Geophysics Field Camp Section headingSample content Introduction Why this site? Purpose of resistivity/conductivity measurements: Expect to see freshwater/saltwater interface (describe expected conductivity contrast) May see tar mats, buried tar mats (describe expected conductivity contrast) Ground truthing Methods Equipment: AGI Supersting R8 resistivity meter Field geometries: 28 electrodes, 1-m spacing Acquisition parameters: dipole-dipole and inverse Schlumberger array geometries, 2 cycles/reading Processing software: Res2dinv Processing steps: Editing data (what % removed, why?), inversion parameters, number of iterations,… Results Map, position information Describe data volume, data quality Raw data (if appropriate) = pseudosection Processed data = inversion Xsection(s) Discussion On processed data image (preferably second copy), add notations with geologic interpretations Comparisons with ground truthing Comparisons with other methods (if available) If appropriate, what didn’t work and why Strengths and Limitations (of this method) Finer spatial resolution than EM-31 or EM-34 (be quantitative if possible) Labor-intensive (xx hrs for xx meters of profile) Assessment

Field Geophysics Workshops Latin America

Field Geophysics Workshops  Case studies for subsequent students with access to site but not to equipment  Critical to find sites with some ground-truthing

Field Geophysics Workshops
