Aquatic environments such as lakes, rivers, estuaries and coasts, supply a diversity of ecosystem services that support humanity. They have also been subject to exploitation and degradation at a global scale in response to development pressures. Critical to planning for the sustainable use and management of aquatic environments is an understanding of the physical, chemical and biological processes that govern ecosystem interactions and their ability to support biodiversity. This unit provides students with an understanding of how inland and marine ecosystems function, and develops practical skills associated with field, laboratory and modelling based investigations. Case studies of diverse aquatic system types are explored, and associated issues including contamination, Harmful Algal Blooms, habitat loss and biodiversity loss are explored. Management approaches and technologies to restore and sustainably develop aquatic environments are also covered, including approaches to environmental water delivery, nutrient management and ecosystem restoration. The unit includes a five day field trip.
