If you have a TV set (or computer) capable of displaying HDTV, you have to tune in to PBS this week. They are running a show a few times per day called OCEANS IN GLASS: BEHIND THE SCENES OF THE MONTEREY BAY AQUARIUM. It is awesome. The brightness of the colors, details of the scenes, breadth of interesting subjects across the screen is pretty much unrivaled. Plus, you will not get many chances in your life to see a great white whale in captivity. The variety of creatures sharing the tank with it is staggering. The margine biologists have done a stupendous job with this aquarium. Videographers - or a film crew - have done a magnificent job of capturing it. And PBS brings it to your living room for free!
