The subterranean aquifer ecosystem of the Edwards aquifer is perhaps the most diverse ground water ecosystem in the world. Increased knowledge about the complex hydrologic processes that control water availability in the Edwards aquifer is imperative for optimal resource management.

A cesium vapor magnetometer, mounted in the stinger of a twin-engine Navajo operated by Spectra Exploration Geoscience, measured variations in the earth's ambient magnetic field to better than 30 parts per million. The survey was completed in April 2001 under a cooperative agreement with the San Antonio Water System.
