The Night Shift

Pink Tentacle has some rather icky, but compelling, time-lapse video of a "deep-sea feeding frenzy." Critters die in the deep all the time, right? Ever wonder how the ocean floors stay so clean? Here's your chance to see the cleaning crew in action. My response? "Ewwwww," and, "Cool!"

A Tail For Fuji

I just thought this was neat. Bridgestone (you know, the tire company) used its expertise in working with rubber to make what's thought to be the first-ever artificial fin for a dolphin that had lost her tail fin (and much of her swimming ability) to disease. The dolphin's name is Fuji, and she lives at the Okinawa Churaumi Aquarium. Who'd have ever thought they'd come up with a dolphin prosthesis? The rubber fin has allowed her to regain her swimming chops, and even to do some of that impressive dolphin jumping that makes these aquatic acrobats such a treat to see perform, at aquariums or in the wild.

Added note of silliness: If Fuji's name were Flipper, with that tail fin of rubber, we could call her Flubber. I don't know why that strikes me as funny. Put it down to it being Monday. That's probably the best excuse I'm going to come up with.

The Attack Of The Giant Luminescent Squid

"Captain, what will we do? The giant squid has swallowed the mini-sub, and Jenkins and the Foster girl are trapped inside. We've got to save them." Cartwright clutched his chest and let out an agonized moan as he pled with the captain to find a way to save his lost ward. "How will I ever face her father again?" "Shut up, Cartwright," the captain commanded tersely. "Don't you know what this means? That creature's mother is still out there. If we try to leave this cave we're all doomed." Both men sank into fearful silence as the reality of their situation inexorably overcame all other considerations. There would be no escape from the glowing monster that waited to devour the Sea Queen and all aboard her, drawn by the secret, experimental, bio-nuclear power source that gave her life. Their very strength would be their downfall, and their watery playground would be their grave.

Mmmm, bad sci-fi... I'm a sucker for it. Who can resist the attack of a giant killer squid? Not me. I don't, however, know much about marine biology, outside of various televised misrepresentations from science fiction, and the occasional documentary from the Discovery Channel. I do find the topic interesting, though, and I found this article at NewScientist.com, by Catherine Brahic, and its links to real undersea video (not the Hollywood kind), educational and worth tossing your way. The article tells of the first-ever video of a large deep-sea squid, the Dana octopus squid, and what scientists have learned from the encounter. Brahic says that the squid is bio-luminescent, with "bulbs" at the end of two of its arms, and that, "...the Japanese researchers who caught the squid on camera think they may have seen it attempt to communicate with the small torches they were dangling along with the bait in front of their underwater camera."

There are three short film clips linked from Brahic's article. They all took a while to load, and are dark and under-watery, but the third one in particular was pretty cool. It's a video of the Dana squid attacking the halogen spotlight of the underwater camera used to film it. Turns out that, whereas scientists used to think large deep-sea squid were sluggish and somewhat passive, they are actually quite quick and aggressive. Like I said, marine biology isn't really my thing, but since the giant squid brought back fond memories of really bad old sci-fi flicks, it lured me in. Actual video of a giant squid attacking undersea vessels?!! Neato.

Oh, by the way, the Foster girl and Jenkins saved the day. The girl, who was the only clear-thinking person under the sea that day, suggested reversing the polarity on the armour plating (whatever that means.) Jenkins crawled through the super-heated coolant tubes to manually adjust the predictably frozen controls, and that did the trick, causing the baby giant squid to "reverse course" on the digestive front, and cough up the mini-sub like he'd had too much cotton candy at the squid fair. They passed the news on to our somewhat-less-than-heroic captain, who finally slunk out of the cave with his bio-nuclear-powered tail between his legs. They discovered that Mom was really an alien from the planet Arthritis, and learned how to communicate with her using a disco ball and some rope lights. Turns out she's a big Hugo Chavez fan, which started a whole new series of problems, sure to lead to a sequel. The end.

Going Down

I almost never wish I had lots of money. I've learned enough in my 40-odd years to know that if money is an aim in itself, you will never have enough of it. There will always be reasons why you "need" more than you have now, and who wants to live their whole life with that kind of discontentment? Better to be content with what you've got, if at all possible, don't you think? Having said all that, however, this Popsci.com article, by Michael Behar, did make me wish that I could be rich, just for a week or two, sometime after September 2008. Why September 2008? Because that's when the world's first underwater resort, the Poseidon Mystery Island, is scheduled to open its hatches off a Fijian coral reef.

Bruce Jones, a builder of luxury submarines, is taking his underwater endeavors to a new level. Here's a taste:

Jones designed Poseidon to provide guests—scuba aficionados and landlubbers alike—with an all-inclusive vacation package: fine dining, stunning views of the surrounding lush coral habitat, and the opportunity to dive directly from the hotel’s airlock, a hatch that lets divers out but keeps the sea from flooding into the hotel. Once the resort opens, visitors staying in one of the 550-square-foot guest rooms will enjoy a 270-degree view of the vibrant coral reef and tropical fish, visible through floor-to-ceiling windows and illuminated by external flood lighting. Guests will access the hotel through two elevators. Because the interior pressure will be held at one atmosphere (the same pressure as onshore), they won’t have to worry about getting decompression sickness. A Frisbee-shaped module at one end of the resort will house a kitchen, reception lounge and 3,000-square-foot rotating restaurant and bar. A second saucer will enclose a library, a conference room, a wedding chapel, a spa and the largest underwater accommodation in the world, the 1,200-square-foot “Nautilus” suite priced at $15,000 a night.
My hometown comes in for a bit of the action:
To keep costs down, the entire structure will be assembled in a shipyard in Portland, Oregon, and transported by a heavy-lift ship to Fiji. Meanwhile, engineers will drive guidance pilings into the seafloor. The hotel will float off the ship in one piece, and divers will thread small metal rings, bolted to the hotel’s exterior, onto the pilings. These pilings keep the structure aligned until divers can pin the hotel’s steel legs to the reef. The whole structure is then ballasted until it sinks to the seabed.
Sounds ambitious, but won't it be cool if they can pull it off? I wonder if they'll be giving tours of the hotel before it ships out of that shipyard in Portland? Just getting to see the thing while it's still on land would be a kick, even though it's really the ocean views that will make this hotel so special. Follow the link to the article. There's video that will show you just what a treat hotel guests are in for, once the Poseidon Mystery Island settles into her final home.

One question I had from watching the video was what impact the hotel will have on the marine life nearby. Since I can only imagine the hotel lights and noise will be a new and different experience for its aquatic neighbors, I can't help wondering whether they will cause any problems for the local ecosystem, and clearly, there would be other concerns as well. One assumes there must be adequate systems to deal with such things as waste disposal and energy needs, but the Popsci article didn't go into depth on these issues. I can see why; the piece was really more about enjoying the idea of an underwater adventure, than about janitorial details. As such, it did its job. It certainly made me want to go on holiday "under the sea."

Now, at $15,000 for a week's stay in a 550-square-foot room, I don't expect to get to schedule a visit--ever. I can't help dreaming a little, though, and if ever anything could make me wish I had more money, it would be this--this and maybe a chance to ride a space elevator up to a space hotel. If I had the resources for just one, and both were actually available, it would be a very hard decision to choose between the two. Would it be hard enough to make me wish I wasn't faced with such a choice? Probably not.
