Concord has been recording depth soundings and type of bottom at times during their voyages, currents and depth of water at anchorage etc. The latter especially at anchorage in the Min River near Fuzhou. It seemed to me that the depth soundings and type of bottom during transit might have been some kind of survey because there would be lots of soundings for a day or two when in transit around Korea or China, and then nothing for days. Usually, when they anchor, they record the bottom type and depth. They also record, every day when in port, how much food and what type they are buying for the crew; things like, "114 lbs of bread 128 1/2 lbs of fresh beef and vegetables". Not very interesting to me, but maybe to a dietician or someone else in the health sciences.
