The latest phase of the Tellus programme collected new airborne data within the counties of Dublin, Meath, Kildare, Wicklow, Offaly and Laois in the Republic of Ireland (ROI) and is collectively referred to as block A1. Surveying was carried out between June 2015 and October 2015 by Sander Geophysics Ltd (SGL). Previous airborne geophysical surveys were carried out across Northern Ireland (Tellus) in 2005 and 2006 (Beamish et. al, 2006), parts of counties Cavan and Monaghan in the ROI (Kurimo, 2006), counties Donegal, Leitrim, Sligo, Cavan, Monaghan and Louth as part of the EU INTERREG IVA-funded Tellus Border Project (Hodgson and Ture, 2012) and across counties Roscommon, Longford and Westmeath as part of the Tellus North Midlands project (Hodgson and Ture 2015). All surveys measured magnetic field, electrical conductivity and gamma-ray spectrometer data (primarily potassium, thorium and uranium). This report summarises the main operations from the latest A1 survey and discusses the processing of the acquired data and its merger with existing datasets to produce seamless merged geophysical datasets.
