The principal objective of ACOUS is to conduct a research program to monitor changes in the ocean temperature and extent of ice cover in the Arctic Ocean using underwater acoustic remote sensing. The first objective of this research is to measure directly Arctic Ocean temperature trends and the upper mixed layer depth using acoustic thermometry and innovative acoustic technologies. The second objective of this research is to measure directly changes in the Arctic Ocean ice cover thickness and extent using an acoustic intensity based tomographic method. The third objective of this research is to assimilate these data into Arctic Ocean-Ice-Atmosphere models, and to merge them with satellite temperature, altimeter, and SAR data acquired in other programs. The fourth objective is to continue the close association with the Russian former defense S&T community and assist in the survival of Russian technology infrastructure and its conversion to non-defense applications. ACOUS is an approved Gore-Chernomyrdin project since 1995. See also ADM002252.
