SELT Survey Results

This is an advanced course that explores the relationships between marine chemistry, marine biological and geochemical processes - with a focus on developing an understanding of the interplay and responses between ocean chemistry, marine biology and global change. Topics covered include the theory and application of chemical and isotopic tracers in oceanography and palaeoceanography, macro- and micro-nutrient cycling, sediment and suspended particulate interactions, element speciation, and biomineralization. Practical work will cover a range of standard and sophisticated laboratory methods for nutrients, elemental, isotopic and chemical speciation analysis, as well as a field sampling excursion to the South Coast of NSW.

Learning Outcomes

Upon successful completion, students will have the knowledge and skills to:

  1. Understand the chemical processes that influence carbon uptake by the ocean
  2. Demonstrate an understanding of the processes involved determining the nutrient structure of the ocean
  3. Undertake chemical analysis of water samples collected in the field setting
  4. Describe the biogeochemical processes that influence compounds and organisms in the ocean in context of recent literature

ANU has educational policies, procedures and guidelines, which are designed to ensure that staff and students are aware of the University’s academic standards, and implement them. Students are expected to have read the Academic Misconduct Rule before the commencement of their course. Other key policies and guidelines include:

Assessment Requirements

The ANU is using Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. For additional information regarding Turnitin please visit the ANU Online website Students may choose not to submit assessment items through Turnitin. In this instance you will be required to submit, alongside the assessment item itself, hard copies of all references included in the assessment item.

Moderation of Assessment

Marks that are allocated during Semester are to be considered provisional until formalised by the College examiners meeting at the end of each Semester. If appropriate, some moderation of marks might be applied prior to final results being released.


Lectures will be recorded while the tutorial and labs/pracs will be face-to-face. The lectures will be recorded for students who cannot attend the lecture and placed on wattle.

The field trip is not compulsory, but students are strongly encouraged to attend to gain hands-on experience in field sampling.


The exam will be in the designated exam period after semester 1.

Please note, that where a date range is used in the Assessment Summary in relation to exams, the due date and return date for mid-semester exams indicate the approximate timeframe in which the exam will be held; the due and return date for the end of semester exams indicate the approximate timeframe in which the exam will be held and the date official end of Semester results are released on ISIS. Students should consult the course wattle site and the ANU final examination timetable to confirm the date, time and venue of the exam.
