The result of using read.cm() on a current meter file holding measurements made with an
Interocean S4 device. See read.cm() for some general cautionary notes on reading such
files. Note that the salinities in this sample dataset are known to be incorrect, perhaps
owing to a lack of calibration of an old instrument that had not been used in a long time.
