Argus is the name of a scientific research project, that investigated crop circles. In the summer of 1992, Project Argus investigated one of the
most remarkable mysteries of the century, the sudden and
baffling appearance of hundreds of huge, magnificent shapes -
dubbed "crop circles" - in the fields of England each summer.
My method when measuring magnetic flux density was to record the output of the Bartington
meter, applying to its three sensors (in the x, y, and z directions) the "root of the sum of the squares"
method. When measuring susceptibility I used the output from the Bartington meter for measurements on
site, employing either the MS2 F probe or its D loop, according to circumstances. In several cases soil
samples were also taken. using the Bartington MS2 B36 sensor. The samples (and controls) were
powdered and then placed in 10cc holders for laboratory testing.
