Spatial mapping of the sediment type and the carbon (C) stored in the top 10 cm of the sediments found across the seabed of the United Kingdom’s Exclusive Economic Zone (EEZ) and within the territorial waters of the Isle of Man and the Channel Islands. The dataset contains two resources:
UK EEZ Sediment Type: Spatial mapping of seafloor sediment type classified using the modified Folk scheme.
UK EEZ Surficial Sedimentary Carbon: Spatial mapping of the organic carbon (OC) and inorganic (IC) in the top 10 cm of sediments.
The work is part of the Scottish Blue Carbon Forum research programme funded by the Scottish Government.

The mapping is based of 203,710 surficial (top 10cm) seabed descriptions, physical property and geochemical data points collected from primary and secondary sources. The seabed descriptions were harmonized into 16 classes using a modified Folk classification scheme. Indicator Kriging was used to map the categorical variables (e.g. sediment type) across the UK EEZ. Simple Kriging, with spherical semi-variogram with Gaussian geostatistical simulations was combined with the physical property and geochemical data to map the spatial distribution of OC and IC across the seabed of the UKEEZ. All calculations and modelling were carried out within the ESRI ArcGIS software package using the spatial interpolation, raster calculator and the zonal statistics tools
