Novel Method for the Estimation of Vertical Temperature Profiles Using a Coastal Acoustic Tomography System

Frontiers in Marine Science, 2021
Systems based on remote sensing technology, which use reciprocal acoustic signals to continuously monitor changes in the coastal oceanic environment, are referred to as coastal acoustic tomography (CAT) systems. These systems have been applied in regions
