Presented here are compiled data of sediment accretion across UK saltmarshes. All data have been collected using globally standardised methods of monitoring sediment accretion using the rod Sediment Elevation Table – Marker Horizon (rSET-MH) methods. In 2023 UKCEH deployed sediment elevation tables in the Dornoch Firth, the Solway Firth, The Ribble, The Wash, North Norfolk and Chichester Harbour, the data for which are included here. Sites were monitored again using the same technique in the Spring of 2024. Marker horizons cores were also taken at sites in the Wash, North Norfolk, the Ribble and Chichester Harbour.
