Index to the reports of work carried out by the BGS and its precursors. The index was set up in 1988 and has worldwide coverage. These reports cover a wide range of scientific and technical disciplines and were produced for a variety of purposes. The reports are not published but copies can be provided on demand subject to any restrictions. All registered Technical Reports held in collection are indexed. Start date of digital index circa 1988. Technical reports date from circa 1950 onwards.

[THIS DATASET HAS BEEN WITHDRAWN]. This dataset contains calculated return rates for five seabird species from representative colonies on the Isle of May, off the East coast of Scotland. Annual return rates are measured as the number of individually colour marked individuals seen in any one year that were also observed in the previous year for the Atlantic puffin (Fratercula arctica), common guillemot (Uria aalge), razorbill (Alca torda), European shag (Phalacrocorax aristotelis) and black-legged kittiwake (Rissa tridactyla). Not every individual is seen in any one year and the data set does not take into account those missed in any previous years hence these data are not to be treated as survival estimates. The Isle of May long-term study (IMLOTS) aims to identify the impact of environmental change on seabirds and their associated ecosystems. Understanding the mechanisms underlying variation in seabird population size requires a thorough knowledge of demographic parameters, namely birth rates, death rates, immigration and emigration. The effects of environmental change are likely to be different according to which demographic parameter or life history stage is being considered. This complexity means that only long-term monitoring, such as that carried out on the Isle of May, will allow us to understand the functioning of bird populations and their responses to environmental change.

The Land Survey Record Index was set up c.1988 to provide a digital database index to records and archives held by the Land Survey in Scotland and Northern England and contains over 46,600 records. Finding aid to the following record groups/data sets, is provided through a application query interface: Site Investigation Records (SE); Land Survey Archives (LSA); Land Survey Records (LSR); Mineral Resource Records (MR); Additional Information Files (AI); Enquiry Record Files (EE; EN); Opencast Coal Sites (OC).

Index to acquisitions and donations of all types of geological record data. This information has been received from a variety of external organisations including public bodies and commercial concerns. The Oracle index was set up in 1988 and holds basic index information about the donor and the donation. The index has been expanded in 2009 to include other sections of BGS and covers all their donations. The majority are from Great Britain.

The Borehole Geology database holds downhole lithological / lithostratigraphical data (with unit-bound lithological properties where appropriate) for boreholes identified within the Single Onshore Borehole Index (SOBI), which covers onshore and nearshore Great Britain. The database can store multiple interpretations for each borehole and properties assigned to each coded lithological unit. Available borehole geology properties include porosity, Munsell colour, grainsize, water struck, etc, and other valid property-types can be included when/if required.

Index to reports of site investigations produced by external organisations carried out for all forms of site investigation. The Oracle index was setup in 1988 and covers the whole of Great Britain, all site investigation reports are indexed but the level of detail in the index for each record may vary. The reports date back to the 1950's and may contain information on boreholes, trial pits, laboratory tests and chemical analyses etc.

Data from the flight 3 of 17 from the NASA/NOAA aircraft campaign based in Darwin, Australia in January and February 1987. Designed to investigate mechanisms of equatorial stratosphere-troposphere exchange. Measurements include trace gases and aerosol in cloud free and cloud dominated conditions. This dataset is public.
