The paper that has excited me the most at the International Symposium on Archaeometry this week in Tampa is:
Chase, Arlen F.; Chase, Diane; Weishampel, John
University of Central Florida
This technology has been around, but this application hit me over the head as a stunning application to archaeology.
This (coincidentally) was in the session I co-organized on Field Methods, which used to contain many archaeological geophysics papers, but now has more of a mix, as the geophysics papers seem to be going to other venues.
The work of the Chases and colleagues at Caracol (source of photo) was nicely described this week in a New York Times article. I'd like to think the story was picked up from the ISA.
