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 Survey
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
Some SAHFOS Ships of Opportunity
CPR sampling 1946-2003
Over 5 million miles sampled Phytoplankton Colour Phytoplankton zooplankton
CPR data
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
