This project involves the design, implementation, data collection, analysis and report writing for gravity and magnetic survey conducted over a two month period during the course.
Undergraduate course in applied geophysics
Designed for a geophysics course
Skills and concepts that students must have mastered
Understanding about the workings of spreadsheets
A basic understanding of structure and stratigraphy is extremely helpful for interpretation
How the activity is situated in the course
This is a stand-alone exercise which require the students to work in teams of 3 for a two month period beginning about 4 weeks into the semester. It requires a lot of out-of-class/lab time on their part.
Content/concepts goals for this activity
Conducting a complete project from design through data collection/processing and interpretation to final report writing.
Higher order thinking skills goals for this activity
The analysis and interpretation requires them to relate geophysical data to known geology and structure and to attempt to extend the geological/structural interpretation below the surface
Other skills goals for this activity
Working as a team
Professional report writing
critical evaluation of data quality
Description of the activity/assignment
The purpose of this gravity/magnetic mapping project is to have the students conduct a research/consulting project from start to finish. They are expected to design the project (submit a proposal), implement (collect data) the proposal, process the data, analyze and interpret the results and report their findings. Working in teams, they have to budget their time, assign tasks and get the job done on time. The process is as important as the science, however they have make quality assessments of the data they have collected and justify their interpretation of the data using accepted scientific/geologic principles.
Uses geophysics to solve problems in other fields
Determining whether students have met the goals
I have included as the instructor's Notes an EXCEL check sheet that I use for evaluating each project. In addition, in some years it is necessary to have the students do a confidential contribution evaluation of each other.
