WEBVTT Kind: captions Language: en 00:00:03.500 --> 00:00:07.340 The overall goal of the project is to see what's out there, 00:00:07.340 --> 00:00:10.000 find sensitive habitats and protect them. 00:00:10.000 --> 00:00:16.500 So, the kinds of sensitive habitats the Bureau of Ocean Energy Management wants to protect 00:00:16.500 --> 00:00:21.600 are in this context, of the whole cruise, are in three different categories: 00:00:21.600 --> 00:00:24.420 the canyons, the seeps, and corals. 00:00:24.420 --> 00:00:28.060 But all sensitive for different reasons. 00:00:28.060 --> 00:00:32.900 The physics is different, the gas fluxes are different. And when you move from the canyons to the seeps, 00:00:32.900 --> 00:00:39.000 here you've got, these are depositional environments that had really high organic inputs 00:00:39.000 --> 00:00:41.800 a long time ago, tens of thousands of years ago. 00:00:41.800 --> 00:00:47.260 And as that organic carbon has been cooked and ruminated in the sediment, it produced methane. 00:00:47.260 --> 00:00:50.800 And that methane is now seeping out of the seabed 00:00:50.800 --> 00:00:54.600 and fueling all of these organisms that can feast upon methane. 00:00:54.600 --> 00:00:57.900 I think of a little bit as Earth's kidneys. 00:00:57.900 --> 00:01:04.520 It's pulling in material and recyling material and putting the good stuff back in and taking the bad stuff out. 00:01:04.520 --> 00:01:10.620 We all have hitchhikers right? We have our microbiome in our skin and our ears and our nose, whatever. 00:01:11.700 --> 00:01:18.700 So the Beggiatoa, these sulfur oxidizers, that live at the Pea Island Escape, they are very long filaments. 00:01:18.700 --> 00:01:23.180 So they're long, they're mobile. They move around, they can cruise up and down. 00:01:23.180 --> 00:01:29.520 They set themselves up in the perfect chemical gradient where they have all the substrates that they need. 00:01:29.520 --> 00:01:35.180 So if you were a free living microorganism who wanted to set yourself up in the perfect chemical gradient, 00:01:35.200 --> 00:01:37.920 but you weren't modal, what would you do? 00:01:37.920 --> 00:01:38.760 You would hitchhike. 00:01:38.760 --> 00:01:40.660 You would jump on a Beggiatoa. 00:01:40.660 --> 00:01:46.760 So, these Beggiatoa are essentially colonized. They're kind of like the bus system at a seep. 00:01:47.740 --> 00:01:54.740 In two days, Mandy will be the first person ever to visit this newly discovered seep that we're calling Pea Island. 00:01:54.740 --> 00:01:57.420 Someplace that people on Earth has never been before. Yeah. 00:01:57.420 --> 00:01:59.220 And that's the coolest thing ever. 00:01:59.220 --> 00:02:03.280 It's like a kid in a candy store. (laughs) 00:02:03.280 --> 00:02:08.920 There's nothing that makes my eyes twinkle like really thick Beggiatoa mass. (laughs) There just isn't. 00:02:08.920 --> 00:02:10.060 There just isn't.
