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
Introduction • Wealth of data available • Access vs Accessibility to data • Attracting people to use your data • Produce further research
Topics of Discussion • The CPR Survey • CPR data • Data Storage and Access • Products • Data usage • Further Developments
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
CPR sampling 1946-2003 Over 5 million miles sampled Phytoplankton Colour Phytoplankton zooplankton
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
Environmental data • Almost 1/2 CPR routes instrumented • Temperature, Salinty, Chlorophll • Average temperature per sample
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
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
Data Storage and Access • History • Policy • Access via web and OBIS
Data Policy • Compliant with GOOS • Free access to Monthly and Annual Mean data • Visit Plymouth, UK to access raw data
Standard Areas PCI and Calanus finmarchicus Ocean Biogeographic Information System (OBIS) Web Access & OBIS
Products • SAHFOS WinCPR • CPR Atlas
SAHFOS WinCPR v1.0 • Monthly sample distribution maps for 1948 & 1997
SAHFOS WinCPR v1.0 • Diatom, (Chaetoceros) monthly distribution during 1997

Further developments • Redesigning the database • Further developments of WinCPR • Web Access • Environmental data
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
The CPR database • Further auxillary information • Height of tow point • Length of wire • Microscope number • Location of Sample
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
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
Environmental data • Sea Surface Temperature • Cloud Cover • Wind Speed • Salinity
Conclusions • Data on demand is desirable • Tools to provide easy accessibility • Data available to a wider audience
Finally • Improved data storage • Efficient access • Increased use • Further research • Financial stabilty • Continuation of the survey
