Areas of Expertise

� Accuracy: Attention to accuracy of GPS collocated data with awareness of and correct translation of geospatial coordinates between older and newer national map projections including AGD66, AGD84, GDA94 and WGS84

� Quality Control: Consistent checking and QC of profile and gridded geophysical data on

daily or regular basis especially before survey crew departure from site and finalisation for inclusion in survey reports

� Presentation: Careful choice of cartographic presentation of boundaries, line & point symbols, geophysical data grids including TMI, RTP, 1VD & 2VD and text so that fonts and colour schemes are easily understood by the map user

Significant Achievements: Ground Gravity Survey, Mauritania, West Africa; April – July 2013 Mine site survey as crew leader from planning to completion, supervised acquisition and processed GPS collocated gravity data with QC, liaison with on-site geologist during operations, produced final gravity maps; including derivatives such as 1VD & 2VD grids and wrote survey report. A fuller and more accurate understanding of mineralisation and the location of potential new gold deposits was achieved. Ground Gravity Survey for study of paleo channels, Katanning, WA; Mar 2012 Acquisition of GPS gravity data, processing and geological depth to basement modelling to map the actual depth of the paleo channels by rock density contrast for better management of ground water extent at depth Helicopter Gravity Survey, Balladonia & Norseman, W A; Sep – Oct 2009 Processed GPS gravity data with QC using Bouguer gravity formulae supplied by AGSO, wrote final survey report including Bouguer gravity maps. This survey covered 2 Australian 1:250 000 map sheets for addition to the AGSO national geophysical survey. Geological interpretation of Airborne Magnetic Data , Ghana & Nigeria, Africa; Aug 2008 – Nov 2009 Depth to basement analysis with Euler and Werner deconvolutions on airborne magnetic data for modelling of structural geology to contribute to the production of a national geological atlas for each country Airborne Magnetic and Radiometric Survey, Papua New Guinea; Dec 2005 – Jun 2007 Helicopter survey operator in the Western Highlands of Papua New Guinea, acquisition, field processing and QC of GPS collocated data on national survey with 400m or 500m spaced survey lines. Survey funded by the European Union to greatly improve the accuracy of existing geological mapping to benefit existing mining operations and assist in future economic development of national resources National Atlas of Forestry Commission Assets, UK; Aug 1985 – Dec 1995 Accurate transfer of boundaries of forestry plantations from paper title-deed plans with digitisation on light table to a GIS database, assigning attributes for the national atlas of forestry plantations
