Today was our first day of sampling in the field. It was a gorgeous day for Churchill in February...only -20 and no wind. I layered up in my six layers plus heat packs, goggles, balaclava and Arctic pants, loaded all the research equipment and data sheets and headed out to get in the "sled." Somehow when they told me we would be riding in wooden boxes pulled behind the back of a snowmobile I didn't really envision a WOODEN BOX TOWED BEHIND A SNOWMOBILE! :) That is exactly what it was! Four of us piled into each BOX, claimed a cushion if we could, and off we went. Ow...
We were divided into teams of three at each sampling site where we had to dig a pit and investigate the various layers of snow. For each layer we had to measure depth, temperature, density and compressibility, as well as analyze the type of snow particles and their size within each layer. Then we had to take 11 core samples, noting depth and weight of the snow core, and bringing three of the samples back to the lab to measure conductivity and pH. We then moved to another location within the site and repeated the process. The photo is of our second snow pit, with thermometers placed at 5cm intervals in the layers. Our location today was a Borrow Pit, a site that was excavated at one point. One of the things we are looking at there is the effects of anthropogenic changes on an ecosystem. What does that mean?
Tomorrow our plan is to go to two different sites, where we will go through all the above steps again... That means I will take 44 core samples tomorrow!!! No complaining about how many times you have to go to your field research sites! :)
On Thursday, you must go to Tutorial in Mr. Wilson's room, P-38. This is mandatory! Your blog challenge due Wednesday is as follows:
1. Define what "anthropogenic changes on an ecosystem" means and give one example.
2. Come up with two GREAT questions for me, Dr. Pete, or my Shell Inc. teammates. On Thursday you will be able to speak to me LIVE (I know how much you miss me!) and I want some good questions from you! The video conference is an excellent opportunity for you to earn some extra credit if you do more than the required showing up! ;)
This blog challenge should be turned in to Ms. Duffy AND sent to me by clicking "comment."
Talk to you soon...
