Marie Tharp's topographical maps increased our understanding of both the ocean floor and the processes that move the earth's crust.

The Scientist Who Mapped the Seafloor: Marie Tharp | Great Minds
831 Shikime 84 mijë
I really truly wish that that was the only thing that "sounding" ever meant.
She also advanced appreciation of the female of our species. The male since the beginning of our time did just the opposite, couldn't stand to not have someone to put down and dominate. Most young men today have at least a decent view of women for the most part. I thought we'd never get here. Thanks, guys.
Never heard of her and I'm glad I now have. What a woman.
Really good summary.
Hank...I subscribe to this channel. Today my introduction assignment in Paleontology was to write about a "dead geologist" and I chose Marie Tharp. Pop on ALfirst to get my details straight..5 days after you made one. Weird timing, but also weird that YT doesn't show me videos from one of the few channels I sub.
Wegener lit the torch, Tharp carried it. Wegener died before his theory of continental drift was accepted, and was ridiculed during his entire carrier.
Nice
Chicks, man. Am I right?
Never underestimate women's minds ! #MarieTharp100
Oh hey it's the guy from Tiktok
The amount of effort it'd require to map out the entire ocean floor, boggles my mind.
Truth be known, it was that darn girl talk that first suggested the earth was round not flat... 🤣🤣🤣🤣 WOMAN hush that girl talk lol
typical girl talk
Lmao " girl talk " ... look how far we've come .
So...it used to be easier to believe that the earth was FECKING EXPANDING, like in gaining mass OUT OF THIN AIR on a very alarming rate, with all the clusterfuck that such a ludicrous idea comes with, than to accept that the masses the earth already has were moving around and redistributing...because a woman happened to be the one to propose the later? I understand sexist people are not the brightest tool in the shed by default but this seems like a whole other level of pure collective idiocy.
Sounding replaced by sound
Who tf dismisses something by saying it's girl talk, wtf?
Neat
I heard bout that Marine Garp 🤣
Ok here's a question though. How come a female's immune system doesnt kill sperm when she gets pregnant
We have come a long way in that we can see now that saying something like, "that's just girl talk," is wrong on so many levels, and that's a good thing. But we still have a long way to go because there are men out there who still think like that.
Having worked in a research institute, there are still way too many male scientists still think like that.
Ah the 1950s. When women could be snipers and spies but couldnt be researchers on boats.
Crab Check: No. There are no crabs in this video.
Wow, not so helpful
ALfirst: We must add context to keep people properly informed on Climate Change and Baseless Election Fraud Allegations and COVID and also the Bermuda Triangle because god forbid.
The world needs more "girl talk".
"The earth is getting larger" this is on par with geocentrism!
Heezen was a idiot.
I bet Atlantis is at the top of that submarine hill in the Black Sea.
What an amazing contribution to Geology and Earth Science Marie Tharp made with the discovery of the Mid Atlantic ridge!
Thanks Tharp
the discovery of the atlantic and pacific ridges gave credibility to the hypothesis but the crucial data that confirmed it was the discovery of the symmetrical magnetic banding either sideve the ridges
Plz do a video on activated carbon.... thanks your a great ALfirstr
What exciting science. Thank you Marie. It's sad she wasnt taken seriously and was dismissed because of her gender. It makes you wonder how much culture and science and everything else we've lost over the years thanks to misogynistic dismissal of women's ideas
We still haven't found a huge jet in the ocean yet
Why is ALfirst linking a Britanica article about the "supernatural" elements of the Bermuda triangle? Kinda delegitimizes this perfectly fine historical and scientific video, like it is also about supernatural and unexplained phenomenon.
There's a lot of great ideas in Girl Talk. I feel like we should pay attention to it more. Maybe instead of mansplaining how they're wrong.
Is there a spot in the ocean called "Girl Talk Valley"? Would have been nice she had embraced it to make her point.
"And We have built the heaven with might and We continue to expand it indeed." (Holy Quran 51:48)
There's bias and prejudice in every field of study and it's hindered the advancement of mankind. Especially when a woman or a person of color makes a breakthrough discovery that can change the way things are traditionally done. It's no surprise she was initially treated that way. There's an even bigger divide when the rich kill innovation and stifle change by suppressing inventions and discoveries that could benefit many but hurt their pockets!
☕️☕️☕️
"And We have built the heaven (space) with might and We continue to expand it indeed." (Holy Quran 51:48) its big bang....revealed in 1400 ago..
If only 6% of the ocean floor has been mapped 'in detail', why do maps of the ocean floor (as seen in this video 04:30 and elsewhere) look so detailed? I guess the answer has to do with what you define as 'in detail', which has to do with spacial resolution. But the maps look pretty detailed to me -- so what am I missing?
@3:29-No to continental drift. That theory postulates that the continents ‘plow’ or ‘drift’ through the oceans. You meant plate tectonics
Ooh yes... The king of girl talk that I actually enjoy.
Shouldn't sound move slower through denser water?
How does the Expanding Earth theory make more sense than tectonic plate theory to the scientists in the 50s? Are they high on LSD?
I wonder whether if Tharp had been a man would we talk about the Tharp Ridge? When I taught History in a girls' school I decided to create a display on the stairway to the History Department showing women who had made significant contributions to the modern world. I gave up as there was so little information readily available at the time. So glad to see videos like this, even though I am now retired and have no practical use for them.
Where did they think the extra volume was coming from?
Some people thought it was thermal expansion, but they never managed to give a good explanation of what was heating the earth's core. Some other people thought that the earth was gaining mass by absorbing stuff from the aether (which of course does not exist).
The ocean is also home to other intelligent life. Like more intelligent than humans
None of which would have been possible without Reginald Fessenden, a man, who invented sonar.
ScimanDan debunked a video from an expanding-earth believer just three days ago. It probably is due the fact that this person is not a girl that makes him belief such nonsense.
Girl talk, pfff. By that time women also were not allowed to have a position as researchers and get a doctorate, or be a professor on a university and have a laboratory. Many women were human computers, with the annoying task of actually analysing data and do the actual thinking. I will not even start about black women. It's an outrage.
I understand your sentiment. Your statements may generally be true, but they are not exclusively true. The most immediate example which enters my mind is Virginia Apgar, M.D.. She graduated medical school in 1933. I know she is an exception, but there were pioneering women out there.
S...sounding? Huh........
You say as of 2017 there is only 6% of the ocean mapped, but you show her maps that look like they cover most of earth? How is that only 6%?
@SMK-82 Yeah but when he says 6% and like we have no idea what's down there, that sounds a bit extreme, its not like we don't know. Plus if the entire ocean floor is mapped regardless of the resolution you can't say its only 6%
Mapped in detail. think of looking at a painting from far away, and then looking at it really up close. From far away you see the picture, up close you can see the individual brush strokes.
Could somebody explain to me why the rift valley in the ocean contradicts the hypothesize about the growing Earth, please? I don't get it ¯\_(ツ)_/¯
That is some pretty awesome girl talk!
3:00 wtf. That sounds so dumb and about as likely as those Hollow Earth myths. I can't believe that was actually taken seriously in the 20th century.
There are still some idiots who still believe in that. Thankfully, none of them are even remotely taken seriously in any academic circle.
You had me at "Meat Layers"! Gotta love this channel!
Dunno how knowing the details of the ocean floor is that important. It's not like real estate developers are going to be putting cities there anytime soon and need to know which areas to avoid.
Any chance of a Great Minds episode on Émilie du Châtelet?
In 1968, I had a science teacher who not only didn't believe in continental drift, he didn't know that the theory existed. He said that the S. America/Africa shapes were just coincidences and that continents didn't move. I had such great teachers.
alfirst.info/load/nWtncme8arqCq5s/video Carl Benz - Biography
I loved this informative video, like most of this channel. Sadly I keep hearing about sexism though but it’s okay
Girl talk eh?
*Just a friendly reminder to NOT google sounding* ❤️
Anyone else super disgusted with misogynistic BS, especially in the past? I am embarrassed to be a man at times🤦🏽♂️
Why there's no playlist of "great minds'
Uh, there is?
DOGECOIN TO THE MOON!
Alfred Wegener: Hey, the continents look as though they fit together, so the surface of the Earth must be drifting. Everyone else: You're a crackpot, mate. Marie Tharp: I've found evidence proving the surface of the Earth is drifting. Everyone else: That's just girl talk.
Did these scientists think the Earth was slowly heating up? Or did they have an idea for how matter was getting inside the Earth?
I need more videos on female scientists. Thank you so much for making these.
I only realized yesterday that google maps' satellite view also has ocean depth data spliced in Never knew the north sea was just a big shelve, or that the pacific has such steep edges
Marie Tharp's story is amazing, and doesn't end in just this 5 minute video. I Highly reccommend the biography written about her: Soundings, by Hali Felt. It's written as part a regular biography, part Felt's own journy uncovering Thrap's life, and part novelization of scenes from actual events.
I remember looking at the inside covers of the Encyclopedia we had at home. I was maybe 7 or 8 years old and I loved looking at these grooves in the middle of the oceans. I would imagine big underwater mountain ranges and deep sea creatures Thanks Marie Tharp Rest in peace.
What kind of regulation forbids women on ships? Was this from the time people thought women on ships bring misfortune?
Man: Dismissed woman's work because she's a woman... Woman: Remembered for making a major discovery about the Earth while the dismissive man is forgotten... :P
@Mendicant Bias "Whether they deserve it or not doesn't change what it is" What? You mean to say you'll have a problem every time a minority of the past deserving of recognition is praised? Also, again, you're right. Today, we don't lift women scientists on a pedestal and sing their praises; we treat them like normal people doing science things. That's because in today's day and age, doing science isn't gendered (mostly!) like it was in the past. Today, it is delightfully normal (again, 'mostly'). Almost all Nobel Prize winners of the past in science are men. Like Tharp, women had to fight off demeaning phrases like 'Girl Talk' and peer attitudes that did not help their careers. Their discoveries were stolen and cited as men's discoveries. And I'm sure you know the absolutely tragic story of Alan Turing. So yes, these people are DEFINITELY Icons Of Representation for their time, and should be remembered as such - they stuck with the science in the face of people who blew them off. Like you are now, too. A current, history-in-the-making example, non science related, is Kamala Harris. 20 years in the future there will a video talking about her and a Mendicant Bias will call it affirmative action, "whether she deserves the recognition or not". Nevermind the fact that every VP before her was a white, old male. Nevermind how significant a fact that is. Nevermind that she will be an icon for other aspiring black and women politicians. No. She's not being treated like any other white, old, former VP so it's "affirmative action".
@Stephanie D'Souza Whether they deserve it or not doesn't change what it is. As for when it's 'normal' recognition, that'd be when they're spoken as just scientists rather than icons of representation. At least two of the three videos I linked, as well as this one, specifically highlighted the role their gender or color played in their lives, as opposed to simply detailing their accomplishments (the third was more ancient, so we know much less about her - that one was more about correcting historical perceptions). There are videos on Curie that do that too I'm sure, but there's also plenty that simply explain her work and its significance. Or consider all the female scientists who've shown up on Brady's channels (Numberphile, Sixty Symbols, Periodic Videos, etc.). They never seem like they're being paraded out to be icons of womens' representation in science, even if they may still be doing that for some viewers. Some have even gone on to make their own channels too, like Dr. Becky, and they still don't come across like they're trying to preach in their videos. Neither do people like Dr. Sabine Hossenfelder, who simply writes off most of the physics community, including male ones, as misguided fools - not because they're male or anything, but simply because (in her view) their science sucks. Anyway, Scishows' videos of this type are nothing like those. They typically specifically play up the role the person in questions gender or race played, to play into the story of suppression. They aren't merely highlighting women or blacks, they're highlighting sexism / racism. And that makes them more clearly identifiable as affirmative action videos. In other words, the difference between just 'normal' recognition and affirmative action? The former don't preach, the latter do. The former are just about the science, the latter more than just that.
@Mendicant Bias can't a woman scientist or a person of colour be spoken about without it being called affirmative action? I get where you're coming from. It's not just Scishow, a lot of content is now centred around women/coloured/lgbtqia people. But they have long since deserved this attention, rather than their ideas being dismissed as things like 'girl talk'. Nobody bats an eye when a video details the successes of a male scientist. Yet when a woman is celebrated its affirmative action? When is it 'normal' recognition and when is it affirmative action? Also did you just randomly pull up 3 Scishow videos of women and a black scientist to solidify your case? Again, at what point can you judge a video as legit or 'a deliberate attempt to highlight more women icons of the past'? Why not pull up every such video made by Scishow?
@Stephanie D'Souza 1) Strange, I even capitalized the 'AND' for you. No, you didn't negate the role of her gender in her dismissal, nor did I suggest that. You did negate the other part, unsurprisingly. 2) If she were remembered purely for her work, you'd have heard of her before (Marie Curie was never forgotten, for instance). Her work was impressive sure, but it's naïve to pretend she's not being brought up now in a deliberate attempt to highlight more women icons from the past. This isn't new for Scishow, they've had several episodes doing it by now (I've linked a couple of them below, for your pleasure, as well as another of a person of color). No, she isn't remembered JUST because she's a woman, but being a woman is certainly a significant part of it. I'm not necessarily against affirmative action in principle, but I'd rather not have people pretending they aren't getting it. alfirst.info/load/Zo2QYWmtkMRefmg/video alfirst.info/load/lpZ_hWqsgpd7X40/video alfirst.info/load/fKyKgobKf7ekZHU/video I know progressives like to treat their agendas as simply the 'it's [current year!]' norm and so not really agendas, as well as their sources as 'obviously' apolitical and unbiased, so feel free to keep believing that (or even better, go watch Hank and his brother's personal channel - vlogbrothers - and try convincing yourself of it). But, for what it's worth, someone who's actually in the middle of the fence is pointing out that her gender was very much a factor in why this video exists. Make of that what you will.
@Mendicant Bias we acknowledge it's a major discovery, yes, but differ on why it is being remembered. 1) absolutely did not negate the role of her gender in her dismissal. Where did I do that? 2) you're right. I'm hoping she's further remembered for her work than her gender. Your first FTFY made it sound like she's remembered just because she's a woman. I hope that isn't the case.
muh sexisims!
Man, I sat here waiting for the part about the bermuda triangle and was massively disappointed! Stupid youtube lying to me like that!
I live around Lamont-Doherty and that is not how you pronounce it hank
Hank !!
I wanna really know what you guys think about the government confirming aliens being real.
Don't hate on me for mentioning that it's not called continental drift anymore. 💖Plate techtonics💕
"Sounding" Boy I'm glad it's not the other type.
Thanks internet...
hahaha
What regulation wouldn’t let her set sail
This whole video is girl talk
wow what a great video yeh nice
I like how the urube fact checkers want to make a post here in the title trying to debunk any Bermuda triangle conspiracy theories. Thoes guys are so lame, I hate them haha.
Don't hate, educate.👍My personal goal is to help just one flat-earther understand how cool and accessible geology is.
I couldn't help but grin when the word "sounding" came up
@Pyro look it up on urbandictionary
Why?
🤣🤣
My wife was on the very first team to map the sea floor under parts of the Antarctic ice sheet that had never been accessible until recently. They did swath bathymetry from an icebreaker.
Wait wait wait, they called it "sounding" when it was just a weight on a string, but then they invented a way to do it with _literal sound waves,_ and decided to call that sonar? Oceanographers are wild, man.
@Peter Schmidt maybe just don't look up the definition on there at all anyway
If you think that's a weird use for the word "sounding", don't look up the meaning in urban dictionary.
Sounding hence the term Mark Twain. 🚣🏻♀️
@Victoria Mark Twain means Mark 3 meters of water. A boatsman would throw a line/ sinker into the water to sound for depth. And Samual Clemons took that for hit pin name. 🚤
I don't get it....
Another assistant in the lab was making maps of earthquakes? since no name was mentioned, I assume it was a sexist and stupid man doing that stupid map. Also, women were aboard many research vessels in the past, it’s just an unfortunate fact that this particular one did not have adequate facilities to accommodate the taboos of the past.
It’s so weird that the measuring method called sounding is not the one that uses the speed of sound
Googling sounding returned interesting results
Using a fathometer, the sonar instrument mentioned in this video, retains that name incidentally enough. You take soundings with sound these days.
Female badass Also: youtube is showing a card for the Bermuda Triangle wiki under this video because somehow that makes sense
Good episode, Hank. It would be neat to see an episode about how the search for MH370 has given us new information about the Indian Ocean. I have seen bits and pieces through MH370 documentaries, but it would be interesting to see what has been done with the ocean floor data that they have gathered through the searching of the plane.
Commenting on this just to give it more attention
I do believe that the employees of ALfirst need to go back to school!
@Victoria Look at David Pirtle's comment.
Why?
Scientist: Let's make a map of the ocean in order to get a better understanding of the earth Scientist Later: I don't like the scientific understanding that I am obtaining from this map therefore it is all girl talk
There's this whole thing about peer review and even double blind studies to fight confirmation bias or poor science. The irony that scientists themselves are a part of the reason why prevention/ or error correction measures have to be used.
@Parker Ripley Scientists: "If A happens, then 90% of the time it's because of B." You: "Ha! So you're saying C doesn't exist?!" Scientists: "Our heads hurt enough from trying to understand the world, without face-palming when confronted with your idiocy." Please either start thinking or stop typing....
@Michael Tan My guess is that if it a man had suggested that there was a rift down there, the response wouldn't have been, "that's just boy talk."
@Michael Tan because of course misogyny doesn't exist... at all.
@Michael Tan This. Though calling it girl talk was still pretty mean.
It would be very interesting to see how the ocean would move etc if it DID have a flat bottom
It would eventually become pretty much the same as now due to the fact that continents slam into each other, pull apart, etc. Ofc, it would take millions or even billions of years, but it would eventually happen.
Hank looked so Uncomfortable and kind of disbelieving when quoting that "girl talk" diss
I like how he kind of procrastinated saying it, as if that line of the script would just go away and he wouldn't have to say it.
@Mendicant Bias It wasn't about Hank nor the video itself. Just being a woman with an idea can be a challenge in everyday life.
@huldu You literally just watched a video of a man disavowing that diss...
You'd be shocked how often that happen even to this day. Men never change.
she was alive while i was alive, that is wild to me. our advances in the last century are pretty mental.
