9351733 Retelle A recording CTD, an acoustic sub-bottom profiling system, and a magnetic susceptibility system are being used in the analysis of sedimentary processes and stratigraphy in lacustrine and nearshore marine environments. The addition of this equipment is allowing for development of field and lab exercises in courses in Sedimentology, Glacial, and Quaternary Geology, in two current field courses, and in faculty-student research. The CTD unit is being used to monitor controls on modern sediment transport and deposition such as salinity, temperature, and oxygen in the water column. The acoustic sub- bottom profiler is an "echo-sounding" system that is being used to obtain detailed continuous records of sediment fill in transects across the lake or marine basins. The magnetic susceptibility system is being used to determine the magnetostratigraphy of sediment cores recovered from the lakes and marine basins which will subsequently provide a means for correlation of cores within the basin. The new equipment is greatly strengthening our existing program of environmental and paleoenvironmental studies by introducing students to modern sedimentological and stratigraphical techniques that provide detailed information on sedimentary processes and depositional environments. ***

9351733 RETELLE录制CTD，声学子底分析系统和磁化敏感系统正在用于分析湖泊和近岸海洋环境中的沉积过程和地层。 该设备的增加允许在当前的两个现场课程中以及在教师研究中开发实验室和实验室练习。 CTD单元用于监测水柱中现代沉积物传输和沉积（例如盐度，温度和氧气）的控制。 声学子底剖面是一种“回声”系统，用于获得详细的连续记录沉积物填充湖泊或海洋盆地的样带。 磁化率系统用于确定从湖泊和海洋盆地中回收的沉积物岩心的磁层学，这随后将提供盆地内核心相关的方法。 新设备通过向学生介绍现代的沉积学和地层技术，从而大大加强了我们现有的环境和古环境研究计划，这些技术提供了有关沉积过程和沉积环境的详细信息。 ***
