On the 17th of November we began collecting ice samples. We intend to collect ice from the profile that we exposed after digging the vertical tunnel. The tunnel is approximately 2 m x 2 m and 5 m deep. Here are some pictures of the shaft and the different types of ice that we will collect.

The different layers of clean and dirty ice in the profile that we will sample. The sample profile is 4 m thick and consists of the following different layers, or facies. We are calling the three main faces in the profile clean glacier ice, stratified, and massive. The different facies, except the clean glacier ice are shown below. Each of these facies is ~ 1.5 m in our profile and they are oriented in the following order clean ice, stratified, massive (descending down the vertical shaft).
This section is an example of the stratified facies. The clean ice in this section is ~ 20 cm thick. The stratified facies contains numerous layers of clean and dirty ice and is approximately 1.5 m thick.
This section is an example of the massive facies. Ice in this section contains ~20-40% sediment (w/v). This section is ~ 1.4 m and lies below the stratified facies shown above.
