Abstract: The properties of coastal ocean environments often show a high variability with time and space (range, cross-range, depth). While direct measurements of these properties can be time consuming and o er usually a poor coverage, acoustic inversion represents an attractive alternative to estimate these properties [1, 2]. The ATOMS project aims to study a coastal environment featuring a cold water  lament among warmer waters. One of the major goals of the project is to show that it is possible to detect and characterize such a  lament in space and time using an acoustic inversion method. The current work is a preliminary study in the project as it deals with a simpli ed approach to the global problem: 1- The particular case of a 2-D environment (vertical slice) is investigated. This means that we consider only the variations of the properties in the vertical plane de ned by the acoustic source and a vertical line array. 2- Time variability is not considered. 3- Although they are based on experimental records of a  lament [3], the data used here are only simulated data.
