The ocean is the largest ecosystem on Earth, but it's still mostly unexplored. This is partially due to the challenges of ocean exploration, like bone-crushing pressure and the need to bring your own air. But here are five ways that we've pushed the limits of where we can explore.

    ~Did you know?🌊 According to the Telegraph-Journal, british scientists have discovered for the first time In december 2007 waves that flow deep in the Pacific Ocean, Scientists were surprised to find them in the deep ocean... They used in this discovery satellites, submarines, and floating laboratories. Amazingly, Qur'an has mentionned this fact +1400 years ago: "Or [they are] like darknesses within an unfathomable sea which is covered by waves, upon which are waves, over which are clouds - darknesses, some of them upon others. When one puts out his hand [therein], he can hardly see it. And he to whom Allah has not granted light - for him there is no light."

    #plandemic #REOPENtheWORLD #RESISTorbeCONTROLLED 1) Why would nations ACTUALLY trying to END this event take so long to do so (~1 yr), if it's so bad? 2) Why would they repeatedly INVENT new variants and hype up their danger on TV, while rarely discussing vaccination (the REAL solution)? 3) Why does this EVENT severely affect people in need, but adequate aid is DENIED? 4) Why does the #plandemic make people afraid of EACH OTHER, lead to massive economic fallout, 'cause small business closures, induce mass unemployment, FORCE children out of school/activities & yet is not being handled? 5) Why do "leaders" keep asking for more 🕙 to solve a problem that doesn't give you any? Why don't they just have MORE PEOPLE WORK ON IT & END IT ALREADY?! Answer: The #plandemic is a DECOY & SCAM to create a disaster economy, while also preventing public mobilization against the collapse of civilization. Prove me wrong 🤷 Meanwhile, Gaia (🌎) which DOESN'T CARE if you're PARANOID, is preparing to ANNIHILATE humankind anyway.

    For Context that "Exosuit" filthy name I prefer the Newt Suit. It can stay underwater for a bare minimum of 6 hours, and it has enough Back up Oxygen/Lifesupport for 2 Whole days! It is used normally for dives up to 300 meters, but it has been tested to function at even 900 meters deep. The main difficulty in an Atmospheric suit design is surprisingly or rather unsurprisingly the Joints. Because somehow they have to make it flexible enough that you can move it but at the same time also survive the immense pressure pushing down on it.

    A disappointingly "Oooh... it lets us see new fish..." take on the technologies of ocean exploration. Where is the Argo programme which offers a near realtime view of temperature, salinity, and increasingly chemistry in the upper 2000m of the ocean? Where are the various radio altimetry (TOPEX/Poisioden, JASON) and scatterometer (QuickScat) satellite that have given us near realtime pictures of near-surface winds, sea state and sea surface topography (from which we can derive ocean currents) for most of the last 30 years?

My long term dream is to live on a boat, and I imagine it would be really cool to have a semi-permanent drone below the boat streaming to a big 4k TV as a kind of "underwater window". Well maybe it depends on the location if that would be cool or ugly haha. I imagine building something like this yourself wouldn't even be that hard

      Well even at the surface of Venus that submersible pressure suit would take the pressure as its similar to 1Km under the ocean. The upper atmosphere of Venus is comparable to Earth, about 50Km up. Venus surface = ~ 90 atmospheres, deepest part of the ocean = ~ 1100 atmospheres

    Concerning maintenance of robotic probes in the ocean being easier than those in space: In the 1960s, if I remember the date correctly, MAD Magazine had a really hilarious cartoon. In it you see a person in a suite looking, in sticker shock, at a Bill for a satellite repair that has a LOT of zeros. Behind him is this really scruffy guy smoking a cigar with the label "NASA Satellite Maintenance" on his beaten-up baseball cap. He simply says in his word bubble, "We had to take it to the shop." One of the best cartoons ever...

    Question. Why couldn't we put an inner space station at the bottom of the sea where things like submersibles could dock to exchange crewmembers? We already have submarines that can stay under for over a week. Why not an international Ocean station?

      Crew would probably rather live on a boat in that case. And you can take your submersible all over with a boat rather than being stuck adventuring out from one spot. They've done this stuff for more shallow diving (SEALAB was a big one back in the 60s) and that way the crew could live at pressure and not need to decompress. But for sea floor type stuff (at depths where humans can't currently survive the pressures, I think 700m worth of pressure is the record and that's short term in a controlled environment) you're just adding another point of failure and a very expensive structure.

      My guesses would be that 1.) You would be damaging a potentially sensitive ecosystem by dropping a giant base down there 2.) Maintaining such a structure would be incredibly dangerous, difficult, AND expensive 3.) Aid would take forever to arrive were an emergency to occur down there and you'd have to find some way to contact the outside world that doesn't involve cell-phones or the internet because you wouldn't get any sort of satellite or radio signal at the bottom of the ocean 4.) Your only viable option for powering such a station would be nuclear because you're nowhere near any electrical grid which is again just really really expensive considering how risky the entire undertaking would be 5.) It just doesn't make much sense to go through ALL THAT just to hunker down in one single spot when it's just far far cheaper and simpler to do short missions with subs and ROVs wherever you want whenever you want

    I swear music for scientists is spending more on advertising than they will see in revenue

      Yeah, same thought. It’s also just not how you advertise music, you advertise music by playing it. Not sure why they don’t intro and outro with a handful of seconds of the actual music

    This took me back to second grade when we got to read about the Alvin submersible and I think Jacques Cousteau...? It was 30 years ago and I remember being fascinated by the deep.

    The Nautilus live streams their ROV searches, they are an excellent source of information! Thanks for making a video on this amazing topic! :D

    Hypothetically speaking, if a giant wall were to come out from the core to well above the water level all around say, the equator, separating the earth in half, including the oceans, would that effectively half the effect of water pressure as well? Or is water pressure more about the water directly above you at any given point rather than the total amount of water spread out above you?

      @BPF okay, thanks!

      It’s the pressure of the water directly above you. 1 foot is equal to .445 PSI, regardless of the volume.

    So if the divers were to speak while diving, will their voices sound like chipmunks due to the helium?

    Re: trimix breathing: why do they use helium (which is very rare; found only in certain natural gas wells) instead of argon (which makes up approx. 1% of our general atmosphere) ?

      Helium doesn't have the narcotic effects that nitrogen does on divers and isn't as dense. So it isn't as increasingly difficult to breath mechanically at depth and doesn't disorient divers more at the same time. Argon however is twice as narcotic as nitrogen and denser than air so it would disorientate more and be more difficult to breath. It is however used by divers to inflate their drysuits as it has better thermal qualities.

      Bet it has something to do with the fact that helium is very light.
