We just finished our first successful profiling mission today. We performed profiling at 19 points. The approximate length of the mission was 2.4 km. The mission was mostly uneventful. We saw some interesting microbial growth on lake bottom near the shore and also some iron leached out from sediments. John extracted some data from yesterday’s profile which shows some very interesting characteristics (I will post some of John’s plots and a map soon). We also ran down the batteries and now have a better characterization of the tripping behavior – this should help us plan future missions better. It’s been a very long day. We have worked non-stop for 14 hours. I am exhausted but elated. Below are some pictures.
