Raster showing the photosynthetic active radiation (PAR) reaching the seabed, values in mol.phot.m^-2.d^-1. Derived by multiplying the fraction of surface light reaching the seabed by the amount of light at the sea surface. Layer created for use in the 2019 EUSeaMap, and updated in 2018 in order to cover Iceland and the Barents Sea. Dataset's spatial extent covers European Seas including the Azores and Canary Islands, but excluding the eastern Baltic. Created by the EMODnet Seabed Habitats consortium using data from the European Space Agency MERIS instrument.

Raster showing the average photosynthetic active radiation (PAR) at the sea surface between 2005 and 2009, values in mol.phot.m^-2.d^-1. Created for use in the 2019 EUSeaMap, and updated in 2018 in order to cover Iceland and the Barents Sea. In 2022 the coverage was extended to the Caspian Sea. Dataset's spatial extent covers European Seas including the Azores and Canary Islands, but excluding the eastern Baltic. Created by ACRI-ST under contract to the EMODnet Seabed Habitats consortium using data from the European Space Agency MERIS instrument. From Salquin et al (2013): "Daily mean PAR (in mol┬Àphotons┬Àd-1┬Àm-2) was evaluated using the algorithm developed by Frouin in 1989 and updated in 2011 for MERIS using Level 1 Reduced Resolution [1km]. The daily fields are averaged temporally over the period 2005 to 2009."

Raster showing the average photosynthetic active radiation (PAR) at the sea surface between 2005 and 2009, values in mol.phot.m^-2.d^-1. Data was collected by the MERIS satellite between 2005 and 2009 and this layer was created for use in the 2016 EU SeaMap. Datasets spatial extent covers European Seas including the Azores and Canary Islands.

Raster showing a qualitative assessment of confidence in the photosynthetic active radiation (PAR) reaching the seabed, values in mol.phot.m^-2.d^-1. Values are on a range from 1 (Low confidence) to 3 (High confidence). Layer created for use in the 2019 EUSeaMap, and updated in 2018 in order to cover Iceland and the Barents Sea Datasets spatial extent covers European Seas including the Azores and Canary Islands, but excluding the eastern Baltic. The method used to calculate this layer is described in Section 10.1.2 (part of the Confidence Appendix) of Populus et al (2016). EUSeaMap A European broad-scale seabed habitat map Final Report.
