Sea-level variation in the Mediterranean sea as observed by altimeter and in-situ data

摘要

The Strait of Sicily separates the Mediterranean Sea into two different basins: West and East Basins, with important local and regional dynamic singularities, related to the geographic position and the sea-floor topography. Satellite Altimetry allows a wide global space-temporal coverage of the Mediterranean basins, including their interaction with water masses coming from the Atlantic Ocean and Black Sea, in the Strait of Gibraltar and Marmara Sea, respectively. We present in this communication an analysis of the accuracy of the different corrections applied to altimeter data and a study of the results obtained using the complete time series of Topex-Poseidon and ERS-2 altimeters data, in the two different basins described, comparing them with in-situ measurements.
