7 PANGAEA our data information system

8 doi:1.1594/pangaea

9 Challenges Long-term operation - hardware, software, backup, network Simple and flexible data model - extensible and adjustable to evolving science Scientific and technical standards - for science and web integration Scalable access - depending on different user needs User driven and controlled - to avoid a technical end in itself

10 PANGAEA / WDC-MARE - organisation Project & data managers + - AWI Computer Center MARUM Univ. Bremen technical & scientific organization Bremen network internet

11 Operating Institutions Center for Marine Environmental Sciences, Bremen Alfred Wegener Institute for Polar and Marine Research Bremerhaven

12 PANGAEA dissemination of data and metadata via portal networks

13 PANGAEA - services & activities current: Data management IODP (European part) Data publication Data infrastructures (networking) HERMES - Editorial Final report environment for data management for preparation of data and metadata of projects - Data - Citable portals, data networking sets - Distribution through 3 libraries - with referenced focus on with marine Digital research Object Identifiers (DOI) CARBOOCEAN EUR-OCEANS - Accompanied by CD/DVD with data and local search engine SPP1144 (Interrigde) SOPRAN (SOLAS) ESONET

14 PANGAEA - Statistics (7/27) Corals Atmosphere Ice unclassified Sediment Water Total number of data sets 541,468 Data items > 1.8 billions

15 WDC-MARE - World Data Center for Marine Environmental Sciences Biogeochemistry, Circulation, and Life of Present and Past Oceans PANGAEA - Publishing Network for Geoscientific and Environmental Data

17 World Data Center System of ICSU established during the International Geophysical Year 1957/58

18 Principles of the World Data Center System operation for the benefit of the scientific community long-term archival freely available Principles data exchange

19 Project STD-DOI Data Publishing Technische Informationsbibliothek Coordination (TIB, Hannover) World Data Center Climate - WDC-Climate (MPI, Hamburg) World Data Center for Marine Environmental Sciences - WDC- MARE(AWI/MARUM, Bremen) World Data Center for Remote Sensing - WDC-RSAT (DLR, Oberpfaffenhofen) GeoForschungszentrum - WDC-TERRA? (GFZ, Potsdam)

20 Scientific Earth Drilling Information Service (S E D I S) MARUM WDC MARE is developing SEDIS Phase I for IODP-MI: central metadata catalogue listing of all IODP, ODP, and DSDP datasets

21 Summary Acceptance of a data system stands or falls with symplicity Data must be accompanied by standard descriptions Data must include in its description a usable citation Data storage must be managed by established centers

22 Long term preservation Lifetime of storage media (years): Hard disk 5 CD / DVD 2 Tape 3 Paper > 1 Papyrus > 1 Stone of Rosette

23 Recommendations We have already well establised data information systems. What we need are more data submitted to the centers. Funding agencies should formulate their data policies with appropiate explanations and regulations and special funding should be provided
