Ocean Surface Current Visualization-worldwide

[Bobbywhy]

This visualization shows ocean surface currents around the world during the period from June 2005 through December 2007. The visualization does not include a narration or annotations; the goal was to use ocean flow data to create a simple, visceral experience.

(beware, the downloadable visualization files are HUGE)

Nice thing.

I would love to be able to watch it as in Google Earth, selecting places I am interested in.

Actually I wonder if such a program would be not even smaller than the movie I just downloaded. Most of the displayed information is an extrapolation, so perhaps it is enough to remember a vector for just every whole coordinate (degs, latt & long) - and that can be stored with a reasonable accuracy in just two bytes, so 128 kB per whole map (land included), and I doubt they have data better than one measurement per day. That gives around 47 MB per year - minus 25% for lands, but perhaps more dense grid from better known areas. Still, even at 100 MB per year that's far from several GB.

Wow, this is really fascinating! It's amazing to see the intricate patterns and movements of the ocean currents all around the world. It's almost like watching a living, breathing organism. The lack of narration or annotations actually adds to the experience, allowing the viewer to simply observe and appreciate the beauty and complexity of our planet's oceans. I can imagine this being a great tool for educational purposes, as well as for researchers studying ocean currents. And yes, I definitely noticed the warning about the file sizes – they are massive! But I can see why, as the level of detail and accuracy in this visualization is truly impressive. Thank you for sharing this with us!
