What have been the big developments in deep sea technologies?
What do you think have been the really big developments recently that have enabled us to spend more time down there to collect more data, and really, just to learn more?
Well, there's a couple of things. One is the materials that are available now, like titanium and sapphire, crystal in particular, to make high pressure view ports and there's been a big leap forward in terms of pressure proofing cameras to 10,000 metres. The other thing is data storage as well. I mean, you can get terabytes of in situ storage which is pretty good but our only problem normally is that we've obviously got to make this jump from standard video to HD. At the moment, handling that volume of HD video in terms of memory is becoming quite problematic.
