May each of you have the heart to conceive, the understanding to direct, and the hand to execute works that will leave the world a little better for your having been here. -- Ronald Reagan

The Ocean



The ocean is my favorite place; even beats out the woodsy mountains. I'm thinking this because I've just spent some time there. Seven tenths of the earth's surface is water. Arthur C. Clarke commented that it's inappropriate to call this planet Earth, when it's clearly Ocean. The earth weighs 5,940,000,000,000,000,000,000 metric tons. Ninety-seven percent of it is salt water, three percent fresh. We're taught too that water isn't blue, but clear or transparent. It turns out that it's blue. Very pale blue, but blue. If you put pure water in a deep white pool, and looked down into it, it would be blue. If you've ever looked at thick ice of a frozen waterfall, it's blue. Impurities in water is what is doing the reflecting, so the ocean appears gray, turquoise, green and all kinds of variations.
