USGS NRP Tucson: Sediment Impacts from Disturbed and Undisturbed Lands

The Vigil Network

The Vigil Network was created in the early 1960s to address the need for long-term, broad spectrum data collection to facilitate the study of the effects of global climate change. It is a system of small sites and drainage basins where geomorphic, hydrologic, and biological data are periodically collected. Observation periods are intended to be greater than the life span of a single individual, and data are intended to be archived in a readily retrievable format to allow study by future generations of scientists.

Several of the sites' pages are still formatted for a previous version of this web site. We are currently in the process of converting them to the current site format. All data files for these sites can still be downloaded during our "remodeling".

The original data files for sites 79-82 are not currently available for us to digitize. We are attempting to locate these files. If and when we do find them, we will add them to the site inventory.

Questions about the requirements for including a site in the Vigil Network should be addressed to Dr. Waite Osterkamp at wroster@usgs.gov.
