Fred Fisher's high pressure work with eyewash and epsom salts
Abstract
Starting in 1957 Fred Fisher led research programs devoted to high‐pressure measurementsrelated to the physical chemistry of sound absorption in seawater due to magnesium sulfate and other salts. As he put it, he spent his professional lifetime squeezing epsom salt. His interest in the low‐frequency anomalous sound absorption in the ocean below 1 kHz led to the discovery of boric acid as the cause of the low‐frequency relaxation. This paper is a short review of Fred Fisher’s contributions to our knowledge of sound absorption in seawater, based in part on his carefully hand‐written lecture notes and numerous low‐pressure discussions.
