Across 19 UK saltmarshes 33 wide diameter (60mm) soil cores were collected. The location of each coring site was recorded using Differential Global Positioning System (DGPS). Prior to analysis the samples were stored at 4 degrees Celsius at the University of St Andrews. Upon return to the laboratory the cores were described following the Troels-Smith scheme. The cores were sub-sampled at 1cm intervals resulting in 1952 samples. Soil dry bulk density, organic carbon content, nitrogen content, δ13Corg and δ15N 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.
