Pilot 5.6 | EO based phytoplankton biomass for WFD reporting

Pilot 5.6 | EO based phytoplankton biomass for WFD reporting

A good water quality is the base of a healthy ecosystem with rich biodiversity. Aquatic ecosystems also provide essential services for drinking water, irrigation, recreation, aquaculture and fisheries. The EU Water Framework Directive recognizes this and requires member states to monitor and, if necessary, improve water quality. Although the spatial component is key to gain insight in the processes in water, regular sample-based monitoring only provides point data.

The use of earth observation (EO) data for contributing to this purpose was promoted by the H2020 EOMORES and CoastObs white paper 'Satellite-assisted monitoring of water quality to support the implementation of the Water Framework Directive'. To generate further recognition and support for EO based products in the scope of the WFD at political, administrative and management levels, WFD ecological status maps of phytoplankton biomass based on EO data will be provided, thereby adjusting to local water types and WFD threshold differences. WFD ecological status products of phytoplankton biomass will initially be provided for lake Peipsi, Lake Võrtsjärv, and Lake Lauwersmeer, with a potential to roll out the approach to a European coverage.

/ Objectives
  • Provide WFD ecological status products of phytoplankton biomass for management of selected water bodies, based on Chlorophyll-a concentrations derived from EO data
  • Rolling out the approach as a larger-scale service with a potential of a European coverage, thereby adjusting to local water types and WFD threshold differences
  • Generate recognition and support for EO based products in the scope of the WFD at political, administrative and management levels
  • Push towards the recommendations as formulated in the white paper 'Satellite-assisted monitoring of water quality to support the implementation of the Water Framework Directive'

/ Key Datasets
  • Sentinel 2 (A and B) MSI data, optical (VIS + NIR), spectral bands 1-8a, resolution 10-60 m. S2 data is available via several sources, including the Sentinel API hub and Google cloud.
  • Sentinel 3 (A and B) OLCI data, optical (VIS + NIR), spectral bands 1-16, 300 m resolution. S3 data is available via several sources, including CODA and EUMETSAT data center.
  • Validation data (Chlorophyll-a) from public databases (EEA, LIMNADES, GEOSS) and from user data bases
  • Information about the WFD bodies: their exact areas, and the applicable thresholds are public (since these are part of the EU framework), usually available via national systems in national languages.
