Field Testing Locations

The USGS HIF operates several field facilities to perform tests in a natural environment and to conduct comparisons of various instruments. Since hurricane Katrina three facilities have been restored and are operational, the Pearl River at Stennis Space Center, MS, the Wolf River near Landon, MS, and the "Corral" site.

The HIF routinely tests instruments and equipment under controlled conditions on the workbench and in environmental chambers to verify vendor stated specifications. Field tests are performed to also evaluate instrument performance in uncontrolled environmental conditions. Sensor performance in comparison to other instruments and tests for durability, longevity, and fouling are some of the things that are effectively evaluated by placing an instrument in the conditions in which it will be used.
