• CTD data

One file per station (Pressure ,Depth, Temperature, Salinity, Oxygen).
Metadata in each file.

OCEAN CURRENT DATA:

Acquired with RDI Acoustic Doppler Current (ADCP) Profilers. 

• Ship ADCP (SADCP):

Acquisition with VmDAS software. Processed from the .STA files.
Alignments were corrected with a dedicated cross trajectory on the shelf.  
SADCP OS38: metadata in txt file. Used to constrain LADCP final data and the transports calculated by an inverse model.
SADCP OS150: metadata in txt file. OS150 was installed in the oceano well. It was stopped during stations to avoid interferences with the down-looking LADCP (also at 150kHz).

• LADCP stations:

Processed with A.Thurnherr LDEA software v.IX_14.
Metadata in the files.
Matlab and text files provided.
