Making waves
Back in April I showed a multibeam bathymetric (sea floor topography) map from offshore Half Moon Bay not too far down the coast from San Francisco.
PopSci has a nice little article talking more about how the underlying structure that produces the sea-floor topography as well as the coastal promontory focus the wave energy toward a point called Mavericks. This has some of the biggest waves on the west coast of North America and hosts an annual surfing competition.
Creation fantasy camp coverage over at Pharyngula
As most of you know by now, a creationist “museum” is opening in Kentucky and receiving a lot of fanfare (mostly of the mocking and negative sort, thankfully).
I briefly considered writing a post about it, but then found Pharyngula’s incredible compilation of media and blogosphere reactions to the story.
The reaction from science-minded bloggers is overwhelmingly negative (correctly so) toward the opening of such an amusement park. But, as Pharyngula points out, the media as their heads up their asses:
Journalists, you have a problem. Most of the articles written on this “museum” bend over backwards to treat questions like “Did Man walk among Dinosaurs?” as serious, requiring some kind of measured response from multiple points of view, and rarely even recognized the scientific position that the question should not only be answered with a strong negative, but that it is absurd. Let me ask any reporters out there: when you cover a story about a disaster, say the destruction of a town by a tornado, do you also feel obligated to get a few pithy quotes from a few people who want to argue that the disaster was a good thing, or that the residents deserved it?
Head on over to Pharyngula for much, much more.

Sunday morning funnies – expanding Earth theory
Grab yourself a cup of coffee and enjoy some Sunday morning funnies.
I can’t decide if this is for real or a parody of someone trying to be serious, or something else. Either way, it is entertaining. Neal Adams, an American comic book artist, has a website and various videos out there talking about the expanding Earth theory. That’s right…the spreading of the Atlantic and eastern Pacific indicate that the Earth has to have grown in the last couple hundred million years. What about subduction? This is what Neal says about subduction:
There is no subduction. No plates subduct. Subduction is unscientific and untrue, the ramifications of which are world shaking. And… the Earth grows! (You may have heard this before, so I caution you. This is not your father’s Earth expanding theory.) Earth is growing, not expanding, and therein lies the past-error who’s answer lies in physics and not geology.
Very compelling argument against subduction. If you are in the mood for some fun reading, check out Neal’s full treatise on why subduction is a stupid theory.

That was the “scientific” part, but wait…there’s more. Here, Neal is getting a little nasty:
40 years ago your discipline was in a position to lead all of science into a new age of discovery but you wimped out. You, basically, had no balls.
You could have given a growing Earth theory an open chance for a complete examination, but you closed your doors.
WORSE, you accepted subduction, a theory that has not been seen or proved for all these 40 years, as gospel out of fear.
Why did you do it?
You were bullied into it. But worse again you allowed yourselves to be bullied shame!
Nothing, nothing in the “proofs” of subduction is there that can’t easily be explained by another concept within the plate tectonics.
You will be the laughed at generation of geologists who believed in the subduction theory. Just like those who believed the Sun went around the Earth or the Earth was flat and you could fall off the edge. You are the duped generation of geologists.
I never realized some people were so strongly anti-subduction. Anyway, now that subduction is neatly out of the way, Neal gets to his real message. If plates don’t subduct but they are created at spreading centers then — the Earth has to be growing!
Check out Neal’s video below explaining the expanding Earth theory. It’s several minutes long, but well worth it. If embedded video is broken, go here.
I do like Neal’s illustrations and animations…very well done. Perhaps his science page is simply a different outlet to produce his art, I don’t know. If anyone out there knows the skinny on this guy, drop a comment….this was one of those things I found on the internet and now I need to get back to work.

End of Suburbia
I recently watched the documentary End of Suburbia and, inspired by Thermochronic’s comments on gasoline prices, I figured it was a good time to post my thoughts about the film.
This documentary is essentially about Peak Oil, which is the notion that we are very close to producing half of the Earth’s oil reserves (if we haven’t already). What this means is that once we hit that peak, production will decline. Couple this decline in supply with an increase in demand over the next half-century and we have a recipe for global disaster…so say the most adamant peak oil theorists.
I’m not going to spend time on this post discussing peak oil as such. If you don’t know much about peak oil, it behooves you to learn a bit about it before watching End of Suburbia. There are differing viewpoints from petroleum geologists as well as economists regarding the validity of global oil production being described by a bell curve, but let’s save that for another time. So, for the rest of this post, i’m going to focus on the film.
This film discusses the theory, evidence, and implications of peak oil within the context of the American suburbs. This is what I like about this film. The information and commentary regarding this issue are woven into a narrative about the origin, rise, and predicted demise of the suburban landscape. Instead of a boring encyclopedic presentation of what peak oil is and what it means, the creators of End of Suburbia asks a key question: Is suburban living sustainable? The subtitle of the film is Oil Depletion and the Collapse of the American Dream so you can probably guess what they think the prospects are.
The American suburbs evolved from the combination of post-WWII prosperity and the rise of the affordable automobile. That is, everyone can have a car. Why? Because cars are relatively cheap? That’s part of it for sure, but more important in this equation — cheap and abundant fuel to run the cars. They do a great job in the film of emphasizing the underlying issue of peak oil: it’s not about running out of oil in an absolute sense…it’s about running out of cheap oil. It is an economic as well as geologic issue.
So, fast forward from the prosperous and enthusiastically pro-capitalism 1950s to the turn of
the century. We now have a situation where many people drive over 100 miles a day to commute from their unnecessarily large (and poorly constructed) home in the suburbs to their place of work and back. The original suburbs of the 1950s/1960s feel like the inner city compared to these ‘exurbs’ that are far out on the fringes of a metropolitan area, the so-called suburban sprawl. These areas are designed around the automobile. This is the only way to get around. You know these places…we all do, that’s where you can find Target, Chili’s, Best Buy, and all the other mega-stores. Try being a pedestrian in this environment and you certainly risk your life.
So, now as Americans are feeling the effects of more expensive fuel it is getting more difficult to sustain this lifestyle. The film does a great job of painting a rather bleek picture of the future of this kind of life. Like most documentaries, End of Suburbia includes a combination of narration that presents the information and interview clips with various people for additional information and commentary.
The last part of End of Suburbia takes a turn from the thesis of a doomed civilization to more optimistic thoughts. They discuss the ideas of people returning to urban settings, sometimes referred to as ‘new urbanism‘, where most of what residents need for everyday life is within walking distance (or at least a much shorter trip on public transportation or car). The filmmakers also touch on the idea of buying locally grown and produced goods to cut down on the ridiculous distances the stuff we buy and consume is transported (why do I need an apple from New Zealand in California?).
Personally, I loved this film. I was raised in American suburbia and didn’t think about what it actually was and how it was set up until recently…that is what I knew. For me, these kinds of films (or books, essays, websites, etc.) are important for my own education and awareness.
Call me a pessimist, but I tend to think that it takes significant events to produce significant change. Will we need to experience a Great Depression II to collectively change our ways? I hope it doesn’t come to that, but I fear it will. The best-case scenario in my opinion would be continued high fuel prices to wake the public up to the realities of our energy situation. I have set up my own lifestyle to anticipate the future higher gasoline prices (i.e, buying a high-MPG car, having only one car for two of us, taking the commuter train as much as possible, living in a neighborhood where we can walk to the market, taking the bus when we can, etc.).

Friday Field Foto #18: Lousy outcrop
Where on (Google)Earth #12?
Ron has owned this competition for the last several installments…but he is supposed to away from a computer…so you others out there may actually have time to search around for this one.
Good luck!
Click on the image above to see a whole bunch of great photographs of the Klyuchevskoy Volcano on Kamchatka, which has been erupting for the last few weeks.

Visualizing complex networks
I came across this interesting website, called Visual Complexity, that has a collection of images from various projects that aim to map and produce visualizations of complex networks. These include biological, computer systems, social networks, the web itself, and others.
The image below is a map of the blogosphere from here.
The value of these to me aren’t so much in using them as a map….as in to navigate the blogosphere with the above image….but to appreciate the nature of networks.

Debris flow video … updated
A few weeks ago I posted a video of a debris flow event caught on film in California. At the time, I did not know much about it. Thanks to a YouTuber, we can now see a much longer video and we know much more about the event (thanks bapyou!).
If the embedded video doesn’t appear below, go here. This version runs a little over 4 minutes and has a bunch of information up front about the the actual event.

NEPTUNE sea laboratory
NEPTUNE (North-East Pacific Time-Series Undersea Networked Experiments), which I posted about last month, will be a state-of-the-art observational system in the ocean and on the sea floor off the coast of Oregon, Washington, and British Columbia. It will deliver data real-time and be interactive
This is very exciting. The Earth’s oceans are the last frontier on this planet regarding scientific exploration and observation. We still have yet to actually document many of the processes that occur in the submarine realm. The NEPTUNE website (check it out…it’s pretty cool) lists a few of these:
- massive storms
- erupting submarine volcanoes
- giant earthquakes
- marine mammal feeding and hunting patterns
- phytoplankton blooms in the upper ocean
- releases of microbes that live in the rocks beneath the seafloor and thrive on a diet of volcanic gas
And, of course, what everybody wants to see caught in the act — turbidity currents!
Oh wait…I guess that’s just me.
Sediment transport is indeed one of their goals…I will be very interested to see the data come in and published in the coming years.
