The search for flight MH370, disappeared on its path from Malaysia to China, has made clear, due to the “false positives” trying to find remains, that the ocean is far from clean. In fact, what we often draw (from land) as an empty space, is a quite dynamic world in which “gyres” concentrate surface pollution. Today’s map, by Cameron Beccario, shows the sea currents with updates every 5 days; gyres are not visible (not at least in an evident manner), but it is an aesthetical treat (while being base on scientific data). The Mediterranean and other inner seas are not rendered. On the same website you can see a map of winds, again a treat. Notice that you can switch between cartographic projections, a nice feature.
