Maria Rivera Araya studied the environmental changes in climate, vegetation and fire in Cape York Peninsula using lagoon sediments during the last 33,000 years. She found five main periods of change in the area surrounding the lagoon. These periods were related to changes in sea level and monsoon activity. This thesis will enable a more detailed understanding of past regional monsoon dynamics and human environment interactions.
