Biomarkers provide unique fossil signatures of past climate fluctuations in sedimentary archives. This project tests their utility for understanding human-environmental interaction by sampling biomarkers and multiple fossil proxies for agricultural activity from the same sedimentary units. Climate change is seen as a compounding factor influencing social success or collapse on remote islands. By examining islands in the remote Solomon Islands and Cook/Austral Islands, this approach will enhance recognition of initial human colonisation and agricultural land-use, provide direct comparisons of fluctuations in climate and biodiversity at sub-centennial time scales, and test hypotheses relating to social-environmental collapse or recovery.
