The ADEPD project compiled biological and biogeochemical data from a range of international and national deep sea projects in the information system PANGAEA. Diverse data sets were brought together in an uniform data format and are made available to a wider public. More than one hundred biogeochemical variables and 114,000 published and unpublished data sets were compiled in the last two years in PANGAEA. A new and very simple approach to the data base via the world wide web was implemented. Now for the first time a large deep sea data base is easily accessible for the general public on: http://www.pangaea.de/Projects/ADEPD.
