This document is the drillers log of strata encountered during site investigation work. The log was made in the field during drilling at Prees, Shropshire on 8th to 10th January 2020. The log includes basic information on lithology and drilling equipment used and depths of the individual core runs.

The Bedrock summary lithologies dataset is digital geological map across the bulk of the UK Continental Shelf (UKCS), for areas up to a water depth of 200m, which groups the bedrock lithologies (rock types) into classes based on similar engineering geology characteristics. The map is derived from the 1:250,000 scale digital bedrock map of the UKCS, called DiGRock250k, which is available separately from the BGS. The map was produced in 2014 in collaboration with, and co-funded by, The Crown Estate as part of a wider commissioned project to assess seabed geological constraints on engineering infrastructure across the UKCS. The divisions on the map combine the bedrock formations into 8 classes (with several subdivisions) of similar strength and lithological variability, each with a ‘Category’ title that summarises their main lithological character: Class1 – Igneous; Class 2 - Tertiary Sandstone and Limestone; Class 2.5 - Tertiary Sandstone and Limestone Interbedded; Class 3 - Tertiary Mudstone; Class 4 - Mesozoic Sandstone and Limestone; Class 4.5 - Mesozoic Sandstone and Limestone Interbedded; Class 5 - Mesozoic Mudstone; Class 6 – Chalk; Class 7 – Metamorphic; Class 8 - Palaeozoic Sedimentary. The data are held by the BGS as an ESRI ArcGIS Shapefile.

The dataset indicates the potential for hazard in Great Britain as a result of mineral extraction. It excludes areas of Coal mining as these are covered by the Coal Authority. It is based on a simple A-E rating scale indicating the increasing likelihood of an underground mining hazard. The data was created using expert knowledge, detailed literature searches, local knowledge and a series of rule based geological constraints applied to the DigMapGB50k (Digital Geological Map of Great Britain) data.

Drop Camera collecting video and still images of the seabed habitats within Cape Bank rMCZ.Grab survey collecting PSA and benthin infaunal samples from seabed habitats within Cape Bank rMCZ. These data are archived with the Marine Environmental Data and Information Network (MEDIN) Data Archive Centres (DACs) including the British Geological Survey (BGS) DAC for geology and geophysics, The Archive for Marine Species and Habitats Data (DASSH) and the United Kingdom Hydrographic Office (UKHO) bathymetry DAC.The full site data package (excluding raw bathymetry) is also available on request from BGS.

This sampling and geophysical survey has been carried out by, Institute of Geological Sciences (IGS) now British Geological Survey (BGS) for BGS, the survey took place from August to December 1974 in the Bristol Channel, Irish Sea and English Channel on board the MV Whitethorn. The purpose was to collect data as part of a geological mapping programme. Sample data were collected using Drilling equipment,: Rock Gravity Corer, Sediment Gravity Corer, Vibrocorer and Shipek Grab. These data are archived by BGS. Details of the survey are contained in IGS Annual Report 1974 and IGS report 79/8.
