Chlorophyll in the Malta Shelf Area

This STREAM service provides daily analysis of mass concentration of chlorophyll-a (CHL) anomalies, including spatial index maps for high chlorophyll occurrence and intensity in the Malta shelf area. User specific requests for data access and visualisation are planned for delivery on the STREAM mobile app. CHL is a core parameter in the Marine Strategy Framework Directive which provides the common framework for the assessment of the state of health of coastal seas to ensure coherence with the set goals of productive, healthy and clean European seas. CHL is considered to be a proxy of phythoplankton biomass and hence for eutrophication. Measuring chlorophyll is an indication of how much primary production is occurring in the sea.
