Well we just got back from a successful day out on the ice. We went to the same GPS location as in 2010 when we deployed the Ice Mass Balance Buoy, to install a new IMB again this year, this time for the Cold Regions Research and Engineering Laboratory. I’m hoping I’ll be able to get a plot of the data to show you some results.

IMBs are very valuable tools for monitoring the ice as it melts in the summer and freezes up in the winter (assuming the floe lasts the summer).
We had another spectacular sunny day, though some clouds rolled in at the end of our day. The weather was maybe -5 to -10 Celsius but it felt so nice and warm. My face is a bit sunburnt again (nothing serious though).

In addition to deploying the IMB, we performed the usual measurements of taking ice cores, measuring ice thickness with a drill, measuring snow depth, taking ground EM measurements with two different units.
I also had a chance to test out my camera again below the ice. I also created a very shorted time-lapse movie from some pictures I took while we set up the IMB. Below are the two movies. Sorry for the poor quality but I've reduced my footage to some awefully small sizes in order to be able to show them to you while I am still in the field.
Tomorrow I plan to do a longer time-lapse sequence as Alec and I doing the drilling and EM31 transect. We will revisit our site from today to take 1 more core, and then we are off to find a first year ice floe for more cores/EM and drilling.
Well that is all I’ll write about today. More tomorrow.
Cheers
