On the best of the geoid and of the sea surface topography in the Mediterranean area

Objective



The aim of this work is to study the problems related to geoid and sea surface topography estimation in closed seas. The area on which these problems will be studied will be the
Mediterranean Sea.
The initial part of the project will be devoted to collect data to be utilized in such an investigation. In particular an update gravimetric and altimetric data sets will be formed. The
altimetric data are the ones from Seasat and Geosat altimetric missions; ERS1 data will be included if avaliable. The gravity data set still exists (althoug with some lack data area);
however, data validation and standardization are needed.
If possible, marine gravity data campaigns will be executed to fill in gaps in data coverage.
The second phase of the project will be mainly devoted to
comparisons between geoid estimation methods to evaluate the "best" geoid in the designated area.
Both collocation and integral methods will be used to combine the avaliable data (i.e. gravimetry and altimetry).
The geodetic results will be interpreted in terms of geophysical analysis and in terms of oceanographic investigations (e.g.
determination of the SST).
At the end of the project, new maps of gravity and geoid for the Mediterranean Sea will be avaliable for the scientific community together with an increased knowledge related to geoid
estimation in marine areas, gravity data inversion and
interpretation.
