Ancient Volcanoes of the Mid-South Between 80 and 70 million years ago the South Eastern United States was a shallow sea. A line of three volcanoes grew into islands. It may be associated with an ancient hot spot that was dragged west to east by continental drift. These three volcanoes are at Monroe, LA, Midnight, MS and Jackson, MS. This area has been extensively explored by the oil and gas industry. I have no heat data for the Monroe and Midnight volcanoes but- Jackson is indicated in red because there is still significant heat down there. Groundwater at depth is in excess of the boiling point. It would be interesting to explore the other two sites to see if there in still heat rising from their magma chambers. This heat has no where to go. Its trapped thown there and may provide access to geothermal power. Geothermal power may be an important answer to our future energy needs. All you need to produce electricity is to boil water to drive a turbine. Our difficulty is with fuels- coal, gas, oil and nuclear power all have downsides. Geothermal energy, if we can figure out how to utilize it, would have none of the down sides of fossil fuels or nuclear power. Regardless of where you stand on climate change, this is a problem that we need to solve. A power source that like geothermal energy that can't be depleted and doesn't pollute is very promising. _________________________________________ Sources: The Jackson Volcano - Wikipedia https://www.deq.state.ms.us/MDEQ.nsf/pdf/Geology_Volume018Number3September1997/$File/Vol_18_3.pdf?OpenElement

Compare and contrast the convergence zone St Helens with the Hot Spot Kilauea volcano. Pay attention. There will be a test. This is an excellent account of the Mount St Helens eruption. It was the biggest eruption in the continental US in modern times. St Helens is a fairly typical Cascades volcano. Kilauea volcano in Hawaii has been erupting continuously for thirty years.

Hot Spot Volcanism We understand Convergence zone volcanism but what about hot spots? What are they? How do they form? Hot spots are mantel plumes that allows very hot materials from as deep as the outer core to rise up and literally burn their way through the lithosphere. It can happen anywhere under a tectonic plate, deep under an ocean or even a continental crust. No one is really sure what these hot spots are, what causes them or why they can last for millions of years. It has been suggested that they are flaws in the mantle that allows convective forces to focus the movement of liquified rock on these points. These hot spots last so long in geological terms that as they stay fixed at one point. Tectonic plates are dragged across the hot spots slowly creating features like the Hawaiian Island chain or the Snake River caldera complex or the Yellowstone hot spot. US Geological Survey Article: Hot Spots or Thermal Mantle Plumes The basaltic lava that comes from hot spot volcanoes is very different from the kind produced by convergence zone volcanism. In many ways it is the chemical opposite of silica. rich Rhyolite lavas. It comes from much deeper inside the earth. It flows much more like iike a true liquid than a silica based lava which behaves much more like wet lumpy clay. Rhyolite has to be blasted out of volcanoes. Basaltic lava cools slowly and is content to pool and run like any other liquid. This liquid is somewhere in excess of 1200 degrees centigrade and will destroy almost anything it encounters. Basaltic lava flows can be enormous. The largest known volcanic event in the last 500 million years created the Siberian Traps and may have caused the Permian-Triassic (PT) extinction event from out gassing so huge a volume of magmatic gas that it changed the chemistry of the atmosphere. On top of the massive outgassing event, the Siberian Traps supervolcano deposited 1 to 4 million cubic kilometers of basaltic lava (240,000–960,000 cubic miles). The Columbia River basin in Washington State is a basaltic lava flow that occurred about 16 million years ago in Eastern Washington and Idaho and ran all the way to the sea. In some parts of Washington these lava flows are three miles deep. This picture comes from a Hawaiian volcano that has been erupting constantly for forty years. This type of lava cools unevenly. The top can cool and harden while inside its still molten. This type behavior is how lava tubes are formed. _______________________________________________ As I've run out of allowed images, that's all for today. we'll take it up there tomorrow.

What a good Southern name to join our forum. Welcome General! Isn't it about time for you to light the bat signal or something? The south is pretty restless these days. It might be just about time. *nudge, nudge, wink, wink*

Subduction Zone Volcanism Subduction Zone Volcanism Subduction zone volcanism occurs when one plate is shoved under another. In the case of the Cascades subduction zone that would be the Juan de Fuca plate sliding underneath the North American plate. To see more about it take a look at Cascadia Subduction Zone at wikipedia. This has been the focus of some of the most violent geology on the planet since the beginning of the planet. The mega-quakes, the volcanic eruptions and lava flows are that we modern humans have seen are child's play in comparison with some of the earth shattering geological calamities that this region, and others, have seen in the past. Juan de Fuca Plate Subduction zone volcanoes are quite different than hot spot volcanoes (which we will discuss tomorrow). As the plate subducts, it melts creating silica rich lavas like rhyolite- the kind so common around Mount St Helens. Rhyolite There are many subduction zones in the world. One runs through Japan. Another through Indonesia. Another through New Zealand. There is one that runs down Italy of which the famous Mount Vesuvius is a part. Another one runs through Greece. If you notice the volcanoes all have several things in common.They build huge, beautiful but explosive stratovolcanoes like Mount St Helens, Krakatoa, Mount Pinatubo. They are explosive because their silicate rich lava it thick and doesn't flow very well. They get all stopped up sometimes for hundreds of thousands of years (or thousands or even hundreds of years) and explode. There is some evidence that when groundwater gets in the magma chamber, flash to steam and provides some of the violence in these explosions. These volcanoes are killers and can devastate hundreds of square miles when they blow. Why are other obviously active volcanoes almost gentle? Tomorrow we'll talk about hot spot volcanism, how it is different from subduction zone volcanism and how these massive basaltic flows have formed much of the earths surface. Mount Hood ~50 miles east of Portland Oregon is a stratovolcano. It hasn't been active since 1805 but it still burps and gurgles. There have been microquakes underneath it since the seventies so there is lava in the magma chamber. It's known for great skying and snowboarding but there is a beast underneath.

#567 seems hot... think I'll give it a go

Hood's Wrath Sandy, Oregon Joey Hammond arrived at his home just before dark. A suburb east of Portland, Sandy wasn't far for a commute but, the traffic was brutal. He had to leave early and would arrive home late. He wouldn't have it any other way. Joey's house wasn't huge, but it was his favorite place to be. It was a split-level on a steep hillside on Bluff Road that always smelled of the NorthWest woods. No one would ever believe that smell if you put it in an ai

I went to see Logan. What I expected was a bloody action gore-fest without a great deal of depth. What I saw was a bloody action gore-fest with much greater depth than I expected. This was Logan in his finest hour as we've never seen him. This is Dr. X and Wolverine as we've never seen them: old, alone and vulnerable. It is difficult to see them that way. I shall not give away any spoilers but these are not the invulnerable characters they once were. Old age has, as it will anyone who is lucky enough to make it to old age, humbled them. Despite it all, they are still the people that they have always been. This is a classical theme and if i have not completely butchered my school boy Latin: tu quoque mortale. You too are mortal. Such things are not popular to consider but they are the bitter truth of this life.

Isn't this how every bad sci-fi movie you've ever seen starts? I think that I read somewhere that 7 out of 8 species that have ever existed are extinct now. The reasons for this are many like the great extinction events (whatever they were- comets are popular suspects but I'm leaning toward team Super-volcano) or an organism simply isn't hardy enough to adapt to changes in its environment. Like a super-volcano erupting and triggering a new ice age. The science on this is fascinating- the extinction theories, not the woolly mammoth which by all accounts had the horrible judgement to hang out in Siberia, Who didn't see extinction by deep freeze coming?

It's a sine cos you can't just talk about triangles without a tangential trig pun.

Our textbook covers it as both.

Holy crap. I survived the most brutal midterms I've ever seen. I've seen a few that were only for the true masochist. I was there for Doctor Gaddis's Great Calculus Massacre of 1983. Oh the humanity! Sadly essay questions have not gone out of style- as much as they should. Those of us with the gift of blarney have an unfair advantage that lets us leverage a little knowledge and make ourselves sound like we know what we're talking about. Describe the equations Maxwell's Equations are based on. Describe how Maxwell changed the original equations to make radio possible. Describe how you could easily crash and burn in this class. Describe how you worked your ass off and made sure that wouldn't happen. Describe how now that its over all you want to do is laugh maniacally and eat ice cream. Admittedly, I've always wanted to know what those equations meant. I did sign up for the class. I just wish it could be done without the associated psychic trauma. There's a reason that spring break comes right after mid-terms. I think it is because there would be more shootings if it wasn't.

Yes- I have written great many. In my experience, grant proposals mean absolutely nothing. I have never actually seen any evidence that grant proposals are ever actually read or their merits considered. Grants get funded based on a complex formula that includes family relations, in-laws, political cronies, old fraternity brothers and whether or not the granting authority, be it university, state or congressional, thinks the research or project is cool. Then the lucky project is funded for 25% of the requested funds so that it will fail completely. Good luck.

It sounds really scary but it really isn't. Actually- it is a natural evolution in the technology. Once upon a time there was RADAR and it was good. It was very, very good and gave the ALlies a major advantage in the second world war. The technology was proven and all the world powers wanted to use it for civilian and military purposes. It works like this: Every RADAR dish is a dual mode device: it sends out a signal and it listens for its return. Ignore the math- it's really that simple. Old Radar dishes look a lot like this: A single transmitter and a receiver, or if you are into tech-speak- a transceiver. Most RADAR acts in half-duplex as it sends a pulse and then "listens" for a return. The transitions in send-receive cycle are quite fast as we're talking about light speed wave. Big changes in RADAR technology took place over the course of the Cold War. One of the biggest one were breakthroughs in signal processing. Ironically this came from the Navy and their quest to make their Sonar hear better. A Signal Processor is usually a chip with firmware that can read and process a raw signal feed. This is great when you've got complex analog data and want to quickly change it into a form that is much more useful. These devices are smart so their software can be changed. They can do really neat stuff like filter out noise and process the return signal. You see it every time you watch the weather- that is how (among other things) Doppler radar works. SO... if we have this antenna with one transmit and receive element, wouldn't it provide better, sharper radar performance if we used MORE than one transceiver element? It is idea that phased array radar is based on. In the 70s the US Navy needed a new, powerful radar system to protect their carriers. The whole ship was designed around the Ticonderoga class missile cruisers were built around a huge phased array radar. The AEGIS system is built around the SPY phased array radar. Note the bulky conning tower- the whole this is a phased array.receiver. A different part of the system- this gives you a better look at a phased array- each square is an individual transceiver. This makes the area of the radar "receiver/transmitter" exponentially more powerful and sensitive. Look for this technology to be coming to your weather Radar soon. In the next decade the weather radar systems will be gradually replaced by a phased array pulse doppler system currently under development by a consortium of Universities and Industry. The new weather images will be so detailed that meteorologists can watch a tornado form and watch it develop in increments of fractions of a second until it dissipates. It's like an MRI machine for weather- they'll be able to see it from the inside. The phased array concept also works for simple receivers. In fact when NASA designed the New Horizons probe to fly by Pluto they needed an antenna that was powerful and sensitive enough to send and receive data over one of the longest communications loop in history. New Horizons flew with a phased array communications antenna and it performed flawlessly.

As I travel the wilds of the Internets, I am often astonished by the number of assholes that make such a point of being ass holy. There are a few in particular that I want to warn you about. Beware of these ragin bastards. They make a point of being rude and obnoxious to bait you into typing something that will get you banned. Many of them are master baiters. Without further ado, I shall warn you about some of the worst of the Flaming Assholes of the Internets The triggered activist Whether its save the whales or fat acceptance, you've gone and done it with your microaggressions, racisms and patriarchal attitudes. How dare you disagree! the Conspiracy Nut This asshole can't prove anything, has no evidence or even a clue. He is impervious to facts and can twist logic into pretzels. He has figured out every conspiracy from the Lincoln Assassination to Putin's secret agreement with the gray aliens to mind control humanity. I for one welcome our new masters if I don't have to listen the conspiracy theorists idiocy. the Expert Without Portfolio He is the only guy in the chat room that doesn't know that he's full of it. High Priests of Environmentalism People for whom environmentalism has become a religion. Emphasis on the mental part. Religious Nuts Whether they are yapping about Jesus, Allah or Vishnu, these guys are doing more for atheism than their own faith. The Fascists of Tolerance Their strategy is to call you names until you agree with them on everything. I don't think this has ever worked once. Enfant Provocateur The original troll, this kid is online for one purpose: to create chaos. You’ll know him when you see him. Just follow the riot. How can you know who is an asshole online you ask? It takes one to know one. I make no pretenses of NOT being an asshole. What annoys me about these people is that they won't admit it.

Cops have an impossible job. I give them as much slack as possible.

Prompt #552 With A Whimper

Free agency has wrecked the old order in the NFL. Coaches used to spend years building a playoff caliber team. Now every year he has to build a new team from last years leftovers. Belichick has built a system that works under free agency. It is a better system than anyone else has managed so far. Every year he'll lose a few players but, he fills the holes with the draft and adds few strategic free agent. Another thing that Belichick is brilliant at: half time adjustments. Most people didn't see this but when they came out in the 2nd half, the Patriot defense had a makeover. It wasn't done yet. They kept working on it until mid way through the third quarter when they shut down the team that had led the league in scoring. Now Belicheck said he didn't make any half time adjustments. OK, sure. His defensive coordinator did. Will I say that Brady or the Pats are the best ever? By the stats and the trophies, they earned it. I won't say EVER because that's a long time. Somewhere there's a kid playing in a sand lot that no one has ever seen that's really going to light it up. We have to see him before we hand out the best ever trophy. How about the best so far trophy?

Atlanta is going to be a farce to be reckoned with if they can keep their roster from falling apart in free agency. We (New Orleans) play them twice a year in a grudge match so we know them well. That rep for choking in big games goes back a long way.

Brady just put himself in the top 5. Montana was a joy to watch in his prime but he never had the teams around him that Belichick has built.
