Extended Data Table 1 Sample details

From: Mineral protection regulates long-term global preservation of natural organic carbon

  1. Sample locations, collection details, screening procedure results, %OC, Fm and references32,33,34,35,36,38,39,40,41,42,43,44,45,46 are shown. Environ., environment (sed., marine sediment); Anthro., anthropogenically contaminated; Lat., latitude; Long., longitude; Std. dev., standard deviation; Bulk Fm Calc., Bulk Fm calculation method (meas., measured; wt. av., weighted average of RPO fractions); Pyr./Ox., pyrolysis or oxidation mode.
  2. *See Methods for screening procedure details.
  3. †Samples that originally contain CO3 but have been acidified before RPO analysis are marked ‘n’.
  4. ‡Empty cells represent missing or nonexistent data.
  5. §If no uncertainty is reported, then standard deviation is taken to be the maximum of 0.01 or 1% of measured %OC.
  6. ||If no uncertainty is reported, then standard deviation is taken to be 0.005 Fm units.
  7. Soil orders according to USDA soil taxonomy: P, peat; E, Entisol; UB, Udic Boroll; A, Andisol.
