Quality control of airborne geophysical data from the EU Mining Sector Support Programme, Ghana

摘要

On 2 December 2002, EU Commissioner Poul Nielson onbehalf of the European Development Fund signed a €40 million grant to the Ghana Government. The purpose of thisgrant was to finance a Mining Sector Support Programme(MSSP) that covered a broad spectrum of geoscientificprojects and other projects aimed at an overall strengthening and modernisation of Ghana’s mining sector. One ofthe major components was collection and interpretation ofairborne geophysical data contracted to the two commercialgeophysical companies Fugro Airborne Surveys and Geotech Airborne Ltd. The Geological Survey of Denmark andGreenland (GEUS) was contracted to perform the qualitycontrol (QC) of the airborne geophysical data collectionand processing in a separate MSSP project (No 8 ACP GH027/37). The initial Provision of quality-control servicesto the Airborne Geophysical Survey required GEUS to beon site in Ghana for 22 man-months; an expansion of theprogramme and various circumstances (see below) resultedin a total of 37.25 man-months before the project was completed in January 2010. The Danish National Space Centerwas subcontracted by GEUS to perform part of the QC ofgravity data acquisition and processing. The QC project wasreported by Thorning et al. (2010).
