Sample Collection Resources

In addition to digging out Calhoun's experimental catchments and installing new 90-degree V-notch weirs for runoff measurements, one of the catchments will be intensively measured by the installation of throughfall collectors, groundwater wells, recording piezometers, and tensiometer nests. 

In March, 2014, a new weir blade was successfully installed at one of the historic watersheds to be re-instrumented for eco-hydrology experiments.  Photo: Norm Pelak (Duke CEE).

A 52-year old soil sample archive from a land-use change field experiment is available for studies of land-use change effects on the belowground ecosystem.  Samples have been collected and archived about every five years from 16 permanent 0.1-ha plots, from four soil depths.  Nearly all samples are still in the archive.

A collection of black and white aerial photos from the southeast corner of Union County, South Carolina is being digitized.
