Photos from the Near-surface Geophysics class (ERTH 325), Fall 2006
Glenn Spinelli, Assistant Professor of Geophysics

Above: Kyle Jones using a magnetometer to determine the extent and orientation of a buried basalt flow in Socorro Canyon.

Above: Resistivity surveying is not the most photogenic activity -- the best photo of the study area is from space. Students conducted a resistivity sounding to estimate the depth of Fort Stanton Cave.

Above: Students measuring a gravity anomaly to estimate offset on a normal fault separating down-dropped sedimentary rocks (left) from uplifted granite (right) in Arroyo del Tajo.

Above: After a long day making gravity measurements, a 3 foot long diamondback rattlesnake can really reinvigorate the class. Photo by Kyle Jones (he used a telephoto lens -- he wasn't crouched 18" from a rattlesnake ready to strike).

Above: John Morton at the bank of the Rio Salado, using an EM31 to look for differences in subsurface electrical conductivity and estimate the depth to the water table on the upstream and downstream sides of a cemented fault.

Above: Students using Ground Penetrating Radar in a dry channel of the Rio Salado. They used GPR to look for differences in the depth to the water table upstream and downstream from a cemented fault that is thought to act as a barrier to groundwater flow.

No photo from the seismic refraction survey the class did -- too much sleet and snow.
