A map-based index to offshore datasets that we have collected or have obtained from other sources. Boreholes, seabed samples, geology, geophysics, hydrocarbon wells...


Onshore GeoIndex

GeoIndex example

A map-based index to onshore datasets that we have collected or have obtained from other sources. Boreholes, collections, earthquakes, geochemistry, geology, geophysics...


Groundwater levels timeline viewer

Groundwater levels timeline viewer

Map viewer providing online access to a timeline of monthly groundwater levels across the UK from 1970 to present.


Hydrogeology viewer

UK hydrogeology viewer

The UK Hydrogeology viewer indicates aquifer potential in generalised terms to show high, moderate and low productivity aquifers, plus rocks with essentially no groundwater. The map's 1:625 000 scale data may be used as a guide to the aquifers at a regional or national level, but should not be relied on for local information.


London Earth
