WOW! Red ICE who knew. I can't believe someone actually studied the ice in antartica!
This article was very interesting. It says that the microbes there exist as "extremophiles". I look that up in the dictionary, and it said it was being able to live in extreme conditions. What is the difference between that and thermophiles, because in class we agreed that thermophile meant liking to be in extreme temperatures--not only very hot. Isn't that sort of the same thing as what they are saying extremophiles are? Does extremophile mean it has to be able to live in an area with chemical concentration?
That was a cool article! I didn't know just one place could have so much iron! It's awesome that those microbes can survive in the harshest of conditions. I would love to be a microbe, I could survive with food, oxygen, and water! The author made this article very believable, if it was fake. I wonder if the scientists will further research this topic.
Wow! That is really cool! I wonder how it could be an anoxic environment if a glacier came over it, an oxygen atom could've broke loose. I know it's not very likely, but it's still possible. I think that this article was interesting, and that the author did a good job of explaining the topic, however, I would've liked to see more information. I wonder how the iron forms red rust, maybe because the oxygen latches on to it and some chemical change occurs...interesting!
This article was pretty interesting. I thought that it was cool that something like that could actually exist, and that scientists go. I agree with what josh said, but since it is so interesting, of course scientists will go to research.
I think that this article was interesting, but also, I think there could have been more information on the extremofiles.
I think that the author was very informative about the subject. I never new that ice could become red! Who would have ever thought that ice could turn red, besides scientists. I also think that it is interesting that this finding could help us find a new home once Earth no longer suits us. Maybe if we find a planet that's rich in iron or sulfur, we could somehow turn that into oxygen. Hmmm...
Declan, to answer your question, remember that iron turns itself into rust when in contact with water for a long time. Obviously, some of it melted and it formed the rust.
It's crazy how something can survive in ANTARCTICA, on iron and chemical salts!!! CRAZY!! Also, how did the scientists find the place in the first place? By satellite?
I really liked this article. Maya, I think I may have the answer to your question. Check out these definitions.
Extremophiles: A microorganism that lives in extreme tempetures.
Thermophiles: A bacteria that grows best in high tempatures.
I don't know if that helps, but i think extremophiles live in all conditions, rather then just hot.
I do think that it is cool that there is probably a salt like with no oxygen giving the glacier it's red color. I wonder how they came to that conclusion?
I was reading an article that said that,
"Archaea are known as the extreme halophiles. Halophile means "salt loving." Members of this... group live in areas with high salt concentrations, such as the Dead Sea or the Great Salt Lake in Utah."
I just found this kind of interesting because it reminded me of what we were talking about in class. I was also thinking that these archaea are extremophiles. Just a quick example of extremophiles.
i was thinking and I wonder where all of the iron came from. Maybe there is a pipe that leads from the core to the spot on Antarctica in which the iron comes from
Maya, thermophiles are specific type of extremophiles. Other extremophiles inlcude the halophiles and methanogens...does that help?
Arjun, sometimes microbes can survive without oxygen!! Remember, they're called anaerobic. We will learn about them in class soon.
Excellent explanations Danielle!! Great job clarifying!
