Bio-ORACLE: Marine data layers for ecological modelling

Linking biodiversity occurrence data to the physical and biotic environment provides a framework to formulate hypotheses about the ecological processes governing spatial and temporal patterns in biodiversity, which can be useful for marine ecosystem management and conservation.

Bio-ORACLE offers a user-friendly solution to accomplish this task by providing 18 global geophysical, biotic and climate layers at a common spatial resolution (5 arcmin, approximately 9.2 km at the equator) and a uniform landmask.

 

Developed by: 
Bio-ORACLE is developed by a team of marine researchers from the Flanders Marine Institute (VLIZ), the University of Algarve, the University of Melbourne and Ghent University.
