\item[Level 0 (L0)]: this is the level closest to the original measurements, as it is designed to contain exactly the same data as the raw files provided by the instruments. The goal is to deliver a single, standardised netCDF file, instead of one or several files in a platform-dependent format.
\item[Level 1 (L1)]: in this level, additional variables are derived from the existing ones (e.g., salinity, potential temperature). The attributes corresponding to each variable are stored in the netCDF file, with details of any modifications. Unit conversion are also applied if necessary.
\item[Level 1 corrected (L1\_corr)]: this level is only available for the CTD: a corrective factor is obtained by a linear regression between the salinity measured by the CTD and that measured by the salinometer. The files corresponding to that processing levels contain new variables of conductivity and salinity to which the correction was applied. Additional metadata regarding the correction are also provided in the file.
-\item[Level 2 (L2)]: this level is only available for the gliders. It consists of regular, homogeneous and instantaneous profiles obtained by interpolating the L1 data. In other words, 3-dimensional trajectories are transformed into a set of instantaneous, homogeneous, regular profiles.
-For the spatial and temporal coordinates: the new coordinates of the profiles are computed as the mean values of the cast readings. For the variables: a binning is performed, taking the mean values of readings in depth intervals centered at selected depth levels. By default, the vertical resolution (or bin size) is set to 1 meter.

The glider data require a specific processing to ingest and convert the raw data files produced by the coastal and deep units. This is done within a toolbox designed for this purpose and extensively described in \citet{TROUPIN16}, the capabilities of which includes metadata aggregation, data download, advanced data processing and the generation of data products and figures. Of particular interest is the application of a thermal-lag correction for un-pumped Sea-Bird CTD sensors \citep{GARAU11}, which improves the quality of the glider data.

-This type of current measurements requires a careful processing in order to get meaningful velocities from the raw signal, hence it is relevant to have a quality flag (QF) assigned to each measurement. The quality checks applied for this platform were adapted from the quality control (QC hereinafter) relative to the ADCP mounted on a mooring.
+The vessel's velocity is one or two order or magnitudes greater than the currents that have to be measured, hence this type of current measurements requires a careful processing in order to get meaningful velocities from the raw signal. The QC procedure for the VM-ADCP is complex as it involves tests on more than 40 technical and geophysical variables. The different tests are based on the technical reports of \citet{COWLEY2009} and \citet{BENDER2009}, which aim primarily at ADCP mounted on moorings.
