Colgate University is teaching a "hands-on" laboratory in the course in geophysics which focuses on the shallow subsurface environment. Such investigations are becoming more crucial as groundwater shortages and groundwater pollution become more common. The course is a modification of the senior-level geophysics course which is being changed so that the lab focuses on those techniques which are most applicable to the shallow subsurface: gravity, seismology, and earth resistivity. The labs are structured in 3 modules, each dealing with with one of the techniques. The first week of each segment is devoted to measurement techniques and data reduction. The following 2 weeks are devoted to data collection within a segment of the Chenango River Valley, a glacially buried valley containing approximately 500 feet of sand and gravel. The final week of each segment is devoted to modelling the subsurface using two-dimensional techniques and personal computers. Each year, the course will investigate a segment of the valley using all three techniques. Over the years, a larger picture of the valley will be acquired as one group of students merges their results with those of years past. Students are also encouraged to utilize the equipment in senior research projects. The university is matching the award with an equal amount of funds.

科尔盖特大学正在教授一个“动手”实验室， 地球物理学课程，侧重于浅层地下 环境 这种调查变得越来越重要， 地下水短缺和地下水污染变得更加普遍。 该课程是对高级物理课程的修改 现在实验室的重点是这些技术 其最适用于浅层地下：重力， 地震学和地球电阻率。 实验室分为3个部分 模块，每个模块处理一种技术。 第一 每个部分的一周专门用于测量技术和数据 还原 接下来的两周用于收集数据 在Chenango河谷的一部分，一个被冰川掩埋的 山谷包含大约500英尺的沙子和砾石。 的 每个部分的最后一周用于模拟地下 使用二维技术和个人电脑。 每个 一年，课程将调查一段山谷使用所有 三种技术。 多年来，一幅更大的山谷图景 当一组学生将他们的结果与 那些年过去了。 我们亦鼓励学生利用 高级研究项目的设备。 这所大学正在用等量的资金来匹配这个奖项。
