摘要

Abstract

The effects of surface waves and ship heave-and-roll on CTD data are discussed. The heave-and-roll produces spurious step-like structures in the CTD data. Derivation of a formula for calculating the probe's fall speed is discussed. Several current techniques for CTD sensor lag correction are analyzed and compared. It is shown the lag correction procedure presented here

which is based on the Giles-McDougall technique

can be employed to treat CTD data from regions with slow or fast T-S variations

for instance

in strong seasonal thermocline. False salinity spikes or humps in data corrected with this procedure are significantly reduced.
