The unit demonstrates, from field study, how coastal systems have evolved in Australia over the past 20 000 years as a result of global climatic change, and how human occupation has adapted to such changes, from the evidence left by past sea-level movements on local coasts and estuaries. The unit develops observational, recording and analytical skills about marine environmental change, and associated Aboriginal remains and at the 400 level will require an extended assessment of literature. Assessment is by Literature Review (30%), Field Report (40%) and an interpretive essay (30%).
