My research interests are broad and interdisciplinary and include the responses of species, communities and ecosystems to environmental change in aquatic and terrestrial habitats, interactions across habitat boundaries, and the connection of physical and biological data. My early work at the Prince Edward Islands looked at plankton trophic ecology. My PhD focused on invasive species and climate change impacts on the islands. My findings from this work and my experience in both the marine and terrestrial habitats led me to question the possibility of predicting impacts on a larger ecosystem scale, particularly in a system where land-sea interactions are so important. I explored these questions in a postdoc where I used ecosystem models to investigate marine food web responses to variability in resource subsidies that cross the land-sea habitat boundary and ecosystem effects of latitudinal variability of the sub-Antarctic front. I am also involved in a project that uses these methods in the Southern Benguela. The collection of oceanography data is often hampered by various limitations. Marine mammals are therefore an excellent platform to collect data, particularly in regions where other profilers such as Argo floats cannot go. My current work utilizes the CTD data collected by elephant seals to assess the spatial and temporal comparability of seal-CTD and Argo float data. The project will analyse properties obtained with seal data such as mixed layer depth, and the position and structure of fronts, and compare this with other datasets such as Argo.
