Graphics/Imagery:

Filtered magnetic susceptibility data reveals linear trends possibly representing structures and garden plots

Close-up of magnetic susceptibility data shows lineations that may correspond with features as well as edges of garden plots.

 

  

 

Survey Type: Electrical Conductivity;

Instrument: Geonics, Ltd. EM-38, quadrature phase; Sampling Interval: .5 m x .5 m; Prospecting Depth: 1 -1.5 m; Area Surveyed: 9,600 sq m; Date of Survey: Sept 29 - Oct 3, 2003; Land Cover Type: High Chihuahuan desert; Ground Truthing: To be conducted in fall 2004;

Graphics/Imagery:

Circular trends appear in the conductivity data possibly representing adobe pitstructures

Close-up of conductivity data and GPR data showing an adobe structure. Adobe, which is highly conductive is represented by black. Why does the entire roomblock visible in GPR (made of adobe) not appear in conductivity?
