Sunday Hikes

Sundays are typically my one day off during the week.  To me, it seems like a waste to hang around camp  and sleep, so for the past two Sundays I've gone on hikes in and around the Brooks Range.  The first hike was to see some local aufeis before the seasons changed.  I went with Melissa, the kickass PolarTREC teacher who is on our research team for the first part of the summer.  For the second hike, I joined a bigger group headed to Atigun Falls, located just inside Arctic National Wildlife Refuge.

The Dalton Highway is under construction so we had plenty of time to stare at the pipeline while waiting for the pilot car.

Constructing Science

Over the last week, I've picked up a few skills I didn't expect to learn while out studying water flow paths in the Arctic.  I've spent much of my time constructing platforms for solar panels that power the electronic instruments we are deploying at our six field sites, as well as wiring and programming the electronics themselves.  Here are some of the steps involved:

Hauling scrap wood from the burn pile by the bonfire area.
Here, you can also see Toolik Lake still frozen, but the hillsides in the background are beginning to melt.

I learned to use a circular saw AND a table saw.

For my side of the project, the dataloggers (see four pictures down) are part of a thermocouple system, in which signals are sent down one wire to a temperature sensor, then come up a second wire with different material properties.  The signal is recorded by the datalogger and relates to temperature.  We have sensors at incremental depths underground in three wells, one inside the water track, one on the water track edge, and one outside the water track, at each of our six sites.  In this way, we can monitor how the temperature changes as the permafrost melt depth increases over the summer, and then freezes into the winter, re-thaws in the summer, etc.

I drilled a hole through a cooler to pull the wires that connect to the wells through.  The cooler houses the datalogger instrumentation and the battery, protecting them from snow and rain.

I had to strip all thirty wire pairs.  The wire is similar to thermostat wire.

Here's what I looked like for three hours.

Then I connected all the wires to the dataloggers.

Finally I hooked up the battery and the solar panel that will power it except through the sunless winter.  Hopefully it is working and recording data!  I'll go back and check soon.

Snow Days

I've arrived at Toolik Field Station, and really hit the ground running with fieldwork. My field season is divided into three parts, with lots of different tasks associated with each. There is the pre-snowmelt fieldwork, during snowmelt fieldwork, and post-snowmelt fieldwork. For at least one more day, it's the pre-snowmelt. However, the temperatures are soaring to the mid-40s during the day, so it's not going to last.  Here are some of the things we've been doing while we can:

The snow machines we use right now to get to our sites, which are right by the Alaska Pipeline.

A look at the snow profile.  Snow depth here is about 40 cm.

We built greenhouses to accelerate melt, but they are much better at acting as sails.

... even though they are pretty big.

Soon I'll post pictures from around the field station itself.  I haven't even really been anywhere except my weatherport, the cafeteria, and our lab yet, but hopefully soon!  

Alaska!

This summer, I'm heading up to northern Alaska for three months of fieldwork for a two-year NSF-funded project with Dr. Sarah Godsey, a new faculty member at Idaho State University. We are investigating how climate influences the hydrology and biogeochemistry of Arctic hillslopes. I plan on detailing my adventures, life at Toolik Research Station, and our project in greater detail as I learn more about it too!

Right now, I'm enjoying my first and last night in the aptly named, but surprisingly flat Fairbanks, where the weather is a balmy 61 F. Tomorrow morning, I will take a truck 350 miles north to Toolik Lake, where the field station is. I got some last minute gear and snacks for the 8-10 hour drive at the lovely Fred Meyer, Alaska's equivalent of Meijer or Wal-Mart.

Today I got to see most of the country, flying from Raleigh, NC to Washington, DC to Seattle, WA to Fairbanks, AK.  Here are some views from along the way:
