Indicators - Data
• Data extracted automatically from each of 10 regions daily,
from model/EO (e.g. median, 90th percentile), and sent to
Env. Agency
• Simple parametric model is used to indicate if a bloom is

Conclusions
• Web visualisation and analysis systems extend data usage to
non-specialists
• PML system is being developed in
• EC FP7 OpEc;
• EC FP7 EartH20bserve (global water cycle integrator)
• ESA Ocean Colour Climate Change Initiative
• EC FP7 EarthServer
• By using common standards systems are interoperable ie
they can talk data to each other
