This project supports an undergraduate research initiative in Lake and Wetland Studies within the Geology Department. New equipment enhances undergraduate field and laboratory research experiences in two new courses (Coastal and Wetland Geology, Modern Sediments) and several existing courses. The project provides a vibracoring rig, a rapid grain size analysis system (settling tube), a video core logging system, and two water level float recorders. This equipment is being used to introduce focused Lake Champlain Basin research problems into the undergraduate curriculum at all levels. For example, the Modern Sediments course is aimed at advanced undergraduates and should prove to be a springboard to senior research for many of them. This course has the format of a lab seminar course. The course meets once a week for 3 hours. Initial sessions focus on background reading and discussion directed toward the solving of a particular research problem. The remainder of the course is entirely made up of stating the problem and solving it through fieldwork and laboratory analysis with the class working together as a whole. Students collect cores and water-level data, perform grain size analysis, video-log the cores, and describe the Holocene evolution of lakeshore wetlands and the Champlain Basin. The ultimate goal of the course is to produce original scientific research worthy of presentation at a professional meeting. Introductory level courses, such as Oceanography, can benefit as well; the class participates in the taking of a sediment core and some very basic facies analysis to illustrate concepts of environmental change and basic stratigraphy, providing some insight into how scientists have deciphered the evolution of the ocean basins and large lakes such as Lake Champlain.

该项目支持地质系内湖泊和湿地研究的本科生研究计划。新设备增强了本科生在两门新课程（沿海和湿地地质学，现代沉积物）和几门现有课程中的实地和实验室研究经验。该项目提供了一个振动钻孔钻机、一个快速粒度分析系统（沉降管）、一个视频岩心测井系统和两个水位浮子记录仪。该设备被用于将重点关注的尚普兰湖流域研究问题引入各级本科课程。 例如，现代沉积物课程是针对高年级的本科生，应该证明是他们中的许多人的高级研究的跳板。本课程采用实验室研讨课程的形式。该课程每周举行一次，每次3小时。最初的课程集中在背景阅读和讨论，旨在解决一个特定的研究问题。课程的其余部分完全由陈述问题并通过实地考察和实验室分析与全班一起解决问题组成。学生收集岩心和水位数据，进行粒度分析，视频记录岩心，并描述湖岸湿地和尚普兰盆地的全新世演变。该课程的最终目标是产生值得在专业会议上展示的原创科学研究。入门级课程，如海洋学，也可以受益;该类参与采取沉积物核心和一些非常基本的相分析，以说明环境变化和基本地层学的概念，提供一些深入了解科学家如何破译海洋盆地和大型湖泊的演变，如尚普兰湖。
