EARTHSCI 720 : Environmental Geochemistry

Science

2025 Semester Two (1255) (15 POINTS)

Course Prescription

Provides a broad overview of applications of geochemistry across multiple disciplines. In addition, this course will help determine the suitability of different analytical techniques to different problems while providing practical experience in collecting and evaluating geochemical data. Subject areas are wide-reaching and include, geology, environmental science, biology, archaeology, and forensic sciences. No formal prerequisite but knowledge of introductory chemistry will be assumed.

Course Overview

This paper will provide you with a broad overview of the principles and applications of environmental geochemistry across multiple disciplines.  The topics covered include the diverse uses of geochemistry in understanding Earth’s geochemical reservoirs, conditions on early Earth, geothermal systems, chemical weathering, archeology and forensics, life histories, carbon sequestration/underground hydrogen storage, dendrochemistry, and medical geochemistry (plus additional topics based on student interest). The instructor will deliver introductory material around each week’s topic, however this is a strongly discussion-based course and it is imperative that students read all assigned readings prior to class, attend, and participate in discussions. The laboratory exercises focus on analytical geochemistry, complimenting the topical lectures. In the labs you will develop an understanding of which analytical techniques are best suited for your research, as well as providing you practical experience + theory in collecting and evaluating geochemical results from a wide range of materials.

Key Topics

Weekly topical sessions with geochemical application to: geochemical reservoirs, environmental geochemistry, archaeology, forensics, health, paleoclimate, marine geochemistry

Special Requirements

Laboratory work may require additional hours outside designated lab time. Students may be required to pass health and safety inductions for access to laboratory facilities (General, chemistry).

Tuākana

As part of the University-wide Tuākana community, The School of Environment Tuākana Programme aims to provide a welcoming learning environment for, and enhance the success of, all of our Māori and Pacific students. We are led by the principles of tautoko (support) and whanaungatanga (connection), and hope you find a home here at the School. Students who have identified as Māori and/or Pacific will receive an invitation to our online portal introducing the Programme, the resources we have available, and how you can get involved.

Māori and Pacific students are encouraged to contact Sonia Fonua (s.fonua@auckland.ac.nz) for information about the Tuākana programme.

Workload Expectations

This course is a standard 15 point course with no examination (completely internally assessed).

For this course, you can expect 2 hours of lectures/week, a 2 hour tutorial, 6 hours of reading and thinking about the content and 4 hours of work on assignments per week (for 12 weeks of the course).

Delivery Mode

Campus Experience

Attendance is required at scheduled activities including labs and lectures to complete components of the course.
Lectures will be available as recordings. Other learning activities including labs/tutorials will not be available as recordings.
The course will not include live online events .
The activities for the course are scheduled as a standard weekly timetable.

Learning Resources

Course materials are made available in a learning and collaboration tool called Canvas which also includes reading lists and lecture recordings (where available).

Please remember that the recording of any class on a personal device requires the permission of the instructor.

There is no required textbook. However, students are required to read assigned articles from the literature on various topics within the course every week. There are standard geochemical textbooks that provide an additional source of information. Good reference texts are:
Albarede, F. Geochemistry: An Introduction (2nd Edition) (ISBN: 9780521891486)
Treatise on Geochemistry (Second Edition): Available as an e-book through the library

Health & Safety

Students will be expected to complete relevant health and safety inductions for access to laboratories if required.

Student Feedback

During the course Class Representatives in each class can take feedback to the staff responsible for the course and staff-student consultative committees.

At the end of the course students will be invited to give feedback on the course and teaching through a tool called SET or Qualtrics. The lecturers and course co-ordinators will consider all feedback.

Your feedback helps to improve the course and its delivery for all students.

In 2025, the written assignment will include a creative component to help students better demonstrate their understanding of complex topics.

Academic Integrity

The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting their learning. Where work from other sources is used, it must be properly acknowledged and referenced. This requirement also applies to sources on the internet. A student's assessed work may be reviewed for potential plagiarism or other forms of academic misconduct, using computerised detection mechanisms.

Class Representatives

Class representatives are students tasked with representing student issues to departments, faculties, and the wider university. If you have a complaint about this course, please contact your class rep who will know how to raise it in the right channels. See your departmental noticeboard for contact details for your class reps.
