CHORDS: A New Temperature or Sound Speed Profile Thinning Algorithm

摘要

A new sound speed and temperature profile thinning algorithm especially designed for use with high vertical resolution (1 meter) conductivity-temperature-depth (CTD) or expendable bathythermograph (XBT) digital data is described. The thinning operation can be halted once the desired number of output points is obtained or alternatively when a user-supplied tolerance value is reached. The new algorithm has the advantage of scanning the entire profile during each iteration. As a result, unlike other thinning algorithms examined, profile curvature at depth is retained. (Author)
