ScienceDaily: Martian Polygons and Deep-Sea Polygons On Earth
Paper here. Really cool stuff, although I’m not quite sure what to make of it.
Also, here’s some desiccation cracks found on Mars from some research done three years ago. I’ve never really heard about deep-sea sediment patterns like that, so I’m curious — how do these things form? How are they different from, say, plain old mud cracks like the ones in the 2009 study? How would you tell them apart just from using overhead photos? Is it just the size that’s important? I guess the northern hemisphere does make sense for a large ocean of some kind, but still.
Once I’m done this course I think it’s time to hit the geology and planetary science books again, because holy shit am I rusty on this stuff.
