots represent three- or four-point averages. In most cases, three porewater samples were collected from the three pits on each sampling date. Note that the time-series scale is not uniform.
