Extended Data Table 6 Results of global data compilation of tidal marsh soil carbon density and RM-ANOVA

From: Wetland carbon storage controlled by millennial-scale variation in relative sea-level rise

  1. Values reported are the number of distinct study locations for which relevant data were available, as well as the mean soil carbon density (in grams of carbon per cubic centimetre) (± one standard error) for the most commonly reported depth intervals: 0–20 cm, 20–50 cm and 50–100 cm. A separate RM-ANOVA was conducted for each data-rich Holocene RSLR zone to test for differences in tidal-marsh soil carbon density among soil depth intervals. P values are based on estimated marginal means with the Bonferroni adjustment, with values significant at P < 0.05 in bold. Superscript letters denote significantly different depth intervals within each SLR zone.
  2. *Soil C density values are low for zones I and IV in part owing to the removal of roots before analysis (see Supplementary Table 1).
