This is really cool, but is it jumping around for anyone else? I zoom in and pan around to an area of interest, then after a few seconds the view is changed to somewhere radically different for no apparent reason. It also randomly toggles the various overlays when it does this(routes, ports, etc).

Do you have your sound turned down perhaps? When you hit play it kickstarts the introductory Talkie 'tour'. Hit pause to stop it!

Thank you! I assumed play/pause was meant for the animation, and that the button was broken.

Ah, that was it. Thanks.

This is great. Some ships seem to fly over continents just like satellites or airplanes - bogus data in database?

More likely vessels using canals not reporting.

From the info section:

Why do ships sometimes appear to move across land? In some cases this is because there are ships navigating via canals or rivers that aren’t visible on the map. Generally, though, this effect is an artefact of animating a ship between two recorded positions with missing data between, especially when the positions are separated by a narrow strip of land. We may develop the map to remove this effect in the future.

What? Well screw you too! I'm on Chromium 49!

Pretty neat demonstration of WebGL technology, but even with 100mbit fiber here at work the map took a few seconds to load from time to time.

Is there no way to preload & cache this data due to using WebGL or is this just this particular app?

1st of Nov, 2012 - A ship goes up between USA and Russia, seems to dock, then joins up with another boat that seems to have been just hanging around for ages above Siberia, then they head off to Europe.

What's going on there?

Perhaps one ship was stuck in sea ice and the other helped it along? It looks like the extent of the ice ends about the same place those two ships separate over Siberia[1]

Anyone got a dump of this shipping data ? Saw it on enigma.io too and it looks like you have to pay to get it (exactearth.com is their source).

I did a quick search and this result seems interesting http://www.marinetraffic.com/fr/p/ais-historical-data
