THE LAB 10.24.12


Hello All! Sorry for the delay in adding posts - I caught some horrible version of  "The Crud" as they call it here and was dreadfully ill for a week or two. It seems that people just pass around diseases here, as you might expect, in close living quarters. I'm now back on my feet and will attempt to catch up on splashing pictures across the internet for your enjoyment.

Here are a few shots of the inside of our lab, as well as from within the larger Crary Building (the main science building here), where we all conduct experiments, hold animals and samples and prepare for field work at all hours of the day and night.

Below are two of four water baths - all held at different temperatures ranging from nearly -2C to 10 C. This is an example of one of the ways in which a heat shock experiment may be conducted. Here, we've obtained liver cells from local fish species and are exposing them to a range of temperatures and time points. The cells have been processed in a manner that allows them to float freely (not attached to one another as you would find within an organ or tissue matrix) in a solution that mimics the nutrients and chemistry normally available within the body of the animal. These cells float within the tubes you see within their faux medium, which in turn, float in the water baths allowing them specific temperature exposure and regulation. These samples will be shipped home for further processing where we'll try to piece together what exactly is happening within the cells upon heat stress exposure. From there, we can extrapolate further to relate environmental and biomedical consequences for both humans and animals. 


Here are the other two water baths (total of four):

It looks so simple, but it takes quite a bit of work and many hours to get to this point and many, many hours afterwards in order to obtain the information we are looking for. 






The water bath says 8.9 C but it was really just 8.0 C. Tricky, tricky.







When the samples above have reached their destination time point, they are processed and transferred to these vials and stored in the fridge until we can ship them back to our lab at home.



Tiny boxes, with tiny samples that are oh-so-precious, potentially containing large volumes of data waiting to be deciphered.




Chemical shelf shot. Everything must be pre-ordered, specially shipped and stored here until we arrive to make an array of solutions using these ingredients specific to our cause.

More samples at different temperatures.

As I wander to other parts of Crary, I notice this particular example of how standards for certain things may slip as the season drags on and work becomes exhausting and places to   put things seem to become less available. This is an orange in a dirty shoe with dirty socks in the hall which someone will     surely thoroughly enjoy in the near future.                                             
         

Ghosts appear in the halls and
t
iny grave yards pop up - nothing
spectacular, but we do what we can
to create a sense of connection with
time and space back home where
holidays are celebrated and missed.
 
















And Crary Lab becomes SCRARY:

Below | On another note, this was a fairly recently recovered lost artifact from a data collecting expedition in 1958. It was used to scoop up samples from the sea floor and was lost in the process at one point, only to be rediscovered and set out for display years later (article on right).














BELOW | Here are some fish traps stored outside. We left one submerged at the Jetty
with more hot dog bait and it came up EMPTY - except 
for this amazingly colored starfish on the bottom right...
...which is actually a plastic toy that the divers placed in our trap as a joke - because clearly, they thought it was hilarious that we hadn't caught a single fish. No sympathy at all for our situation.

BACK TO INACCESSIBLE ISLAND 10.23.12


We pass some islands poking out of the frozen sea while en route - once again to Inaccessible Island for the day.









Below | Ice features through a dirty Pisten Bully window.









The boss riding along in style.

Below | At the red flags you can see a "bridge" installed (some wood slabs) to help us drive over this obvious ice crack safely. There are a few of these along the way and they've been extremely helpful this year; they save us a tremendous amount of time and effort. If they were not in place we'd need to stop the vehicle, shovel through the snow, manually drill through the ice to hit the sea water in order to measure the ice depth and to determine if there is an acceptable distance to cross the crack with the vehicle on the way there AND back at EACH crack - and there are several. It's a good amount of work and can cut into travel time dramatically














Jiffy drilled ice hole after a few days...




New hole!

Beautiful dense Sea Ice:


Fishin' Fishin'

I catch one...


One 'T. Bernie' as we fondly call this type of fish:

InaccessibleIsland from another angle in all her glory:

Seal spotting! A Weddell - who has spotted us in return. 




Below | This is the hole the seal came up through - which is pretty amazing - just large enough to haul itself out and onto the snow.

You can see the bit of blood where the seal must have scraped itself on the ice on it's way up:














CUTE!





The above images are pretty zoomed in - but in reality we stay far way from the animal so as to not disturb or disrupt:

We have fish to get home

 And we are on our way back to McMurdo Station.

10.19.12 LIBRARY, POP-UP TENT AND APPLE #3


Back in the Pisten Bully we head over to an "Apple" - which is a sort of hut around the corner near Scott Base where the New Zealanders reside. That's me below in the passenger seat wearing my circa 1993 style ski glasses so that I'm not blinded by the snow. 

Here is Scott Base - it's much smaller than McMurdo. The Americans and Kiwis work together often and share resources as necessary:

It was a very windy - but brilliant day as you can see here. We park, unload and shuffle inside.

Apple #3 here has been placed over a dive hole that's been pre-drilled. Just as before, we use the designated dive hole for fishing.

With most of our team in this shot you get a reference for scale here. The door is quite awkward and wants to slam shut with the wind.


Here are the 3 wind turbines placed above McMurdo - which apparently make up the world's southernmost wind farm - see article: http://cleantechnica.com/2010/01/16/worlds-southernmost-wind-farm-now-feeding-antarctic-grid/

The clouds are a strange texture here:

We head inside of the Apple which blocks you from the wind - but does not have a constant source of heat running as some of the more substantial huts (posted earlier) do. 


Given the fact that we are fishing and coming into contact with the freezing cold water, ice and super cold fish - it's a strong preference to have some way to quickly warm your fingers back up if possible. I'm proud to say that I got this bad boy below started - which wasn't actually very straight forward.


Warmth!

There is no plastic tube sock above the hole with a fan to blow the warm air towards the opening and as a result it seems to want to ice over immediately after we try to clear it. But again, it's such a lovely color...


Brad standing in the Apple fishing.

We had no luck here - apparently there is a nearby seal that also uses this hole to come up for air. Also, seals eat fish... The divers let us know that the few that are still below - smartly, seem to be hiding. 

The ceiling of the apple:

A very McMurdo set of instructions - Mac Ops stands for McMurdo Operations - the radio communications center. 

The door from the inside:

Just in case...

Icy apple window:

This was the flagged route we drove down to get here - it's hard to see but just to the right of the very last flag - is actually a C-17 plane landing I believe - on the sea ice with more goods and people to offload.




Heading back - fishless - but happy.


A final view of the kiwi Scott Base. Americans can go to the store to purchase things - but only are allowed on the rest of the base when specifically invited. They hold "American Night" frequently.

To the library...

We decide to set up our pop-up ice tent in the library.


Then I give a speech. 




A very Antarctic selection of books:
