Medspiration external interfaces. In addition, this will give access to some other data
sources such as Argo or the in situ data collected over the Mediterranean sea during
the MFSTEP experiment (from September 2004 for 6 months).

3. SST measurements : It can observed from the above table that selecting only
SST1m measurements will lead to ignore many other data sources. It is suggested to
relax this constraint down to 5 m (the closer measurement to the 1 m depth will be
selected anyway for each profile) which could allow to consider also the float
measurements which quality may be valuable for the MDB.
4. The meteorological data are currently not available within the CORIOLIS data. It was
agreed with CORIOLIS head that they will be collected from the GTS by the
CORIOLIS staff (when simultaneously available with a SST measurement) and
