Whew! Tonight's quite a night of TV for ocean lovers!

First, PBS will air Cousteau's final installment of his 6-part Ocean Adventures series. Tonight is the second in the two-part series investigating America's Underwater Treasures. Part I featured a lot of great footage, although some would argue it was a bit light on the science. Hopefully, tonight they'll dig a little deeper.

Meanwhile, Discovery is airing "Sinking of an Aircraft Carrier" tonight, Discussing the sinking of the Mighty O, the show examines the struggles -- inclement weather, flooding, high tempers, and grueling labor conditions -- which threatened the project. It's scheduled for 8pm and midnight, so if you want to watch both, you can!
