Content

This unit provides an overview of the dynamic processes governing the structure and function of marine ecosystems, with a particular focus on applications from the Indian Ocean. The unit introduces key concepts in physical, chemical, biological and geological ocean systems to explore—
• the geological formation and climate history of the Indian Ocean and its modern environmental characteristics;
• the role of weather and climate variability in driving regional ocean processes;
• the dynamics of ocean circulation and waves within the Indian Ocean;
• the diversity of marine habitats and species across the Indian Ocean, focusing on biodiversity and drivers of distribution and abundance;
• how physical ocean processes shape marine ecosystems along the Indian Ocean rim; and
• the influence on climate change on the physical, chemical and biological oceanography of the Indian Ocean and future projections.

Outcomes

Students are able to (1) demonstrate a knowledge of how the Indian Ocean has formed and its climate history, including the processes that have led to its modern environmental conditions; (2) identify how weather systems and climate cycles drive ocean processes through atmosphere–ocean coupling; (3) demonstrate an awareness of the regional ocean circulation patterns and wave conditions along the Indian Ocean rim, and assess the dominant physical drivers responsible; (4) demonstrate an understanding of the major marine habitats, ecosystems and species in the Indian Ocean, and link oceanic physical and chemical processes to the uniqueness and diversity of marine biota; (5) demonstrate an awareness of the major biogeochemical cycles in the ocean than shape marine ecosystems, and how these vary across the Indian Ocean; and (6) identify how climate change has altered modern ocean conditions across the Indian Ocean and the future projections and impacts.

Assessment

Indicative assessments in this unit are as follows: (1) in-class exercises; (2) two field/laboratory reports; and (3) final project. Further information is available in the unit outline.

For units commencing in May 2022 or later the availability of the supplementary assessment is subject to confirmation.

Student may be offered supplementary assessment in this unit if they meet the eligibility criteria.

Except where supplementary assessment is not available in a unit, it will be offered to students in all units who:

• Are in good academic standing overall;
• Have passed over half the units taken in the teaching period concerned, except where they are only enrolled in two or less units in the period;
• Have submitted all assessment items in the unit;
• Have achieved a mark between 45 and 49 for the unit overall, or the same mark in any failed component item in the unit; and
• No finding of academic misconduct has been made against them in the unit concerned.

Additionally student may apply for supplementary assessment in any unit which is the final unit required for graduation in there course and where they have achieved a mark between 45 and 49 for the unit overall, or the same mark in any failed component item in the unit.
