The Geophysical Borehole Log index provides details of hardcopy geophysical logs known to BGS. The index provides the storage location of the logs and details of the format they are available in, eg. paper, at a scale of 1:200. The data is updated when new data becomes available. Contains most geophysically logged bores known to BGS National Geological Records Centre. Scattered distribution of boreholes, locally dense coverage, few logs from Scotland.

This dataset is an archive of original data for the geophysical logging of boreholes drilled by the National Coal Board (NCB) and its successor, British Coal Corporation (BCC). Data coverage is UK wide and dates from the 1970's to the privatisation of the coal mining industry, in 1994. The dataset includes approximately 2000 field data recording tapes and processed data tapes. The processed data tapes are at various stages of processing and consist of edited data and computed (CSU) data (not available for all boreholes). The data are kept as archive copies. The data are owned by the Coal Authority (CA), as successor to the NCB and BCC, BGS being the custodian under an agreement with the Coal Authority. No full catalogue or index available yet.

Contains most digital geophysically logged bores known to BGS National Geological Records Centre. Scattered distribution of boreholes, locally dense coverage, relatively few logs from Scotland & Central Wales, increasing data density on UK continental Shelf.

The cored, seismic monitoring borehole was drilled between 19 November and 12 December 2018 to 199m producing a core of 102 mm diameter. The borehole was wireline logged in December 2018 and a string of 5 seismometers were installed in February 2019. A range of fluid, water and core samples were taken during the drilling process. The borehole information pack- final release contains a range of logs on the core as well as images and scans of that core, these data were acquired in the first half of 2019 and late 2020/early 2021. The final data release for GGC01 includes: 1. UKGEOSGlasgow_GGC01_Final.zip file that includes the majority of the various data files, including files from the intermediate and initial data packs. 2. UKGEOSGlasgowGGC01_slabbedhighresimages.zip that contains the slabbed core optical images, 51GB in size. 3. Intermediate Borehole Information Pack - Part Two, high resolution whole core optical and radiographic images https://doi.org/10.5285/0b49f25b-a5d6-401c-98ff-397ad9ee9ed1 71GB in size, already released.
