WEBVTT 1 00:00:09.562 --> 00:00:17.805 We are beginning Dive 5 of expedition 3 of Okeanos Explorer’s 2014 sojourn to the Gulf of Mexico. 2 00:00:18.562 --> 00:00:22.923 We’re in the northwestern Gulf of Mexico and you’re in for a treat today. 3 00:00:23.477 --> 00:00:25.258 We’re looking at not one, but two shipwrecks. 4 00:00:28.059 --> 00:00:35.172 We’re really lucky to have a number of archaeologists on the phone today and who will be interpreting as they see. 5 00:00:35.728 --> 00:00:38.262 And they’ve had a couple of years to think about what all this means, 6 00:00:38.508 --> 00:00:42.586 what these different ships might have been doing, why they might have sunken so close together, 7 00:00:43.340 --> 00:00:48.588 why the artifacts on the wrecks differ from one ship to the other and what they might have been carrying at the time. 8 00:00:54.091 --> 00:00:57.474 We will begin at the stern of Monterrey C. 9 00:00:58.227 --> 00:01:00.261 We will not be violating the wreck perimeter. 10 00:01:00.761 --> 00:01:11.258 Our goal is to try to station Seirios over the center line and mid-ships of the wreck and then operated D2 around the entire perimeter. 11 00:01:12.559 --> 00:01:16.391 Monterrey C is only 29 meters long. 12 00:01:17.927 --> 00:01:22.230 We’ve got a 30-meter tether on D2. We think we might be able to get away with that. 13 00:01:22.763 --> 00:01:26.304 We’d like to minimize ship and Seirios movement if we can. 14 00:01:31.139 --> 00:01:35.389 We’re going to be extraordinarily careful. Bear with us, we’re going to be moving very slowly today. 15 00:01:36.169 --> 00:01:41.806 We don’t want to kick up sediment with thrusters, D2 thrusters, around the perimeter of the wreck. 16 00:01:44.595 --> 00:01:48.091 So this is part of the rudder assembly. Is part of the steering assembly. 17 00:01:49.586 --> 00:01:52.229 It’s the hinge for the rudder. 18 00:01:53.980 --> 00:01:57.843 What these have been made out of. I don’t see any life really growing on them except a few little tubeworms. 19 00:01:58.341 --> 00:01:58.643 Brass. 20 00:02:01.920 --> 00:02:03.978 Couple of things that we’re trying to do here today, is 21 00:02:05.012 --> 00:02:13.171 with regard to the biological growth on the wrecks is compare the differences among different habitat types, or material types in this case, 22 00:02:13.972 --> 00:02:19.345 whether you’re looking at ceramic or glass or leather or metal or concretions or copper, 23 00:02:20.646 --> 00:02:23.481 the case of the sheathing around the base of the ship, this first ship, 24 00:02:24.261 --> 00:02:28.842 and also not just comparing those between materials and between the ships themselves, 25 00:02:29.595 --> 00:02:33.221 but comparing that to the life forms that we’ve been seeing the last few days at the brine seeps and the oil and gas seeps 26 00:02:34.259 --> 00:02:42.588 and in the canyons. These are the kinds of life forms that live naturally at these depths, 27 00:02:43.086 --> 00:02:49.345 but we’re going to be wanting to know if it looks like there’s differences in the relative abundances here versus other more natural areas in the Gulf, 28 00:02:50.088 --> 00:03:01.763 and what that might say about the impact of manmade structures being added to the Gulf of Mexico in the form of pipelines and platforms and windmills eventually and things like that 29 00:03:02.345 --> 00:03:04.925 and how that might influence life forms around the Gulf. 30 00:03:13.430 --> 00:03:15.811 You can see all that shell hash on the bottom below. 31 00:03:16.553 --> 00:03:21.929 That would be the remains of those shipworms that destroyed the wood of the ship over time 32 00:03:22.973 --> 00:03:30.595 and they’re not actually worms, they’re mollusks, they’re not worms at all, but they eat the wood of the ships and they have forever. 33 00:03:31.338 --> 00:03:32.837 And that’s the downfall of most ships. 34 00:03:36.011 --> 00:03:45.338 Trying to get a measurement on that will be helpful if ultimately working with the overall dimensions of the ship to determine its size and tonnage. 35 00:04:05.060 --> 00:04:10.845 This makes it really clear that she is all the over onto her side because what you’re seeing there are the chain plates 36 00:04:14.341 --> 00:04:17.678 on that side of the hull which can come up and attach the rigging to the mast. 37 00:04:43.889 --> 00:04:49.222 It looks to be glass with a rim. I think it’s an instrument of some sort. 38 00:04:49.978 --> 00:04:50.976 Ah. Okay. 39 00:04:51.975 --> 00:04:55.262 Do you see what could be a dial, a hand inside of it as well? 40 00:04:56.260 --> 00:04:57.504 As if this is a chronometer? 41 00:05:01.143 --> 00:05:06.013 We’ll do this for another five or ten minutes and then we’re going to get ready to transit to Monterrey A. 42 00:05:11.346 --> 00:05:13.589 The operational tempo here will be the same. 43 00:05:14.098 --> 00:05:21.888 We’ll be looking at the perimeter of the starboard side first and then the port side without violating the perimeter of the wreck. 44 00:05:22.389 --> 00:05:25.723 We will keep D2 outside the wreck and look in. 45 00:05:34.346 --> 00:05:35.590 For those of you out there who are not 46 00:05:38.341 --> 00:05:44.098 aficionados of this wreck, we are now looking at the stern and we are about to start moving up the starboard side. 47 00:05:44.844 --> 00:05:49.591 This is a wreck that’s been visited by Okeanos for the first time in 2012. 48 00:05:53.839 --> 00:05:58.429 That’s a cannon in the center, right hand view. We’re going to want to take a good look at that. 49 00:05:59.172 --> 00:06:04.592 And the stove is the upright structure above and to the left of the cannon. 50 00:06:05.091 --> 00:06:05.891 We’re going to want to look at both. 51 00:06:36.265 --> 00:06:38.546 I do think it’s about time to call it a day, though, folks. 52 00:06:43.178 --> 00:06:46.044 Is there anything else burning that you need to see before we leave? 53 00:06:47.044 --> 00:06:51.123 I think we’re done, folks. I think we can button it up. 54 00:06:53.376 --> 00:06:55.127 Bravo, you guys. Bravo, everybody.
