Geophysical Field Instrumentation for Undergraduate Teaching

该项目将使用现场地球物理仪器，其目的是为学生提供最先进的现场数据收集，建模和解释的经验，在地球物理，地质学，水文学，环境科学和地理学的本科课程中。地球物理仪器在过去十年中经历了一系列革命性的改进。这一技术进步与基于计算机的数据处理和建模程序的类似进步并驾齐驱，它们共同提供了一个前所未有的机会，以前所未有的复杂性来解决公共和私人关注的广泛科学问题。我们正在围绕所要求的设备设计一个新的、扩展的课程计划。它包括修改现有的本科勘探地球物理、地震学和暑期野外营地课程，并引入地球物理仪器与数字信号处理、现场地球物理和地球物理项目设计三个新课程。这些仪器将是计划的、扩展的课程，将满足地质科学系和环境研究项目不断扩大的需求。我们项目的这些改进的目标是为上述学科的本科生提供机会，使他们能够熟练地应用与他们研究领域相关的非侵入性地下调查方法。现场仪器将包括：一个多通道地震仪加一个小型弹性波发生器，一个全场磁强计，一个便携式频域电磁测深系统和一个探地雷达系统。当俄勒冈大学不使用这些仪器时，我们计划将它们提供给本州其他学校的本科生教学。

This project will utilize field geophysical instruments whose purpose will be to provide students experience with state-of-the-art field data collection, modeling and interpretation in undergraduate courses in geophysics, geology, hydrology, environmental science, and geography. Geophysical instrumentation has undergone a series of revolutionary improvements during the last decade. This technological advance has been paralleled by similar advances in computer-based data processing and modeling programs, and together they provide an unprecedented opportunity to address a wide spectrum of scientific problems of public and private concern with a sophistication not previously accessible. We are designing a new, expanded course program around the requested equipment. It includes modification of existing undergraduate exploration geophysics, seismology and summer field camp courses, and introduction of three new courses in geophysical instruments and digital signal processing, field geophysics, and a geophysics project design course. The planned, extended course offerings, in which these instruments will be essential, will fill the expanding needs of the Geological Sciences Department and the Environmental Studies program The goal of these improvements to our program is to provide undergraduate students in the above disciplines with opportunity to become skilled in application of noninvasive methods of subsurface investigation which pertain to their areas of study. The field instruments will include: a multichannel seismograph plus a small elastic wave generator, a total field magnetometer, a portable frequency-domain electromagnetic depth sounding system, and a ground penetrating radar system. When the instruments are not being used by the University of Oregon, we plan to make them available for undergraduate instruction at other schools within the state.
