Field notebooks,maps, field sheets etc for Regional gravity observations on the UK mainland, Northern Ireland, offshore islands, tidal estuaries and seabed. Most of the surveys were carried out by the BGS but the database includes data originally acquired by other organisations and subsequently given to the BGS to be managed as part of the national archive. Complete coverage of the UK mainland with a station density of 1-2 stations per square kilometre.
