Science activity summary for Spaceward Bound 2008 Arctic

Saturday 26 July 2008
We left Resolute Bay in a Twin Otter for the 2 hour flight to the McGill Arctic Reseach Statioin on Axel Heiberg Island. Our Station is on the shore of Colour Lake at N79.41550 W90.75120 with an elevation of 180m.

We ate lunch and had our first planning meeting with Wayne Pollard of McGill University. After lunch we hiked down to the active springs at the base of Gypsum Hill. We took a water sample from one of the most studied of the spring sites here:
Little Black Pond. Located at N79.40409 W90.73309 elevation 19m. See photo. Note the gas bubbles coming up in the water.

We hiked along the White Glacier. Our destination was a site that may be a dry relic of a former spring. We found the site at N79.44386 W90.70168 elevation 343m. Samples collected tested positive for carbonate here at the Station.

Today we hiked to the active springs. The group from the lower camp (about 7 km away) came to the springs and we worked there together this morning. We measured temperature. As previous data indicated springs located without 10 m of each other have temperatures that differ by 5ÂșC. Tomorrow the lower camp team will bring their shallow seismic equipment and we will try to investigate the subsurface structure of the springs to understand how such close-by springs can have different temperatures.

Tuesday 29 July 2008
Our plan is to go back to the active springs at the base of Gypsum Hill and do the seismic work.
