Attention shall be paid to the definition of an Algal bloom. For some cases it is an anarchic increase of<br />
biological material compared to a climatology (seasonal evolution), for other application it may just be<br />
the sudden increase of chlorophyll concentration (thus covering the seasonal trends) as it is presently<br />
done in the Algal Bloom service line of GSE-Marcoast.<br />
Algal Bloom Monitoring Service - Primary Objective<br />
Algal blooms in European waters, either detected by Geo-Oculus or reported by local authorities, shall<br />
be monitored within the algal bloom monitoring service. The service is aimed to provide detailed<br />
information on position, extend and persistence to the users (cp. chapter 0). The data can be derived<br />
either by dedicated observations or within the required routine scanning of the algal bloom detection<br />
service, if applicable.<br />
