Alix Post is a marine geoscientist. She completed a PhD within the Institute of Antarctic and Southern Ocean Studies at the University of Tasmania in 2004. She has worked at Geoscience Australia in Canberra since 2002. Her research focusses on understanding marine processes, such as those revealed by seafloor bathymetry, sediment samples and imagery, to investigate how the physical characteristics of the environment influence the distribution and diversity of seafloor ecosystems. She has worked on the continental shelf and within slope canyons from the northern tropics of Australia, through the temperate regions and south to the pole. She has sailed on 10 research voyages, with 3 to the Antarctic margin. Her work contributes to marine protected area planning and helps scientists and marine managers to better understand and protect marine biodiversity.
