Examines local and ocean climate systems and the way humans are altering the global climate, the impact that this may have on individual organisms and ecosystems, and the capacity for organisms to acclimatise or adapt to these changes. Specifically examines changes in the oceans carbon cycle, ocean acidification and ocean warming. Examines how marine organisms and communities may be affected by, adapt and acclimatise to ocean acidification and warming. Examines how overharvesting and habitat alteration is causing unprecedented shifts in marine biodiversity and community structure.
Topic 1 The marine CaCO3 cycle and ocean acidification
Topic 2 Biological impacts of ocean acidification
- Effect on invertebrates, early life histories and natural variation
- Fish and behaviour

Topic 3 Laboratory Practical 1: Effect of ocean acidification on growth and feeding by herbivores
Topic 4 Climate weather and warming
- The greenhouse effect
- Major greenhouse gases
- Radiative forcing

Topic 5 Laboratory Practical 2: Effects of ocean acidification and warming on early development of sea urchins
Topic 6 Biological effects of warming
Three universal effects of climate change:
- Effect 1: Shifts in distribution – sea urchins, fish and seaweeds
- Effect 2: Changes in phenology – Warming and metabolic theory – Bergmann's rule – Temperature size rule
- Effect 3: Declining body size – Sea ice retreat
Topic 7 Interactions between warming and acidification
Topic 8 Oxygen minimum zones
Topic 9 Other stressors: Trophic downgrading and shifting baselines
Topic 10 Acclimation and adaptation
Topic 11 Seaweeds, bacteria and warming
Unit Learning Outcomes express learning achievement in terms of what a student should know, understand and be able to do on completion of a unit. These outcomes are aligned with the graduate attributes. The unit learning outcomes and graduate attributes are also the basis of evaluating prior learning.
