I'd pay so much money to hear you give a lesson on paleontolgy. Whenever you write about you seem so formal and passionate ✨️
this is sooooo sweet but i guarantee you don’t want this bc the first lesson would be on terminology and the geologic timeline, some of the most boring but fundamental shit 😭😭
or, hear me out—that but my feeder is stuffing me more and more. the lesson keeps getting interrupted by sips of weight gain shake and many belly rubs
#‘boring’ is relative btw#i hate how and why words work but i love the geologic timeline#i love how life has developed throughout all of it#and i love how a deeper understanding of that span of time truly changes your worldview#i see things as their path through time#idk if that makes sense but i see an oak tree and am just happy to know they’ve been around for like 40 million years#and i LOVE knowing what formations and areas fossils come from#one goal of mine is to have a piece of live oak fossil wood from the willis formation of southeast texas#it’d take some work to identify but god. i am willing#talk#ask

i love how hgsn has just become Yoshiki’s independent research project with the occasional ghost roadblock
#Our next enemy will be Yoshiki’s pencil breaking while he’s in the middle of a sentence!#hikaru ga shinda natsu#the summer hikaru died#hgsn#my hgsn shit#I’ll need about 5 maps of varying styles (political; topographical; geologic; physical; and maybe a resource map)#And 7 more flow charts and a comprehensive time line before I truly understand what’s going on#How many mountains are there again

gahhhh argh I'm a history student for a reason man, I'm working ahead and reading up on pre modern city structure and it's so much more interesting and easy to understand,,,,, the author is giving me new databases to explore,,,,,, ohhhhh my god I cannot wait to be done with the geography
#twine speaks#esmp mapping project#do you think i need a separate tag for yelling about this thing#maybe i can just organize the coherent explanation parts into a masterpost at some point???#anon who asked about the rivers im so sorry its been forever i know but hydrology makes my head hurt#everything begins to blend into soektbing flow rate something cubic feet/second something something seasonal variation so fast#you have no idea how much time ive spent squinting at us geological survey data and trying to understand how big of a river#can be in different places

who wants to go to the grand canyon w/ me so i can gush abt all the rocks 🥺🥺 i’ll recite the wikipedia page for it SO well you don’t even understand
#like FOR INSTANCE did u know they're striped bc they're MADE OF DIFFERENT THINGS?#that's just a little taste of the geological wisdom you'd get#no but actually i want to go so so bad i've studied the grand canyons composition but i've never been and i WANNA SEE IT!!!!!!#IT'S GOT ROCKS MAN!!!! GEOLOGICAL FEATURES!!!!! EARTH HISTORY!!!! ALL THE GOOD STUFF#sometimes i think i want a gf just so i have someone i can do my dream roadtrip of visiting every national park in the us#i wanna see them :( theyre so cool i love them all they have ROCKS do you UNDERSTAND#ROCKS!!!!!!#the moon speaks#ohhh geology major i'll get you someday just you wait and see!!!

My church wasn't quite as hardcore on the anti-science stuff as many, but I still absorbed a lot of ideas I just never thought too hard about. Like, my mom definitely told me that all the 600 and 900-year old people in the Bible were because "people just lived longer back then" and I just... didn't really question it. I was a very scientifically minded child, but I just didn't ever think about the logic of it! It wasn't until I was in my late 20s that someone mentioned it and I went "... hang on, that is an absolutely bonkers idea, of course people can't live for centuries??"
I knew that as a kid, too... but I never connected the dots.
y’all I CANNOT
#Christianity#honestly geologic time is so hard to understand as is#65M years ago and 150M years ago feels like the same amount of time#it's not a real number#let alone BILLIONS#I kinda get why people can't grasp evolution

I know I'm asexual and I'm within a reasonable degree of certainty that I'm aromantic but I still feel like I have a pretty firm grasp on what is "hot" and what is "sexy" without those particular areas of attraction. Allow me to elaborate
An aesthetically or conceptually inspiring trait is "hot"
An aesthetically or conceptually inspiring ability is "sexy"
"Hot" is the appreciation for the theatre
"Sexy" is the appreciation for the zeitgeist
Something that is "sexy" is always "hot", but something that is "hot" is not always "sexy"
Things that are "hot", imo:
Antique wootz steel blades
A black 2020 Chevrolet Camaro
Eyeliner
Tongue piercings
Charlize Theron's voice
Things that are "sexy", possibly also "hot":
Martial arts
Pole dancing
Those video compilations of manual labour workers doing things nobody even thinks about super quick and efficiently
People who are really smart who study really specific stuff like geological chalk formations and shit
Things that are definitely "hot" and "sexy":
Being in a hardware store
A perfectly executed backflip
Good art that hits different
The sensation of drinking very cold water when you're really gross and hot and tired and it's like oooohhhhohohoho FUCK yeah
And finally, things that I'm reasonably sure are probably either "hot" or "sexy" that I still don't fully understand but am willing to take the L on:
Getting a massage (?)
Weiners
Football players, probably
Perfume commercials

Earth's Icy Past: Understanding the History of Ice Ages | Proterozoic Snowball Earth
Understanding the History of Ice Ages
Earth’s Ice Ages are periods in the planet’s history characterized by a significant drop in global temperatures, leading to the expansion of ice sheets and glaciers. These periods can last for thousands or even millions of years, and have occurred periodically throughout the planet’s history. The study of Earth’s Ice Ages provides valuable insights into the causes and consequences of climate…

Literally every conversation with a colleague/peer in the academic field I'm in (anthropology, with a focus on human prehistory and human evolution) upon them learning I'm an observant religious Jew goes like this:
Person: "Sorry if this is a personal question, but how do you.... y'know......deal with it?"
Me: "Deal with what?"
Person: "Y'know...... y'know......your religion......"
Me: "Meaning?"
Person: "Well, um, how old do you believe the earth is?"
Me: "I follow the geological consensus, which is approximately 4.5 Billion years"
Person: "But......but.....your Bible says that it's 6,000 years old....."
Me: "Technically 5,783 years, so you're wrong there, haha"
Person: "Okay but how do you....how do you reconcile that with science?"
Me: "I don't need to reconcile it. They're not in opposition."
Person: "??"
Me: "The plain text in the Tanakh states that it has been 5,783 years since the creation of Adam, and consequently the world. Judaism has never been about taking the text in the Tanakh plainly, there's always deeper meanings. Who's to say that the 5,783 years aren't just the years since a couple named Adam and Eve met and copulated, triggering the begining of the lineage of Abraham, Moses, and the entire Jewish lineage, and that the six days of creation aren't six phases which are actually pretty in-line with our understanding of evolution?"
Person: "But.....some people believe that it's literally been 5,783 years since the earth was literally created!"
Me: "Okay..... that's what they believe. I don't see how it should bother me, especially considering we're in the field of anthropology where we try to study other patterns of belief, not cast judgement upon them."
Person: "But other Jews believe that!!!"
Me: "Again.....why should that affect my religious and academic senses of self? Judaism has never been a monolith of belief, anyway."
Person: "But-"
#for real it's so tiring#i literally could not give two shits what other people believe#and considering anthropology's history with mocking indigenous creation stories quite frankly you people should be doing better#anthropology#religion#judaism#personal

Yay for spodumene! Spodumene varieties are lesser known in the gem trade than many of the more famous gem species (I admit I'd never seen it before studying my diploma) and kunzite and hiddenite are probably the most desirable.
(@theproblemwithstardust I know you probably know more about this than me but here's the breakdown for anyone who is interested...) Oh but also below a keep-reading because I also rambled ^^;
pure spodumene without any impurities is clear Many gemstones would be colourless if they were completely chemically pure. Their colour comes from trace amounts of other chemical elements which are not intrinsic to the chemical crystal structure of the mineral itself - these are called allochromatic or 'other-coloured' gems!
For example, pure corundum (aluminium oxide) is colourless (we'd call it white sapphire! If it contains traces of iron and titanium this colours it blue, and we call it sapphire. If it has impurities of chromium it is coloured red, and we call it ruby!
Gemstones where the colour is caused by an element intrinsic to the crystal structure are called idiochromatic or 'self-coloured'. Examples include peridot (magnesium iron silicate) and pyrope-almandine garnet (iron aluminium silicate)
pink/purple gem varieties [of spodumene] are called kunzite and the color is caused by trace amounts of Mn Manganese as a colouring element in gemstones often produces a pink to orange colour palette depending on the surrounding crystal environment. It causes the pink of spodumene var. kunzite and beryl var. morganite as an impurity (allochromatic gems), and the orange of spessartine garnet and pink of rhodonite and rhodochrosite as an intrinsic chemical element (idiochromatic gems)
the color is very prone to fading in uv light A great tip for any pink or light purple stones is to keep them away from strong light! Their colour can fade from prolonged exposure to ultraviolet radiation, and you wouldn't want to spoil your beautiful gem collection - so tidy your jewellery away nicely and maybe stop keeping your rose quartz crystals on the windowsill in full sun :')
Fun fact I did my own experiment with zircon based on a paper I'd read about reversing the colour degredation caused by UV exposure. I was so excited I forgot to take before and after photos! The great news is (in zircon at least) you can reverse the colour change by exposing the stone to incandescent light (which is typically accompanied by infra-red radiation - ie/ the kind of light bulb that emits heat!) But I'm getting distracted from spodumene...
The dark green variety is hiddenite, NOT kunzite like it is labeled here and the color is due to trace amounts of Cr and possibly V My memory hack for learning this gem variety was that hiddensite is like Hiddleston like Tom Hiddleston who wore green as Loki in the Marvel films :P So yes the chromium-coloured green variety of spodumene is called hiddenite!
Many lesser known gem colour varieties get referred to as 'colour famous-cousin' for ease of explanation - it's not gemmologically correct but it often happens particularly when it comes to trying to sell these things! Lots of people wouldn't know prasiolite, but they can imagine what you mean when you say 'green amethyst'.
That said, there are times it is correct to do this! Sapphire occurs in every colour except red (because if it's red, we call it ruby), but any other colour is referred to as 'colour sapphire'. So it is correct to say pink sapphire, yellow sapphire, purple sapphire! If you just say 'sapphire' we assume you mean blue :)
the pale green/yellow gem variety of spodumene [is] called triphane Oh exciting! I didn't know this! ^_^
Not spod related but we also learned in mineralogy that bixbite is an outdated term since it’s so close to bixbyite. we just call it ‘red beryl’ but I’m not sure what it is like in the gem world!) The proper way to refer to it would be beryl var. red beryl, but if you said bixbite we'd still know what you meant! :) This is also a gem which would be misnomered as 'red emerald'...
Naturally occuring red beryl is very rare, and typically occurs in small sizes not suitable for faceting as gemstones. That said, these things can be created synthetically and synthetic hydrothemal red beryl is another stone which shows FAB orange/pink pleochroism!
ps. I think a lot of the pictures in the original post are colour enhanced, it's a fun guide but maybe go speak to your friendly neighbourhood gemmologist if you want to know if they're actually representing the colour correctly!

#i feel like i'm going to let you down now by confessing that i am not a lapidary#but i am a qualified gemmologist#i understand the theory of gem cutting considerations such as clevage planes - maximum yield - correct orientations for optical effects#but i don't actually cut stones so i can't answer your emerald question other than 'carefully'#i can tell you all about their stabilising treatments though?#my favourite gemstone is sapphire#because blue is my favourite colour#but my favourite gem In My Collection is moldavite#moldavite is the transparent to translucent green variety of natural glass tektites#which are formed when meteoric impacts fling superheated molten rock into the air#which cools and solidifies to glass#my moldavite has the most gorgeous intricate air bubbles#swirly twisty corkscrew shapes#i love it#i love just looking at it under 10x loupe#and as a special treat#putting it under the microscope for up to 60x magnification#geologically interesting#gemmology#infodump

I was struck by how the entity’s growths formed in a spiral pattern, almost like a double helix you’d find in a strand of DNA. Oil is made from the fossilized remains of ancient plants and animals. It’s a sort of geological memory, just like how DNA is an evolutionary memory that allows the body to build and rebuild itself. And the primary thing that it affects when it touches people is their memories, whether random flashes of nostalgic images or deeply personally significant memories.
Going off of the DNA analogy…I don’t think the entity held any malice towards the crew. I don’t think it could hold malice to begin with, or goodwill, or any other more complex emotion. DNA is a chain of chemicals, and we have no conscious control over its transcription. The only thing it “wants,” as far as a chain of chemicals wants something, is to stay alive and to replicate itself. Its connection to oil also makes it feel like whatever dead, fossilized organic matter was trapped beneath the surface of the earth very mindlessly trying to return to life. The assimilated crewmates looked like cancerous lumps, growing out of control and endlessly dividing, not out of ill will, but because the cellular mechanism for growth had broken and was replicating out of control, only writ large, across the body of a whole person. The growths, like DNA writ large, a strand of chemicals trying to reassemble itself from whatever chemical matter from the rig and the crew it could use.
There’s a strange “humanity” to the entity, too, though in a very primal, instinctual sort of way. It wanted to be one with the rig and everyone on it, and it kept dredging up memories where Caz and the others felt especially close to their loved ones, even if they weren’t always happy ones. Caz, too, wanted to be one with his family again, but had that dream dashed by a selfish, individualist action. He wanted to keep his fellow crewmates together, and was increasingly devastated as assimilation or death cut them off from each other. The ending was beautiful, and felt like a barely comprehensible sort of kindness despite everything that had led up to it. For a moment, it felt like Caz reached an understanding with the force that had consumed him and that he in turn had destroyed, at least enough to forgive it and let go. In exchange, he got to relive the last time he and his wife were truly together, the morning he left for the rig. And then, over the empty ocean, we hear Suze’s tearful plea to Caz to come home, to reconnect with her, to be part of their family again. The letter felt like a summation of what Suze, Caz, and the entity itself wanted—to return home, to connect with others, to feel “whole” again.

The Report
Winter: General Ironwood, I wish to make a report about my joint mission with, Jaune Arc on a, C Class seek, and destroy mission.
Ironwood: Ahh good. I was going to ask you to report on that mission. You rarely take any missions from the quest board since becoming my second. Any missions you do take, are missions I sanctioned you to take, along with the rest of your specialist members. So, tell me, Specialist Schnee, why did you decided to take on this mission, and with Jaune Arc at that?
Winter: At once, Sir.
Winter: I was made aware of the mission particulars whilst I was playing a game of chess with, Mr. Arc. He informed me that he had never heard of the target before reading the mission request. Upon doing research about the target, a C Class Grimm threat called a, Karniviar, and more research about the, Grimm's last know location, he deemed this quest to be a, B, or potential A Class threat.
Ironwood: He deemed it to be a potential, A Class threat? What made him think so?
Winter: Understanding the potential threat of a, Karniciar alone more than grants it the ranking of a, C to low, B Class threat. It's bone platting requires high caliber AP rounds to pierce. It's claws posse the capabilities to tear through reinforced fencing with ease. It possess a bight force of an estimated 20,000 psi, making it capable of biting a, Knight in two with relative ease. All the while it's tail spike posses the potential to pierce through the armour platting of one of our, Paladins.
Ironwood: Fascinating... what level of it's evolution is this, Grimm categorized as?
Winter: Unknown, Sir. I did my own research before joining, Mr. Arc on this mission, and from what meager reports there are, I lean fiund myself agreeing that this is an, egg based, Grimm.
Ironwood: Egg?
Winter: Yes, the first stage of this, Grimm begins in an egg stage where it remains underground until it matures, and hatches into a fully formed, Karniviar. I would estimate this this new born stage to be at least in the, Gamma Classification.
Ironwood: Gamma? If it was already like this, I would hate to see it in the, Beta Class of it's evolutionary development, let alone in it's, Alpha form. So, this is why, Mr. Arc saw it as a potential, A Class threat.
Winter: Negative, Sir.
Ironwood: Beg pardon?
Winter: Mr. Arc did not see the, Karniviar as a possible, A Class threat for those possibilities, Sir. He saw it as a possible, A Class threat due to it's geological location, and it's potential harm it could inflict upon, Atlas, and Mantle.
Ironwood: 'Because of where it was located, and it's potential harm it could inflict to the people of, Atlas, and Mantle?' I must say you have me most intrigued, Specialist Schnee. Please, continue.
Winter: Thank you, Sir. During, Mr. Arc's research he found out that the, Karniviar was located near a fishing town called, Breakers Peak. This town itself provides sixty percent of, Atlas, and Mantles raw supply of fish.
Ironwood: Sixty percent of, Mantle, and Atlas fish supply? Ahh I see... He classified it as a potential, A Class threat because if it attacked this fishing town it would disrupt the amount of food entering, Atlas, and Mantle, didn't he.
Winter: Partly, Sir. Mr. Arc theorized that if this, Grimm attacked, Breakers Peak, and even if it only managed to reduced the towns fishing capabilities by thirty percent, the consequences could be quite dire. If the price of fish goes up, the price of any food produced items with fish goes up as well. Resulting in an domino effect where the rise in prince of one item leads to the rise of price in another. And, if food prices continue to rise people would start to get worried, and as the more people get worried...
Ironwood: The Grimm become more active. And thus, the result of leaving this, Grimm alive leads to potential devastation to, Atlas, and Mantle without it even having to attack us directly.
Winter: Mr. Arc's thoughts came to the same conclusion as well, Sir.
Ironwood: No wonder he saw it as a potential, A Class threat... His thought process taking into the account not just the, Grimm itself, but where it was seen, and the possible threats it could have in that given area. Hmmm... I think we need to adopt such a train of thought when assigning threat levels to missions.
Winter: My thoughts exactly, General. I have already started a rudimentary outline of a possible new way of classifying , Grimm threats based upon. Mr. Arc's thought process.
Ironwood: Very good. Hand that to me for my review once it is completed.
Winter: Of course, Sir.
Ironwood: So was this the reason why you accompanied, Mr. Arc on this mission?
Winter: It was one of three reasons, Sir.
Ironwood: One reason? What were the other reasons?
Winter: When, Mr. Arc told me about this mission, we where playing a game of chess. A game where... he thoroughly defeated me... Effortlessly at the...
Ironwood: Effortlessly? For you to say that is quite the complement, if I am not mistaken, you are considered a grandmaster at chess.
Winter: I am considered a grandmaster at chess, but after, Mr. Arc thoroughly defeated me, I feel like a novice at chess once again.
Ironwood: What did he do?
Winter: I don't know how he did it precisely, but to summarize: Psychological warfare.
Ironwood: Psychological warfare? Hmmm... I didn't take, Mr. Arc as one who would apply such tactics in a fight. How did he do it?
Winter: I was focusing on the fact that, Mr. Arc hadn't moved his queen, thinking that his plan was to move his other pieces into the perfect position so he could suddenly spring a trap, deploy his queen, and go for the kill. But, in actuality his plan was to make me think that he had some sort of grand plan with his queen as the focal point of it. However, Mr. Arc had no intention whatsoever of using his queen, and was instead focusing on getting my other pieces into the perfect position. And, then go for the kill.
Ironwood: His entire strategy was based on the idea that he was going to us his queen, the most valuable piece on the board. When in fact, he had no intention of using his queen from the begining?
Winter: Correct, in fact I was so focused on his queen I never realized that he in fact, never physically touched his queen to begin with. It was because of this unexpected strategy he implemented, I was curious to see how he planned to deal with the a beast such as the, Karniviar all on his own. So, I asked to accompany him.
Ironwood: I see, how did he deal with the, Karniviar.
Winter: When we arrived at the town he asked the locals where the, Karniviar was last seen, Jaune then went to the area to explore it. When we arrived at the area it was last seen, an old abandoned, Dust mine. Jaune spent some time watching the monster from a distance where he finally implemented his plan.
Ironwood: Which was?
Winter: Mr. Arc came closer to the, Karniviar, the beast turned to roar at him, and in that instant the, Karniviar roared, Mr. Arc threw one of his portable shield walls into it's mouth. When it went done the creatures mouth he activated it, and broke the creatures neck from the inside. The creature died within seconds, and started to fade away before it even hit the ground. From start to finish, it only took a minute for, Mr. Arc to defeat a C Class threat.
Ironwood: Seriously?
Winter: Yes, I have video of the event to prove it.
Ironwood: Show me.
Ironwood: ...
Ironwood: Impressive... that was most impressive.
Winter: I assumed, Mr. Arc would stabbing the creature between it's armour plates, but as, Mr. Arc said: 'There are plenty of chinks in its armour to exploit.'
Ironwood: I would have attacked the creature between the armour plating, or trying to break the platting. I must confess, I wouldn't have thought about going down it's throat. I can see why you decided to join, Mr. Arc on this mission. This was quite an informative mission you decided to take on.
Winter: That... That wasn't entirely why I joined him on this mission, Sir...
Ironwood: Ahh, the third reason why you joined him. Tell me, what was this third reason?
Winter: I am... I am worried about, Mr... I am worried about, Jaune's mental stability, Sir...
Ironwood: His mental stability?
Winter: As a result of his social isolation because of his peers. Jaune has developed a habit of talking to himself; He denies that this has been happening of course, but on the few times I have caught him talking to himself, his eyes linger to the side for a bit before denying it.
Winter: I am worried he will harm himself, directly, or indirectly because of this. So, Sir, I request permission to be assigned to any joint missions, Mr. Arc takes. So, I can ensure his mental stability.
Ironwood: ...
Ironwood: Permission granted. Also try, and see if we can get him in for a psychiatric evaluation as well. In fact, put all of, Team RWBY, and the other members of, Team JNPR into this as well. This is standard practice anyway among veteran, Hunters. These kids have been through quite enough as it is.
Winter: Thank you, Sir. I will do so at once.
Ironwood: Oh, and, Specialist Schnee?
Winter: Sir?
Ironwood: My condolences concerning the loss of your father.
Winter: T-Thank you, Sir... It was so sudden, I have no words for this sudden, terrible incident that has happened to my family. It's such a shame that he was taken from us...
Ironwood: ...
Winter: ...
Ironwood: That was a terrible performance, Specialist Schnee.
Winter: Did you honestly expect me to be sad after that monsters death, Sir?
Ironwood: No, not at all. I just thought I should say it, it was polite to offer my condolences for the loss of a family member. I certainly didn't take a celebratory drink at the news of his passing. No, nothing like that happened at all.
Winter: Of course, nothing happened at all.
Ironwood: Well then, is that all, Specialist?
Winter: Yes, Sir.
Ironwood: You're dismissed.
Winter: Sir!

New Mexico Footprints are Oldest Sign of Humans in Americas
Fossil footprints date back to between 21,000 and 23,000 years ago, upending previous theory that humans reached continent later.
New research confirms that fossil human footprints in New Mexico are probably the oldest direct evidence of human presence in the Americas, a finding that upends what many archaeologists thought they knew.
The footprints were discovered at the edge of an ancient lakebed in White Sands national park and date back to between 21,000 and 23,000 years ago, according to research published on Thursday in the journal Science.
The estimated age of the footprints was first reported in Science in 2021, but some researchers raised concerns about the dates. Questions focused on whether seeds of aquatic plants used for the original dating may have absorbed ancient carbon from the lake – which could, in theory, throw off radiocarbon dating by thousands of years.
The new study presents two additional lines of evidence for the older date range. It uses two entirely different materials found at the site, ancient conifer pollen and quartz grains.
The reported age of the footprints challenges the once conventional wisdom that humans did not reach the Americas until a few thousand years before rising sea levels covered the Bering land bridge between Russia and Alaska, perhaps about 15,000 years ago.
“This is a subject that’s always been controversial because it’s so significant – it’s about how we understand the last chapter of the peopling of the world,” said Thomas Urban, an archaeological scientist at Cornell University, who was involved in the 2021 study but not the new one.
Thomas Stafford, an independent archaeological geologist in Albuquerque, New Mexico, who was not involved in the study, said he “was a bit skeptical before” but now is convinced.
The new study isolated about 75,000 grains of pure pollen from the same sedimentary layer that contained the footprints.
“Dating pollen is arduous and nail-biting,” said Kathleen Springer, a research geologist at the US Geological Survey and a co-author of the new paper.
Ancient footprints of any kind can provide archaeologists with a snapshot of a moment in time. While other archeological sites in the Americas point to similar date ranges – including pendants carved from giant ground sloth remains in Brazil – scientists still question whether such materials really indicate human presence.
“White Sands is unique because there’s no question these footprints were left by people, it’s not ambiguous,” said Jennifer Raff, an anthropological geneticist at the University of Kansas, who was not involved in the study.

-Sappho: you are a trans lesbian
-Proust: you post a lot of "slut in theory" memes. you get anxious going to the seven-eleven
-Euclid: you taught yourself to draw a perfect circle. You think about geological formations a lot. You've memorized that Edna St. Vincent Millay poem

The Moon might be a bit of a dark horse when it comes to water. According to a new analysis of mineralogy maps, water and hydroxyl – another molecule made up of hydrogen and oxygen – can be found in multiple locations across all lunar latitudes and terrains, even where the Sun shines down most powerfully. It's a discovery that has multiple implications. It can help us understand the Moon's geological history and ongoing processes, and inform future crewed missions to Earth's satellite.

Volcanic activity on the seafloor creates scattered oases known as hydrothermal vents. These underwater geysers spew superheated water rich in dissolved minerals. When that scalding-hot water comes in contact with frigid deep-ocean water, the minerals crystallize, raining tiny flecks of “ash” to the seafloor. Those mineral deposits build up over time, creating breathtaking spires and “chimneys” that can grow to hundreds of feet tall. Less than 25 percent of the seafloor has been mapped at the same level of detail as the Moon or Mars. MBARI’s mission is to advance marine science and technology to understand our changing ocean—from the surface to the seafloor. For nearly four decades, MBARI has explored the deep ocean, recording thousands of hours of video with our remotely operated vehicles and mapping thousands of kilometers of seafloor using advanced robots. Together, these tools are helping to create a clearer picture of the amazing environments hidden in the ocean’s inky depths. The astonishing communities that live on and around hydrothermal vents have evolved to flourish under extreme temperatures and chemical conditions. The remarkable tubeworms, crabs, clams, and more that thrive here are found nowhere else on Earth. Now, with more companies looking to extract mineral resources from the ocean, it is more important than ever to study the deep sea and the wonders it holds. The maps we create and data we collect can help resource managers make informed decisions about the ocean, its inhabitants, and its resources. Together, we can safeguard these unique biological and geological treasures.
