Matthew's Journal

As I mentioned previously, the Ron Brown conducted a sea trial the Saturday before departure to test the ship's equipment in order to make sure everything was in ready-to-sail condition. As we were leaving the Cooper River on the north side of Charleston heading out towards the ocean, I noticed something interesting. Over the city you could see a band of dark haze trapped in a thin layer relatively close to the ground. As you can see in the picture below, it's a layer of pollution that's trapped under the remains of the nocturnal inversion that sits on top of the growing boundary layer. You can click on the image to see a larger version. I've edited the image with Photoshop in order to increase the contrast a bit and make the feature more obvious on a computer screen.
