EARTHSCI 732 : Reconstructing Environmental Change


2021 Semester Two (1215) (15 POINTS)

Course Prescription

Examines key issues in environmental change with an emphasis on the South West Pacific during the Quaternary. Methods applied to reconstruct and constrain the timing of environmental change are explored, including glacial geomorphology, environmental isotopes, micro- and macro-fossil remains such as pollen, diatoms and wood, and relevant geochronologic techniques. No formal prerequisite, but an understanding equivalent to EARTHSCI 307, GEOG 334 or GEOLOGY 303 will be assumed.

Course Overview

A detailed knowledge and understanding of the nature and rate of environmental changes during the Quaternary is not only intrinsically interesting but also provides our only real guide to what might befall us in the future. To rephrase the Principal of Uniformitarianism: "the past is the key to the future." Environmental changes interpreted from the geological, geomorphological and biological records are characterised not so much by slow, gradual change, but rather, by extreme, rapid and often short-lived events, especially during the Quaternary (the last 2.6 Myrs of Earth history).

This course explores aspects of the nature and drivers of Quaternary terrestrial records of environmental change, with a focus on the Southwest Pacific region. The objectives are to:

  •     Review of our present understanding of Quaternary paleoclimates and paleoenvironments in the context of theory, field evidence and research methods.
  •     Explain the collection, analysis and interpretation of physical and paleoenvironmental data ranging from terrestrial and lake sediments (and their components) through to tree rings.
  •     Introduce dating techniques used to establish the timing and drivers of major climatic events identified.
  •     Introduce equipment and measurement procedures used to collect and analyse the materials used for reconstructing past environmental change.

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.

Digital 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.

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 against online source material using computerised detection mechanisms.

You may copy the course content for the purposes of private study or research, but you may not upload onto any third party site, make a further copy or sell, alter or further reproduce or distribute any part of the course content to another person.

Inclusive Learning

All students are asked to discuss any impairment related requirements privately, face to face and/or in written form with the course coordinator, lecturer or tutor.

Student Disability Services also provides support for students with a wide range of impairments, both visible and invisible, to succeed and excel at the University. For more information and contact details, please visit the Student Disability Services’ website

Special Circumstances

If your ability to complete assessed coursework is affected by illness or other personal circumstances outside of your control, contact a member of teaching staff as soon as possible before the assessment is due.

If your personal circumstances significantly affect your performance, or preparation, for an exam or eligible written test, refer to the University’s aegrotat or compassionate consideration page

This should be done as soon as possible and no later than seven days after the affected test or exam date.

Learning Continuity

In the event of an unexpected disruption we undertake to maintain the continuity and standard of teaching and learning in all your courses throughout the year. If there are unexpected disruptions the University has contingency plans to ensure that access to your course continues and your assessment is fair, and not compromised. Some adjustments may need to be made in emergencies. You will be kept fully informed by your course co-ordinator, and if disruption occurs you should refer to the University Website for information about how to proceed.

Level 1: Delivered normally as specified in delivery mode
Level 2: You will not be required to attend in person. All teaching and assessment will have a remote option.
Level 3 / 4: All teaching activities and assessments are delivered remotely

Student Charter and Responsibilities
