Instrumentation to Reorient Instruction in Aquatic Biology

点击翻译按钮获取中文摘要

This project funds the purchase of equipment to support improvements in two upper-level aquatic biology courses: Limnology and Planktonology. These two courses serve the Environmental Studies and Marine Biology degree programs, respectively. The new items of equipment include (1) a videomicroscope system, (2) a light/temperature controlled incubator to culture isolated phytoplankton and for controlled growth of phytoplankton in nutrient enrichment experiments, (3) a shaker for use in the incubator, (4) two automated water samplers to permit water sampling during tidal, diel, and storm event periods, a multiparameter water quality monitor for measuring and logging dissolved oxygen, pH, depth, conductivity, and turbidity, (5) an underwater quantum sensor for measuring and logging light flux and other custom inputs, (6) a spectrophotometer for nutrient analyses, and (7) two laptop computers to interface with primary data gathering instruments and perform data analysis and graphics. This new equipment introduces students to state-of-the-art research equipment and techniques, fosters investigative approaches to scientific problems by students working in small groups, focuses on water quality problems associated with urban stormwater detention ponds (a national concern) and local tidal creeks, and provides experience vital for students entering graduate programs or employment in aquatic biology.
