We interrupt our regularly scheduled link-fest for a brief celebration of how much the geoblogosphere – and our readers – rock.
At the end of Earth Science week, we can only look in awe at the generosity and commitment of our colleagues and readers to funding earth science education through DonorsChoose. As a glance to our sidebar shows, donations to our own giving page have exceeded $800, and have already helped to fund 6 projects, giving students in cash-strapped schools the chance to build quake-proof models, measure water quality, and much more.
In addition to our own challenge, the Ocean & Geobloggers collective also includes:
- Jacquelyn Gill at the The Contemplative Mammoth (DonorsChoose Giving Page).
- Nate at Adventures in Geology (DonorsChoose Giving Page).
- Southern Fried Science (DonorsChoose Giving Page).
- Deep Sea News.(DonorsChoose Giving Page)
- In addition, Erik Klemetti has been racking up donations to help kids learn about volcanoes in their classrooms on his Wired Giving Page
Collectively we’ve raised almost $3000 since Monday. We basically rule the Science Bloggers for Students leaderboard right now, demonstrating – as if it needed proving – how much more awesome we are than any other science. To those who have already donated – thank you so much.
We now return to our regularly scheduled highlighting of things worth reading on the internet this week.

Satellite imagery does appear to show that an algal bloom did form in response, but any effects in terms of CO2 drawdown are far more debatable.
