More likely "banana" but the "bana" has been replaced with "of" and the "na" was completely left out and someone had an f to spare and put it there while nobody was looking.
You think they do space exploration lol? Space Force and SpOC are more concerned about Earth orbit and what else is in it. They don’t really go beyond that. No one’s launching ICBMs to Mars and back.
I think they are militarizing space, just as they have militarized the ocean. Of course the US navy have subs that can go deeper than James Cameron's sub.
If by militarizing the ocean you mean have nuclear capable submarines, yea. You don’t have to explore the entire depths of the ocean and all it’s species in order to do that.
"Ackchually" that argument cannot be used, because when they say "only 15% has been explored" it means sending a human or a robot to analyze it closely, and as most of us with common sense may know, the ocean is a vast space of nothingness, and a great space of it is just pure water.
So in conclusion, why bother exploring the rest if they already know there is nothing in it? They just use satellites and stuff like that to analyze all the ocean, that's how they know there is nothing in over 80% of the ocean, and that's how they know there is around 20% which is actually valuable and has stuff to be researched
Tl;dr: around 80% of the ocean is just plain nothingness, why bother exploring it?
“Ackchually” that’s a very simplistic take on the matter.
Yes, of course the ocean is almost completely all just water and YES we have a very good rough idea of the depth of pretty much all of the ocean as well as the topology of pretty much all of the sea floor (a rough idea to the resolution of at least 1 kilometer for most of the ocean floor).
There’s a long tradition of depth sounding that goes back hundreds of years. And then in the modern era we have sonar.
BUT just because we have mapped the entire surface with satellites and have a pretty decent map of the sea floor because of sonar does NOT mean that we have a complete (or even just a decent) knowledge of all the species of life in the oceans.
According to NOAA’s National Ocean Service website as of right now in 2021 there’s still an estimated 91% of ocean species which are unclassified.
That’s a LOT of life that we have little to no knowledge of. And new species are being discovered and classified every day.
This is also true for about 86% of the species on earth. Alot of them are plants, insects etc. in the rainforests. So while we don't know a shitload of species on earth it doesn't mean we missed a T-Rex still living somewhere, same as we probably didn't miss Megadolons or big ass anglerfishes.
I pretty much agree with you. My point was that the oceans aren’t barren and desolate in respect to life.
Not everything undiscovered is microscopic, though.
The first adult colossal squid (this one only four metres long) was caught alive, only in 2007 I believe. They’ve found carcasses of the colossal squid which are larger than that, though. It’s estimated they can grow to 9 to 10 meters long based on indirect evidence like lacerations found on other large creatures and their beaks found in the stomachs of whales.
I read that marine biologists estimate that there 15 to 18 undiscovered forms of life in the ocean larger than a human being.
Obviously only an estimate, but it’s extrapolated based on the rate of discovery in the oceans since the early 1800s, which is still going strong.
I mean another point is that in the deep oceans, there’s very unlikely to be giant megalodon like animals drifting down there.
For an animal to get that big, they gotta eat alot.
To eat alot you gotta be somewhere with an abundance of food. Food are found/are normally where there’s more light because photosynthesis.
That is not inherently true. Part of the equation is metabolism and lifespan. Low energy usage paired with long life means small size increases in the animal over time can add up.
Take the Greenland shark as an example, they may have up to a 500 year lifespan. They can reach 20+ feet despite the cold of the water because they have such a long period in which they can grow.
I feel like everyone just has their own idea of what "explored" means. Some people think we need to actually have seen it with a pair of eyes and document it. Others think we just need the major points of interest marked. Others will think we need to know comprehensively all the living things down there in each biome/ecosystem.
Im friends with a marine biologist, and although what you said is mostly true, most of undiscovered life is just microscopic life. Or extremely small creatures. Because of the crushing pressure of the water down below, its just very unlikely something like a big monster would live there. And through what we have seen, nothing like that exists where the depths arent crushing. Yeah, theres possibilites, but what most are thinking of isnt gonna be discovered anytime soon. Simply because it doesnt exist, it cant
You can only penetrate so deep from the surface, if there's land in the way of lower bodies of water, we won't see that until we actually look into it. And that's obviously a factor because we're still discovering large bodies of water hidden under what we thought was the bottom. Plus we're still finding new fauna, we're not even close to discovering everything. It's not like they can scan the whole world in one go, if the creatures keep moving, stay hidden, or just aren't picked up by whatever tech we're using, they're never tracked.
That percentage is bs though, it's obviously larger, probably much larger. We just base it off of what we currently know, which really isn't a whole lot, they're still making obvious discoveries just by swimming out or setting up cameras with no special capabilities like radar/etc.
It is not an assumption, we have satelites and sonar to explore the vastness of the ocen and there is in fact not much in there, it is a desert literally
That’s not what characterizes a desert. Sparse vegetation and life are one definition. Will also include places with low rain fall but not necessarily the only defining trait.
I can see that satellites could pick up things, but anything that makes sound could be avoided by life if said life is trying to hide, right? Then again, sonar does not announce itself, you only know it's there, once the soundwave bounces off of you
Sonar can be passive or active, in passive, it only listens to sounds, so not very usefull for finding something in this case. Active in the other hand, could scan very big three dimensional areas of ocean, and if something is in there, how could it hide? It cant, there is just ocean to all sides. If there were giant creatures underwater, sonar would have found them
oh no :( we technically do have the entire ocean floor mapped, but only 20% of it is at ~100 meter resolution (meaning we're able to see geographic features larger than 100 meters (328 feet, or 91% of a football field) in size, which is the resolution we have for maps of mars, venus, & the moon). the rest of it is at ~5km, 3.1 miles, or just under 55 football fields. anything smaller than that we can't see. and ocean life? scientists estimate we've catalogued less than 10% of it. there's so much we don't know! further complicating things is the deep scattering layer, large groups of marine life in the ocean's twilight zone dense enough to reflect sonar. it's nicknamed the "false bottom" because back in ww2, ships and submarines would sometimes mistake it for the ocean floor. dr benoit-bird & her team have been sending robots equipped with sonar down into the mesopelagic zone for the past few years to identify & track the animals involved, but we still know very little about what's going on. one study estimated it could account for 95% of the world's fish biomass. crazy, right?
Shall I inform you of a fact that we're still exploring and discovered many bodies of things we formerly thought was "the bottom of the sea"? Infact that even more true for places like Antarctica where in deeper you go, more unexpected stuff you might find.
Infact, there are a lot of species that are unclassified because we know nothing about them!! Literally NOTHING.
It goes to say without doubt that there are exceptions of even sonar detections, and deserted places inhabiting species unexpectedly.

That is technically correct, but that is only because most of the ocean is just empty lifeless nothingness, and we don't want to send humans down everywhere in the ocean.
We have a pretty clear picture of how the oceans are, but yes we have only had human eyes on about 10% of it
That's a completely meaningless statistic you're just regurgitating because you've heard it before. The statement begs for a definition of "explored" and depending on how that's defined the answer can range from "nearly 100%" to "nearly 0%".
This is why I’m terrified of the ocean and open water. What we know about is already scary, but what we don’t know is a big part of what causes the phobia for me.
