WEBVTT 1 00:00:33.402 --> 00:00:33.938 Oh wow! 2 00:00:35.768 --> 00:00:36.324 Grab that. 3 00:00:43.155 --> 00:00:43.985 It’s like fishing. 4 00:00:46.018 --> 00:00:46.519 Aren’t they cute? 5 00:00:50.448 --> 00:00:54.189 They’re so dead, yes. Well, we did just decompress them from 1,600 meters. 6 00:00:55.186 --> 00:00:57.317 So these are all from three different iron sites. 7 00:00:58.438 --> 00:01:00.490 One of the samples had a lot of fluffy mat. 8 00:01:01.859 --> 00:01:04.524 This is a fluffy sample and this is the rocky sample. 9 00:01:07.194 --> 00:01:08.518 Or, not so fluffy. 10 00:01:09.359 --> 00:01:12.741 So we’re looking for these Zetaproteobacteria, the iron oxidizers. 11 00:01:13.242 --> 00:01:15.776 So you can see how orange these are, so that’s iron oxide. 12 00:01:16.273 --> 00:01:18.771 And you can even see particulates in there. 13 00:01:21.185 --> 00:01:24.944 I’m interested in microbes growing specifically on the rocks. 14 00:01:26.026 --> 00:01:30.909 Seafloor basalt and silicates in general is the largest continuous habitat on the planet. 15 00:01:31.691 --> 00:01:34.987 And it’s also, there tends to be pretty high biomass at the seafloor, 16 00:01:35.524 --> 00:01:44.691 so understanding who’s there, what they’re doing, and how quickly they’re doing those things has important implications for kind of understanding the global carbon cycle. 17 00:01:45.566 --> 00:01:49.942 This is the side that I’ve taken off. It’s like a little curtain. And there it is on the other side. 18 00:01:50.693 --> 00:01:55.153 And then it filters the water through this, there’s the little hole, here. 19 00:01:55.907 --> 00:01:59.739 And that goes up into the stomach, which is up in through here, underneath. 20 00:02:00.521 --> 00:02:02.941 This is when the geologist says, “ew.” 21 00:02:05.355 --> 00:02:06.441 Well done. On cue.
