This module introduces the underpinning aspects of geophysical and remote sensing techniques used to investigate the Earth's surface and near surface. The techniques covered are illustrated by case studies demonstrating their advantages and limitations, for example, for the investigation of contaminated sites and sites suitable for exploitation (e.g. for minerals or for hydrothermal energy) and for monitoring hazardous regions such as volcanoes. The module delivers a synoptic view of active and passive techniques, seismic, gravity, magnetic, radar and electrical methods for sub-surface characterisation and GPS, radar and laser techniques for surface measurements. The techniques are linked through developing an understanding of measurements in terms of both spatial and temporal coverage and resolution.
Students will develop a range of skills necessary to describe the range of applications of geophysical measurements, and discuss the advantages and disadvantages of different geophysical and remote sensing techniques. Students will gain the practical experience required to assess appropriate measurement strategies for specific environmental problems and identify sources of geophysical measurement error. Additionally, students will be able to relate different geophysical measurements in terms of spatial and temporal coverage and resolution.
