The Tellus survey is a national programme to gather geochemical and geophysical data across Ireland – in other words, to examine the chemical and physical properties of our soil, rocks and water.
Tellus is undertaken by Geological Survey Ireland and is funded by the Department of Communications, Climate Action and Environment. All data from Tellus is 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.
To date, Tellus surveying has been completed in Northern Ireland (2004–2008) and the border region of Ireland (2011–2013). Tellus airborne surveying has been completed in the north midlands region of Ireland (2014–2015), the eastern midlands region (2015), the west of Ireland (2016–2017) and most recenetly in Limerick, north Tipperary and west Cork (2018–2019). The Tellus airborne geophysical survey has now mapped 60% of the country.
From late June until late autumn 2019, the Tellus aircraft will move to the south east of Ireland; into counties Carlow, Wexford, Wicklow and neighbouring parts of south Kildare, south east Kilkenny and Waterford.
The Tellus ground survey will commence fieldwork in late July 2019. The fieldwork will involve soil sample collection in predominantly rural areas across the north midlands region of Ireland. The work is to be carried out by end September 2019.
Tellus has established a Product Development
workstream in order to produce more focused, user-centric data products, the need for which has been identified through stakeholder consultation, independent reviews of Tellus and government policy. Product development is undertaken under five main themes: mineral prospectivity, smart agriculture, environment and health, climate action and education.
