Title: Remote detection of chlorophyll fluorescence of sagebrush, Gold Run District, Humboldt County, Nevada
Description: This is not a book. It is a U.S. Geological Survey Open File Report written by me, Arnold F. Theisen, on the "suggestion" from my Branch Chief. The data were disappointing to say the least. When I finally received permission to conduct the field research data collection trip, it was late in the year, night-time temperatures were very low in the desert and the sagebrush had mostly gone dormant. Not a very good time to be measuring their chlorophyll fluorescence. The idea was to use that parameter to determine whether plants inside and outside of a known gold area would be changed by the uptake of gold, as predicted. A return trip never materialized partly due to lack of funding and partly due to the fact that I'd been accepted at the University of New Hampshire to pursue and achieve my Doctorate Degree.
Subjects: Chlorophyll, Gold ores, Fluorescence
Places: Humboldt County, Nevada, Humboldt County (Nev.)
People: Arnold F. Theisen
Time periods: It's about trying to detect the uptake of gold by sagebrush plants through possible changes in the chlorophyll fluorescence of their leaves.
