WEBVTT 00:00:04.640 --> 00:00:08.160 These seamounts that we are diving on were once active volcanoes, 00:00:08.800 --> 00:00:10.960 but they are quite old. So 00:00:12.080 --> 00:00:14.880 Kelvin Seamount has not been directly dated before, 00:00:15.520 --> 00:00:22.240 but based on the ages of nearby seamounts, I would estimate it to about 92 million years old. 00:00:26.640 --> 00:00:30.640 I don't think we've seen such well-developed ripples on any of the sediment surfaces. 00:00:30.640 --> 00:00:34.080 Certainly not over such a broad area, we've seen a few in small patches. 00:00:36.400 --> 00:00:37.680 So this is really interesting. 00:00:38.400 --> 00:00:42.960 We have just tremendous diversity, but there's not a lot of numbers of each of the species, 00:00:42.960 --> 00:00:47.440 but there's a lot of different species here. So that's one measure of biodiversity is 00:00:47.440 --> 00:00:50.720 just how many different species we see. It's something called species richness. 00:00:53.760 --> 00:00:58.480 Really nice view in Seirios camera if you want to see what the Deep Discoverer looks like when it's 00:00:58.480 --> 00:01:02.640 working on the bottom of the ocean here. You can see really well the slope 00:01:02.640 --> 00:01:06.400 as well of this feature. Yeah, I have to say what gets 00:01:06.400 --> 00:01:12.000 me really excited is when I see a lava flow that has these really distinct features on it 00:01:12.000 --> 00:01:15.520 that can let me imagine what it looked like when it was actually erupting. 00:01:16.160 --> 00:01:19.600 To get a sense of how the rheology of the law, how it flows. 00:01:20.480 --> 00:01:25.360 At one point, this was not solid rock, this was actually moving and changing its shape. 00:01:25.360 --> 00:01:28.560 I just find that really exciting about volcanology in general. 00:01:32.960 --> 00:01:38.640 Well, it's been an outstanding dive. And perhaps all the more remarkable given that 00:01:39.520 --> 00:01:42.960 at about 6:30 or 7 this morning, we didn't know that we would have 00:01:42.960 --> 00:01:46.560 a dive because the Gulf Stream is moving through the area so rapidly, 00:01:46.560 --> 00:01:50.640 that we weren't able to work here because the ship wouldn't have been able to be 00:01:50.640 --> 00:01:53.840 stable enough for the ROVs to work on the bottom.
