Data from geophysical surveys in many South American and Caribbean countries carried out by the British Geological Survey for different agencies. The surveys range from regional gravity and airborne magnetic mapping to targetted surveys for mineral and water. Individual surveys do not yet have metadata entries: this entry describes a notional database that represents all geophysical surveys carried out within the region.

A collection of regional geochemical data, mainly from stream sediment surveys, gathered from many BGS overseas projects since 1960s. Some areas are well covered and well documented with data available digitally on CD-ROM. Projects from 1960s and 1970s generally have no digital data and information exists only in paper form.

Data from geophysical surveys carried out by the British Geological Survey in many countries in the Middle East, the Indian sub-continent and Indo-China for different agencies. The surveys range from regional gravity and airborne magnetic mapping to targetted surveys for mineral and water. Individual surveys do not yet have metadata entries: this entry describes a notional database that represents all geophysical surveys carried out within the region.

This document dataset contains original prints, on paper, sepia or film, of seismic reflection survey sections, dating from the 1960s. Most data are within the UK onshore area; although there are some UK near-shore and offshore (North Sea, Irish Sea) and foreign data. Most data were acquired for commercial hydrocarbon exploration and subsequently provided to BGS for use on specific projects. Some data were acquired by BGS and other public-sector bodies, e.g. BIRPS (British Institutions Reflection Profiling Syndicate), for academic research. This data set is a master set; copies must be used for interpretation purposes. Documents stored rolled in tubes, approximately 10 sections per tube, approx 850 tubes. The data are mostly concentrated in areas prospective for coal, oil and gas.

The Marine Maps and Chart Archive held by BGS contains maps created by BGS (the majority of which result from BGS offshore mapping projects) and also maps acquired from various other sources (e.g. UK Hydrographic Office and MCA Civil Hydrography Programme survey charts). The maps which date from the 1960s onwards are very variable in subject type and scale ranging from survey navigation to geological interpretation. The maps are primarily for the UKCS (United Kingdom Continental Shelf). The coverage of some map types is the entire UKCS whilst other have only regional or localised extent. The maps which are a mix of paper and digital are applicable to a wide range of uses including environmental, geotechnical, geophysical and geological studies. range of uses including environmental, geotechnical, geophysical and geological studies. Scanned maps can be viewed via the BGS maps portal http://www.bgs.ac.uk/data/maps.

Data from geophysical surveys in many African countries carried out by the British Geological Survey for different agencies. The surveys range from regional gravity and airborne magnetic mapping to targetted surveys for mineral and water. Individual surveys do not yet have metadata entries: this entry describes a notional database that represents all geophysical surveys carried out within the region.

Data on the physical properties (transmissivity, storage coefficient, porosity and permeability) of aquifers in England and Wales. Compiled by BGS staff from paper records of field and laboratory testing held by BGS, the Environment Agency and other organisations. Contains summary data on approximately 20,000 pump tests at over 2000 discrete locations. The majority of BGS and EA pump test data is included for both major and minor aquifers, but in minor aquifers this is complemented by data on specific yield. Laboratory determinations of porosity and permeability are limited to open file BGS data only. All data subject to similar processing and interpretation, but raw data highly variable.

The Marine Reports Archive held by BGS includes published and unpublished reports created by BGS and acquired from various sources. The reports which date from the 1960s onwards include the BGS Marine Reports Series, Marine Commercial reports and associated records, Palaeontology reports and other specialist reports. Examples of report types are data acquisition and processing reports, site investigation reports and interpretation reports. The reports are primarily for the UKCS (United Kingdom Continental Shelf). The coverage of some reports is the entire UKCS whilst other have only regional or very localised extent. The reports are applicable to a wide range of uses including environmental, geotechnical, geophysical and geological studies.

The collection, amounting to c.6,000 records, consists of reports and data relating to geochemical sampling, geophysics, drilling and field mapping deposited by mineral exploration companies dating from c.1960 onwards. Major accessions include records of Mineral Exploration Incentive Grant Act (MEIGA) and reports and plans of Exploration Ventures Ltd (EVL) relating to NE Scotland. Indexed in Land Survey Record Index Database (LSRI).

BGS has carried out geophysical surveys in many countries for different agencies. The surveys range from regional gravity and airborne magnetic mapping to targetted surveys for mineral and water. Individual surveys do not yet have metadata entries: this entry describes a notional database that represents all overseas geophysical surveys.
