Geochemical data are complex, and becoming more so as analytical techniques advance. This complexity gives rise to many data management issues that have no simple solutions. The Geological Survey of Canada (GSC) has a long history of collecting and managing geochemical data. The challenges of managing the data are continuously evolving. The emergence of the WWW is causing a revolution in how scientific data are delivered. This paper documents how one group within the GSC is responding to this rapidly changing environment.
