Delivery Method: In Person
In the Earth sciences, we deal with a variety of data acquired by geological mapping, geochemical analysis, and geophysical surveys. Although such data may be quite different, they can have certain common characteristics; for example, some types of data are recorded as a function of time or geographic location. Consequently, there are certain standard approaches to representing such data, understanding their significance, and analyzing uncertainties. Students will learn how data can be organized and gain practical experience with some basic techniques that will enable them to develop alogoithms for data analysis. While simple data analysis can sometimes be carried out using Excel spreadsheets, many problems will require the use of advanced programming languages such as Python. Geospatial analysis and 3D modelling of various data sets will involve the use of QGIS and Leapfrog Geo, respectively. Lectures will provide the background to the various methods, with the computer-based lab assignments and term project helping to develop skills in practical programming, field data analysis, and 2D/3D modelling.

ACADEMIC INTEGRITY: YOUR WORK, YOUR SUCCESS
SFU’s Academic Integrity website http://www.sfu.ca/students/academicintegrity.html is filled with information on what is meant by academic dishonesty, where you can find resources to help with your studies and the consequences of cheating. Check out the site for more information and videos that help explain the issues in plain English.
Each student is responsible for his or her conduct as it affects the university community. Academic dishonesty, in whatever form, is ultimately destructive of the values of the university. Furthermore, it is unfair and discouraging to the majority of students who pursue their studies honestly. Scholarly integrity is required of all members of the university. http://www.sfu.ca/policies/gazette/student/s10-01.html
