Sonmicat: Sea Level Observation System of Catalonia

Abstract:

SONMICAT is the integrated sea level observation system of Catalonia.
SONMICAT aims at providing high-quality continous measurements of sea- and
land levels at the Catalan coast from tide gauges (relative sea levels) and
from modern geodetic techniques (vertical land motion and absolute sea
levels) for studies on long-term sea level trends, but also the calibration
of satellite altimeters, for instance. This synergy is indeed the only way
to get a clear and unambigous picture of what is actually going on at the
coast of Catalonia.

SONMICAT aims to be:

- an integrated sea level monitoring system (different types of data, sources, time and space scales), - a sea level information system handling the data measured by
 different observation networks,
 - a local/regional component of international sea level observing

systems (GLOSS, ESEAS, etc.), and - a local/regional interface for related European and Global projects

and databases (PSML, TIGA, etc.)

There is a gap of sea level data (GLOSS, PSML, TIGA) in the coast of
Catalonia, although several groups and institutions have started to do some
work. SONMICAT will fill it. Up to now, the system has started at
l'Estartit and Barcelona harbours.

A description of the actual SONMICAT infraestructure and campaigns -
especially at Barcelona harbour - are presented. In June 2014, an airborne LiDAR campaign has been carrying on in Barcelona following two ICESat tracks.

First results of the airborne survey will also be presented.
