This data publication provides the dataset of turbulent kinetic energy dissipation rates sampled during the Ovide A25 2008 cruise. The dataset was gathered with a deep autonomous Vertical Microstructure Profiler (VMP-6000). A raw and a processed version are available as tar files. The raw data are available as a tar file containing the thirthy raw files (extension .p) with all internally recorded parameters. Raw data files can be processed using the ODAS software, which can be downloaded from the manufacturer on request (website at: https://rocklandscientific.com). The processed version is available as a tar file containing thirthy NetCDF files. Each NetCDF file contains the dissipation rate profile, the time (UTC) of the profile start, the geographical position (deployment of the VMP or mooring position), and the mean pressure for each dissipation rate estimate (two estimates at each pressure level from the two shear sensors). Each dissipation rate comes with a quality control matrix QC (14 x 4) that characterizes how the associated mean shear spectrum fitted the expected theoretical Nasmyth spectrum. Reference for data processing: The raw '*.p' files contain all the necessary information (with appropriate calibration coefficients when needed) to transform the raw data into physical units using the ODAS software. The user is referred to the software documentation to get more details on the data processing of those raw files (see https://rocklandscientific.com). Shear data were processed following the processing flow chart of the Atomix SCOR Working Group 160 (https://wiki.app.uib.no/atomix/index.php?title=Flow_chart_for_shear_probes).
