Over the past 25 years, there has been significant research activity in development and application of methods for inverting acoustical field data to estimate parameters of geoacoustic models of the ocean bottom. Although the performance of various geoacoustic inversionmethods has been benchmarked on simulated data, their performance with experimental data remains an open question. This article constitutes the first attempt of an experimental benchmark of geoacoustic inversionmethods. To do so, the article focuses on data from experiments carried out at a common site during the ShallowWater 2006 (SW06) experiment. The contribution of the article is twofold. First, the article provides an overview of experimental inversionmethods and results obtained with SW06 data. Second, the article proposes and uses quantitative metrics to assess the experimental performance of inversion methods. From a sonar performance point of view, the benchmark shows that no particular geoacousti.....
