Abstract
Moving Ship Tomography (MST) is a method of obtaining high‐resolution, nearly synoptic three‐dimensional maps of the ocean temperature field over large areas [Cornuelle et al., 1989]. We measure acoustic travel times along a multitude of paths crossing at many different angles and then reconstruct the sound speed (temperature) field in a manner analogous to a medical CAT‐scan. A large number of crossing ray paths are generated by using a moving receiver. This report compares preliminary maps of sound speed obtained using acoustic data (Figure 1) with maps obtained with air expendable bathythermograph (AXBT) and conductivity, temperature, depth (CTD) profile data. Given such maps, we will be able to study advecting fronts and interacting eddies with high resolution and test how well numerical models can predict the evolving fields.
