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, Climate Action and the Environment. 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 2017 consist of airborne surveys in Co Mayo and Co Donegal, and a geochemical survey in the central west of the Midlands of Ireland. Both surveys will be commencing in early spring and will finish in autumn 2017.
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.
