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.
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 for 2016 consist of airborne surveys in Waterford (May 2016) and Galway (June – autumn 2016), and a geochemical survey in the West of Ireland (May-autumn 2016).
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.
Tellus is using harmonised, systematic surveying techniques across entire regions of the island of Ireland, producing seamless maps for a variety of end-users.
The coupling of airborne geophysics and ground-based geochemistry provides a richness of data which puts Ireland amongst the top countries in the world for the quality, breadth and availability of geoscience information.
