A study of Mean Sea Level (MSL) determination in the Aegean Sea is carried
out. First, MSL values have been computed at a number of tide gauge station
s. Then, Sea Surface Heights (SSHs) have been determined based on GEOSAT al
timeter data of Geodetic Mission (GM). The computed SSHs were fitted to the
tide gauge MSL values using a 4-parameters model. The best fitting agreeme
nt reached the level of 5cm, when GPM98A geopotential model was used as a r
eference surface. (C) 2000 Elsevier Science Ltd. All rights reserved.
