The first four chapters of The Enchanted Braid have led me very interested in the coral reef. I think that it is amazing how things so small and so big live in the habitat. I think that it is really amazing how Osha Gray Davidson, author of The Enchanted Braid, has been to the coral reef in the florida keys. im wondering if we are going to the same spot he did? that would be cool. I also think its cool how in chapter 4, pg 45, he said, "In practice, each of us gnawed away ineffectually at the coral, nipping off tiny bits.... when at last a lobe would snap off and we'd catch it, each of us was amazed.... holding the microcolony (coral reef) was like holding nothing at all in your hand." it is pretty neat how something that is such hard stone is even accounting for the buoyancy of the water. I bet you can't break off parts of the coral reef today.
Anyways, I made an animation of people talking about the coral reef.
Hope you like it :)
Before last class time’s discussion I was totally confused! I wasn’t exactly sure why the island sinks so I assumed it was because of the weight of the coral. I now understand that it is because of the weight of the magma. (the coral is just a contr…
There isn't much that was cleared up for me during last class, because I had taken it the exact way that it was intended from the class before it. However, I learned a few things that basically just clarified what I already knew. The idea that Mr. N…
When we covered Midway in class, the whole atoll idea really set in. Once I made the connection between Midway and atolls, I immediately understood them a lot better. The whole idea that we bombed one is amazing still, but if you think about it, we…
Very true I guess but if nothing else, this proves it. And also, if they did not do this, it could have been just another resort island where people come and go all the time so the coral would have been killed or damaged.
Last Monday's class cleared up how the atolls sank, the coral is not the major cause of their sinking, it is the weight of the magma that comes out of the volcano. I was confused about how the coral weighed this much, but this cleared it up for me.
One thing that really was cleared up for me last class was the fact that reefs don't cause islands to sink. It is caused by the magma moving underneath the surface of the plate. I also thought it was cool that there are more islands to Hawaii than w…
Awesome video. But that music drives me INSANE. I can't take it. :X Were pretty much on the same page. I had know idea the process it took to make an atoll. 300,000,000 years seems like a looooooooong time for something to form. But when you see pic…
Awesome video. I forgot all about that.
;)
And yes... atolls are "rare" in terms of the total surface area of the Earth in which they cover. However, in some areas (the South pacific) they are certainly relatively more common. I too concur- I have…
Well... yes and no. A "barrier reef" certainly IS a stage of reef/atoll formation. However, the Great Barrier Reef in Australia, as well as the Florida Keys/Bahamas are a different sort of "barrier reef" in many ways. You are all doing a good job of…
While there are a lot of good things about the reefs to talk about and analyze in a much greater depth, I will only talk about those in a few short sentences. In truth, most of this stuff we learned about with the reefs themselves, I learned when we…
Every year, large numbers of hatchery-raised young salmonids are released into Swedish rivers and streams to compensate for losses in natural production. Butthese fish generally survive poorly in the wild. Researchers have discovered why: the young fish are too crowded at the hatchery.
Some of the most common minerals in biology, including those in bones and shells, have a mysterious structure: Their crystals are positioned in the same orientation, making them behave as one giant crystal, even though they do not look like a faceted crystal.
Milk drinks that lower blood pressure, meat products that reduce the risk of heart disease, chocolate that calms you down and a new range of foods that can fight obesity can be created from marine animals and plants. Japan already has several product ranges on the shelves and research programs are underway all over the world to create more. And now Ireland is well on the way to becoming a player in this worldwide multi-billion euro industry, according to recently presented research results.
Noelle and Darwinia are two adult female leatherback turtles that nest in Gabon, Western Central Africa. A research team has fitted each turtle with a small satellite tracking device, which enables the scientists to monitor their precise movements and observe where and how deep they dive.
Oceanographers have discovered that seawater sound absorption will drop by up to 70 percent this century, due to rising atmospheric carbon dioxide causing ocean acidification. As a result, underwater sound could travel farther, and this could lead to growing noise levels in the oceans. Increasing transparency of the oceans to low-frequency sounds could also enable marine mammals to communicate over longer distances.
