Across 22 UK saltmarshes 462 narrow diameter (30mm) soil cores were collected, the cores were described in the field following the Troels-Smith scheme. The cores were sub-sampled in the field at 10cm intervals resulting in 3434 samples. The location of each coring site was recorded using DGPS. Prior to analysis the samples were stored at 4 degrees Celsius at the University of St Andrews. Soil dry bulk density and organic carbon content was measured using standard analytical procedures (detailed in the supporting documentation). All laboratory equipment were calibrated in accordance with the laboratory practises at the University of St Andrews. Results were recorded on to lab sheets and transferred into an Excel file. Results were exported as comma separated value (.csv) files for ingestion into the EIDC.
