Today we meet with the group from the lower camp to do a seismic study of the Gypsum Springs area. A string of geophones were placed on the ground and then a seismic disturbance was generated by hitting a target with a sledge hammer. The geophones pick up the sound wave as it bounces around in the ground. From this we hope to be able to learn something about the subsurface structure of the springs.
We also dug a soil pit to the ice-cemented layer to sample bacteria living there. We will compare them with bacteria living in this zone in Antarctica. We chose a site at N79.40451 W90.78466 elevation 116 m. The site is along the ATV path connecting the upper and lower camps. Depth to permafrost was 72 cm.
Planning ahead
