Tellus is a ground and airborne geoscience mapping programme, collecting chemical and geophysical data that will inform the management of Ireland’s environment and natural resources.

Tellus is undertaken by the Geological Survey of Ireland and is funded by the Department of Communications, Energy and Natural Resources. All data from Tellus are made available free of charge online
 at, including:

Tellus involves two types of surveying – airborne geophysical surveying using a low-flying aircraft and ground-based geochemical surveying of soil, stream water and stream sediment. Surveying activities are currently paused for winter 2015 and are set to restart in early 2016.

The sample archive at the Geological Survey of Ireland is available to researchers on an application basis.

The Tellus team would be pleased to hear from potential partners interested in collaborative research and funding bids for future phases of surveying.

To date, Tellus surveying has been completed in Northern Ireland (2004–2008), the border region of Ireland (2011–2013), the north midlands region of Ireland (2014–2015) and most recently the eastern midlands region (2015). Longer term, Tellus aims to complete surveying the entire island of Ireland on a phased basis, completing 50% by end 2017.
