Conducted by the Geological Survey Ireland (GSI), the Tellus survey collects geochemical and geophysical data on rocks, soil and water across Ireland.
The latest phase of the survey involves an aircraft flying at a low height over western County Donegal, and will be in the air from March 2017 to late autumn 2017 (weather permitting). The Tellus website – www.tellus.ie – is updated weekly with the planned flight schedule.
The aircraft will fly at a low level of 60 metres over rural areas (approximately eight times the height of a standard two storey house), rising to 240 metres over urban areas.
The sound of the plane is similar to that of a passing lorry; however it may startle sensitive livestock such as horses, pedigree cattle, sheep-in-lamb and poultry flocks.
As it is vital to raise public awareness of the project, particularly amongst farmers and animal owners - the Tellus team is delivering an ongoing communications campaign across the regions.
If you have any concerns about the survey, particularly if you own sensitive livestock, or if you are interested in finding out more about the project, you can contact the Tellus Freephone information line on 1800 303 516 or visit www.tellus.ie. You can also follow Tellus on twitter, @TellusGSI
