Frontiers in Electromagnetic Methods II Posters


Submit an Abstract to this Session


Session ID#: 49513

Session Description:
Smaller, capable instruments and larger, powerful computers, along with improvements to processing, modeling, and inversion software have all contributed to advances in the collection and interpretation of electromagnetic data. Frontiers in electromagnetic methods stretch from the 3D imaging of entire tectonic and magmatic systems, across the search for oil and gas, to the study of small-scale structure relevant to environmental, mining, engineering, and hydrological systems. Results from electromagnetic methods are also being incorporated into multi-disciplinary studies using data from other geophysical and geological methods. This session welcomes contributions from all frontiers.
