Dec 2 – Profiling the narrows again

John thought that it would be a good idea to profile the narrows again so that he could see the variation in properties with respect to time. We profiled the narrows again yesterday. This time, the mission seemed very easy and went very smoothly. Below is a plot of the narrows (from Bill) using the data from the previous run.

Plot of the narrows from sonar data. The narrows refers to the narrow channel that connects the east lobe to the west lobe. In this view, we are looking from the east side. The points are color coded, so the green points are at a lesser depth than the blue ones. About 100 years back (1903), Scott's team travelled through this region and took various measurements. This channel was much narrower back then. (Sorry no numbers, Peter mentioned their values, but I don't remember them anymore).
