Scientists have long speculated that large tsunamis could be linked to the calving of icebergs—where chunks of ice break off of the side of a glacier or ice shelf and float away. The Tohoku earthquake and tsunami that happened in March off the coast of Japan finally gave them much more direct evidence of this phenomenon. Fascinating stuff, and a great reminder of how interconnected the world really is.

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.

Neat post about an experimental plastic substitute made from fish scales over at Brian Lam's ocean-themed blog Scuttlefish. So far art student Erik de Laurens "has made not only goggles, but eye-glass frames, drinking cups, and a wooden table with a fish scale inlay" from fish scales.
