The data contained in this repository describes biogeochemical and physicochemical characterisation data in samples collected from adjacent to the United Kingdom’s Sellafield Nuclear Site. It includes particle size distribution and textural classification, pH measurements, water and organic carbon content (loss on ignition), BET surface area, bioavailability of iron, cation exchange, permeability measurements, X-ray analysis for phase (X-ray diffraction, XRD) and element (X-ray fluorescence, XRF) identification, ion chromatography, thin sectioning and 16S Ribosomal (rRNA) gene analysis.

We present characterisation data for sediments consistent with the quaternary lithography located beneath the Sellafield nuclear site, UK. Geologically contiguous samples were collected, stored under ambient conditions and analysed. Analysis data described here include particle size distribution and textural classification, pH measurements for soil acidity, water and organic carbon content (loss on ignition), BET surface area, bioavailability of iron, cation exchange capacity for ion exchange capability, permeability measurements, gamma spectroscopy for radiological characterisation, X-ray analysis for phase (X-ray diffraction, XRD) and element (X-ray fluorescence, XRF) identification, ion chromatography for leachable ion concentrations, thin sectioning and optical and scanning electron microscopy (SEM) coupled with energy-dispersive X-ray spectroscopy (EDX) for particle visualisation, and 16S ribosomal RNA (rRNA) for biogeochemical characterisation. We expect these data to be useful to site remediators, scientists and those examining biogeochemical and/or physical sediment processes at nuclear sites as well as site remediation efforts in the wider community.
