Alaskan Blob Is an Algae Bloom 130

Posted by timothy from the no-sixes-here-just-a-couple-of-nines dept.
Bryan Gividen writes "Time.com is running a story on the previously unidentified blob floating off of the coast of Alaska. The article states that the blob is an algae bloom — far less sinister (or exciting) than any The Thing or The Blob comparison that was jokingly made. From the article: '"It's sort of like a swimming pool that hasn't been cleaned in a while." The blob, Konar said, is a microalgae made up of 'billions and billions of individuals.'"

            It's true, and a side benefit is we get a layer of water saturated with toxic hydrogen sulfide. Millions of years later, all of that sequestered carbon may be returned to us in the form of coal or oil.

          That's an excellent point - and I was going to visit this idea until I read your post. It would be very interesting to see a study on the local ecosystem, and if there are any issues with nutrient runoff nearby from local human population, logging, or agriculture (the usual suspects for nutrient loading and algal blooms). I found it dubious that a quote in the article seemed to indirectly point to global climate change as a cause (the quote was "...as a result of global change"). Seems like it's so easy to scapegoat that as the villain responsible for any malignant ecological change without the need for any, you know, real science. (It's also easier to get grants when a hypothesis or grant proposal's title suggests an agenda-based search for a causal link between phenomena X and global climate change)

          The phenomena that most commonly leads to algal blooms, anoxic water columns, and ultimately a dead zone (or fish kill) is known as eutrophication [wikipedia.org]. I spent my first years of undergrad (literally) knee deep in poo studying nutrient loading in water tables...ultimately leading to eutrophication. What a great wake-up call for me to get the hell out of the natural sciences. Poo stinks almost as much as academic bureaucracy and begging for grants! :)

      Wikipedia points out:

      From Cosmos and his frequent appearances on The Tonight Show, Sagan became associated with the catch phrase "billions and billions". As Sagan himself stated, he never actually used the phrase in the Cosmos series.[18] The closest that he ever came was in the book Cosmos, where he talked of "billions upon billions":[19]

      A galaxy is composed of gas and dust and stars -- billions upon billions of stars.

      -- Carl Sagan, Cosmos, chapter 1, page 3[20]

      However, his frequent use of the word billions, and distinctive delivery emphasizing the "b" (which he did intentionally, in place of more cumbersome alternatives such as "billions with a 'b'", in order to distinguish the word from "millions" in viewers' minds[18]), made him a favorite target of comic performers including Johnny Carson, Gary Kroeger, Mike Myers,[21] Bronson Pinchot, Harry Shearer, and others. Frank Zappa satirized the line in the song Be In My Video, noting as well 'atomic light.' Sagan took this all in good humor, and his final book was entitled Billions and Billions which opened with a tongue-in-cheek discussion of this catch phrase, observing that Carson himself was an amateur astronomer and that Carson's comic caricature often included real science.[18]

      I read an interview with him once where he was asked about it, and he responded that it makes him kind of frustrated, since the phrase is nonsensical. There's no change in order of magnitude, so there's no point in tacking on the extra "and billions."

      • Yeah, well, anyone who's ever watched Cosmos knows that he's said plenty of nonsensical things. It may have made sense to someone baked out of their gourd, but his spiritual commentary was just inane, and his earnest effort to convey his excitement about the universe made the "billions and billions" quote quite plausible. So while it may not have been something he ever said, it certainly captures the essence of (the public image of) Sagan.

    • Ah... I miss Carl Sagan. We really need some more "science celebrities" out there like him to inspire young children everywhere the way Sagan did. Perhaps I am missing out on something or we simply don't have those people any longer.

    algal blooms. One of the prime symptoms of anthropogenic warming is disproportionate warming at night and at the North and South Poles. We're a smart bunch here at Slashdot, right? (Right?) We can figure out what that means.

    Like a previous commenter said, yes, when they die they'll take some of their incorporated carbon down to the sea floor. Along the way, microbes are going to be decomposing it. They use oxygen to do that. If there's enough algae (and this sounds like there is) what that means is that all the fish and everything else that needs oxygen dies in that whole zone. It's like the dead zones in the Gulf of Mexico.

      I think it's a bit much to say these do not happen at the poles. We simply haven't encountered one yet. Algae do live in cold water, the question's just why are there so many all of a sudden? This area of the ocean is pretty rich in marine life normally, though the water is cold. There's a ton of fishing and even a show about crabbing in the general area, and colder waters (especially where they mix with warm water) are incredibly rich in nutrients (though I don't know enough offhand to say this is one of those areas, it.. prroooobbably is, or is close to one).
      Algal blooms in the gulf and off the west coast tend to be caused by runoff from agricultural waters rich in fertilizers. I doubt there's much of that so far north, but there may have been some nutrient-stirring or even -releasing during the recent earthquakes up there? That's a total stab in the dark. I'm not a scientist or even an amateur in this field, but I do know that shaking water can stir stuff up from the bottom.
      though looking at wikipedia.. this has happened before, at least near this area. Down near the bottom there's a picture of a bloom from 1998 in the Bering Sea (the rich sea area I was talkin about) http://en.wikipedia.org/wiki/Algal_bloom [wikipedia.org]

      This might really be more a case of people unfamiliar with a phenomenon blowing it way out of proportion because they don't know that it's happened before. The original article did mention there was concern it was an oil spill, and that quite often there's investigations into strange things in the area that are thought to be oil spills but rarely turn out to actually be so... so at this point I'm thinking this has happened before, if maybe not quite on this scale, but it just wasn't picked up widely by news organizations so you and I never knew about it.

      • I think it's a bit much to say these do not happen at the poles. We simply haven't encountered one yet.

        • That's stretching it a bit. We can explain why people can't fly, and why they can't drink a gallon of arsenic and hydrofluoric acid. I don't believe we could explain why an algal bloom like this couldn't happen. There's still quite a bit about the oceans and marine life that we don't really have a good handle on, so making definite statements like that just doesn't seem prudent.

          Oh, and for the record.. people *can* fly, it just takes some sort of machinery to get it done ;)
