The data set presented here is related to an article on revisiting Thorpe scale analysis in the Southern Ocean (submitted to GRL). The data enables the validation of a revised Thorpe scale analysis at 8 stations in the Southern Ocean: 1) 7 TurboMAP/CTD stations in Drake Passage in April 2009; 2) 1 TurboMAP/CTD station in the Kerguelen region in October 2011

1) TurboMAP (Turbulence Ocean Microstructure Acquisition Profiler) is a free-falling profiler and measures, among other parameters,
velocity shear (du/dz) at a rate of 256 samples per second, 256 Hz.
2) It was manufactured by Alec Electronics Company, Japan, which has been replaced by VMP, Canada
3) For the 2009 Drake Passage TurboMAP data, raw epsilon values are averaged in 5-m bins
4) For the 2011 Kerguelen TurboMAP data, raw epsilon values are averaged in 2-m bins

5) Raw CTD data from Sea-Bird Electronics SBE911plus are recorded in netCDF format, including information of the CTD fall speed,
a key parameter in the revised Thorpe scale analysis.
