Alix Post is a marine geoscientist. She has worked at Geoscience Australia in Canberra since 2002, focussed on understanding marine processes 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. Alix completed a PhD in Southern Ocean palaeoclimates at the University of Tasmania in 2004. Since then she has worked to understand both modern and past environments, and in particular, to understand how environmental factors and seafloor processes influence the critters that live in our oceans. This work helps scientists and marine managers to better understand past climate systems and to protect marine biodiversity.
