North Sea Chlorophyll Concentration Maps from MERIS Satellite

Ten-day maps of chlorophyll concentration in the North Sea derived from spectral data. The product was developed by DLR-DFD and the Institute for Coastal Research at GKSS Research Centre Geesthacht as part of the MAPP project. Data was collected by the MERIS instrument on ESA's ENVISAT satellite, with the last recorded update in March 2010.

Use Cases

• Analyze temporal trends in chlorophyll-a concentration across the North Sea using the 10-day composite maps.
• Correlate spectral reflectance values in the 412-900 nm range with in-situ water quality measurements.
• Model phytoplankton biomass distribution from the derived chlorophyll concentration product.
• Monitor coastal water quality changes using the 300-meter spatial resolution geospatial data.

Strengths

• Data provides a 300-meter spatial resolution for detailed regional analysis.
• Spectral data covers the visible-near infrared region (412-900 nm) relevant for water parameter retrieval.

Limitations

• Dataset temporal coverage and update frequency are unclear beyond the last metadata update in 2010.
• Specific sample size (number of images/maps) and geographic bounds within the North Sea are not provided.
