I hope they start imaging at least parts of the ocean, like the great pacific garbage patch and other areas of particular interest for meteorologists and environmentalists.

You can't see the garbage patch from space.

I thought the garbage patch is not visible to the naked eye, mostly made up of microscopic particles, and especially not to a satellite with a 3m resolution?

That's correct, it's something like four particles per cubic meter.

I imagine it should still slightly alter the appearance of the water. Check out "Eulerian Video Magnification" for more.

That work is awesome, but don't they need changes over time in order to achieve the magnification? How would you get changes over time with the plastic pollution in order to view it this way?

Use frames from the same area over a span of time....

What's confusing? There's a picture taken every day.

If you're worried about the time span between the frames, I'm certain that shouldn't matter to the algorithm, it's just more noise and maybe the result takes longer to get..
