ANNOUNCEMENTS First of all, I put up two energy resources information on bSpace. I wanted to show you how the Obama administration is dealing with energy sources and the issue of energy conservation. I want to tell you that what we are talking about right now is very much in the public eye. The other thing that I wanted to point out is that the next three lectures will all be guest lectures. One will be a woman on campus who handles green buildings. This is directly related to the energy question, which is looking at energy use and the money that goes into energy use. Then we’ll have Chuck Davis from Crossroads, talking about organics and sustainability. The third lecturer will be from San Francisco also, talking about the issue of energy. Last time, I pointed out that we didn’t do anything in this country with nuclear energy. Just recently, Obama authorized two nuclear plants to be built in Georgia. He wants to go back to nuclear as another resource. It is not renewable, but takes away from Carbon Dioxide release. This power point has been posted on bSpace. LECTURE Let us look at the carbon cycle once again. A lot of carbon dioxide goes into the ocean. A lot goes in as organic matter. The remains of marine animals become organic carbon, which become part of the sediment. I also pointed out that the clams, snails and algae all secrete calcium carbonate, which makes marines biota . The cycle begins when carbon dioxide goes into the water directly as gas, some of which goes into the water, and some goes into the shells of the snails, clams…etc. Calcium carbonate is picked up from organic tissues which then becomes dissolved carbon dioxide and falls down to the sediment. The sediment does not get recycled a lot, and if it does, it a very slow process. The ocean is a great tank of holding carbon dioxide
