New Data Products: Phytoplankton Spatio-temporal probability of occurrence

The Presence/Absence maps of phytoplankton in the Greater North Sea https://www.emodnet-biology.eu/data-catalog?module=dataset&dasid=6587  was created by Willem Stolte and Luuk van der Heijden (Deltares). It estimates absences from presence-only  occurrence data available at EMODnet-Biology. This was done by looking carefully at the sampling methods. The product is provided as a refined dataset with a presence/absence flag and as raster maps with gridded probability of occurrences.

The product was the basis for further analysis: Using DIVAnd software and a Neural Network as interpolation methods, a second product was created by Alexander Barth and Charles Troupin (University of Liege): Probability maps for different phytoplankton species in the North Sea https://www.emodnet-biology.eu/data-catalog?module=dataset&dasid=6588
