The primary goal of SAGE is to actively educate students in all phases of geophysics using modern field equipment and the latest computer processing and interpretation tools. 

SAGE emphasizes the understanding of field methods—from fundamental principles through acquisition, processing, and interpretation—all within the context of basic and applied research problems.

Modern Geophysical Techniques

  • Hands-on field experience with seismic reflection and refraction, gravity and magnetics, electromagnetics (including MT), and electrical resistivity
  • Integrative geophysical methods to solve real geological problems
  • Address geological problems of research and practical interest

Multi-Institutional Expertise

  • Classroom instruction and lectures by academic and industry professionals
  • Computer processing and modeling
  • Data synthesis and report preparation
  • University credit may be earned 

Professional Networking

  • Connect with government and industry representatives
  • Introduce yourself to career opportunities
  • Present at professional conferences
