The Australian Antarctic Data Centre (AADC) was established in response to Australia’s participation in the Antarctic Treaty System - (ATS — http://www.ats.aq). The Centre is committed to the free and open exchange of scientific data and is working collaboratively with international centres, networks and scientists to build a sustainable polar data commons (http://www.polarcommons.org). The AADC team blends scientific domain expertise with skills in computing and information systems to deliver professional data management and analysis services to Antarctic scientists and environmental managers. As Australia’s Antarctic Mapping agency, the AADC also supports the logistical operations of the Australian Antarctic Program. This unique combination of functions and skills places the AADC in an ideal position to provide tailored spatial data management services to Australia’s Antarctic research community. Most AADC services are delivered online using well known, robust software development tools and open source solutions. Data delivery systems, where appropriate, use international standards for data exchange and data discovery.
