Extended Data Table 3 Sunlight exposure times, photon doses, and amounts of light absorbed by CDOM during each sunlight exposure experiments to quantify apparent quantum yields for DOC photomineralization

From: Canal networks regulate aquatic losses of carbon from degraded tropical peatlands

  1. Concentrations of DIC produced and the photomineralization yield at 350 nm (φCO2,350) are reported as the average ± 1 s.e.m. of experimental replicates (n = 4). Exposure times of DOC in the drainage canals corresponding to each φCO2,350 are reported as the average (minimum – maximum), where the range of potential exposure times are from low and high photon fluxes (Extended Data Fig. 3; Supplementary Section 1.2). The daily photon doses reaching each canal on the primary day of the experiment (mol photon m−2 d−1; Extended Data Fig. 3) were used to calculate daily photomineralization rates under optimal conditions (Fig. 2a) and those scaled to water column rates in the canal (Fig. 2b; see Methods). Data for each canal water sample are reported in the same order as in Extended Data Table 1.
