Kathryn completed her undergraduate degree at Southern Cross University and in her Honours year she researched the fine-scale distribution of humpback whales on their southern migration past Cape Byron, for which she was awarded the University Medal. She was successful in obtaining an APA scholarship to undertake a PhD project to assess the ecological risks to marine biota of hydrocarbon contaminants associated with the use of fuels in Antarctic waters.
This project is funded by an Australian Antarctic Science grant to address the lack of ecotoxicological data needed to assess the impacts of hydrocarbon contaminants in seawater on Antarctic marine species. Kathryn has participated in three research expeditions to the Antarctic continent where she conducted a range of experiments to investigate the toxicity of hydrocarbons from fuels commonly used in Antarctica. These fuels include marine diesels and intermediate fuel oils that are carried in large quantities in Antarctic waters and the experiments aimed to determine the behaviour and bioavailability of fuel hydrocarbons mixed in cold seawater and assess their toxicity to early life stages of a range of Antarctic marine invertebrates. Early life stages are often the most sensitive to pollution, and effects from contamination can decrease reproductive success and impair recruitment of larvae and juveniles, leading to ecologically significant population level impacts. The results from this research will provide the first detailed information on the effects of fuel pollutants on the reproductive success and survival of a range of Antarctic marine invertebrates, and these data provide key information needed for risk assessment models to predict the potential hazards associated with the use of fuels in Antarctica.
