Crossover Field Missive OR You Two-Timing So-And-So!

Notwithstanding the last month's epic publishing rate, I have been mostly absent over the past 6 months. In part, I blame this on a dull field season - I was away from my desk a lot, but with nothing particularly interesting to report. But I have also been drafted to write for the grad student blog, BioDiverse Perspectives, which is stealing some of my blogging juices(1). 

Well, the field season is almost done, and what have I to show for it? Not as much as I had hoped, which shouldn't come as a surprise to anyone. But, here are a few notes to provide insight into what I did do:

Numero Uno:

Season opener: I topped 100,000 miles in my trusty field buggy, the RV Grason (Figure 1). It was poetic how I rolled from 99,999 to 100,000 just as I passed the sign entering Anacortes on one of my first days of field work.

Figure 1. RV Grason.  What a trooper! This is from an earlier excursion
where my car ferried 2 sea kayaks to Willapa Bay.

Section B:

This is a post I wrote for BioDiverse Perspectives, if you haven't already seen it, on my field work this year. It gives you a bit o' flave of what the ol' 9 - 5 is like. I'll be appearing there on an ongoing basis in a (only slightly) more serious role in the coming months (years?).

Item the Third:

I listened to a slew of audiobooks on my drive back and forth to the marine lab. Lets see: And the Mountains Echoed (Khalid Hosseini), Still Alice (Lisa Genova), Bossypants (Tina Fey), Gone Girl (Gillian Flynn), The Virgin Suicides, The Marriage Plot, & Middlesex (yeah, Jeffrey Eugenides kick)(2). I didn't get through as many as last year, when I listened to all 5 Song of Ice and Fire books, but I feel like I have made something of my life.

Part IV:

Ok I did do some actual work too. I ran a study in Willapa Bay where I tied snails to rebar with fishing line (Figure 2). Why? Because I am a scientist. 

Figure 2.  Everyone hanging in there? Ha! This is what it looks like when I do science,
it's a real mess. Here I am untangling 30 snails tied with fishing line and trying
to see if they are still alive and/or damaged. Thanks Ryan for the photo!

Ok, fine. I am trying to see whether there were any predators that eat these invasive snails (here: Batillaria attramentaria). So I tie them to rebar and set them out in the mud along an elevation gradient (shallow to deep). The intertidal dogma is that competitors or predators control how deep an organism can live(3). If the deeper rebar snails get eaten more than the shallow rebar snails, that is good evidence that this is indeed the case. I don't want to spoil what will undoubtedly be another thrilling piece of scientific literature, but indeed, in Willapa Bay, crabs eat snails in the deep. Just to be sure, we trapped some crabs (Figure 3).

Figure 3.  Woah! Thats a trapload of crabs!
Witness: Metacarcinus magister (Dungeness crab)

And now, for the exciting conclusion:

And all that driving was for some reason, right? I sure hope so, says the planet choking on my C02. Up at the marine lab, I was conducting mad-scientist research on snails. In my current experiment, and hopefully the last one for the season, I am looking at behavior of a native snail (whaaaaa?!) Littorina sitkana and exploring their reaction to predation cues, much in the line of previous work with invasive snails. So far, it is my scientific opinion that these snails is crazy (Figure 4).

Figure 4. Girls on film! No, not that. Snakes on a plane? Nope, not that either.
It's Littorines on Slides! I grew diatoms on glass microscope slides to see how much the
snails will eat when they smell scary crabs around. These snails had a hunger.

So, there you go, that's what I did on my summer snailcation. Can't wait until the next one! Actually, I can. I can totally wait until then, because, really, that's enough of snails for one year. Time to sit in front of my computer with a cup of coffee for 6 months...aaaah.

Occupational Hazards OR The Massacre of a Manicure

Field work, she is a cruel mistress. For what she gives in snails, she takes back two-fold in personal injury. The system is just primed for misery: if you do it like me, you spend your winters sitting at the computer and/or listening to people talk for hours on end (1). Muscles atrophy, and I can hear a soft "click" every time a ubiquitin is attached to my muscle proteins, targeting them for degradation. Callouses are resorbed, melanin dispersed, and the smell of what could politely be called "ocean musk" finally airs out of my car upholstery.  Then, come April or so, I walk out of my office, blinking, and it's a 0 - 60 transition. 

GO! RUN! CARRY! LIFT! THROW! HOLD AWKWARD POSITIONS FOR AN EXTENDED PERIOD OF TIME! 

In celebration of the upcoming start of the London Olympics, I am proposing three new events, at which I would excel (as long as the olympics were at the end of the field season):

1. 300m Mudflat Traverse: Sprint the length of your transect at top speed! Fight the mudsuck as your feet sink somewhere between 1-8" with every step, if you're lucky. This event includes 2-3 return trip/s, depending on how many things you forgot on shore.  Bonus points for outrunning the return tide.  

2. The 300m Rebar Portage: Carry 10 3' sections of 1/2" rebar with only your wimpy left hand down the same transect (does not have to be completed at a sprint, in fact, that could be dangerous). Alternate technique: carry 25 sections of 1/2" rebar with two hands, but relinquish the ability to disloge your boots from the mud, because your hands are full - it's your call.

3. The Crouch-and-Count Endurance Trials: This event is the more challenging cousin to the kneel-and-count, which is what the amateurs without leaks in the knees of their boots participate in. This is also my least favorite event. Count all the snails in a 1m space, and DON'T LOSE COUNT, or you'll have to start all over! Repeat this 40-50 times ... a day ... throughout the summer. A tremendous way to put your love of science and supposed fasciation with mollusks to the test. Scored based on accuracy, speed, and penalized for the number of times you change position.

My whole body hates the beginning of the field season, for which it has been so poorly primed. Hands suffer the most. I don't wear gloves because I can't feel what I'm doing. So the constant immersion in 50 degree saltwater (the Pacific doesn't really warm up, people, though on warm days the mud does mitigate the situation) softens my skin, and the oysters finish the job, slicing up my fingers, which, thanks to the winter hiatus, resemble 10 individual servings of Polly-O String Cheese in, color, toughness, and grip strength. For the first few weeks, my hands cramp constantly. The mud gets so far under my fingernails, it stays there until November - not for lack of scrubbing, though, mind you! 

My fingernails themselves take the most abuse. They are my most important tools in field work (3), but trying to use them while they are wet and soft shapes them into a complex and rugged topography. The surface is ground to a fine matte finish by the sediment. For this reason, I typically restrict the distribution of polish on my body to my toes. But this summer, I was a bridesmaid in my friend Karen's wedding. Sometimes I try to look like a grown up, and to match Karen's wedding (WITNESS her craftiness!), we all got our nails did like fancy ladies. Here is a chronicle of what happens to a manicure when you return to work on the mudflats. I apologize in advance for the poor quality images.

T = 0

Figure 1. Nails on before my first day of returning to work. Oooh, so fancy! 

Wedding was Saturday night. This (Figure 1) is Monday morning. The Disney Princess  band-aid (Jasmine?) on the left middle finger was actually preventative. I cut the skin on the inside of that joint, down to the tendons, incidentally, with brand new tin snips the week before, and wanted to protect the healing cut (2). 

T = 1

Figure 2. Hands post-day one. Decidedly less fancy.

By the end of day one (Figure 2), on which I was actually working on carpentry, I have gained a net of one band aid (I evidently tore the skin on my right pinkie pretty badly by scraping it on a plastic valve and have no idea why that index finger was bleeding, but was able to remove the one from the left middle finger) and you'll notice the polish hasn't fared very well.  It starts receding from along the edges and the cuticles, just look at it go!

T = 2

Figure 3.  Wear and tear on fingernails after two days of being a marine biologist.  

On day 2, I was out in the mud, counting snails, and I had so many cuts, I thought it wise to wear a really thin glove on my right hand. The Michael Jackson technique worked, and the nails on my right hand fared pretty well, but we are seeing definite recession of the polish on the left (Figure 3).  This is also evidenced by the dirt under left but not right fingernails.  The only reason I am wearing fewer band-aids, however, is that the glove sucked one off.  

T = 3

Figure 4.  Cleaned hands after Day 3. Note also, healing gash on right pinkie.

I wasn't able to favor my right hand with a cushy glove on day, three, and it shows (Figure 4).  There goes the polish on those fingers as well.   

T = 4

Figure 5.  Cleaned hands after day 4.  My nails really look like crap.

Day 4 was more of the same (Figure 5).  At this point I thought about doing image analysis and mapping the loss of area of painted nail over time.  But I got lazy.  If my pictures were better, it wouldn't be too hard.  

Well at this point I felt badly every time I looked at my massacred manicure, so I took off the polish entirely.

T > 5

Figure 6. Still residual dirt under my nails, but devoid of polish.

Back to plain, old, Emily hands (Figure 6).  But slightly stronger and tougher.  

Ok, I'm sick of looking at pictures of my beat-up hands.
