Geological Survey of Northern Ireland (GSNI)

The Geological Survey of Northern Ireland (GSNI) is part of the Department for the Economy Northern Ireland (DfE). It is staffed by scientists of the British Geological Survey (BGS) under contract to DfE, which allows GSNI to call upon expertise from within other parts of the BGS. GSNI also advises other Northern Ireland government departments and liaises closely with the Geological Survey of Ireland (GSI).

GSNI provides geoscience information and services to inform decision making. We hold an extensive archive of maps, boreholes and site investigation reports; detailed urban and regional geochemical and geophysical data, and published books, memoirs and reports.
