N2 - Mapping of water temperature and current dynamic progress in ocean, coastal region and island is a the research emphasis. A coastal acoustic tomography (CAT) experiment for reconstructing the average temperature and current in Huangcai reservoir, Changsha, China was successfully carried out by three acoustic tomography stations during February 28th to March 2nd, 2022. The grid slice method is used to reconstruct grid-averaged temperature and grid-averaged current in 2D vertical profile. The new shore system and multi shallow systems synchronized atomic clock are used. And the function of new shallow-type system and experimental site are verified. From the inversion results of experiment, temperature flied has a significant stratification characteristic and current filed is influenced by terrain of the observation area. And the upwelling and downwelling current exist at the edge of exchange layer. The relationship between band frequency and station distance are also discussed.
