    The BGS GeoSure Shrink Swell 3D data is a regional hazard susceptibility map that identifies areas of potential shrink–swell hazard, in three dimensional space, at intervals down to 20m in the London and Thames Valley area. Shrinking and swelling clays can change volume due to variation in moisture, which can cause ground movement that may affect many foundations. The data provides an indication of variation in Volume Change Potential (VCP) of shrink-swell clays and is classified on an A-E (low to high) range of hazard susceptibility. BGS GeoSure Shrink Swell 3D for London is part of the BGS GeoSure range of natural subsidence products. It is derived from the BGS Geology 50k data, the BGS London Lithoframe 3D model and the GeoSure v7 Shrink-Swell layer.

    The UK Geoenergy Observatories (UKGEOS) Glasgow 3D coal mine model outputs, created by the British Geological Survey, provide a semi-regional overview of the depth and extent of surveyed and probable coal mine workings, plus stone and coal roads surveyed within the mines. The model allows users to visualise the surveyed and probable coal mine workings to be found beneath this part of Glasgow, applicable at a scale of around 1: 25,000 to 1: 10,000. The data is supplied as grids, triangulated surfaces over a 5 by 4.15 km area, with the depth range to around 300 m below Ordnance Datum. The mine extents are ‘cut out’ of the UKGEOS Glasgow pre-drill bedrock model. This model describes both surveyed (recorded on mine abandonment plan) and probable coal mine workings before the UKGEOS Glasgow boreholes have been drilled, and was used to inform the expected sequence on drilling. Further details and model limitations can be found in the accompanying metadata report http://nora.nerc.ac.uk/id/eprint/522737

    The UK Geoenergy Observatories (UKGEOS) Glasgow superficial deposits GSI3D model outputs, created by the British Geological Survey, provide a semi-regional overview of the depth, thickness and extent of glacial and post-glacial lithostratigraphic units above rockhead. The model allows users to visualise the likely subsurface sequence to be found beneath this part of Glasgow, applicable at a scale of around 1: 25,000 to 1: 10,000. The data is supplied as grids and shapefiles over a 7 by 4.15 km area, with the depth range to around 40 m below Ordnance Datum. This model describes an interpretation of the shallow geology before the UKGEOS Glasgow boreholes have been drilled, and was used to inform the expected sequence on drilling.

    The folders GMPKU2311, GMPKU3089, ELISN108-343 and ELISN31-5 contain data from X-ray tomographic analyses of fossil embryos and post-embryonic stages as described: There is one data folder provided for each specimen, each containing the following: - Raw data: zip archive containing the raw scan data (.tif image stack). - Working files: zip archive containing the segmented slices (.tif image stack exported from Avizo labels). - Avizo project: the Avizo .hx project file. - Avizo labels: the Avizo .am labels file, containing the segmentation information. - 3D model: the 3D surface computed from the segmented labels data (.stl file). In the case of GMPKU2311 only the raw data and 3D model file are provided, as the surface was computed directly from an isosurface of the specimen in Avizo. The individual slices (.tif images) can be viewed with standard graphics software, and the datasets can be studied in 3D using tomographic reconstruction software such as Avizo (www.vsg3d.com/), Spiers (www.spiers-software.org/), VG Studio Max (www.volumegraphics.com) etc. The Avizo project and label files (.hx and .am files) require Avizo software (www.vsg3d.com/) to be opened. The 3D models (.stl files) are widely compatible with 3D freeware packages such as MeshLab (http://meshlab.sourceforge.net/) or Blender (https://www.blender.org/), or with proprietary software, e.g. Avizo (www.vsg3d.com/), Geomagic (http://www.geomagic.com/en/), Mimics (http://biomedical.materialise.com/mimics). The files relate to the following publication: Dong, X.; Vargas, K.; Cunningham, J. A.; Zhang, H.; Liu, T.; Chen, F.; Liu, J.; Bengtson, S. & Donoghue, P. C. J. 2015. Developmental biology of the early Cambrian cnidarian Olivooides. Journal of Paleontology.

    The UK Geoenergy Observatories (UKGEOS) Glasgow bedrock model outputs, created by the British Geological Survey, provide a semi-regional overview of the depth and extent of bedrock lithostratigraphic units, coals and faults. The model allows users to visualise the likely subsurface sequence to be found beneath this part of Glasgow, applicable at a scale of around 1: 25,000 to 1: 10,000. The data is supplied as grids, triangulated surfaces and shapefiles over a 5 by 4.15 km area, with the depth range to around 350 m below Ordnance Datum. This model describes an interpretation of the bedrock geology before the UKGEOS Glasgow boreholes have been drilled, and was used to inform the expected sequence on drilling. Further details and model limitations can be found in the accompanying metadata report http://nora.nerc.ac.uk/id/eprint/522737.
