Initial Findings of Tellus Border Project Revealed
Mairéad Glennon, Assistant Project Manager - Tellus Border Project


Minister for Natural Resources, Mr Fergus O'Dowd, T.D. unveiled the preliminary findings of the Tellus Border project on 5th February, 2013 at the Davenport Hotel, Dublin. Speaking to over 80 stakeholders from central and local government, research and the environmental, agriculture and mineral exploration sectors, Minister O'Dowd sais "The maps released today represent a significant body of work which characterises in great detail the geology and environment of the border region. Sustainable environmental management not only protects our environment but supports many sectors of the cross-border economy including agriculture and tourism".

Tellus Border data release

The Tellus Border project is an EU INTERREG IVA-funded mapping project that involves the collection of scientific data on soils, sediments, waters and rocks across the six border counties of Ireland (Donegal, Sligo, Leitrim, Cavan, Monaghan and Louth) and the integration of these with existing data collected in Northern Ireland as part of the Tellus project in 2007. The Geological Survey of Ireland is a partner in this cross-border initiative, which is led by the Geological Survey of Northern Ireland in Belfast. After the successful completion of the geophysical and geochemical surveys in Summer 2012, the three-year project is now in a data interpretation and mapping phase. Ray Scanlon, Acting Principal Geologist and manager of the Tellus programme at the GSI, said the Tellus Border team was pleased with the early release of the data: “We’re delighted to be able to deliver this data to our stakeholders some 10 months before the end of the project in December 2013. The early release of the airborne geophysical data and the preview of the geochemical data will allow researchers, planners, environmental managers and mineral exploration companies to start using the data from this flagship project straight away for the benefit of the environment and the economy”.

The airborne survey data, now available to the general public free of change, has revealed extraordinary new detail to regional geological features which extend throughout the border region. New information on subsurface structures is already helping to improve and update the Geological Survey of Ireland’s existing geological maps, which support sustainable planning countrywide. Data is available to view and download on the Tellus Border website

The launch event also saw a preview of the geochemical data, which will be released later in 2013 following continuing quality checks and interpretation. The data will reveal important natural and man-made influences on the soil and water chemistry of the area, significant for managing the environment and optimising agricultural productivity. Forty seven soil geochemistry maps are now available to view online with the Tellus Border online viewer.

A conference will be held in October 2013 to officially close the project and present the full findings from the survey and accompanying academic research projects. To register for notifications for upcoming data releases, please email your details to
