2
Introduction n Wealth of data available n Access vs Accessibility to data n Attracting people to use your data n Produce further research
3
Topics of Discussion n The CPR Survey n CPR data n Data Storage and Access n Products n Data usage n Further Developments
4
The CPR Survey
5
n The CPR collects plankton over large spatial scales n capable of operating at high speeds (>20 knots) n needs a minimum of attention (robust) n designed for ships of opportunity
6
Some SAHFOS Ships of Opportunity
7
CPR sampling 1946-2003 n Over 5 million miles sampled n Phytoplankton Colour n Phytoplankton n zooplankton
8
CPR data
9
Number of records n 196,120 samples analysed n Plankton counted on every other sample n 2,332,114 -positive plankton entries n 450 species n Total plankton entries ~90,000,000
10
Environmental data n Almost 1/2 CPR routes instrumented n Temperature, Salinty, Chlorophll n Average temperature per sample
11
Information stored n Extensive auxillary information stored n Route u Name and average speed of ship u Latitude and Longitude of deployment, retrievel and course changes u ID CPR and Internal Mechanism u Impellor angle of the CPR
12
Information stored n Sample u Latitude and Longitude of the midpoint of the sample u Local time of the midpoint of the sample u Name of the scientist that counted the plankton
13
Data Storage and Access n History n Policy n Access via web and OBIS
14
History
20
Data Policy n Compliant with GOOS n Free access to Monthly and Annual Mean data n Visit Plymouth, UK to access raw data
21
Data requests & funding
22
Web Access & OBIS n Standard Areas PCI and Calanus finmarchicus n Ocean Biogeographic Information System (OBIS)
23
Products n SAHFOS WinCPR n CPR Atlas
24
SAHFOS WinCPR v1.0
25
n Monthly sample distribution maps for 1948 & 1997
26
SAHFOS WinCPR v1.0 n Diatom, (Chaetoceros) monthly distribution during 1997
27
SAHFOS WinCPR v1.0 n Annual abundance of C. finmarchicus in 1958 & 1997
28
SAHFOS WinCPR v1.0
29
Digital CPR Atlas n Calanus helgolandicus (1958 -1999) n Maps demostrate change in geographical range
30
Digital CPR Atlas n Metridia lucens (1958 -1999) n Maps demostrate diel vertical migration
31
Data Usage
32
Who is using the data n Canada n France n Germany n Iceland n Italy n The Netherlands n Norway n Portugal n Republic of Ireland n South Africa n Spain n Sweden n UK n USA
33
Data requests & funding
34
Publications using CPR data
35
Further developments n Redesigning the database n Further developments of WinCPR n Web Access n Environmental data
36
The CPR database n Decrease time taken to release data n Phytoplankton Colour data early release and available for all samples n Improved user-interface n Better information provided for quality control
37
The CPR database n Further auxillary information u Height of tow point u Length of wire u Microscope number u Location of Sample
38
SAHFOS WinCPR v2.0 n Extend time series n Include further environmental variables u SST, Cloud Cover, Wind Speed, Salinity n Extend geographical area n Use Lambert co-ordinates n Improved gridding method
39
Data available via the web n User-defined area for abundance data n Summary statistics u Number of Samples per month u Monthly Mean Phytoplankton Colour Index data n Raw sample data n Metadata on species
40
Environmental data n Sea Surface Temperature n Cloud Cover n Wind Speed n Salinity
41
Conclusions n Data on demand is desirable n Tools to provide easy accessibility n Data available to a wider audience
42
Finally n Improved data storage n Efficient access n Increased use n Further research n Financial stabilty n Continuation of the survey
