Stanford’s Microdocs project is a well-presented set of video and pdf resources for learning about sustainability and the coral reef ecosystem. Each video is a few minutes long and accompanied by a short article or links to useful sources.

It’s divided into useful topics and easy to navigate (and looks good, too).

And while we’re on the theme of the oceans (again) there’s a brilliant student activity resource centre at the UCLA’s OceanGlobe centre. Everything you could ever need to study marine science.
