This is a picture of a wave crashing on the New Jersey shore. It glows because of dinoflagellates — little, single-celled plants, animals, and bacteria that float around on the water, moving about with the help of long, moveable protein strands called flagella. Some dinoflagellates are bioluminescent; that is, chemical reactions inside their bodies produce light. The result is glowing oceans. Or, as maker Caleb Kraft recently discovered, the dinoflagellates also make for a soft blue nightlight with really nifty special effects.

You can watch Kraft's nightlight project at YouTube. It's pretty simple to do at home. At it's most basic, all you need to do is purchase some bioluminescent dinoflagellates online, keep them alive in your home, and give them a good shaking occasionally to trigger the chemical reaction.

Here's an incredibly cool video showing the prow of a massive ice breaking ship as it plows through Antarctica's Ross Sea. The footage is sped up, to pack two months of travel into five minutes. But, unlike a lot of time-lapse videos, this one also has a really informative audio track, in which marine scientist Cassandra Brooks waxes poetic about the many different kinds of ice and explains why she and her team were out there, breaking through the stuff, to begin with.

Bonus: At the end, you get to see the absolute adorableness that is penguins on high-speed fast forward.

Beachgoers in Qingdao, Shandong province, China, were met with a fuzzy, green blanket of ocean last week, as the water there exploded with algae.

You've heard before about dead zones. These are patches of coastal ocean where river runoff full of fertilizer chemicals have produced massive algae blooms. As the algae die, their decomposition reduces the oxygen level of the water to the point that many fish and other aquatic life can no longer live there.

This is what a dead zone looks like, just before the death.

It's worth noting, when I pulled this photo out of the Reuters files, I could see similar shots, taken on the same beach, in 2010, 2009, and 2008. This isn't a fluke. It's an endemic problem.
