00:00:09.333 --> 00:00:21.333
What's really cool about this
site is that there's a really

2
00:00:12.600 --> 00:00:18.333
tall chimney structure, and yeah-
they keep saying it's the largest

3
00:00:18.333 --> 00:00:25.100
biological iron structure. It was
on the back art of the mariana,

4
00:00:25.100 --> 00:00:33.000
So we sampled the bottom, and the
middle, and the top of this

5
00:00:33.000 --> 00:00:37.100
structure. We got scoop samples,
we got slurp samples, and we got

6
00:00:37.100 --> 00:00:39.967
biomat samples. The biomat
sampler is that cassette sampler,

7
00:00:39.967 --> 00:00:44.067
So we get that really fine scale,
community structure. So, the ones

8
00:00:44.067 --> 00:00:47.700
that settle out are - have a lot
more mineral particles in them.

9
00:00:47.700 --> 00:00:51.333
And so those tend to be less
active. and so the fluffy stuff

10
00:00:51.333 --> 00:00:54.467
is where we think we have the
active zetaproteo bacteria. See?

11
00:00:54.467 --> 00:00:59.233
Not fluffy. Not fluffy enough at
all. and this is fluffy. We want

12
00:00:59.233 --> 00:01:04.233
fluffy. So what I'm going to do
when I get home is going to

13
00:01:04.233 --> 00:01:07.733
compare these samples, find the
ones that are the most zeta

14
00:01:07.733 --> 00:01:12.167
enriched, so determine the zeta
percentage of the samples and

15
00:01:12.167 --> 00:01:15.867
then I will do metageonomics.
Which means I will sequence all

16
00:01:15.867 --> 00:01:19.900
of it. And then from that I will
determine what genes are

17
00:01:19.900 --> 00:01:23.700
responsible for carbon fixation,
umm how are electrons getting

18
00:01:23.700 --> 00:01:26.433
transferred, so how are they
making their energy, how are they

19
00:01:26.433 --> 00:01:28.433
making a living.
