Does anyone know if global shipping routes for free download (preferably ESRI shapefile) exist? I would need them for my research only as a background presentation on the world image. They can be rough presentation, I would need something like this: http://www.arcgis.com/home/webmap/viewer.html?layers=12c0789207e64714b9545ad30fca1633&useExisting=1
I have already tried the link of Global Shipping Lane Network from Oak Ridge National Labs (mentioned in this post What are the existing datasets of world maritime routes?), but the link does not function anymore.
