Walter Munk
Walter Heinrich Munk (October 19, 1917 – February 8, 2019) was an American physical oceanographer. He was one of the first scientists to bring statistical methods to the analysis of oceanographic data. Munk worked on a wide range of topics, including surface waves, geophysical implications of variations in the Earth's rotation, tides, internal waves, deep-ocean drilling into the sea floor, acoustical measurements of ocean properties, sea level rise, and climate change. His work won awards including the National Medal of Science, the Kyoto Prize, and induction to the French Legion of Honour.
Munk's career began before the outbreak of World War II and ended nearly 80 years later with his death in 2019. The war interrupted his doctoral studies at the Scripps Institution of Oceanography (Scripps), and led to his participation in U.S. military research efforts. Munk and his doctoral advisor Harald Sverdrup developed methods for forecasting wave conditions which were used in support of beach landings in all theaters of the war. He was involved with oceanographic programs during the atomic bomb tests in Bikini Atoll.
Beginning in 1975, Munk and Carl Wunsch developed ocean acoustic tomography to exploit the ease with which sound travels in the ocean and use acoustical signals for measurement of broad-scale temperature and current. In a 1991 experiment, Munk and his collaborators investigated the ability of underwater sound to propagate from the Southern Indian Ocean across all ocean basins, with the aim of measuring global ocean temperature. The experiment was criticized by environmental groups, who expected that the loud acoustic signals would adversely affect marine life. Munk continued to develop and advocate for acoustical measurements of the ocean throughout his career.
For most of his career, he was a professor of geophysics at Scripps at the University of California in La Jolla. Additionally, Munk and his wife Judy were active in developing the Scripps campus and integrating it with the new University of California, San Diego. Munk's career included being a member of the JASON think tank, and holding the Secretary of the Navy/Chief of Naval Operations Oceanography Chair.
In 1917, Munk was born to a Jewish family in Vienna, Austria-Hungary. His father, Dr. Hans Munk, and his mother, Rega Brunner, divorced when he was ten years old. His maternal grandfather was Lucian Brunner (1850–1914), a prominent banker and Austrian politician. His stepfather, Dr. Rudolf Engelsberg, was head of the salt mine monopoly of the Austrian government and a member of the Austrian governments of Chancellor Engelbert Dollfuss and Chancellor Kurt Schuschnigg.
In 1932, Munk was performing poorly in school because he was spending too much time skiing, so his family sent him from Austria to a boys' preparatory school in upper New York state. His family envisioned a career for him in finance with a New York bank connected to the family business. He worked at the family's banking firm for three years and studied at Columbia University.
Munk hated banking. In 1937, he left the firm to attend the California Institute of Technology (Caltech) in Pasadena. While at Caltech, he took a summer job in 1939 at the Scripps Institution of Oceanography (Scripps) in La Jolla, California. Munk earned a B.S. in applied physics in 1939 and an M.S. in geophysics (under Beno Gutenberg) in 1940 at Caltech. The master's degree work was based on oceanographic data collected in the Gulf of California by the Norwegian oceanographer Harald Sverdrup, then director of Scripps.
In 1939, Munk asked Sverdrup to take him on as a doctoral student. Sverdrup agreed, although Munk recalled him saying "I can't think of a single job that's going to become available in the next ten years in oceanography". Munk's studies were interrupted by the outbreak of World War II. He completed his doctoral degree in oceanography at Scripps under the University of California, Los Angeles in 1947. He wrote it in three weeks and it is the "shortest Scripps dissertation on record." He later realized that its principal conclusion is wrong.
