N2 - This paper presents a new ray travel-time inversion scheme not only for localizing the source and calibrating the array position, but also for characterizing environmental parameters such as sound speed profiles (in both water column and sediment), bathymetry, etc. Special attention is given to link the unknowns to good physical observables in order to enhance robustness and efficiency. Numerical studies show the algorithm is indeed extremely efficient. The algorithm is also shown to be insensitive to model mismatch and to yield quite accurate results. This paper also focuses on specific Lincoln-Sea application and analysis of a specific data set from Iceshelf-89.
