Description

CALENDAR DESCRIPTION:

An introduction to geophysics emphasizing seismic, magnetic and gravimetric observations of the Earth. Applied geophysics. Quantitative.

COURSE DETAILS:

Course Outline: REQUIREMENT DESIGNATION: Q
Use of physical measurements in determining the subsurface properties of the Earth. Principles underlying analysis of geophysical data. Basic rock physics. Gravity surveying: basic theory, instrumentation, data reduction, and anomaly interpretation. Magnetic surveying: rock magnetism, Earth’s magnetic field, instrumentation, data reduction, anomaly interpretation. Electrical surveying: (i) resistivity of rocks, electrode arrays and current flow in the ground, resistivity sounding and profiling; (ii) induced polarisation, IP measurement and applications; (iii) self potential methods. Seismic surveying: stress and strain, seismic waves, reflection and refraction of seismic waves, critical refraction, rays and waves. Seismic refraction surveying: seismic sources and detectors, geometry of refracted raypaths for horizontal, dipping and undulating layers, data interpretation.


Course Topics:

  • Introduction to geophysical data: physical properties of rocks , sampling, time vs. frequency
  • Gravity surveying
  • Magnetic surveying
  • Electrical methods: resistivity, induced polarisation and self potential
  • Seismic refraction methods

COURSE-LEVEL EDUCATIONAL GOALS:

Students successfully completing this course will be able to:

  • Demonstrate an understanding of the physical properties related to, and applicability of, geophysical surveys employing gravity, magnetic, electrical, and seismic refraction methods.
  • Demonstrate an understanding how field data are manipulated or processed to produce useful information about the subsurface.

Grading

  • Midterm Exam 20%
  • Laboratory Assignments 30%
  • Final Exam 50%
  • Approximate

NOTES:

The fall offering of EASC 207 is via synchronous remote instruction.

For invigilation of remote exams, students will be required to have their webcams on so they can be monitored during the exam.

The technology requirements for successfully completing your course will include: a computer or tablet, internet access, canvas access, zoom access, and a webcam. For the laboratory assignments, you will need access to Microsoft Excel, graph paper, and a printer.

REQUIREMENTS:

No student will be admitted to this course unless all physics prerequisites have been completed, i.e. PHYS 120, PHYS 121, PHYS 131 or acceptable substitute.

ACADEMIC INTEGRITY: YOUR WORK, YOUR SUCCESS

SFU’s Academic Integrity web site 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

TEACHING AT SFU IN FALL 2021

Teaching at SFU in fall 2021 will involve primarily in-person instruction, with approximately 70 to 80 per cent of classes in person/on campus, with safety plans in place.  Whether your course will be in-person or through remote methods will be clearly identified in the schedule of classes.  You will also know at enrollment whether remote course components will be “live” (synchronous) or at your own pace (asynchronous).

Enrolling in a course acknowledges that you are able to attend in whatever format is required.  You should not enroll in a course that is in-person if you are not able to return to campus, and should be aware that remote study may entail different modes of learning, interaction with your instructor, and ways of getting feedback on your work than may be the case for in-person classes.

Students with hidden or visible disabilities who may need class or exam accommodations, including in the context of remote learning, are advised to register with the SFU Centre for Accessible Learning (caladmin@sfu.ca or 778-782-3112) as early as possible in order to prepare for the fall 2021 term.
