It may be a little quiet here for a while…

October 20, 2007

My PhD defense date is approaching fast and furious. I still have much to do to wrap up the final chapter. It’ll all happen, but posts on this blog will likely be infrequent and/or brief for the next several weeks. It’s time for the final push…time to focus and get into production mode.

Okay…back to work.

Where on (Google)Earth? #63

October 19, 2007

Slowly but surely, my Wo(G)E record is improving…thanks to Zoltan putting the Danube River delta up for #62. Being a lover of deltas, I knew I had seen it and it only took a minute or two to remember.

For Wo(G)E #63, I have an oblique view…no scale. The features are pretty obvious so it might be relatively easy. If you are new to Where on (Google)Earth, it is open to anyone…all you need to do is find this location put the coordinates in the comments below. Although not required, us Wo(G)E veterans try and include a little information about the geologic/geographic feature(s) and sometimes share our story of how we went about finding it.

Good luck!

And, one more thing…for you veterans out there, the Schott Rule is in effect. The Schott Rule is, and I quote:

Previous winners must wait at least one hour for each win that they have before posting a solution – other comments would be okay.

Post time is: 0820 PDT

If you are new to Wo(G)E, you are free to post the solution as soon as you find it. And the winner gets to host #64 on their blog. If you don’t have a blog, you can still play and win…we’ll just figure out the next host some other way.

Some thoughts about the rising price of crude oil

October 16, 2007

The cost of a barrel of crude oil went above $88 today for the first time. Since we humans love nice round numbers, as it nears the $100 mark we will start to hear more and more about the issue in news reports.

While some fear the rising prices could wreak economic havoc and even a major depression, I fall into the camp that believes higher fuel prices might be beneficial for changing the collective behavior and attitude towards energy consumption. How much does a gallon of gasoline need to cost before Americans seriously change their ways (or affect change in the marketplace with their consumer behavior)? $5? $10?

But, at the same time, we don’t want prices to rise by too much too fast. Even if you don’t personally own or use a car, the cost of transporting goods from A to B will lead to increased costs for the everyday consumer.

So, I’ll pose this question to all of you. How much is enough to affect change but not cause the Great Depression II? Does it even matter? What are your thoughts?

UPDATE:  This post was published a few hours ago…and since then I was thinking about this some more. I mentioned that I fall into the school of thought that high (but not too high) energy prices might be good in the long run. So, how am I preparing for that?

I don’t claim to be someone with all the answers, nor do I claim to be someone who can be excluded from the problem. I hate that ivory (or is it green) tower rhetoric. I am certainly part of the problem. That being said, we (me and my girlfriend) are trying to take steps to reduce our overall consumption.

  • we share one high-MPG car (>30 mpg) between the two of us
  • we take a commuter train to work instead of driving (~90% of the time)
  • we live in a city where we can walk and/or take public transportation for many (but not all) errands or entertainment
  • our city has a great composting program now, so we get those biobags and try and compost as much as possible
  • we are trying to be mindful of purchasing items with wasteful packaging (e.g., no bottled water…tap water is fine)

I don’t know if these steps make much of a difference. But, in a way, it’s more about changing attitudes towards optimizing energy usage and efficiency. I don’t know…if we ever have kids, they’ll hopefully grow up thinking doing all these things (and much more) as “normal”.

What else could we do? A lot, i’m sure. We looked into a hybrid, but simply could not afford it. And, the one thing that keeps our “footprint” higher than we’d like is flying. We both have family scattered about the country and like to visit them multiple times in one year.

If you have thoughts or ideas about this, feel free to chime in below.

Note: Related to this topic, back in May, I posted my review of the film End of Suburbia, which addresses predictions and speculations about what happens to the contemporary American lifestyle when oil (and thus gasoline) gets too expensive.

The Accretionary Wedge #2: Gravity’s relentless onslaught against humanity

October 15, 2007

The second edition of the geoscience carnival The Accretionary Wedge, is hosted by Kim up at All of My Faults Are Stress Related. The theme is Earth hazards…or, how our planet might kill you. My contribution to this is not as grand as I’d envisioned…this whole finishing-the-PhD thing is taking a significant bite out of my blogging.

~~

Gravity’s relentless onslaught against humanity

gravityapple.jpgAh yes…gravity…it’s responsible for the coalescence of material to form our planet, it is a fundamental force in our universe (it also makes alpine skiing so much more fun than cross-country), yet it is also constantly trying to destroy us and the stuff we build. It is relentless. Sometimes slowly and imperceptibly, sometimes abruptly and spectacularly. Gravity, with the aid of weathering and erosion, is constantly battling the tectonic forces attempting to push our crust upwards.

When tectonics is winning the war (i.e., there is high relief), gravity really steps up its attacks and can win some major battles from time to time. Although these events are occurring all the time all over the planet, we typically only hear about them when they are (1) of large magnitude, and (2) directly affect human life and/or property. Just a couple weeks ago, residents atop San Diego’s Mount Soledad experienced some gravitational “adjustments”.

slide-laconchita.jpgThese gravity-induced processes, known as mass wasting, are subdivided into numerous types of slides, falls, slumps, creep, flows, and so on. The geology of the bedrock and climate play a huge role in determining what types of processes, the location, how often, and how severe these events are. The photo at left is the recent La Conchita slide in southern California (go here and here for more). In this case, heavy rains, weak Holocene sediments, and high relief all converged and created this relatively small slide. In other cases, however, entire villages can be wiped out by mudslides.

The slides and falls are obviously the quickest and most violent, but gravity never tires and will work over long periods of time if it has to. Soil creep and subsidence are slow processes that work to destroy our property and infrastructure.

And don’t think that the ocean is off limits to gravity’s onslaught. Submarine slides and flows threaten our sea-floor infrastructure as well (there’s a lot down there). The image below outlines the deposit of a single submarine slide near Palos Verdes, California. Some of the blocks in the ‘blocky debris’ are as big as large office buildings. Read more about this event here.

Finally, this video, which could not be found on YouTube for a while, has returned. It is of a landslide in Japan. If the embedded video is broken, go here.

We will never beat gravity. Gravity is relentless. But, if we continue to work to understand the processes and patterns related to these events, we can do a much better job of, at the very least, knowing where not to put our house.

Evolution in cyberspace meme

October 15, 2007

Apparently, i’ve been tagged for an incredibly dorky meme. This is right up my alley.

Okay…I’ll admit it. I had to look up what this meme’in’ within the context of blogging is all about. I’m not the sharpest tool in the shed, but trying to keep up.

So, here’s what I’m supposed to do:

There are a set of questions below that are all of the form, “The best [subgenre] in [genre] is…”. Copy the questions, and before answering them, you may modify them in a limited way, carrying out no more than two of these operations:
* You can leave them exactly as is.
* You can delete any one question.
* You can mutate either the genre, medium, or subgenre of any one question. For instance, you could change “The best time travel novel in SF/Fantasy is…” to “The best time travel novel in Westerns is…”, or “The best time travel movie in SF/Fantasy is…”, or “The best romance novel in SF/Fantasy is…”.
* You can add a completely new question of your choice to the end of the list, as long as it is still in the form “The best [subgenre] in [genre] is…”.
* You must have at least one question in your set, or you’ve gone extinct, and you must be able to answer it yourself, or you’re not viable.
Then answer your possibly mutant set of questions. Please do include a link back to the blog you got them from, to simplify tracing the ancestry, and include these instructions.
Finally, pass it along to any number of your fellow bloggers. Remember, though, your success as a Darwinian replicator is going to be measured by the propagation of your variants, which is
going to be a function of both the interest your well-honed questions generate and the number of successful attempts at reproducing them.

Okay, here are my answers:

The best scary movie in sociopolitical dystopias is: A Clockwork Orange (Stanley Kubrick film adapted from Anthony Burgess novel of the same name).

The best sexy song in jazz-funk is:Double Game” by Jennifer Charles and Billy Martin.

The best whimsical story in adult short stories is:On Having No Head” by D.E. Harding (most interpret this as about spirituality and zen stuff…I think its whimsical!)

I was tagged by Kate…she was tagged by Coturnix.

I now tag Thermochronic, Sabine, and ChrisR.

Friday Field Foto #32: Load structures in shallow-marine sediments

October 11, 2007

I went out to the coast recently for fun and was reminded of some photos I took a few years back of the rocks exposed along the beach cliffs. This week’s photo shows some fantastic loading features.

Unfortunately there is no person standing with this photo for scale, but the very convoluted boundary between the lower darker siltstone and the much whiter overlying sandstone is about 2-3 people high. These features are essentially recording the sinking of the white sediment into the darker sediment below. Think lava lamp. This little illustration here shows it nicely.

Inspiring talk from Cassini researcher

October 10, 2007

I’m a huge fan of the talks up at TED. Every so often they release talks from this past year’s conference as well as older talks from the past several years. One of the newest on their site is a talk by Carolyn Porco, a planetary scientist and leader of the imaging team for the Cassini-Huygens mission to Saturn and its moons.

I can’t figure out how to embed their videos on WordPress, so go here to see it on the TED website. Believe me, if you have 20 minutes, you should watch it. Not only are the images breathtaking but Porco’s delivery is exciting and inspirational.

Dissolved feldspars or food poisoning?

October 10, 2007

I’ve been out of commission the past 36 hours with one of those quick-onset and intense stomach illnesses. I’m feeling better but it is lingering. It hit me on Monday afternoon while I was point-counting some sandstone thin sections. The culprit may very well be something I ate or some wily virus. But another hypothesis is that my body just simply could not handle the prospect of having to point count multiple samples containing feldspars largely replaced by calcite.

feldspar1.jpg

The photo above (from here) shows this nicely. I will be taking photos of my samples soon and will post some of them. They look a lot crappier than this. I think this is what made me violently ill…or maybe it is point-counting in general.

Some Where on (Google)Earth stats

October 7, 2007

It’s been a slow weekend for me…went and saw some music in the park yesterday, which was a lot of fun. Doing some reading this afternoon getting my head into sedimentary provenance studies.  I am doing some point-counting this week…the last piece of the puzzle for my entire dissertation. All the other data (detrital zircons, shale geochemistry) is analyzed; the sandstone petrography will be done by the end of this week (or maybe next week). I’m not looking forward to it, but I just gotta get in the zone and get it done. Almost there…stay on target.

One thing I did do this weekend blogging-wise, was quickly compile the statistics to date for the Where on (Google)Earth challenge.

woge_stats.jpg

The dominance of Ron, with 20 wins, is quite evident. My two wins is pretty pathetic…maybe I should spend some time today working on Wo(G)E #59 over at Active Margin. Hmmm….reading about QFL plots….playing with GoogleEarth?

Hardly Strictly Bluegrass

October 5, 2007

It’s an October tradition here in San Francisco — the Hardly Strictly Bluegrass Festival. Started in 2001 as the Strictly Bluegrass Festival with 9 artists on one day, it has grown into a 3-day event with over 70 artists spanning more than just bluegrass (hence the “hardly”), but still with a nice twangy feel to it.

I’m one of those people that fall into the category that despise modern country-and-western “pop” music. It’s trite and makes me throw up in my mouth a little bit. But, I do like so-called classic country and really like bluegrass. This festival is perfect, because a whole day of only bluegrass can get a little old (to me), so the other acts that blend more folk and/or rock keep it fresh.

And…it’s FREE! I really love that. Here are the artists I most excited to see perform:

Ricky Skaggs & Bruce Hornsby
Gillian Welch
Bela Fleck
Steve Earle
John Prine
Keller Williams
Boz Skaggs
Robert Earl Keen
David Grisman
Jorma Kaukonen
The Del McCoury Band
