Because it's Friday: Visualizing ocean currents
In yesterday's post about the visualization of sailing ship data, some of the commenters (and me, too!) wondered about the routes the ships took; for example, giving the west coast of Africa a wide berth just to round the Cape of Good Hope. This NASA visualization of simulated ocean currents, thought it's for the years 2005-2007, provides some perspective.
It's a shame the video isn't set to music: it's both mesmerizing and relaxing to watch. More details about the simulation (including some very cool animations of surface temperatures, which sadly don't appear to be on YouTube) at the link below.
