OUC/UTas-3A Southern Ocean Marine Geoscience-2019 Autumn
Course Introduction:
Provides a broad understanding of the evolution of ocean basins and margins, their structure and stratigraphy, and their influence on oceanic environments and circulation patterns, with particular emphasis on Antarctica, the other rifted margins of Gondwana, and the intervening ocean basins. Marine geoscience integrates the disciplines of geology, geophysics, and geochemistry, and this course will focus on providing a understanding of: plate tectonics, ocean basin and margin formation, Large Igneous Province formation, oceanic anoxic events, tectonic gateways, and seafloor morphology, with a particular focus on the influence of marine geoscience, e.g., plate tectonics, bathymetry, volcanism, on oceanography.
This course will comprise a series of lectures and tutorials. Lectures will introduce key concepts followed by tutorials to further explore conceptual material and critical concepts.
Course Assessment:
Exam (50%), quizzes and class attendance (25%), tutorials (25%).
