Shipmap.org | Visualisation of Global Cargo Ships | By Kiln and UCL
A beautiful visualisation of shipping routes and cargo. Mesmerising!
You can see movements of the global merchant fleet over the course of 2012, overlaid on a bathymetric map. You can also see a few statistics such as a counter for emitted CO2 (in thousand tonnes) and maximum freight carried by represented vessels (varying units).
