The mooring has a ballast weight at the bottom, then datalogger in a mooring frame attached to ballast, and a special cable with several sensors attached ("the sensor string") connected to a datalogger at lower end and to a float at top end. The datalogger had a pressure sensor which gave us the exact depth of the datalogger. To know exact depth levels for the sensors mounted on cable we measured distance between the pressure sensor and every sensor on the cable (with a ruler). This measured depths was added to a text label for each sensor. So the "Cond #241, +10.45" label means that there was a conductivity sensor with serial number 241 sitting 10.45 m above ("+" sign means "above") the pressure sensor mounted on the datalogger.
