  • The TellusSW project acquired airborne geophysical data for the counties of Cornwall and parts of Devon and Somerset during the second half of 2013. The maps of the geophysical data and their derivatives are provided to facilitate spatial comparison with, and modelling of, the soil, geological and environmental aspects of the data. The survey comprised a high resolution magnetic/magnetic gradient survey combined with a multichannel (256 channel) radiometric survey. The survey was carried out using 200 m (N-S) line separations at a mean elevation of 91 m. The survey provided 60,323 line-km of data.

  • The joint PHE-BGS digital Indicative Atlas of Radon in Great Britain presents an overview of the results of detailed mapping of radon potential, defined as the estimated percentage of homes in an area above the radon Action Level. The Indicative Atlas of Radon in Great Britain presents a simplified version of the Radon Potential Dataset for Great Britain with each 1-km grid square being classed according to the highest radon potential found within it, so is indicative rather than definitive. The joint PHE-BGS digital Radon Potential Dataset for Great Britain provides the current definitive map of radon Affected Areas in Great Britain.

  • This service is an INSPIRE download WFS service, providing UK onshore bedrock geological data at 1:625 000 scale. This map data is collected as part of an ongoing BGS project: Digital Geological Map of Great Britain (DiGMapGB). GeoServer software is used to provide this WFS service. This service is delivering MappedFeatures specified by GeologicUnits, the geological history of which is recorded by GeologicEvents.

  • This dataset (GSE_REFERENCES) is a list of specimens held in the Type and Stratigraphical Collection of Scotland and Northern England, and the publications in which they are featured or illustrated. This database along with GSE_SPECIMENS (Index To The UK (North) Type And Stratigraphical Collection Of Fossils) and to some extent SMITH_GSE (Index To Specimens Transferred From The John Smith Collection To The UK (North) Type and Stratigraphical Collection) are the digital equivalents of the analogue card index (held in BGS Edinburgh).The latter contains c.16k records, of which perhaps 25% have now been transcribed. The MS Access database BGS_GSE_REFS presently contains 431 records (but does not include specimens from the John Smith Collection). This represents an unknown, but probably small, proportion of the Type and Stratigraphical Collection of Scotland and Northern England featured in publications. The database links with GSE_SPECIMENS, and can also provide species, authors and nomenclatural status. Many of the publications referred to are held in an extensive paper reprint collection.

  • 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.

  • Magnetograms are used to record variations in the strength and direction of the Earth’s magnetic field. In the UK measurements were made at eight long-running observatories; Abinger, Eskdalemuir, Falmouth, Greenwich, Hartland, Kew and Lerwick. Original paper magnetograms were recorded using photographic techniques at Kew, Greenwich, Abinger, Hartland, Eskdalemuir and Lerwick Observatories. The magnetogram collection, one of the longest running geomagnetic series in the world, provides a continuous record of more than 160 years of UK measurements. These magnetograms start in the 1840s and end in 1986 at which time digital recording of the magnetic field took over and magnetograms can be produced by computer graphic. The plots show variation in the Earth's magnetic field, typically over a 24-hour period. The collection is a valuable, partly untapped data resource for studying geomagnetic storms, space weather and the evolution of the Earth’s magnetic field. The magnetograms provide insight into: • the Earth’s outer core: long-term change (years to centuries) in the dynamo that sustains our magnetic field • space weather: short-term changes (seconds to days) in near-Earth space and on the ground • space climate: long-term change (decades to centuries) in solar activity and consequences for Earth’s environment All the above have an impact on human activities. For example, bad space weather affects technologies that we increasingly rely on, such as electrical power and GPS networks. In January 2009, the BGS began a project to capture high-quality digital images of the magnetogram collection to provide a back up to the photographic paper originals. The images captured so far are available to search online. Scientists and the general public around the world can now gain easy access to this historical dataset.The programme of work to complete the magnetogram digitisation is ongoing and more will be added, observatory by observatory.

  • The register lists Lower Palaeozoic microfaunas (including "small shelly" faunas), but occasionally mentions small trilobites and various fragments. SAQ1-259 are used, although several numbers have no details assigned to them. Sample number, sheet number, NGR, fossil identification, borehole names & depths are given.

  • In March 2010, the Scottish CCS (Carbon Capture & Storage) Consortium began an extensive Front End, Engineering and Design (FEED) study to assess what would be required from an engineering, commercial and regulatory, perspective in order to progress the CCS demonstration project at Longannet Power station in Scotland through to construction. The study yielded invaluable knowledge and the resulting material are available for download here. This section of the report is provided as a support document to the tangible learning and documentation contained within the FEED Close Out Report and accompanying appendices. The experiential learning of the teams working across key functions of the FEED study was captured in guided discussions halfway through FEED to establish the specific challenges, successes and learning of the various workstreams involved in undertaking FEED. Representatives from all the workstreams were brought together in December 2010 for a Consortium-wide Lessons Learned Workshop to capture specific, discrete lessons that could benefit future CCS FEED studies in the UK and abroad. Five key themes emerged consistently across workstreams: Ensuring an appropriate mobilisation period Early engagement with key stakeholders Cross-Consortium communication to present an integrated Consortium Recognising restrictions imposed by the bounds of a competitive procurement Working with uncertainty across regulation, scope, budget and political will Workstream specific learning outcomes are summarised in the main report, with detailed examples included in the appendices. The technical and communication workstream appendices both contain examples of actual documents used during the ScottishPower Consortium FEED (National Grid CCS staff training material and the ScottishPower Consortium Communications Strategy) that were considered useful for future CCS project Developers. The appropriate summary section from the Feed Close Out Report can be downloaded as a PDF below (Lessons learned.pdf). The main text of the FEED Close Out Report, together with the supporting appendix for this section can be downloaded as PDF files.

  • Carbon capture and storage is a mitigation strategy that can be used to aid the reduction of anthropogenic CO2 emissions. This process aims to capture CO2 from large point-source emitters and transport it to a long-term storage site. For much of Europe, these deep storage sites are anticipated to be sited below the sea bed on continental shelves. A key operational requirement is an understanding of best practice of monitoring for potential leakage and of the environmental impact that could result from a diffusive leak from a storage complex. Here we describe a controlled CO2 release experiment beneath the seabed, which overcomes the limitations of laboratory simulations and natural analogues. The complex processes involved in setting up the experimental facility and ensuring its successful operation are discussed, including site selection, permissions, communications and facility construction. The experimental design and observational strategy are reviewed with respect to scientific outcomes along with lessons learnt in order to facilitate any similar future. This is a publication in QICS Special Issue - International Journal of Greenhouse Gas Control, Peter Taylor et. al. Doi:10.1016/j.ijggc.2014.09.007.

  • Carbon capture and storage (CCS) is a way of possibly reducing impacts from fossil fuel emissions by injecting large volumes of carbon dioxide into appropriate geological formations. Some of the existing and proposed storage sites are below the seabed. In order to better understand the environmental impacts of leaks from a sub-surface marine storage facility and to investigate how leaks or potential leaks could be detected, a world-first experiment consisting of an artificial carbon dioxide release from below the seabed was undertaken in 2012. The need for accurate deployments and re-deployments of measurement equipment, the retrieval of biological and sediment samples within very specific areas of the release site and the in-situ measurement of escaping gas volumes, necessitated an extensive scientific diving program. Diving was also employed to determine the most optimum experimental site prior to the program’s initiation and to map the site prior to the beginning of the experiment. Diving also proved to be an essential tool (through observation, photography and videography) in recording the progress of the experiment and the physical interactions and impacts arising from managing a large multi-partner, multi-discipline research program.
