Marie Tharp: Uncovering the Secrets of the Ocean Floor - with Helen Czerski

[@TheRoyalInstitution]

Chinese, Portuguese and Spanish, these are the three languages that this video has been translated into by our talented and generous KZbin friends!

[@ShubhamBhushanCC]

A salute to the Heroine of Geology.

[@cosmicwarriorx1]

great video... thank you for bringing her story to public.

[@Malfunct1onM1ke]

I loved the video, allthough the drawings made me a bit dizzy, but that is just me. Well done, Folks!

[@olfmombach260]

Explained in a beautiful way.

[@markcox5385]

Excellent video about stuff I've never heard about. Would love to see more in this style. Well done to all involved. 😀

[@RichardEricCollins]

Great video had not heard of Marie Tharp. Nice to hear Helen again I thought it was her narrating. :)

[@martinsapsitis4292]

Awesome Marie!

[@vazak11]

Why was this not taught to me in school!?!?

[@rameshdevasi6720]

and marie literally means star of the sea.

[@kyle4563]

fitting name

". . . A pattern of scars that spanned the Earth's oceans - permanent wounds torn into existence through the process of continental drift." That sounds so poetic and beautiful. However, we should also consider that the drift didn't CAUSE the "scars", perhaps the energy lines where the scars appear are DRIVING the continental drift.

[@nightjarflying]

Nonsense - you'll mention UFOs, ley lines & the Bermuda triangle next perhaps? What "energy lines" are you referring to? There is a field of science called Plate Tectonics from which we understand that continental drift is the movement of continental plates NOT driven by some mysterious "energy lines" along the edges of the plates, but by the distinct tectonic plates being 'pushed' around on the fluid-like asthenosphere below them. The driving mechanism behind this is dissipation of heat from the mantle below. "Energy lines" LOL

[@ratboygenius]

nightjarflying Perhaps. But why are the boundaries of the plates WHERE they are? Accident? How else can you describe the energetic forces pushing the plates apart so forcefully along the oceanic rifts so that the ocean floors near the rifts are much younger than the ocean floors near the continental shelves? Just because plate tectonics has a theory of what's happening, it doesn't mean it has any idea of WHY.

[@nightjarflying]

No mystery & no "energy lines"! There is also no gap in knowledge that requires a "WHY?" - yes there are competing theories as to the details, but no need for your "energy lines" [which you've failed to explain - I asked you what you meant by that phrase. The boundaries of the plates are determined by where there are random weaknesses in the imperfect crust which varies in composition & thickness - just like the breaking of ice into pieces on a lake as spring arrives. Repeat: this is not a mystery. The ocean floors are obviously younger near a spreading rift & oldest at an area of subduction so your point makes no sense. What IS your point anyway? The fact that seas & oceans form at many [but not all] the locations of divergent plates is AFTER the fact of plate tectonics. Thus we have the developing East African Rift [EAR] as a prime example which will likely put a sea [& then an ocean] right down through Africa in around 10,000,000 years - it is supposed that rift is there because of upwelling of flood basalts & other deep processes.

Loved this! Marie Tharp appeared in the BBC Earth Story from the 80s (or was it 90s?) It is a fabulous series including the development of the theory (then) of continental drift. Narrated by biologist Aubrey Manning, rocks never sounded so interesting! Where David Attenborough's Life series told us about the evolution of life on earth, Earth Story provides the geological angle.

[@Nehmo]

There is also the lesser-known Continental Drip theory. The continents were formed by pouring liquid continent over the globe, as in a Sherwin-Williams Paint logo goo.gl/afpPWH . If you will notice, virtually all peninsulas point south.

[@Skapete]

Beautiful stuff!

[@mitzvahgolem8366]

Bravo...Rosalin Franklin and Lisa Mietner...

[@wndmier90]

hermoso contenido 😊

[@isabellchristofferson7042]

She's really inspiring

[@anon0815de]

Very good video. The name is Wegener, not Wengener.

[@SECONDQUEST]

great video

[@fzhhns1237]

You are my idol as geologist 😘

[@iankelsall25]

the irony of men doing hard science, whilst saying it's bad luck to bring a woman on a ship...

[@locouk]

I wonder where the idea of a woman onboard a ship brought bad luck came from?

[@LiamE69]

Men fighting over them.

[@gravelbar]

Very old nautical concept.

[@bumpkin53]

So, Tharp didn't have enough evidence and needed Howard Foster's research to prove her theory. Sounds like Howard Foster needs more credit here.

[@raphaelreichmannrolim25]

Nice!

[@lskutches]

Here is a 2006 NYT video about her www.nytimes.com/video/magazine/1194817114284/marie-tharp-b-1920.html Such an inspiration!

[@brandon-vi8cl]

great vid

From Twitter

[@Siriuslyyy]

great topic and narration, but the video had too much vibration in it. please don't do that ever again, it was distressing to the eye.

[@OrangeFluffyCat]

Sumbrela Sure, maybe not every again, just sometimes again.

[@Ngamotu83]

My admiration for Marie Tharp has skyrocketed up from nothing, while my respect for Jacques Cousteau has shrunk.

[@Wayfarer-Sailing]

Wegener.

Girl talk?

[@irek1394]

Barium ?

[@BariumCobaltNitrog3n]

When she presented her findings to her boss, he dismissed it as "girl talk" because that's what girls talk about. Apparently

[@irek1394]

Becouse people thought women are like kids and often talk nonsense

[@BariumCobaltNitrog3n]

well, they are hard to understand sometimes

[@BariumCobaltNitrog3n]

Most women have boobs. I would disagree that most are stupid, and so does the data. "In the last 100 years the IQ scores of both men and women have risen, but women's have risen faster." www.telegraph.co.uk/education/educationnews/9401241/IQ-tests-women-score-higher-than-men.html

[@pineapplehazeclub]

I love the video till you start speaking about tectonic plates movements.

[@googolplexbyte]

[@graphomanuk8544]

Love the statement "turn the tide". She's wrong though.

[@newdrew2744]

Continental drift is false. The ocean map which this video (never showed!) debunks continental drift and Pangae! The real secret of the Ocean Floor Map is, it shows that all continents where connected as a smaller sphere! Look at the map!

[@primemagi]

very good video, but practice of Dogma in science has become epidemic level specially in cosmology and structure of matter. RI is one of the main institution which retain the current ignorant models and understandings. check my 2015 email to RI. MG1

[@3enjoy3]

mg1s Do you have a background in science? Genuine question. I see both from here and your own channel that you make bold statements reproaching scientists and conventional science but where does your own knowledge come from?

[@primemagi]

ask British and American secret services. they have been watching me past 40 years.

[@BariumCobaltNitrog3n]

Aren't you the clever one.

[@metapyziks]

Do you need a hug mg1s

[@LiamE69]

No, he needs to take his meds.
