(electronic music) - [Scientist] You want to go for a swim? - [ROV Pilot] Yeah, let's do it. - [Scientist] It's a
fish swimming above it. - [ROV Pilot] Oh my goodness. - [Navigator] Is it inside
and dead, or is it right up? - [Scientist] It's
actually right above it. - [Navigator] Oh. - [ROV Pilot] It's swimming
right along the surface. - [Scientist 1] Wow. - [ROV Pilot] Oh - [Navigator] That's cool. - [Scientist] You want
to go for a swim, Greg? - [Navigator] Sure. (man laughs) - [Scientist] All right,
let's dunk the basket. You're ready to scan with your mass spec? - [ROV Pilot] Oh my God, that's awesome. (pilot squealing) - [Scientist] Look out. (group yelling) - [Scientist] There it is. - [Group] Oh! - [Scientist 2] Explosions. - [ROV Pilot] Oh, and the waves are going to propagate all along. - [Scientist] Yep. - [Scientist 2] That is so insane. - [ROV Pilot] Look at
it flow along the top. - [Scientist 2] That's so crazy. - [Scientist] There's a wave. You see the wave? - [Group] Whoa, so cool! - [ROV Pilot] Wave propagation
in ultra slow motion. - [Scientist 2] Oh my gosh. - [ROV Pilot] Rivers
under water are awesome. - [Navigator] How are we doing, Charles? There we go. - [Scientist] Oh look, there's out cropping gas hydrate over there. - [Scientist 3] Yep, you
got sulfide too, yep. - [Scientist] You got sulfide too? - [Scientist 3] Yup. - [Scientist] You can see it. The river flowing down towards this. - [Navigator] Well, when
we're ready, I will dry off. (group laughs) - [Scientist] I want to go see
that yellow rock over there. Are you good, Charles? - [Scientist 3] Yep, I'm good. - [Scientist] Yeah, let's go over there. - [Navigator] All right. - [ROV Pilot] Really salty is probably not the best for instrumentation. - [Scientist 1] Whoa! - [Scientist] Uh oh! - [Scientist 1] Oh! - [Scientist] There it goes! - [Scientist 1] Ah! - [Navigator] Like brine and sediment. - [Scientist] Yep. - [ROV Pilot] Look at
the density differences. Looking at it travel
underneath and on top. - [Group] Whoa. - [ROV Pilot] This is very very similar to pyroclastic flows. (group laughs) - [Scientist] Really? - [ROV Pilot] From going
from the air into the water. - [Scientist] Oh, cool. - [Navigator] I knew you were waiting for your vulcanism window. (man laughs) - [ROV Pilot] The
difference in the flow raise is really wild. - [Scientist] Here comes
the wave up on the shore. - [Scientist 1] It's a tsunami! Ah! (group laughs) This is awesome! - [Scientist 2] Best shift ever. (group laughs) - [Scientist] That's
just a strange carbonate. It's not hydrate. - [Navigator] Again, nice
wave break around it. - [Scientist] Yeah. All right, let's come full wide. - [Scientist 2] Okay, going wide. - [Scientist] So, underneath
the Gulf of Mexico, when it first formed, as the
Atlantic was first forming, when the continents split
apart and the Gulf opened up, and filled with seawater
and then closed off and became basically a big evaporate basin and all of the water evaporated out and left all the salt behind. And then when it finally filled up, this was around the same time as the Rocky Mountains
were starting to lift and all the sediment that was washing off of the mountains as they were forming. And most of it ended up
in the Gulf of Mexico. And all that sediment
loading on the upper part of the slope started to
push down on the salt. And the salt starts to deform. It basically bends. Oh, whoa, go up to the top of that. - [Navigator] Yep, I saw that. - [Scientist] So anyway,
there's tons of salt underneath the Northern Gulf of Mexico and then all that sediment
loading crushed it. And it's very slowly moving out. - [Scientist 3] Ah, that ship moved . - [Scientist] Whoa, look at that. - [ROV Pilot] It is like an infinity pool. - [Scientist 3] Ah, ship moved. - [ROV Pilot] They just finished it. Do you want another one? - [Scientist] It is like an infinity pool. - [Navigator] Ah, we
should swing a little bit. - [Scientist] Look at that. There's a lip. That's brine right above us. And it's just starting
to come down the slope. You know what those actually,
could you go for a quick zoom? - [Scientist 2] Yeah, can I zoom in here? - [Scientist] Yeah, crystals there. They're barite. It's barium sulfate. - [Group] Wow! - [Scientist] I've seen
this in other brine pools. Also, you can see, look at the waves. - [Navigator] Look at the shimmer. - [ROV Pilot] Oh, look at the waves! - [Group] Whoa! - [Scientist] That's awesome. There's our thrusters causing a little bit of the wave in there. - [Scientist 3] They're all
in their own different levels. - [Scientist 1] Crabs hanging out. - [Scientist 3] It's water Yellowstone. - [Scientist] Yeah, it's
very similar to that. Different process. It's not hot. But lots of different types
of minerals and bacteria forming all these different colors. - [ROV Pilot] It's so clear. - [Scientist 1] Zooming
in on mussel island. - [Scientist] Mussel beach. (laughs) There you go. - [ROV Pilot] Sure is. - [Scientist 1] Whoa. Those are some opportunistic
suckers down there. (group laughs) - [Navigator] That is risky. - [Scientist 1] There's little ones. - [Scientist] Yeah, really tiny ones. - [ROV Pilot] Looks like some of them fallen in over the years. - [Scientist] Yeah. - [Navigator] But the reason
for some of them falling in as new ones grow, do they
inadvertently push some of the more established
ones out of the way and in? - [Scientist] Possibly. - [ROV Pilot] Crazy. - [Scientist] Then just
get too big and fall off. All right. Should we keep going up? - [Navigator] Yeah. - [Scientist] What's next?
Sounds like a bunch of stoned scientists.
Their fascination is contagious.
That was extremely fascinating and such a pleasure to see, thank you.
I dream of the day when a robot can do this on Europa, or Titan.
wtf am I looking at
I just reread my title after getting some sleep... I am disappoint.
I didn't know that beach in spongeBob was scientifically accurate.
Where's the sub for cool underwater footage?
That is friggin cool
