The Geological Survey of Northern Ireland, founded in 1947, is an office of the Department of Enterprise, Trade and Investment for Northern Ireland (DETI). The survey is responsible for providing a wide range of geological advice and information in support of planning, land use, environmental protection and natural resource assessment. We also carry out surveys to collect new data. Our customers include local and national government agencies, the private and educational sectors, and the general public.

The GSNI currently has 23 staff, of whom 17 are geoscientists and scientific support staff. The scientific staff are drawn from the British Geological Survey (BGS) under an agency agreement which allows the GSNI to draw on expertise in other parts of BGS. We are further strengthened by collaboration with the Geological Survey of Ireland and the Queen's University of Belfast.

The staff have a detailed knowledge of the geology of Northern Ireland, and have access to an unrivalled archive of geological data gathered during the last 150 years.
