The information system PANGAEA - Publishing Network for Geoscientific & Environmental Data (http://www.pangaea.de) is aimed at archiving, publishing, and distributing data related to climate variability, the marine environment, and the solid earth. The system is a public 'data library' distributing data to the scientific community through the Internet. Data are stored in a relational database in a consistent format with related meta-information following international standards. Data are georeferenced in space and/or time, individually configured subsets may be extracted. Any type of information, data and documents may be served (profiles, maps, photos, graphics, text and numbers). Operation by AWI and MARUM is assured in the long-term. Both institutes provide the technical infrastructure, system management and support for data management for projects and for individual scientists. Most important collections from Antarctic research archived in PANGAEA so far are the data of the Cape Roberts Project, geological maps and age determinations of rocks, a complete set of JGOFS data including those from the Southern Ocean, any marine sediment cores, documantation and analytical data from German expeditions and an increasing inventory of the published data from the running EPICA project.
