Getting Your Feet Wet in Putah Creek

Instructors:
David Osleger and Dawn Sumner, Department of Geology, College of Letters and Science

Description: Our proposed course involves the hands-on environmental monitoring of a human-impacted watercourse, the North Fork of Putah Creek that runs through the Arboretum on campus. Measurements of the water, such as temperature, salinity, water clarity, water depth, oxygenation, flow rate, etc. will be taken weekly to build a web-based time series of parameters that will reveal stream dynamics that vary on a range of time scales. The goal of the course is to immerse freshman in the practice, application and relevance of environmental research. We hope to help them develop their analytical thinking skills as well as nurture an interest in the natural history of the local bioregion. The informal, field-based structure of the proposed seminar will facilitate the collaborative exploration of research with faculty mentors, a graduate student TA for the course, and undergraduate geology majors (the latter two groups will be funded with NSF monies). We hope to avoid the typical ‘top-down’ mode of instruction that characterizes most college classes.

Format: The class will meet for two hours a week, with the majority of the activities taking place along pre-determined sites within the Arboretum. Indoor classes will be held in a reserved room in the Geology/Physics Bldg and in the computer lab in the Geology Department. After the first week or two, teams of students will be asked to assume responsibility for a measurement or suite of measurements at a specific site(s) at regular time intervals. Scheduling will be adjusted to fit within the student’s academic schedule. Responsibilities will be assumed cooperatively with an emphasis on students working together in small groups. The context of each contribution to our understanding of the dynamics of Putah Creek and the need for scientific rigor in taking and reporting measurements will be focal points for monitoring efforts. Grading: The final grade will be determined from the depth and commitment of student involvement as well as student presentations of web-based archives of the time series of the data.

About the Instructors: David Osleger is a Lecturer w/ SOE in the Geology Department, with expertise in stratigraphy and sedimentology applied to ancient climates, oceans, and lakes. His current projects involve the occurrence of extreme hydrologic events in the Lake Tahoe basin over the past few thousand years as well as the identification of episodes of seafloor anoxia in ancient oceans as recorded in mountain belts in Mexico.

Dawn Sumner is an Associate Professor in the Geology Department, with expertise in carbonate stratigraphy and geochemistry applied to ancient ocean chemistry and interactions between microbial communities and their environment. Her research aims to constrain the processes and environmental controls on the early evolution of life, with a focus on both the early history of Earth as well as the possibility of life on Mars.
