Nov 14 – Traveling east

We spent the morning looking at data from yesterday and trying to debug the communications failure problem. We had some ideas but we were not sure what the exact problem was. The mission for the day involved  traveling to the narrows – the part of lake that connects west lobe to the east lobe. The bot swam about 1.5 km to reach the far east – this is the farthest the bot had ever been. Much remains
unknown about this part of the lake and we were very excited to see the visualizations from the sonars on the bot. We might go there again later for getting more data.
While returning back, we had the same comms failure again. In a flash of inspiration, I was able to figure out what the problem was – a process that had memory leaks and was slowly eating up RAM till 100% was used.
Midway through the mission, it started to snow and Vickie and Bill had a tough time outdoors. It is fairly rare to snow in the dry valleys, so I was very excited. At the end of the day, Bill showed me how to track the robot using the radio beacon. Overall, this was a very good day for us and we have decided to take the day off tomorrow.

A map of lake Bonney showing the profiling points. The points that we have finished are shown in green. Today we went to the point farthest east (D21) on the grid. This point is at the far east of West lobe and at the start of "the narrows" - the narrow channel of water connecting the west lobe to the east lobe.

Bill and Vickie at the end of the day. They were out all day tracking the robot and marking the exact location at whihc it profiled. It snowed half the day making their task difficult.

The first snowfall I have ever seen.
