Landscape evolution of the south east Queensland dune fields
Chronosequences have been utilized in many of the earth science disciplines including pedology, ecology, and geomorphology to investigate how a particular variable is a function of time. An ideal location needs to be established where a time-for-space substitution can be demonstrated. Topography has been established as one of the most problematic, due to the widely accepted assumption of topographic (or geomorphic) steady-state. Topographic steady state implies that soil thickness and production are constant; however, steady state is unlikely because landscapes typically are not able to adjust to changes in climate and/or tectonics. Furthermore, a direct measurement of a topographic steady state has not been recorded or presented in the natural world. For the first time we measure a natural system moving towards a steady state and recognise its systematic changes related to reducing variability of hillslope curvature, reported here as surface roughness.
This study aims to enhance our understanding of soil movement within soil-mantled landscapes via diffuse processes. Specifically, how deep does the mobile soil extend when it is not confined by bedrock, and is soil movement slope or depth dependent? Once evaluated, we will assess the applicability of mathematical and laboratory based models that have been the foundation of the landscape evolution literature within the south eastern Queensland dune fields. Lastly, the study will determine the mechanisms driving the evolution of the dune field and provide a quantitative case study of the erosion cycle that was first touched on by Davis 1899 and expanded into more modern processes and scenarios.
I am a watershed scientist who is interested in the complex interaction between biotic and abiotic processes that drive landscape, climate, and ecosystem evolution. Currently, I am a Ph.D. candidate at the University of Canterbury working closely with the Utah State University Luminescence Lab, British Geological Survey (BGS) and Australia's Nuclear Science and Technology Organisation (ANSTO) on a suite of projects dealing with landscape evolution, stable isotope, climate, and modelling. In the past, I have worked with research groups such as the Critical Zone Observatories (CZO), Center for Ecological Research and Education (CERE), Center of Archaeological Materials and Applied Spectroscopy (CAMAS), and United States Department of Agriculture (USDA) on multifaceted projects. Working with such diverse groups, my work tends to be at the interface of many scientific disciplines which has motivated me to become a strong voice for the scientific community and an advocate of science communication.
