Abstract:

The steric component of Mediterranean sea level as
obtained from different hydrographic gridded products is
compared for the last decades. The widely used
MEDATLAS2, ENACT/ENSEMBLES, ISHIIV6.7, and
ISHIIV6.12 databases show large discrepancies, mainly
derived from the halosteric component. The validation of
the mass component against gravimetry data suggests that
ENACT is slightly more accurate than the other data sets.
Concerning long-term trends, the thermosteric component
computed down to the bottom for the period 1960–2000
ranges from 0.06 ± 0.12 to 0.09 ± 0.16 mm/yr. Halosteric
trends are negative for all products, but the magnitude and
spatial patterns provided by the four products are
statistically inconsistent among them. This prevents giving
consistent figures for the overall steric term and mass term.
Conversely, the trend of the freshwater content of the
Mediterranean basin can be estimated more accurately,
ranging from 1.0 to 1.3 mm/yr for the period 1960–2000.
