 This webinar is about the international geosample number IGSN and it will discuss how it is used, its structure, its governance model and the underlying technology. The international geosample number is a global network of 19 members on four continents and this webinar will also show in more detail the Australian implementation at CSIRO, at Geoscience Australia and at Curtin University, and give you an outlook into where things will move next. The presentation on the IGSN will then be followed by a short report on the Cutting Edge Science Symposium, Lincoln Environmental Data and Samples, which happened at the end of May, beginning of June in Canberra.
