2023.05.19- Dr Fiona Clubb- Tectonic and climatic controls on Himalayan sediment storage
Himalayan rivers transport approximately 103 Mt of sediment annually from their source in the steep topography of the High Himalaya to ocean basins. However, the journey from source to sink is not necessarily a smooth one: on the way, sediment can become trapped in montane storage systems, such as river valleys or floodplains. While sediment is stored in valleys, signals of climate change and erosional patterns that we may wish to read from the final sedimentary record can be modified or even destroyed. Despite a critical need to understand the spatial distribution, volume and longevity of these valley fills, controls on Himalayan valley location and geometry are unknown, and estimates of sediment volumes are based on never-tested assumptions of valley widening processes. This is partly due to a lack of reproducible, automated valley extraction methods that allow continuous measurements of valley-floor geometry at orogenic scales.
We present a new method of automatically detecting valley floors and measuring their width from digital topography. This results in continuous measurement of valley-floor width at every pixel along the valley, allowing us to detect signatures of lateral erosion through entire river networks. We then apply this method to extract 1,644,215 valley-floor width measurements across the Himalayan orogen. We use random forest regression to estimate the importance of potential controlling variables on valley geometry, and find that channel steepness, a proxy for rock uplift, is a first-order control on valley-floor width. We also analyse a novel dataset of 1,797 exhumation rates and find that valley-floor width decreases as exhumation rate increases. We therefore suggest that valley-floor width is adjusted to long-term tectonic exhumation rather than being controlled by water discharge or bedrock erodibility, and that valley widening predominantly results from sediment deposition along low-gradient valley floors, controlled by the ratio of sediment to water discharge.

Earth's surface shows many features we can only understand through their connection with processes in the Earth's interior.

Because Earth's interior is largely inaccessible to direct observations, it remains a fundamental challenge to infer its complex dynamics and to explain how it shapes our planet...
2022.05.26- Dr. Bailey Lathrop: How do normal faults grow?
มุมมอง 213ปีที่แล้ว
Continental extension is accommodated by normal faults, and fault growth is achieved by increases in displacement (D) and length (L). Before 3D seismic data became widely used, it was assumed that faults maintain a constant D/L ratio from initiation to cessation, growing steadily via sympathetic increases in displacement and length. Since the advent of 3D geophysical seismic data, it has been s...

Great Job💁♂💁♂
Very nice and informative. Thank you
Wonderful topic, bad audio.
Interesting video. Paleoclimateology is so much more relevant than one would have thought, and geomorphology is maybe the most interesting subject ever.
Level 1 is a computer channel this is not about computers
I saw a geologist talk a while back about the Deccan traps possibly being related to the dinosaur extinction but I haven’t been able to find it lately. Basically he said the meteor itself probably wasn’t big enough to cause such an extinction and life above Colorado would still be alive. The deccan traps could have just made it too hot and dusty for life to survive and acidified the oceans. We have no problem attributing the previous major extinction to the Siberian traps, but for some reason we have been only focused on the meteor impact because of the iridium layer. I actually get needlessly annoyed now whenever I hear “the meteor that killed the dinosaurs” in so many different documentaries with no mention of the Deccan traps lol.
Nice demonstration! I'm preparing for a SedStrat exam and this video was very refreshing!
climate change is bullshit....
Pressure and annoyance that's how faults grow! LoL
Beautiful I'm on the east coast of Australia.
would be nice to see a model of it in 3d and be able to manipulate things in a simulation,, i imagine when a slab eventually breaks away it causes an extinction event, Imagine all these heavy slabs all being stressed while they get pushed into the depths, there is going to be a point where it can't bend or subduct any further and pop, break away happens, causing a tidal wave in the mantle as the slab snaps. This flow of molten rock and pressure is going to knock away more slabs, causing more volcanoes to go. It would explain how there are regular patterns to these supervolcanic events, when one goes they all seem to go.
I suppose there's no separate entry for MSc in this course, is there?
When we look at the many horizontal layers that we find everywhere on our planet, we clearly see the effect of a repeating cataclysm. These disasters are mentioned in ancient books like the Mahabharata of India and the Popol Vuh of the Mayans and others. They tell us about a cycle of seven disasters. Certainly, regularly recurring global disasters cannot be caused by asteroid impacts or volcanic eruptions. The only possible cause is another celestial body, a planet, orbiting our sun in an eccentric orbit. Then it is close to the sun for a short period and after the crossing at a very high speed it disappears into the universe for a long time. Planet 9 exists, but it seems invisible. These disasters cause a huge tidal wave of seawater that washes over land "above the highest mountains." At the end it covers the earth with a layer of wet mud, a mixture of sand, clay, lime, fossils of marine and terrestrial animals, gravel and meteorites. That mud layer hardens and becomes a new horizontal layer on top of many others. The disasters also create a cycle of civilizations. To learn much more about planet 9, the recurring flood cycle and its timeline, the re-creation of civilizations and ancient high technology, read the e-book: "Planet 9 = Nibiru". It can be read on any computer, tablet or smartphone. Search: invisible nibiru 9
Really usefull since I'll be a Geologist. Thank you! The only part I didn't get is this crossbeds. Have to search...
Sort of like what could be causing the horn of Africa to split
Its all fun and games until a flood basalt eruption happens and covers a whole country.
Was probably interesting, but I couldn’t understand what you were saying

Bit of an abrupt end, but interesting.
Excellent program. Thank you.
Very interesting thank you.
Your map doesn't show the Canadian Shield.
Is that from a basalt eruption?
He said hot pockets...I love those damn things. They taste awesome. Great video!
Astroid impacts is what causes these eruptions. The flood basalt eruption occurs on the opposite of earth from the astroid impact.
why do uyuber's have to stick their faces on the videos?
You have serious cognitive dissonance going on there like you mind is fragmented and the different parts are totally oblivious to one another, thanks God for morons without whom some people would not have an audience or a job....
Sorry I lost you with the New World Order climate garbage.....so you know about volcanoes and climate cycles and still believe in absolute garbage???
Wait, you believe that flood basalt eruptions can effect the global climate? How do they know the climate was any different when these eruptions occurred?
@@Skibbityboo0580 That's the problem with garbage believers, they have issues with finding unbiased science papers and reading them, not listening to bought and paid for political BS, all the evidence is there, you just have to find it and read it....simple....
@@nicolasnicolas3889 So you really think that these large scale eruptions changed the whole climate way back in the day?
@@Skibbityboo0580 I understand what you are saying that who know's what the atmosphere was like back in the day, but regardless of this is must have changed the climate, whatever the atmos was like....apparently there was a time then the entire reality was ice for many millions of years so, you know, but if the atmos was similar to today then it would have been really bad.....
@@nicolasnicolas3889 Wow that's crazy! I didn't think a volcano could do that! I am going to research how they know what the atmosphere was like back then. Because how would they know if it would change the climate like that? That must mean that the climate is heating up because there is some underwater basalt eruption going on.
great lecture and great video. also itz fantastic where you put your own live person at the small corner instead of a big dead center--as other, self-worshipping people do. btw/ thr first flood basalt was over FOUR continents: Europe, N. America, Africa and S. American. you describe it, but you say "3 continents" by including Europe with Africa. pls dont.
confused.. lecture says the siberian traps are the largest volcanic event in the last 500 million years, but you also say the CAMP occurred 200 million years ago but that it is the largest flood basalt ever..?
A welcome breath of fresh air from the entertainment-centric content proliferate across TH-cam. Thank you!
The Deccan traps where most likely created for the Chicxulub impact. Because the syberian traps where created by the the Wilkes Land impact.
Impact induced LIPs is appealing hypothesis. Sadly for now, not enough evidence. For example: deccan traps eruotion started well before impact. As for Wilkes land is still not confirmed as impact site. We're unable to confirm its age also, for now. It's appealing, but not more. For me: I would be very excited if impact induced LIPs were a real deal. That would be astonishing.
@@fijagr what is lip?
@@temosofthecommunistrepubli2637 Large Igneous Province, Deccan Traps for example. If You like this topic, there are two good videos on 'Facts in motion' channel. One for flood basalts, one for hotspots.
@@fijagr interesting . Thanks
Okay this is so weird - I came to this video off of another volcano vid because I thought "hmmm, Deccan Traps is interesting." See the narrator and think "that looks like a guy I met at swing dancing." Check the name, and either you both have the same name, same face and same voice, or you are the same person. Hi!
P.S. Great lecture! I'm gonna get my volcano nerd on and watch some more! :)
It is not helping that you make yourself visible in the lower corner of the screen. It is just annoying (to me because it is vain) and it blocks some interesting information at times. So, unless you can't resist showing yourself without any obvious need to do that (like trump), your lecture would be even more interesting to me if you disappear when talking. Thanks.
Keep uploading!! All the best and good luck with growing your channel! Did you ever check promosm?! You could use it to promote your videos.
I say...bloody good stuff this.
Fascinating topic. Thx very much, job well done. My dear ole Ma used meander too. lol. She was and is an angel.
West coast California. Today. Basaltic flood eruption
Would that be around the Long Valley Caldera volcano area by Mono Lake... do you think?
This is what is happening now in north America.
This is a fantastic overview. Despite reading plenty about historic flood basalts, my mind just couldn’t wrap around the scale and mechanisms behind it. Your imagery and concise explanation helped so much!
I thought the Bushveld complex had been determined to be caused by an ancient very large asteroid impact.....
Its weird but flood basalts and magmatic provinces and any talk of massive volcanic eruption amd I am always reminded of the Land Before Time.
Hi, I'm from Nigeria and I'm interested in pursuing a master's degree program. Any scholarship for international students?
Hi Gabriel, Yes there are funding opportunities available.

Here is an example link to our Sustainable water environments which has links to funding opportunities on the page www.gla.ac.uk/postgraduate/taught/sustainablewaterenvironments/
Hi Gabby. Where you able to apply for any?
Hello from New Zealand 🌱🌏💚
your mike is causing flood basalt in my ears.
So interesting- loved visiting the Ellora caves carved out of this lava
are you sure the current age is not better classified as the social media era?
The term "trap" has been used in geology since 1785-1795 for such rock formations. It is derived from the Swedish word for stairs ("trappa") and refers to the step-like hills forming the landscape of the region.[4] from wiki
Doesn’t it happen under water
No
i wonder if the basalt plumes start a one specific spot on the core. ?
I live in SE Oregon where flood basalts created our landscape. Great lecture. Thank you.
I've driven across the Columbia River Basalt portion that is in Washington and along the Columbia River. It is awesome.
