Basic Principles of Survey Design
area of data acquisition must be large enough to capture the anomaly
sampling interval must be sufficiently fine (for a dipole at least 3 points per half-width
relationship between halfwidth and depth of burial for a dipole
Use Applet examples and buried prism to get these points across. In addition we could put together a list of some specific things they could do with the app to gain insight.
In general, we want to use a numerical modelling package to simulate the expected response and use that to help determine sampling strategy.
Again, we can provide a list of things they might explore (sheets, elongated bodies, small object at depth etc.);
Instrumentation (some background in GPG is good)
Options: total field magnetometers (proton precesson, Cesium vapor)
magnetometers (fluxgate)
ganged systems like that for UXO
borehole magnetometers
Field acquisition:
Generally collect data in lines (particularly airborne data)
On ground line spacing is ideally same as station spacing
Need a base-station
Comment: Instrumentation could come first but from the viewpoint of understanding the survey, and the fact that we are following from Basic Physics, having it in #2 position works
