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.
