  1. SADCO Southern African Data Centre for Oceanography: regional facility for storing and sharing marine environmental data Marten Grundlingh

  2. SADCO: Target Area, data load 2001 Africa SADCO

  3. SADCO: Target Area; all data

  4. SADCO: data administration • ORACLE DBMS, UNIX workstations • Data can be flagged for security • Daily backups for safety • Quality control checks on all incoming data (IODE, WMO customised)

  5. SADCO: data types (1) • Vertical profiles (>200 000 stations): • temperature • salinity • Nutrients, chemistry • Currents • Surface weather observations (6m reports, 45m observations)

  6. SADCO: data types (2) • Time series data: • Currents • Temperature • AWS (land-based or buoy) • Other • Plankton (database may be remobilised for BCLME)

  7. SADCO: products • Web-enabled raw data extraction (standard & customised, off-line) • Extractions by • geographic area, • cruise or • deployment

  8. Means, statistics • Graphs, downloadable

  9. SADCO: inventory • Scout for data (insight into regional data) • Existing public inventory of surveys • sadco.csir.co.za

  10. Examples of data use • Climate changes, rainfall indices • Maritime accidents • Oceanographic research • Environmental impact • assessments • School projects (outreach) • Maritime consultancy

  11. SADCO: communication • Quarterly newsletter • Liaison visits, presentations • Web site • sadco.csir.co.za

  12. SADCO: management model • Stakeholders comprising all southern African marine organisations [MCM, SAN, CSIR, NRF (universities), NMFMR, SAWS, IMT, UCT] • Stakeholders serve on Steering Committee to oversee data centre, and decide policy

  13. SADCO configuration

  14. SADCO infrastructure (CSIR) (on site in Stellenbosch)

  15. SADCO: development 2005 1. OBIS • OBIS node for sub-Sahara • Entrance into biodiversity domain • Same management model (no full-time staff) • Four main data providers (to date) • Other data providers invited afrobis.csir.co.za:8000

  16. 2. Trace metal data • Regenerating chemical database • Load data from CSIR Durban

  17. 3. Regular data loading: • Surface weather data • CTD data (Namibia, MCM, France, Germany) • GODAR data (WDC-Oceanography) • AWS data (MCM) • ADCP (ACEP) • Ship-borne currents (CSIR)

  18. 4. Possible expansions: • Plankton data (BCLME) • Involvement with SAEON • Satellite data of suitable format (BCLME/SAEON) • Production of environmental indices (BCLME) • indices to indicate the status of certain parameters (within a geographical area, depth interval, using algorithms defined by a user community) • Can be computed at given time intervals (e.g. quarterly), or for given cruises, etc.

  19. SADCO: access • Web access to Inventory • Web access to data bases • Downloadable data & products • Off-line requests

  20. Free data access • Open on-line web access to Inventory • Open web access to SADCO data bases only for funding organisations • Off-line access to data • Open access to OBIS

  21. SADCO: Learning points • Core data • Cost efficiency • Consistency • Commitment

  22. SADCO: Summary Existing, functional, web-enabled small data centre Range of services and data Stakeholder representation on Steering Committee Cost-efficiency through collective funding, no full-time staff Invitation to contribute data to OBIS

  23. Thank you
