More Information About Darwin
Through out the book The Enchanted Braid, Osha tells about how three botanist's are connected. Two main men named Alfred Russel Wallace and Charles Darwin, worked together in order to prove Darwins theory of evolution by natural selection. As a christian I don't carre for this theory what so ever, yet as someone who is interested in History and Science I have a little schema towards Darwins and the Scoops monkey trials. Through out the first three chapters Osha talked about how Wallace was investigating a Coral Reef and descrbed the creaturs and inhabitants of the reef, some very clear details such as "As I continued swimming in a line perpendicular to the beach, a juvenile green sea turtle apperaed from the right, spotted me, and veered off gracefully in the opposite direction, looking more lie a brd than the reptile t is (but birds decended from reptile, so the impression was apt.)"
Darwin spent over 5 years out at sea going around the eastern cost or South America where he took smaples and preserved severle types of beetles and rocks and fish. Until July 23, 1834 when he first saw signs of the snow topped volcano named Aconcagua. He spent time going up this volcano into more higher peaks and discovered shells at 1300 ft. This is where Darwin took on the atempt to prove that the world was not a static ball of dirt and rocks, but a ever changing and balanced explosion of force at the center. At last in April of 1836 Darwins ship came to the island of Cocos-Keeling, where he began to study the reefs he so longed for. The reef on the Island of Cocos-Keeling is where Darwin claimed that two additional catigories of reefs came in as Barrier Reefs and Fringing Reefs.
"Darwins primary contributon was to introduce the dea that coral reefs evolved (to use a loded word) over time" Darwin died before he had any chance to prove his theory, so in hopes it would be proven and not ignored he wrote a letter to his trusted friend Alexander Agassiz. Having more technology than Darwin did Alexander was able to more faster and work quicker than Darwin did, although it was not enough. So another man named Harry Ladd the head of the next attempt funded by the USA government pcked up where Alexander left off. From such a simple little letter between friends, Darwin was able to inspier scientest's today inside the United States Government. It was so incredable to learn more about Charles Darwin and his early therory and how he had worked so hard to make somthing be noticed and to set such a strong foot in the base of Science.

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…
This should work.
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…
Breathtaking. I want to go see one!
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…
URRRRRRRGGG. Why is the hyperlink NOT working?
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…
OK, so I get the feeling EVERYONE wants to visit one. So... why don't we just all go there?
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…
Yep- that's another one we will examine in tonight's session.
North End peeps will always make the connection to the "Krug Park Lagoon"... which... is obviously a different sort of thing. ;)
The type of reef we will study in the Keys is a unique type... this will come up in tonight's session!
You just claimed Spongebob to be an educational tool? You have now climbed the ladder of awesomeness (in my mind) to an all-new level!
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…
Absolutely amazing!

Hatchery-raised salmon too crowded
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.Dental delight: Tooth of sea urchin shows formation of biominerals
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.Marine Research Is Key To 'Super Foods' Market
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.Turtles' Christmas journey tracked by scientists
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.Rise in human-made carbon dioxide affects ocean acoustics
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.© 2009 Created by Sean Nash
