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).

New acquisitions of all forms of geological data received from external organisations are recorded in the accessions database and the digital or analogue data itself is then available to users. Data is in the form of reports, plans and digital information. This information comes from a wide variety of sources, including public bodies and agencies and commercial organisations. The data itself will be incorporated into existing corporate collections or may form a new collection in its own right. The rate of transfer will depend on priorities and requirements of both internal and external users. Data is continuously removed from the collection, all except recently received material will have been processed.

Data from the flight 8 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.

Data from the flight 2 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.

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.
