I'm 17 (so you get an idea of the level i'm at) and have to write a 3000 word report, and i have chosen about the difficulties of studying deep sea organisms.

I'll write about how observing them with submarines isn't effective as the noise and lights are distracting, but how we can use technology to take samples and analyse it to find out more about the creatures. (we also have to go on about the economical etc impacts of the methods)

So far i've only found the nanodrop machines and am investigating if they're used (I've emailed the company and posted on here specifically about it). But can anyone else point me in the right direction about other analytical methods possibly of  DNA, and what kidn of data scientists recieve from the experiemnts and what they can deduce from them?

Thanks, nix :)

Please read article from Lymin, Siegel and Russian workers they have done good work on marine animals mostly electrophysiological recordings.

Hi Nix!  Other than nanodrop technology, you can also do things like PCR on samples to look at large genetic arrays, and also DNA analysis by gel electrophoresis.  With PCR, you can uncover difference in genetics that might give insight into differences between species that live in the harsh, deep sea environment vs. those that live in the more moderate ocean environment.  With gel electrophoresis, it is possible to uncover genetic differences that arise between species by using enzymes that clip the DNA at certain sequences.  This will result in shorter fragments that will appear on the gel if that sequence was present.  If not, the fragments will be larger and thus you can distinguish between species.
