Description
Summary:The objective is to develop and design an acoustic system for long-term monitoring of the ocean temperature and ice thickness in the Arctic Ocean, including the Fram Strait, for climate variability studies and global warming detection. The approach is to detect and quantify global warming in the Arctic Ocean, using gyre scale acoustic long range propagation for basin wide ocean temperature and ice thickness changes. Acoustic propagation, which has been successfully tested for climate monitoring in other oceans, will be an important component in addition to remote sensing of sea ice from satellites, in situ observations and modelling. An acoustic monitoring system can potentially be used to verify such warming in the Arctic Ocean. The unique combination of the underwater acoustic remote sensing with satellite remote sensing of the ice cover including modelling and data assimilation, in the predicted sensitive climate region of the Arctic Ocean, is perhaps the key solution to monitor global climate changes and ... : NERSC Technical Report no. 162.
