Registers of macrofossils in 127 volumes, covers the whole of the UK. Within each volume, data is arranged sequentially usually by collectors no. The data set began with the first Palaeontologist in the Geological Survey of Great Britain.

This map is part of the open-loop ground source heat pump screening tool and shows where suitable subsurface conditions exist in England and Wales for open loop GSHP installations of >100kW heating/cooling output .

Seabed geology of the UK’s continental shelf, fine-scale maps providing detailed and accurate characterisation of the seabed geology, integrating substrate geology, structural geology and seabed geomorphology. Areas covered Anglesey, Bristol Channel, Dorset, East Anglia and Offshore Yorkshire. Mapping is based primarily on high-resolution bathymetry data produced by the UK Civil Hydrography Programme (CHP). Analysis and interpretation are further informed by secondary data and information resources, including; acoustic backscatter, physical samples (for example grabs, cores and boreholes), seismic data, academic and publicly accessible industry data and literature, and previous BGS mapping (onshore and offshore). The CHP is administered by the Maritime and Coastguard Agency (MCA), with technical oversight, data validation and onward charting undertaken by the UK Hydrographic Office (UKHO). The new fine-scale BGS Seabed Geology mapping comprise three complimentary components (or layers); substrate geology: distribution of bedrock and superficial geological units interpreted to be dominant within the top 1 m below seabed, structural geology: principal structural features such as faults and folds observed at rockhead and seabed geomorphology: physical morphology and interpreted geomorphic character of the seabed. These detailed geological digital maps are intended as enabling resources to better inform multiple offshore activities, research, and management of the marine environment. However, the seabed is a dynamic environment, where sediments may be in constant motion and sediment waves may migrate across the seafloor, burying or exposing the underlying hard substrate. Therefore, this data should not be relied on for local or site-specific geology. The mapping presented has been developed at a scale of 1:10 000 and should not be used at finer scales. Further detail on the mapping process and dataset characteristics are described within individual dataset user guides.

**Now superceded by Geoscience Imagebase**Digital index to the British Association for the Advancement of Science (BAAS) Geological Photographs. This collection of around 8,000 photographs dating between 1861 and 1948 is held in the BGS Library on deposit from the BAAS. The Irish photographs are held in the Ulster Museum in Belfast.

This dataset is part of the infiltration SuDS map and infiltration SuDS GeoReport. It has been developed to help inform planning decisions. This dataset shows the permeability of the bedrock for the purposes of determining whether the installation of infiltration sustainable drainage systems is possible. It differs from the permeability indices dataset in the following ways: a score field has been added to polygons, polygons of equal attributes have been merged, a short and detailed description and an advice and layer ID field has been added.

Annual means of the geomagnetic field vector components from observatories around the world, from 1840 to the present day. At present there are about 160 observatories. These data are useful for tracking changes in the magnetic field generated inside the Earth. Data are produced by a number of organisations around the world, including BGS. Data are available in plain text from www.geomag.bgs.ac.uk. This data is connected to other geomagnetic data sets, but can be used without reference to them.

**No longer exists - now part of GeoSure**An assessment of the potential for a geological deposit to collapse under a critical load. A characteristic usually of loess or loessic material. The methodology is based on BGS digital stratigraphic linework and expert knowledge of the behaviour of the formations so defined.

Reference books, produced to accompany many of the 1:50 000 scale (district) maps, which describe the extent, nature and structure of the rock strata of the district. They often also include details of the geophysics, geochemistry, hydrogeology and economic geology of the district.

Scanned images of the records of onshore Great Britain (or near shore) site investigation reports held in the BGS archives in paper, microfilm or digital format. The entire collections in BGS Edinburgh have been scanned, but in BGS Keyworth currently only new reports received since 2002. Scanning started in 2002 and is ongoing with new records being scanned and added to the collection. Images are stored in TIFF format (Tagged Image File Format). Indexed on the site investigation database and the boreholes within the report, and their images, are associated via the borehole database.
