Global Underwater Explorers join Nekton on its first mission in the NW Atlantic.

[Music] we were basically college kids and the dream was to be like Jacque Cousteau right so go travel around the world exploring places [Music] [Applause] project baseline started as a as an outgrowth of us sitting around telling stories about how it used to look in the past we mix that with global underwater explorers as our conservation initiative and leverage the fact that we have 10,000 divers around the world ultimately we'll be able to see how things are changing at all these different locations around the world Nicktoons mission to conduct the XL Catlin deep ocean survey is actually done in three different parts right at the bottom of the ocean you've got the ROV the remotely operated vehicle then you've got our submersibles but at the top you've got the technical divers and they're just prepping for a mammoth dive today let's go meet them most scuba divers in the world are diving from a single tank and they're diving what's called open circuit scuba so they're taking gas from a high-pressure gas source and the regulator that's in their mouth is adjusting that down so they're breathing that in at ambhi we're using a rig that's now instead of it being open circuit scuba it's now called closed circuit scuba so when we exhale that gas is reused we don't use all of the oxygen that we breathe in we only use a couple percent of it each breath that gets recycled this system works as a system of our lungs and this counter lung so when we exhale goes into our counter lung it's driven through the soda-lime material that pulls out the carbon dioxide and then the rest of the gas the balance of the oxygen the nitrogen and the helium goes back around meredith and the team are down it's about 45 minutes is there probably something like that you're actually down at the level they need to be at but then it takes two three hours to decode to decompress all the way up I mean hours five hours 90 meter diving is something that a very small population of the diving world does we have to make sure we follow checklist if you if you miss steps and you get cavalier with this equipment it can hurt you and we're doing things that the human body wasn't meant to do Meredith I would love to try this on I would love to see what you guys it could've come in to handle first what you're gonna do is a shimmy and arm and pick a side okay yeah sure shimmy an arm in there like joy there love yeah oh my oh that's amazing thanks so much for talking me through all I already had amazing respect to you guys but my word I love the science and the tech and the physicality of it take a breath off that now this one on the surface it's all oxygen we don't get the helium from them is that it hello thank you very much Meredith that was very interesting awesome waiting to vote yes and I'm back to normal [Music] so it's about five minutes until the divers splash they're really focused they're doing their pre-breathing right now [Music] so told me three Todd what so what's going on right now very very important yeah so kind of relaxed because the ship has to position itself and everybody's like just let it went when you know so it's gonna brush on today we're going to jump in and go to 300 feet we're going to collect several types of samples for the science team so you're gonna be under for how long between five five-and-a-half hours just incredible from here we're about two miles offshore we're gonna run about one one and a half so what happened to miles we're gonna finish this dive basically right now so this kit is incredibly incredibly heavy when they're up on land of course when they get in the water they can adjust their buoyancy to keep them on the surface or to take them down but this is really hard work right now and they're off there in the water so they've just scooted out to the boy and then they're gonna take that really really long the line that succession of transects all the way in to the shore are gonna be out there for five or six hours the divers are much more dexterous they can move into environments that the subs physically can't fit into and what might take five minutes to position the sub in such a way to get a manipulator to grab something and then they can only hold that one thing or put it into a box very slowly we can just collect a lot of things and move very rapidly the subs can go to a thousand feet and we can go we can start at 300 and between the two of us we can cover this huge range of depths that go from a thousand all the way to the surface so it's a way to increase the productivity of the submersible dive [Music] [Music] an outstanding dive reef all the way I had a yellowfin tuna with a fishing line in his belly swam with me the whole way we moved our way in and along the way we've just got a buttload of science I mean we got coral and algae and I don't really think there's a lot of dive skill out there that can do what we do these scientists need this data they need samples they need things they can study and in and look at and when we're down there we can do so much because we're nimble Todd and I call it picking weeds for science we got divers all over the world that are doing this or can do this any day any day of the week and that's what's really amazing to me is just thinking about the potential [Music] essentially net Khan's mission is to establish baselines basically in the deep ocean and you know we're focusing on the shallow part of the ocean to me and send just a natural collaboration [Music] this is the coral here that's the coral we got from shallow boy oh boy here's the what so you carrying this alone as you're 90 meters this is a coral from here just keep holding yes how are you feeling now you still seem pretty perky but shitty you shattered a little bit of food and I'll be okay whenever we go out someplace now we're recovering a much bigger portion of the oceans that not too many people are looking in we're literally going places that nobody's ever been before and we're recording it in a way that is going to be productive for the conservation of the oceans it's not really a job right it's an opportunity to to engage with life in a way that is you know much has a return [Music] you getting a grind on your like a regular day job and use do your work and come home but now you have this opportunity to really get involved with something that's potentially a lot bigger than than any of us individually [Music] you
