Monitoring the heat content and mass transport of oceans over long distances is becoming increasingly important for understanding the impacts of oceans to the formation and evolution of typhoons, severe weather events, and climate change. Ocean acoustic tomography (OAT) is a promising technique as it has the potential to provide systematic, instantaneous and repeated measurements of the ocean interior over large scale.

The purpose of this workshop is to attract young scientists to the field of OAT. The lectures will cover theory, simulation, hardware, field experiments, and its applications to marine environment and climate monitoring. All lecture notes will be divided into four parts: to the undergrads, to first year Master students, to Ph.D. students, and to advanced researchers on current research.
