One of the many people to take an interest in HIFT was Jacques Cousteau. In a visit to CSIRO Division of Oceanography in Hobart, Tasmania, Andrew Forbes had the opportunity to explain the principle of acoustic thermometry to him. Cousteau listened intently and asked some excellent questions, evidence of a keen interest in ocean science. Notable was his response to one of the accompanying reporters who asked, "Monsieur Cousteau, if this experiment manages to measure ocean climate change, what can we do to mitigate of reverse it?" Cousteau answered simply, "We are too many - we must control ze growth of ze population".
