We performed two more glacier missions in the past two days and have explored most of the glacier face. Bill and I had been working on extracting and plotting the Delta T data from the past few days to see how the glacier looks like. The data from each mission consists of approximately 25 million (x,y,z) points that correspond to the sonar returns. Bill plotted up the points in 2D, and we used this to plan today’s glacier mission so that we would cover parts of the glacier face we had missed in the previous missions.
Today’s mission consisted of scanning the entire glacier face with the Delta T – we had the robot facing the glacier wall at all times while moving sideways. This was a relaxed mission for us since we ran the entire mission as an automated script and all we had to do was sit back and watch the data and the visualizers.
Bill plotted the data from all the missions to get an amazing view of the glacier face and lake bottom near the glacier.
We also took a picture of lake bottom with our profiler camera.
