Carnival of the blue 12

is on an island, thank goodness...far from parts well traveled, in unchartered waters beyond the Sea of Certainty, on the Island of Doubt. This outpost of Scienceblogs.com welcomes all who dare to abandon all dogma.

Stop by for the best of ocean blogging if you can do without dogma.

Ocean plant will save the world with ethanol

Give me sunshine and CO2 and I'll make a highly useful and convenient energy source. Sounds too good to be true? Well it isn't. You can kiss climate change goodbye, thanks to a blue-green algae from the ocean.

Umm...that is if all the kinks can be worked out. But hey, it's a great concept that deserves a chance.

Scientists produced genetically modified cyanobacteria that convert sunlight and CO2 into glucose, sucrose, and cellulose that are readily convertible into ethanol. If development goes well, algal ethanol (Alganol?) can be produced using much less land and far fewer resources than corn-based ethanol production.

Sea otters worse than seals in some very bad behavior

A bad behavior spree by a sea otter that took indecent liberties and actually killed up to 20 young seals a few years back seems more extreme than the much-noted recent example of a a seal that attempted to mate with a penguin.

Somehow, the heinous otter crimes have gone unnoticed. The story is that at least two sea otters sexually assaulted young seals and killed the victims through drowning or shock. Most of the problem was caused by a certain sea otter, dubbed "Morgan," that had been found abandoned as a baby and rehabilitated by people and later relased into the wild. But at least one wild sea otter was seen doing similar bad things. The end of the story? Morgan the very bad otter was captured.

Scientists and commenters have suggested that the recent 40 minute seal attack on the penguin is "the most unusual case of mammal mating behavior yet known" but I don't think so. A serial rape and murder spree by sea otters victimizing young seals seems more unusual.

Sea otters certainly look cuddly, but looks can be deceiving.

Ocean dead zone monster feeds off climate change

Bad news from the deep dark and scary ocean, a new sea monster is rising from the depths and threatening people. Or at least it's threatening our uses of the ocean. It's toxic water with no oxygen, and it's getting worse thanks to global warming.

Low oxygen dead zones are not a new thing, but a new study says that the dead zones are getting bigger and scarier, probably because of global warming.

And there may be real monsters in the story. Massive Humboldt squid (bigger than you!) are lurking in the dead zones since they can tolerate low oxygen (like a real monster!), and devouring unsuspecting fish. Are you scared yet? Ready to give up that gas-guzzler, or at least turn off the engine when you park?

Note that the monster in the picture bears no resemblance to actual ocean life, which is mostly fun and cuddly--okay maybe a little to wet and cold to be cuddly, anyway the picture is just a visual metaphor for the scary ocean hypoxia monster.

Rescued from a remote island

Some stranded people were rescued from a remote Pacific Island. The question is: why would anyone want to leave?

No, it's not Gilligan's Island, it's Palmyra. It's beautiful, pristine, perfect, and why would anyone want to leave?

I suppose it would get old after a while, but I'd love the chance to find out how long I'd have to be there before I got tired of it and wanted to leave. Probably longer than the week this stranded group was there.

How about you? Wanna go to Palmyra? And how long would you want to stay? I'm thinking a couple of months at least, maybe a year.
