Geoscientists face increasingly complex problems in the workplace that require ever more sophisticated tools. With the large number of graduates finding employment in environmental geology, particularly hydrogeology, applied geophysical techniques that focus on these fields are of growing importance. This institution has developed and taught for 6 years a successful Field Geophysics course that emphasizes environmental and hydrological applications. This project augments the standard undergraduate teaching suite of geophysical instruments (seismograph, gravimeter, magnetometer, and DC electrical resistivity) with two electromagnetic sensors that are of emerging importance in environmental studies: a ground-conductivity profiling system and a transient-pulse sounder. These instruments give undergraduates experience with electromagnetic methods in both the frequency and time domains, allow them to investigate a range of relevant environmental problems not previously possible, and provide interpretive techniques that are complementary to those used for other data.

地球科学家在工作场所面临越来越复杂的问题，需要更复杂的工具。随着大量的毕业生在环境地质学，特别是水文地质学中找到工作，专注于这些领域的应用地球物理技术越来越重要。该机构已经开发并教授了6年成功的野外地球物理课程，强调环境和水文应用。该项目增加了标准的本科教学套件的地球物理仪器（地震仪，重力仪，磁力计，直流电阻率）与两个电磁传感器，是新兴的重要性，在环境研究：地面电导率剖面系统和瞬态脉冲测深仪。这些仪器为本科生提供了在频域和时域中使用电磁方法的经验，使他们能够调查一系列以前不可能的相关环境问题，并提供与其他数据互补的解释技术。
