Thule, Greenland – Day One

Arrived at Thule, Greenland after a 5 hr flight from Copenhagen.  It was pretty interesting seeing a long line of people all getting on a flight that was headed to a part of the world that usually has less than 600 people there at any given time.  Arrival was pretty straightforward, no jetway, no customs, no LCD screens telling you where to pick up your bag.  Just a few military personnel checking your documents to ensure that you have the approval from the Danish government and USAF to be on base.  First impression getting off the plane…it’s cold.  Not as cold as I expected it to be but it was just 90 degrees F when I left home a few days ago.  Today’s high was 39 degrees F.  Standing in the sun it’s not so bad but when the wind starts blowing it turns into a recipe for chapped lips and windburn.  Oh and did I mention the massive mosquitos here?  Not much wildlife in this part of the world but the mosquitos outnumbers the vertebrates probably a million to one.  They are also VERY aggressive; they even swarmed the trucks while we were driving around the base.  We were shown our living quarters, which were very nice, kind of reminded me of living in the dorms during undergrad.  There are individual rooms and a shared bathroom on each floor.  We toured the various sites that our collaborator Slava Epstein already pointed out as good sampling sites that vary in vegetation and proximity to water.  The land here is quite desolate, not much green, mostly moss and small shrubs growing.  Traditional trees are nonexistent but “ground trees” are actually common.  They are trees that grow outward on the grass and not upward.  The rest resembles pictures taken by the mars rover.  As the day goes by I noticed the sun was circling and I came to the realization that the typical artic summer was happening right in front of me.  The sun literally circles and will not go down until around September.  It was quite odd, getting in bed at midnight and seeing the sun still in the sky.  Tomorrow will be more interesting since we will be going further away from base to sample additional areas.

Thule, Greenland – Day Three

Day three started with me missing breakfast. It seems that folks around here only eat breakfast between 5am and 8am. Today was a very rough day for sampling.  About an hour drive to the area near the site, about a three-mile hike to one spot another half-mile hike to another spot followed by the three and a half mile hike back to the truck. We sampled “rich” soil and “rich” soil from a lake. These two sites were sampled and categorized as “rich” due to the abundance of vegetation around and near the sites. The area surrounding Thule is very desolate so I can imagine the plants have a hard enough time growing.  It would be very interesting to see what microbes are present in these two sites to allow such vegetation to grow; even more interesting to see how water affects the microbial population. Samples were frozen once we got back to the on site lab. A small portion was saturated with AllProtect to ensure preservation of RNA for transcriptomics analysis.

The day ended with a lecture from another NSF grant recipient to install a telescope on the Greenlandic ice cap. It was an interesting idea to coordinate radio imaging from other telescopes around the world to look at quantum singularities that were very far away. After speaking to some of the other scientists here I found out that our group, which includes myself and our collaborators Slava Epstein and Dawoon Jung, were the ONLY Microbiologists on the base. Everyone else was either a Geologist, Environmental Scientist, Astronomer, or Meteorologist. It was great to hear about everyone else’s projects.
