摘要：Sea temperature in oceanography is an important factor to figure out the quality of waters that the conducted mapping spatially and temporally. One of the potential technologies effectively can be carried out by mapping sea temperature is a coastal acoustic tomography system (CATs). This technology has never been implemented conducted in Balikpapan Bay before. The technology is able to reach out of a wide range of seawater area and to map sea temperature according to its depth layers.The purpose of this study is to reconstruct tomographic acoustic data to obtain ocean temperature values from travel time data that obtained between pair of stations, so it became a map of sea temperature distribution in CAT’s network. This research was taken by setting four reconstructed observational stations through inversion method of received acoustic travel time among paired stations. The average of temperatures in the formed tracks was analyzed by using Mackenzie formula.The results of reconstructing the seawater temperatures in the CATs tracking networks are in a range of 28o C – 30o C. Aalidation test of the seawater temperature data resulted from coastal acoustic tomography method by using a CTD (Conductivity Temperature Depth) generates the accuracies of the seawater temperature are more than 98% and a correlation coefficient R = 0.79. The finding of the study was the reconstruction of Acoustic Tomography data has succeeded in acquiring sea temperature data with a level of accuracy level of more than 97%.
