Cet article r\u00e9sume les r\u00e9sultats de l’\u00e9tude de la variabilit\u00e9 spatio-temporelle du niveau moyen de la mer M\u00e9diterran\u00e9e ainsi que sa repr\u00e9sentation par les modes fondamentaux permettant une r\u00e9duction des donn\u00e9es. L\u2019analyse de la s\u00e9rie temporelle d\u2019anomalies moyennes de hauteur de la mer (ou sea level anomalies-SLA), issues des mesures recueillies par les diff\u00e9rentes missions d\u2019altim\u00e9trie satellitaire sur la p\u00e9riode de janvier 1993 \u00e0 d\u00e9cembre 2015, montre une diff\u00e9renciation \u00e9vidente Est-Ouest. Le bassin oriental a augment\u00e9 de fa\u00e7on tr\u00e8s nette. Par contre, au niveau de l’Italie (mer Ionienne), le niveau a baiss\u00e9. Afin de d\u00e9crire les modes fondamentaux de variabilit\u00e9, une d\u00e9composition du set des donn\u00e9es en fonctions orthogonales empiriques (EOF) a \u00e9t\u00e9 effectu\u00e9e. Les fonctions calcul\u00e9es, tronqu\u00e9es \u00e0 20, permettent une r\u00e9duction de l’espace des donn\u00e9es tout en expliquant pr\u00e9s de 80% de la variance des donn\u00e9es analys\u00e9es. Les cartes reconstruites \u00e0 partir des EOFs estim\u00e9s sont en concordance avec les donn\u00e9es sources.<\/p>\n
