Abstract
In early 2009 a complex airborne geophysical survey, comprising magnetic, electromagnetic and gamma ray measurements, was conducted to investigate the shallow geological structure at the Island of Socorro, Mexico, in order to derive indications on possible groundwater resources. For the airborne survey was complemented by ground geoelectrical measurements to further detail the airborne results at selected profiles. A total area of 200 square kilometers was covered in early 2009 by complex airborne measurements using an average line spacing of 100 m. Since on-site pre-processing of the electromagnetic data already showed clear indication on groundwater-relevant structures, the layout of the geoelectric profiles could be optimized according to these findings. As a result advanced knowledge on the shallow subsurface structure of the island could be derived. This outcome allowed setting up a research plan for further groundwater exploration measures of the island. However, apart from search for groundwater, the data provides a valuable data base to be interpreted within further investigation in the area of volcanic research and natural protection.
