Dr Colin Southwell: BSc (Hons), PhD
Principal Research Scientist: ecology
I have been working with the Australian Antarctic Division since 1994. My primary research interests lie in providing scientific input to sustainable management of populations and ecosystems; the development of cost-effective methods for large-scale monitoring of wildlife populations; and the development of optimal and effective designs for the detection of and attribution of cause to long-term change in the Southern Ocean ecosystem. I currently lead a research program that contributes to the CCAMLR Ecosystem Monitoring Program (CEMP) and to the assessment of seabird status and trends across East Antarctica. I have been a member of the Australian delegation to the CCAMLR Working Group on Ecosystem Monitoring and Management since 2002.
From 1994 to 2000 I led the Australian Antarctic Division’s contribution to the international Antarctic Pack Ice Seals program, which culminated in a circumpolar survey of pack-ice seal distribution and abundance. I was a member of the SCAR Group of Specialists on Seals from 1996 to 2004, and am currently a member of the IUCN Pinniped Specialist Group. Prior to joining the Australian Antarctic Division, I worked with the Federal Environment Department on management of harvested kangaroo species across Australia.
