Aims

Rationale: Environmental geophysics describes non-invasive techniques used to determine the physical properties of the shallow sub-surface of the Earth. Environmental near-surface geophysics is widely used in both academic research (e.g. Quaternary science) and within industry (e.g. environmental consultancy) and has a wide application across a range of disciplines (e.g., geography, earth and marine sciences, archeology, engineering).

Aim: This module will provide an overview of environmental geophysics with an emphasis on the principles of surface and shallow sub-surface geophysical data acquisition and interpretation. This will be done by a combination of lectures, computer practicals and a one-day fieldtrip for students to gain first-hand experience. The module aims to:

•       Introduce students to key environmental geophysical techniques and methods.

•       Convey important underlying theory and knowledge relating to these techniques.

•       Provide examples of how they can be applied to address different environmental problems.

•       Provide training and experience of geophysical survey design, geophysical equipment, field methodology and data visualization and interpretation.

Through this module, students will gain relevant techniques to perform independent research, and the knowledge and skills gained will have wider application within industry.

Outline Of Syllabus

The syllabus is strongly focused on teaching practical skills used within environmental geophysics. An emphasis is placed on near-surface geophysical techniques.

The module is split into four parts.

1) Introduction to environmental geophysics, including:

•       Principles of environmental geophysics

•       Different applications and methods (e.g. seismic reflection and refraction, electrical resistivity, ground penetrating radar).

•       Limitations and advantages of different methods

•       Data types and open-source material

This will be taught via a 1 x 2-hour lecture and 1 x 2 hour workshop discussing different methods in environmental geophysics (4 hr contact).

2) Geophysical survey design.

•       Principles of survey design

•       Limitations and advantages

•       Planning a survey using secondary data and GIS

•       Pitching a survey design

This will be taught via 1 x1-hour lecture, 1 x 2-hour computer based practical and a 1x 1-hour design workshop (4 hr contact)

3) Data acquisition in the field.

•       Introduction to using geophysical equipment in the field

•       Data acquisition

•       Reflective exercise on data collection

This is taught through a 1 x 8 hour fieldtrip (8 hours contact) where possible, but a virtual alternative will be provided if required.

4) Post-survey analysis.

•       Data processing

•       Data analysis and interpretation

•       Report

This will be taught via a 1 x 3-hour computer based practical with a 1 x1-hour drop-in session (4 hour contact)

Intended Knowledge Outcomes

By the end of the module students will have:

Knowledge and understanding of the application of environmental geophysics for academic and industrial purposes.

The ability to select and apply an appropriate survey design and critically evaluate the appropriateness of said survey.

Knowledge and confidence to design and implement their own geophysical survey, and to process, visualise and interpret acquired data.

Intended Skill Outcomes

By the end of the module students will have:

The practical skills and programming knowledge to plan a geophysical survey and process and interpret the data collected.

Practical skills in GIS/spatial analytical skills.

The practical skills to use geophysical equipment in the field.

Practical experience of handling and processing geophysical datasets in commercial geophysical software packages.

Teaching Rationale And Relationship

The module will be semi-block taught over 5 weeks and will encompass a range of teaching methods.

Lectures will be used to introduce subject matter and background on the theory, method and application of environmental geophysics.

Computer practicals will provide the students with skills in pre-survey planning and post-survey data visualisation, processing and interpretation. Workshop 1 will allow students to reflect on the different methods and applications in environmental geophysics. Workshop 2 is used for the students to pitch their survey plan and then reflect and adapt this plan to be implemented in the field. The final practical teaches the students how to process the data, which is best taught via the students using the software.

The fieldtrip gives the students first-hand experience of data acquisition, which is essential for critical evaluation of their survey design.

As a whole, the module takes the students from principles, through data collection and survey planning, to data processing, and thus teaches them the full geophysical data collection process. This can then be applied to other scenarios, including dissertations and industry problems. A drop-in session will be available after the final practical for students to discuss any queries relating to the data processing and/or the report. The remainder of the module is dedicated to independent learning and time for writing a report. This report will including a write up of the survey design as well as the results, interpretation and conclusions of the data collected in the field.

Assessment Rationale And Relationship

The oral presentation will develop oral and visual presentation skills and show understanding of the taught material. It will demonstrate that students have the ability to plan a geophysical survey with use of computer applications and will assess the students’ problem-solving and decision-making skills. The presentation and subsequent discussion will improve students’ ability to critically evaluate research design and to justify their method.

The report assesses the ability of students to process, analyse and present a range of primary and secondary field data. The report assesses their ability to relate field results to literature and their development of critical argument. Overall, the field report assesses written communication skills and report writing style.
