SNN116596 - Data from a Geochemical and Magnetic Susceptibility Survey at Blank Area Testing, Brackley to Southam, Northamptonshire, 2020-2022 (HS2 Phase One)

This collection comprises a digital archive of spreadsheets from a geochemical and magnetic susceptibility survey, by Archaeological Research Services on Blank Area Testing sites from Brackley to Southam in Northamptonshire. Project Summary Archaeological Research Services Ltd undertook a programme of geochemical (GC) and magnetic susceptibility (MS) prospection to inform an extensive test pit survey across 31 fields to test the presence of significant archaeological deposits in areas identified as ‘Blank Areas’. The fields were organised into eight field packages and extended across the HS2 rail formation line from Brackley to Southam. The total area investigated covered 184ha and involved the characterisation of 6206 sample points by GC and MS and the subsequent excavation of 1544 manually excavated test pits (656 x 0.25sqm, 888 x 1sqm). Reuse Value Statement This archive forms part of the archaeological investigative work undertaken ahead of the construction of High Speed 2. All of the files contained within this archive are suitable for reuse as they are in standard, easy accessible formats, in line with the FAIR Principles. The archive may be looked at in conjunction with other HS2 archives to further add depth and context to the works. Further mitigation works have taken place on site and this archive should be viewed in conjunction with that.
