Posted on June 20, 2013

Too much inside. Although we planned on being out in the kayaks again today, we wound up being inside at Dr. Becker’s place the entire time. We had a very hard time getting the conductivity and GPS data to sync up. We wanted to get them synced up via time, but unfortunately, after several hourts of format changing and excel table copying, we still weren’t able to get the data to play nice. Eventually, we were able to get a good join where all the data was visible.


Since we had 3x as many GPS points as conductivity points, we had to weed some out. In addition, we had to do some time corrections since we launched each device at a different time and (although we thought they were) they weren’t set to the same time.


Eventually, we were able to symbolize the data in a meaningful way. We found some likely seep locations even though the conductivity differences are minute. After spending hours indoors, we got a quick break to experiment with the GPR. We walked… very slowly… along the shoulder of the road. We tried to map the water table and found it easy in some places and difficult in others.


Take a look at the data we gathered and the GPR photos I took!
