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.
yesterday
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?
December 8
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?
December 8
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…
December 7
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…
December 7
Yep- that's another one we will examine in tonight's session.
December 7
North End peeps will always make the connection to the "Krug Park Lagoon"... which... is obviously a different sort of thing. ;)
December 7
The type of reef we will study in the Keys is a unique type... this will come up in tonight's session!
December 7
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!
December 7
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!

Hmm...I also had heard of the Great Barrier Reef, but I never knew it was a stage of formation. I think I thought it was actually just part of the name...
December 6
I'm afraid I disagree, Carsen. Spongebob is a great educational tool. (Here's the Goo Lagoon for future reference...) I definitely learned that sponges were living creatures. =D But I also didn't know what an atoll was. Or where a lagoon was locate…
December 6
Last weeks discussion was also amazing for me. I learned so much and was totally interested. I definitely agree that bombing Enewetok was a terrible idea! The story about the seashell is crazy! Thank you for sharing it with us. It helped me to under…
December 6
I totally had the wrong idea about lagoons as well! Whenever I hear the word “lagoon” I always think of a nasty creature crawling out of a green swampy area. Haha. I had also never heard of an atoll as well until this class. I had always thought tha…
December 6
First of all, I searched for an animation of the coral formation process and found this site. Not only does it clearly explain the formation, it also reveals a fascinating fact: "The process of atoll formation may take as long as 30,000,000 years to…

Nearly 100 new species described by California Academy of Sciences in 2009

In 2009, researchers at the California Academy of Sciences added 94 new relatives to our family tree. The new species include 65 arthropods, 14 plants, eight fishes, five sea slugs, one coral and one fossil mammal.

Icy moons of Saturn and Jupiter may have conditions needed for life

More insight into radioactive salt marshes

A researcher has analyzed gamma radiation in salt marshes. The development of salt marshes, vegetated areas periodically flooded by the sea, occurs differently than was previously thought. Knowledge of salt marshes is essential for the development of dynamic but safe coastal zone management.
