Ensemble Ecological Niche Models for 2019 of 96 European marine species of particular commercial and conservation interest, based on Ecological Niche Models developed with (i) Artificial Neural Networks, (ii) Maximum Entropy, and (iii) Support Vector Machines at 0.1° Resolution. The data report, for each 0.1° cell, how many models (from 0 to 3) overcome a model-specific decision threshold to assess species presence in the cell. A Biodiversity Index is also provided as the count of the number of species (among the 96) potentially present in each 0.1° cell according to the ensemble models. For each ensemble model, a threshold of at least 2 models agreeing on species presence in the cell was used to indicate species presence.
