Mini Book Review: The Hitchhiker's Guide to the Galaxy
Started out thinking it was brilliant, then it kind of lost steam for me, and all in all I liked it but it wasn't as fast or breezy or even fun a read as I thought it would be partly because of the use of words--lots of comma splices that threw me off--and partly because I wanted to get my mind at least a little bit around the concepts (playful though they may be) and I'm not much of a time-and-space gal. I remembered while reading it why I never liked science fiction: It terrifies me. I have to think about the things that make me most uncomfortable, which in a nutshell is only one thing--infinity--and more specifically are time, space, death, and things I don't understand. (Which I guess may trump infinity as the most basic thing, and why I'm uncomfortable with infinity. Any level of contemplation will not get me closer to understanding any of these things, whereas I *can* understand many things on this planet that I don't, yet.) And I know any scifi friends reading this will feel completely smug and self-righteous, thinking yes, that's the whole point. Well, bully for you. I'd love to discuss it... but not with you. (Unless you're *not* smug about it. In which case, we can talk.)
Holy cow, I can't comprehend this universe, let alone another one...
It was interesting to find how many things I remembered from high school, like the Babel fish, which I want. And I love how outdated the actual guide is. "It's a sort of electronic book..." It still has buttons on it! How quaint. And a small screen.
The future is now, people.

Ahhhh, camping. My friend Nancy organizes an annual trip to Glendo State Park, a recreation area around a big ol' reservoir in the middle of Wyoming just about three hours north of here. I feel like I should dig into the geology of the region, but I also feel that I'm dehydrated and underfed and sunned and road-tripped and tired. So some pictures of grasses, instead.
I kept feeling like I should stop on the side of the road to take pictures of the grasses, gentle hills, and more grasses on the way up. I'm wondering if that Microsoft background is from Wyoming. There were some GREAT rock formations, but I couldn't be bothered to stop for them. I finally bothered here, for some hills and grasses.
Like I said, the drive should take just a hair over three hours.
I was going to leave on Friday but my weeks are often (always?) hectic and I didn't have time to pack on Thursday night and the person who was going to ride up with me bailed besides. And on Friday afternoon burnt out from the week I didn't feel like being in a hurry so I had a beer after work with coworkers. And then I needed to pack and then it was 9 p.m. and then I realized / was convinced by a friend that it would be a pain to get up to Glendo that late, because it's a state park and I'd be that person driving around shining lights into tents at 1 a.m. trying to figure out where to set up, which would have likely resulted in sleeping in my car. (Not the first time.)
So I went to sleep early, so I could get up early and on the road. But then when I woke up, not exactly early, I realized there was really no pressing reason for me to rush up there. I went back to sleep, woke back up, made myself breakfast, grabbed my stuff, and went for an oil change. Oh, right, and my dashboard lights weren't working, which was another reason to not drive up at night. The main guy helping me at Grease Monkey came into the tiny waiting area with his fists on his hips. I have to come in in a Superman stance, he said, because I got your dash lights working. Turns out there's a dimmer switch. So he fixed the problem by, yes, turning the knob.
Got gas. Got out of town.
On the way, a few signs tempted me. There's an old west museum in Cheyenne, and that sounded like it could be cool. But I passed it up. (Maybe I'm in a hurry? Maybe I'm not? Do I feel like a museum? Not really...) Then another set of signs for exit 92. Historical this, historical that, and a site where you can see wagon wheel tracks from the Oregon Trail.
What?? Now *that* sounds cool, and it sounds like a site a friend who had done a massive road trip last year had told me about. (Thanks Seth.) So I exited. 15 miles. That's not a big deal, right? Okay, half and hour out of my way, at least, just for driving, but whatever. I'm here, and so are those tracks.
Somehow, I didn't arrive at our campground at Glendo until about 4 p.m. I'd left Boulder at 10:47 a.m. So much for three hours. What took me so long? Well, there was that stop alongside the road to take pictures, there was a stop for tonic (I had some limes hanging out at my place so the only logical thing to do was to buy a huge bottle of gin to go with them), there was the detour to the tracks, and there was a stop at the gas station right before the state park for ice and a hot dog. And an ice cream. Yes, you heard me. Ice cream and a gas-station hot dog.
I guess it all adds up.
And then.... Glendo. I've always been skeptical of Glendo. Somehow it seemed far away and not very much fun. But, I mean, look at it. A campground in the shade of trees on a big body of water to play in.
And as far as I can tell, this is mainly what happens at Glendo:
That, and some reading, and eating. Drinking. Paddle boarding. Relaxing. Playing. More eating. (I was very excited about the Saturday-night potluck.) Dog-petting. Hanging out around a fire. Storytelling. Hammocking. Sleeping.
There were three babies in the camp, and no one got a picture of them. I felt like I should have. I felt a little guilty. But I didn't feel like getting up to get my camera. I'm trying to get better with this phrase: Not my job. So, getting a picture of the babies wasn't my job, but there's little Lumin's hat, above, to represent the baby contingent.
I kind of wish there was another Glendo next weekend.
Sign me up for next year.

GPS in the Eastern Sierra, Year Six (and Counting)
At the end of May, I made my annual pilgrimage to SNARL, the Sierra Nevada Aquatic Research Lab, at the base of Mount Morrison in the Eastern Sierra. Big heart. The purpose: teaching Indiana University undergrads about GPS. The bonuses, starting with the drive down: mountain views.
This is my sixth year helping out with the class, which has been going for I think 12. I get grandmothered in as GPS instructor/engineer, which actually fits my current job quite well. The class is taught by my Indiana University master's advisor, Michael Hamburger, and John Rupp, from the Indiana Geological Survey. They are helped out by an Associate Instructor and together hold court over 15 students for a California mountain adventure.
What I love about this class (other than the amazing scenery): Unlike most geology field courses, it is an *intro* course, open to non-majors. This year, there were three geology majors, a history and political science major, a few biology majors, an environmental management major, and a speech pathology major, among others. And because it's Indiana University, in the heart of the midwest, many of these students have never seen these mountains before. Some have never really seen *any* mountains before. So every day is a wonderful new discovery. They get to ride a gondola for the first time, up Mammoth Mountain. They glissade for the first time, they see Death Valley for the first time, they soak in hot springs for the first time. And, they eat Linda's cooking for the first time. (Linda's been doing the catering since the beginning or almost the beginning of the course some twelve years ago, and it's an amazing thing. Don't come with any expectation of losing weight. The hiking is more than balanced out by Linda's desserts. Sigh.)
Oh, and they do GPS for the first time! (The most important thing, right?) One day of the course is surveying day, and we measure a line of survey markers up and across a fault using leveling (old school) and GPS (new school), so they can compare the techniques. The fault is the Hilton Creek fault, but we measure its displacement across McGee Creek, just a hair south of the field station where we stay. (Turns out faults don't care about their namesakes when they rupture).
This is how the day is supposed to go:
"Wow, we spent a lot of time trying to located these (small, hidden) survey markers amidst the sage brush and scrubby trees, and even though the written directions from years past seem pretty good it took forever. But that GPS stuff—WOW! It got us right to the point!"
To explain: We use what's called real-time kinematic methods, or RTK, which means we have a base station (GPS) that communicates with our rover (also GPS) via radios. We tell the base station where it is. No, base station, even if you think you're over there, you're not! You're right here! And so it can actually calculate the errors in its position. Because our rover and base are close together (a few km at most), they share the same error sources. Mainly, the satellite signals are going to travel through the same slice of atmosphere to reach our instruments, which means they're going to be delayed by the same amount to our base and rover, and that error essentially cancels out. It's convenient. And I program in the locations of the survey points beforehand, so *theoretically* we can navigate right to the points. And by "right to," I mean we should get within 2-3 centimeters, or about an inch. It's cool when it works.
And it *would* have worked this time if I had just chosen good coordinates. I happened to use coordinates from a year where the survey was bad for some reason. I had maybe eight years to choose from, and two were bad, and I used one of them. So in the field we were off by one meter, then two, then five. Not very impressive. But that was only a side goal of the survey. The main goal was to re-measure the positions of the markers to see if they'd changed.
[I like to teach one student in each group how to run the controller, and then they teach the next person, and so on, until everyone has used it to measure a marker. When possible, I have the old group teach the new group when we switch off. They always do great.]
And, the students seemed to like it. Some of them were totally grooving on it. The first group I had helped me set up the base station, and they were waaaaaay into it. A couple of the students even matched the equipment.
The idea of the survey is that we'll see motion on the fault, if there is any between surveys. So far, no luck. But I feel like we did a good job of surveying this year, so if there had been any motions, we'd have seen it. Michael and I manage to almost-but-not-quite work our way out of the tangle of data every year to make some sense of it, but with one or two days and an Excel spreadsheet and undoubtedly small motions, if any at all, we've never really had a "wow" product to show the students. By the next day they're on to the next thing, anyway, so I don't think they mind. But it would be really nice to show some real, meaningful results from the survey.
As it is, I attempt to entertain them with a few lectures—one to show how GPS works and what makes our fancy high-precision stuff different from the GPS in their smartphones, and another to show applications of GPS. Earthquakes! Volcanoes! Even hurricanes, snow depth, soil moisture, drought, and glaciers! And I show off about the Plate Boundary Observatory, which includes several sites within almost spitting distance of the field station where we stay.
[Leveling. More precise in the vertical, but it *only* gives the vertical. Plus, we cruise right past them once we're set up. Plus, we can navigate right to the markers...usually. Still, if there are changes, but the changes are very small, leveling might be the way to go.]
And then, at the end of the exhausting days, we eat Linda's food and soak in those hot springs and giggle in the "executive suite" dorm room like we're in... well, college. Or maybe junior high.
And maybe, just maybe (it's not uncommon), one or two of the students who weren't geology majors decide to study geology, or a student ends up in something else with an Earth science or environmental focus. One went on to study environmental law. The 2008 group started a Facebook page, and posts still show up periodically about the ecology or geology of the Eastern Sierra. We have yet to rope in a geodesist. But I like to think that the students at least have a better idea of what technology can do for us when it comes to understanding and mitigating hazards.
A major bonus for ME is getting to hang out with my dear friend Anne Hereford, who helped teach the class for six years and still comes out to visit. Here, we're taking Sunday afternoon off to hike up Convict Creek after lunch on the lake with the class. AMAZING geology. Just plain beautiful, whether you understand the folds or not. And the company was pretty darn okay, too.
Epilogue Part 2:
The drive back north is almost as nice as the drive back south, except the destination is not quite as nice. Hope to see you next year, Sierra class.

So I am eating soup—the same soup I've been eating the past few days—and as I'm eating it I realize I don't really want to use a spoon, because it's a a blended soup, and so I thoroughly lick off the spoon and reach out from the couch to drop the spoon onto my satchel beside me. Where there's.... another spoon. Because I did the exact same thing yesterday, and didn't remember until I saw the spoon.
The same thing happened yesterday. Where *did* I put that fork? I washed it, and then where did it end up? So I washed another one. And didn't want to put it in the drying rack for some reason. So I put it on top of an upturned clean bowl. Right next to another clean fork.
The best, though, was earlier this week when I got myself some tea. I drink a lot of tea. When I drink tea, if I use a tea bag, and if that tea bag has a tag, I tear off the tag. I tear off the tag because I don't like when it gets accidentally tugged into the tea when I'm pouring in the water, and then I have to fish the tag out with my fingers from the tea I'm about to drink. So I get up from my desk, pick up my mug, go to the sink down the hall, pull out yesterday's dry tea bag and toss it in the compost bin, get a new tea bag, pull off the tag, and read the tag while I fill my mug with water. Sometimes I like the quote or phrase on the tag. If I do, I feel like I should keep it with me somehow and read it again sometime, so I put it in my back pocket. I liked this one. I put it in. But I realized as I was putting it in that it was silly to do so because the last I remembered putting my hand in my pocket I found a mass of not-so-legible tea-tag fuzz. There was one other very intact tea tag in there, so I pulled it out.
At least I'm consistent.

Sea Level, on the Rise
Every once in a while, I do something that’s serious. Okay, often, I do something that’s serious. This is one of them. I played journalist a few weeks ago and interviewed Tad Pfeffer, a glaciologist at CU-Boulder, about the recently released IPCC’s Fifth Assessment Report. They’re somewhat few and far between, and this is the year. What do they tell us? The state of climate science and what we understand about climate past, present, and future—as best as we know at this time. I loved the process of doing the interview in the way that I first thought I would love doing journalism—I loved the learning. I learned as much as I could in the time I had allotted so I could actually conduct a somewhat intelligent interview with Pfeffer. That was the goal. Whether I accomplished it or not doesn’t really matter so much at this point, because I loved feeling like a journalist. And I learned about the IPCC report, knowledge that I can now build on moving forward.
[A once-flat, hundreds-of-meters thick Guyot glacier in Icy Bay, Alaska, now cracked as bedrock emerges in Guyot's rapid retreat. Had to use this image after I saw it was taken by a former co-worker, who was a PhD student of Pfeffer's. (Photo: Shad O'Neel, USGS)]
But enough about my process. Curious about sea level changes? Wondering when Miami is going to be gulping for air? We didn’t talk about the latter, but we did talk about some very interesting dynamics. Here are the most salient tidbits, and then you can read on if you want more:
- The International Panel on Climate Change (IPCC) is an intergovenmental body open to all members of the United Nations and the World Meteorological Organization. 195 countries are currently members. It doesn’t conduct research or collect new data, but rather “reviews and assesses the most recent scientific, technical and socio-economic information produced worldwide relevant to the understanding of climate change.” (Straight from their website.)
- The IPCC has released reports in 1990, 1995, 2001, and 2007, and the full current report will be released in 2014. The reports consist of three parts from three working groups: physical science (climate past, present, and future), societal effects, and mitigation (both preventing and addressing the effects of human-induced climate change). At the end of September, the summary of the sciency part was released. The other two bits will (theoretically) build off that science.
- The recent IPCC Working Group I report consists of 14 chapters. Each chapter represents a major topic in climate science, with the exception of the introduction, and is authored by many scientists. This is not new research, but a summary of what’s out there.
- Tad Pfeffer was one of 14 lead authors on the chapter about sea level change.
- Sea level rise is accelerating. Global sea level increased an average of about 1.5 mm per year from 1901 through 1990, more or less. Then, from about 1993 to 2010, that rate went up to 3.2 millimeters per year.
- Current estimate have sea level rising between 26 to 98 centimeters by the end of the century (2100). The range is broad because what sea level does depends on what the climate does, which depends in part on what we do. Various scenarios are accounted for.
- Looking at the global mean sea level neglects local and regional effects. The sea surface is not uniform! It actually has topography that varies by up to two meters, or six feet.
- Small glaciers are the major contributors right now to sea level rise as far as water goes, even though the vast majority of ice on the planet is hoarded by the Greenland and Antarctic ice sheets. The contributions of these giants are catching up to the little guys. Total potential contribution breakdown: Antarctic ice sheet wins at about 70 meters of sea level rise (that's more than 210 feet), then Greenland with 7 meters, and then all the rest of the glaciers of the world with a whopping... half a meter. But half a meter matters, if you live in southern Florida. Or Bangladesh.
- The biggest contributor to sea level rise is not melting ice at all, but ocean expansion. As the ocean warms, it expands, like just about any other medium would.
- Did you know that the gravitational pull of ice sheets pulls sea level up locally? I didn't. So, when a big body of ice melts, there are two effects to consider: Sea level rise from the addition of water, and sea level drop from the loss of the mass of the ice on land.
Interest piqued? Read on (and see some cool graphics). Or, take a listen, if you’d rather, to the original interview, with full “um-ness” on KGNU’s How On Earth archives.

What's Up Down South
This is the iceblog, after all.
The effect of the government shutdown on research in Antarctica has made it to the news, but of course can't get to the full extent of what's happening. I can't, either, but at least I can maybe offer up a little extra insight, since I'm still in touch with lots of ice friends. And regardless, I feel like I need to comment on it here.

Fall Up Lost Angel
Yeah, she's cute.
I hopped up to Lost Angel Road, up in the foothills outside Boulder, to hang out with her and her mom, Laurie, this weekend. Come up today, Laurie said on Saturday, because it's supposed to be windy tomorrow.
So we bundled up on what was really more of a winter day than a fall day and went for a short but lovely hike.

I was having a bad day, so what did I do? I colored.
I didn't realize until I was almost done that I was coloring. You know, classic coloring, like a kid would do. Here, kid, dry your tears, here're some crayons.
Okay, and it's a crappy piece of "art," but there are some nice elements to it, and it was just for fun, anyway. As far as what it is... I dunno, some vague semblance of water, rocks, grass, weird sky. I'd say they're not the colors I'd choose, but I'm pretty sure I chose them. To my credit, the room was pretty dark when I got started.
What do you do when you have a bad day?

I love Facebook.
It's annoying, too, but mainly I love it, and here are two reasons why, just from this week:
1) I wanted to say on our radio show on Tuesday that many (most?) scientific organizations suffered funding cuts for this coming year. It was meant to be a sort of "welcome to the next fiscal year, in the world of science" comment, and I knew UNAVCO has experienced a substantial cut in funding, and *assumed* that other orgs faced the same fate. But I didn't actually know. So, I put it out to Facebook. Crowdsourcing is the bomb. The responses from my sciency friends—a journalist, an NSF employee, a researcher and a field tech/engineer—showed the answer is more complicated than I could sum up in one statement, and I abandoned it. Lazy journalism or resourcefulness?
2) I saw a friend was listening to a bunch of Violent Femmes on Spotify (another great Internet tool) and shortly thereafter spotted my Cake CD (yep, still got some of those) on the floor of my room and thought yeah, I'm in the mood for something kind of quirky and fun. But I'm also in the mood for a female vocalist. !? Wait, what? Does that combination exist? Here's what I put out to Facebook:
Huh... are there any quirky / funny female bands out there? Or do all female bands take themselves seriously? I'm thinking Violent Femmes, Cake... is there not a market for quirky women, or am I just drawing a blank? Kimya Dawson is the only one who's coming to mind.
This is exactly the kind of query Facebookers love.
Here are the responses, in case you're curious:
The Ditty Bops
Lake Street Dive
Regina Spektor (esp. Soviet Kitsch or Songs
KT Tunsall (song: Ashes)
Now... I think most of, or many, of these are, say, spunky or sassy but not so sure about quirky and silly, or not taking themselves seriously. Some, though, yes, and all deserve a listen. I'm making my way through them on—yes—Spotify. Please, please, add to this list.
(My favorite comment, by the way, was "Cat power doesn't take herself too seriously....")
I might want to write a short piece on this, so by all means, if you have thoughts on this, please comment here, or e-mail me and rant, or find me on Facebook and rant, or whatever.

Christine Lavin ("is hilarious!! She has a song about an amoeba band in a mud puddle!")
Garfunkel and Oates
And, here's an article recommendation from my friend Nichole, which is worth clicking just for the pic with it. Awesome:
Me 'n' the Gov'mnt
So, we were told—I was told, or I heard somewhere along the line—that UNAVCO, where I'm working as a "temporary" employee these days, would not be affected by the government shutdown. Indeed, UNAVCO is not a government organization. But we are, like so many other organizations not represented in articles and infographics, funded by the government. Most of UNAVCO's funding comes from the National Science Foundation (NSF), with a much smaller chunk from NASA and an even smaller chunk from other sources. I don't know how the money distribution works, but apparently we don't just have a wad of cash from NSF to spend for the year (or the next five, which is what our grant is for). Perhaps we would have if it weren't at the beginning of the fiscal year. Either way, I'm cut off from hours until the government cranks on that lever and starts up the lights again.
I'm cut off because the decision was made (passive, because I don't know who made it and there's no reason to point fingers) to shut down funds to temporary employees, in addition to some other funding cuts. I was feeling maybe a little picked on (I mean, how much of their budget do I really take?) until an e-mail just came out reporting even more drastic measures: Salary cuts across the organization to keep UNAVCO running, at least for a bit. A salary cut that's not so much to cough at, for some. The org assures that this cut is in place "with the intent to restore retro pay when federal funds become accessible," which sounds just a little tenuous to me. Regardless, UNAVCO is taking one for the team. Whatever that means.
Also, the Antarctic season is in jeopardy. Right now is when everyone is heading south—or planning to. If you're not already down there... Well, hope you make it.
