Science Activity Update: July 29-31

Tuesday 29 July 2008
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

In the morning we plan to do to the lower camp and test the Max 5R rover. If possible we will also hike to the Colour Peak Springs.

Going to another relic springs site, revisiting the relic spring site we visited on Sunday.
