For those of you in the UK, you might be interested in what looks like a very interesting program. It's called Pacific Abyss and it looks like a sequel to Amazon abyss which was on a few years ago. Basically, they will be diving in the Pacific and hope to find new species of fish. They will be using specialized equipment so they can dive to Depths that not many people have gone to before. They will also be diving the very shallow waters around wrecks of sunken warships.
If you're interested, it's just started now, Sunday BBC one 8 p.m.
I think there's about 4 1-hour programs in the series
For those of you not in the UK, maybe you will get the series on your own television sometime in the future.
