Fluid dynamics of Earth’s ocean, colored by surface temperature.
This is why I love the internet: see these? I NEEDED THESE. I hadn’t yet gone looking for them and they came to me.
I’m sort of half-working on this thing based on the idea of certain (US) lawmakers/pundits getting their way, and there are SO MANY consequences to that — economic, social, geophysical… So I need to know how the ocean currents run (or run at the moment, since temperature changes will cause them to change over time) in order to estimate what kind of oceanic environmental issues might arise.
So, yeah. That this exists is a hundred and fifty kinds of awesome; that it showed up on my dash is another four thousand kinds of awesome.
