  1. Continuous Plankton Recorder Database: current uses and future directions Darren Stevens & Anthony J. Richardson Sir Alister Hardy Foundation for Ocean Science Email dpst@sahfos.ac.uk

  2. Introduction • Wealth of data available • Access vs Accessibility to data • Attracting people to use your data • Produce further research

  3. Topics of Discussion • The CPR Survey • CPR data • Data Storage and Access • Products • Data usage • Further Developments

  4. The CPR Survey

  5. The CPR collects plankton over large spatial scales • capable of operating at high speeds (>20 knots) • needs a minimum of attention (robust) • designed for ships of opportunity

  6. Some SAHFOS Ships of Opportunity

  7. CPR sampling 1946-2003 Over 5 million miles sampled Phytoplankton Colour Phytoplankton zooplankton

  8. CPR data

  9. Number of records • 196,120 samples analysed • Plankton counted on every other sample • 2,332,114 -positive plankton entries • 450 species • Total plankton entries ~90,000,000

  10. Environmental data • Almost 1/2 CPR routes instrumented • Temperature, Salinty, Chlorophll • Average temperature per sample

  11. Information stored • Extensive auxillary information stored • Route • Name and average speed of ship • Latitude and Longitude of deployment, retrievel and course changes • ID CPR and Internal Mechanism • Impellor angle of the CPR

  12. Information stored • Sample • Latitude and Longitude of the midpoint of the sample • Local time of the midpoint of the sample • Name of the scientist that counted the plankton

  13. Data Storage and Access • History • Policy • Access via web and OBIS

  19. History

  20. Data Policy • Compliant with GOOS • Free access to Monthly and Annual Mean data • Visit Plymouth, UK to access raw data

  21. Data requests & funding

  22. Standard Areas PCI and Calanus finmarchicus Ocean Biogeographic Information System (OBIS) Web Access & OBIS

  23. Products • SAHFOS WinCPR • CPR Atlas

  24. SAHFOS WinCPR v1.0

  25. SAHFOS WinCPR v1.0 • Monthly sample distribution maps for 1948 & 1997

  26. SAHFOS WinCPR v1.0 • Diatom, (Chaetoceros) monthly distribution during 1997

  27. SAHFOS WinCPR v1.0 • Annual abundance of C. finmarchicus in 1958 & 1997

  28. SAHFOS WinCPR v1.0

  29. Calanus helgolandicus (1958 -1999) Maps demostrate change in geographical range Digital CPR Atlas

  30. Metridia lucens (1958 -1999) Maps demostrate diel vertical migration Digital CPR Atlas

  31. Data Usage

  32. Canada France Germany Iceland Italy The Netherlands Norway Portugal Republic of Ireland South Africa Spain Sweden UK USA Who is using the data

  33. Data requests & funding

  34. Publications using CPR data

  35. Further developments • Redesigning the database • Further developments of WinCPR • Web Access • Environmental data

  36. The CPR database • Decrease time taken to release data • Phytoplankton Colour data early release and available for all samples • Improved user-interface • Better information provided for quality control

  37. The CPR database • Further auxillary information • Height of tow point • Length of wire • Microscope number • Location of Sample

  38. SAHFOS WinCPR v2.0 • Extend time series • Include further environmental variables • SST, Cloud Cover, Wind Speed, Salinity • Extend geographical area • Use Lambert co-ordinates • Improved gridding method

  39. Data available via the web • User-defined area for abundance data • Summary statistics • Number of Samples per month • Monthly Mean Phytoplankton Colour Index data • Raw sample data • Metadata on species

  40. Environmental data • Sea Surface Temperature • Cloud Cover • Wind Speed • Salinity

  41. Conclusions • Data on demand is desirable • Tools to provide easy accessibility • Data available to a wider audience

  42. Finally • Improved data storage • Efficient access • Increased use • Further research • Financial stabilty • Continuation of the survey
