Earth Science WWW Resources

I started maintaining lists of Earth Science resources in about 1996, when the Web was fairly young. It's so much easier today to find resources, and a lot harder for a compiler to keep track of them, so I've given up any attempt to provide this kind of coverage. Nevertheless, here are a few things you might not find right away with a search engine.

Petrological blogs

Life in Plane Light: The microscope is my friend
