Weak end.

On Saturday, I received a bill in the mail from my University stating that I owed them several hundred dollars more than I thought. I had planned my semester according to the bill I received shortly after it began, but apparently that bill had not included certain fees associated to classes that I signed up with late and now also included late payment penalties. That put a real pinch on my wallet as I was banking on my tax return to cover my tuition costs. It no longer covers my tuition costs, and my trip to New Mexico is in jeopardy.

Tonight, at work, while I went over in my head the best way to maneuver a conversation regarding my need for time off to go to New Mexico in a way that wouldn’t threaten my job, I was interrupted by the man I sought to talk to. Before I had even asked him, he informed me that our already short staffed had become more short. The new guy, who has worked here for a total of a week and half, quit. He came to ask me to pick up the hours and effectively put the kaybash on my particpation in the trip to New Mexico.

I need money, and for that I need to work, and to work, I need to be at work. Needless to say, I am rather bummed out. I was really looking forward to going to New Mexico and experiencing geology like I have never done before. I will be jealous when they return.

Maybe the weather will be nice enough and I can head down to Southern Illinois and bask in some of Illinois more interesting geology.

Breathe in…

Here is a satellite view of McCarty’s flow in New Mexico. Some people from my Volcanology class and I are trying to spend spring break there doing rock nerd shit and trying to demonstrate an understanding of things we think we know. Really looking forward to it– camping and rocks that aren’t carbonates or sandstones.

I am done with my exams for a few weeks, very happy about that. Stratigraphy exam wasn’t nearly as bad it could’ve been; I was running out of time because my answers were so detailed, which usually is a good thing (in my head at least). I know I missed points on a few questions, but nothing that would sink the ship. Didn’t get Cycles exams back today like I thought I would, which is probably for the best. Had I got it back, I probably would’ve spent time obsessing over it instead of studying for Stratigraphy

Anyway, I get to spend my free time working on Physics and labs, and not obsessing over studying. Studying will not disappear completely, but hopefully be a constant that reduces the need for stress inducing super-study sessions.

Also, I got an e-mail today informing me that I would not be offered a position in Svalbard. A little disappointing, but the note was very will written and very complementary and came with a lot of information and advice based on what I wrote in my essay. That’s what I guessed anyway, if it was a mass, generic e-mail then it was very well written because it fooled me. So, it’s disappointing overall, but I don’t feel terrible about it. I will be doing something else this summer.

Decent Saturday…

The addendum to my Friday post… here are the videos that I mentioned.

They’re not as nice quality as I’d like (and I’m not sure where the purple tint comes from), but they’re decent enough. I wish I had thought to turn the stage more slowly while I was doing these though, particularly for this above video. You can see how the grains flash, but there are a lot of feldspar grains in that view that you can’t really see the extinction come and go because I’m moving too fast. I apologize.

Here is the large microcline under the thin section.

It definitely illustrates the idea behind extinctions much more clearly than my prior text or pictures. It’s a pretty neat deal.

Decent Friday

My friend lately. I still struggle when looking at thin sections, but it’s something I’ve enjoyed: building a visual vocabulary of the work on the microscale.

Here’s some pictures of some lithic arenites we’ve been studying. I took HD video of me rotating the stage on the microscope so I could demonstrate the types of things that you look for when looking at these under thin section, but I got lazy and I didn’t upload them. Essentially, you rotate the stage (where the slide sits) and you look for patterns of extinction (grains change color when rotated, usually dark to light) within grains. As the grain rotates, the light interacts with the crystallographic structure of the minerals resulting in a unique pattern.

I planned ahead very poorly when taking pictures obviously because there is only one grain in this picture that is showing off it’s extinction. In the middle top, you can see a grain that has both white and dark spaces that mix. That is a microcline grain that is halfway between it’s light and dark phase.

This next picture if of a gigantic microcline grain that showcases it’s extinction much more clearly and obviously.

When you see that cross hatched type of texture appear when rotating a slide, you know you have microcline. It’s pretty neat really.

I might upload those videos tomorrow to show it off a little better.

I filed my taxes today, my return will go to paying for school (to avoid late fees on my tuition payments) almost immediately once it’s deposited. Being poor sucks.

Science

I’m going to be 100% honest. I spent an hour and a half looking at this slide and others like it today in lab, and I still only know 70% of what’s going on here. I am terrible at this aspect of geology. Fortunately, I feel smart when I am sitting at a microscope.

I am going to meet with one of my professors this week about possible senior thesis stuff. Need to see if I am cut out for that path. Currently looking at the potential of doing something with reflection seismology. Who knows though, I have a few professors I want to bug about this topic (thesis, not reflection seismology).

Mixed

Well, today was a day of mixed feelings. I had my Structure and Physics exams today and I really thought I was better prepared for both of them. I probably did OK on my Structure exam, but my Physics exam was stupid (read: I was stupid). I tend to overthink physics a lot, and especially with kinematics I  work myself into these circular logic things. I might have squeaked by on that one, but there was a question on that exam that my answer just seemed way too off to be true (there were only 4 questions on it).

Given the opportunity to do today over, I would definitely seize upon that opportunity. I’m not happy with my exam performance.

I did get my Volcanology exam back though, and I am happy to report that I recieved an A on it. I didn’t think it was bad at all, but I’ve found myself to be enthralled with the subject. I hope  to get my Cycles exam back tomorrow, but as that class is rather populous, I expect an essay exam to take longer to grade than that.

Speaking of Volcanology however, I think I am settled upon my term paper (about damn time too, considering that it’s 15 pages and I need to get working on it). My paper, assuming nobody else has laid claim to the subject without my realizing it, will be on back-arc basin volcanism.

I figure that it’s a broad enough topic that filling 15 pages won’t be hard, and I think the tectonic settings and their implications for volcanism are really interesting.

Plans for this week: Taxes, finish last weeks labs, start this weeks labs, start studying for Stratigraphy and create some sort of schedule that allows this all to happen in the most stress-free, non-sleep robbing way.

A reprieve.

I missed a day of blogging. It is a slippery slope and it’s all downhill from here. I’m currently reading a paper on melt distributions below Mount St Helens inferred by electrical conductivity analysis.

After I returned home from school last evening, I promptly fell asleep and woke up today. I’m not typically the kind of person who skips sleep in lieu of my responsibilities. My mental dexterity is determined typically on the amount of sleep I got the night prior and my dietary choices. Sleep and diet took a back seat this week. Fortunately, I think I did well on both exams that necessitated this sleep deprivation.

I already spoke to my Volcanology exam, but my Global Cycles exam also went well. I came very close to running out of time as my answers were very long detailed and I always feel confident when that happens. I think most of my anxiety came from talking to my peers. When we begin talking about exams we create some sort of self-reinforcing panic cage that convinces me that-a.) The exam is a lot more important than it is and b.) I could never pass aforementioned exam.

Tonight and tomorrow I prepare for Structure and Physics exams on Monday.

Last night there was a meeting of the faculty members and undergrads to talk about undergraduate research opportunities within the department. There are a lot of interesting opportunities. I hope I can bug someone enough to let me in on some of it.

We’ve been talking about using seismic reflections to model magma chambers beneath volcanic zones in my Volcanology class, and one of my professors is doing seismic reflection analysis in Alaska, so I might try getting on board with that. More and more I’m thinking something mineralogical/structural geology related work. I feel like that is the best way to go to keep my academic and professional opportunities wide open.

It’s hard to think so much about the future right now as the present keeps slapping me in the face.

Here is a “funny” image I found today about how climate change “skeptics” view temperature and climate data vs. scientists and informed people.

It’s a Skeptical Science production.

Stereonets

I dislike them. Here is an awful picture of my last hour or so.

Lots of tracing paper and colored pencils.

Stereonets are way to visualize strike and dip in 3d space. They are quite literally the must useful little sphere you could ever encounter, but they are the most time consuming thing ever. I understand professors and educators want to know that their students could produce these kind of things by hand, but it’s hard to feel sympathetic when I can literally type in a few coordinates and have a complete stereonet in seconds with software like Stereonet (Windows) and OSXstereonet (Mac). [ATTN Geologists: These pieces of software are your best friends]

Just think; someday battery technology will be enough that we can disregard manual stereonets all together. It would be much easier to bring an iPad or other portable computing device with you in the field and have this information available in seconds.

Box of rocks.

One of my non-geologist friends, Davis, bestowed upon me a box of rocks as a gift today. He picked them up while his was in Maine on mysterious business and I must say, as a person who’s chosen educational career path is usually met with a quick change of subject or indifference, it was really cool to see a friend offer me a gift of something he thought I’d like.

I do like it, I’ve never seen a piece of green quartzite in person, and this one is part of an intrusion or has been intruded. It’s pretty neat.

Other neat things?

Locations that I have officially put my name in to do research this summer. Mostly of geomorphology and formation dating work, both of which I have zero experience, but both of which I really want to learn about and experience in the field. I plan on casting a wide net with this. I am planning to carpet bomb geology internship/research positions for summer as they become available.

I really don’t like sedimentary rocks…

I like sedimentary rocks. To a point.

I like the broad picture of sedimentary rocks. I understand the broad picture of sedimentary rocks. I like them because they’re a great look into the history of the earth. However, if you stick me in an environment where you give me a pile of sedimentary rocks and you ask me to identify them, and not just identify them, but REALLY identify them using modifiers like laminated and diamict, I will probably not like you much that day.

You know what sedimentary rocks I enjoy looking at and identifying? Sandstones. Everything else? Not so much. I will happily look at any variety of arenites you want to throw at me and I will drop acid on fossiliferous limestone samples all day, but when you ask me to classify this box of “shales” into siltstones, claystones, mudstones, etc… I quickly lose interest.

Here’s a picture of a lovely quartz arenite I found out in the woods one day.
