Early life and educationEdit
Munk was born in 1917 in Vienna, Austria-Hungary, to a Jewish family. His father, Dr. Hans Munk, and his mother, Rega Brunner, divorced when Munk was ten years old. His maternal grandfather was a prominent banker and Austrian politician, Lucian Brunner (1850–1914). His stepfather, Dr. Rudolf Engelsberg, was head of the Austrian salt mine monopoly, hence a member of the Austrian governments of Chancellors Engelbert Dollfuss (assassinated by Nazis in 1934) and Kurt Schuschnigg (resigned after the Anschluss in 1938).
Munk was spending too much time skiing and was performing poorly in school, so he was sent to a boys' preparatory school in upper New York state in 1932. The family selected New York because they envisioned a career in finance for Munk in a New York bank with connections to the family business. Munk worked at the banking firm for three years and studied at Columbia University.
Munk hated banking, however, and in 1937 he left the firm to attend the California Institute of Technology (Caltech) in Pasadena. While at Caltech, Munk 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 in 1940 at Caltech. Though the M.S. degree was at Caltech, the work was based on oceanographic data collected in the Gulf of California by the Norwegian oceanographer Harald Ulrik Sverdrup. Sverdrup, the director of Scripps, was the thesis advisor.
In 1939, Munk asked Sverdrup to take him on as a doctoral student. Sverdrup agreed, but told Munk that he did "not know of a single job in oceanography which would become available in the next decade". Munk's studies were interrupted by the outbreak of World War II, however. He completed his doctoral degree in oceanography at Scripps under the University of California, Los Angeles in 1947.
Munk married Martha Chapin in the late 1940s. The marriage ended in divorce in 1953.
On June 20, 1953, Munk married Judith Horton. She was an active participant at Scripps for decades, where she made contributions to architecture, campus planning, and the renovation and reuse of historical buildings. The Munk's were frequent traveling companions. Judith Munk died in 2006.
Munk married La Jolla community leader Mary Coakley in June 2011.
Munk obtained American citizenship in 1939, and, after the Anschluss, he enlisted in the ski troops of the U.S. Army as a private. Enlistment in the Army was unusual, as all the other young men at Scripps joined the U.S. Naval Reserve. At the request of Sverdrup and Roger Revelle, Munk was discharged from military service to undertake defense-related research at Scripps. His discharge was in December 1941, a week before the Japanese Attack on Pearl Harbor. He joined several of his colleagues from Scripps at the U.S. Navy Radio and Sound Laboratory, where they developed methods related to antisubmarine and amphibious warfare.
Predicting surf conditions for Allied landingsEdit
In 1943, Munk and Sverdrup began working on the problem of predicting heights of ocean surface waves. Munk had observed troops in practice beach landings in the Carolinas and noted that waves larger than about five feet were dangerous to people and landing craft. The methods they developed to predict surf conditions were used during Allied landings in North Africa, the Pacific theater of war, and on D-Day during the Normandy invasion. Countless lives were saved by these predictions. Munk commented in 2009:
The Normandy landing is famous because weather conditions were very poor and you may not realize it was postponed by General Eisenhower for 24 hours because of the prevailing wave conditions. And then he did decide, in spite of the fact that conditions were not favorable, it would be better to go in than lose the surprise element, which would have been lost if they waited for the next tidal cycle [in] two weeks.
Oceanographic measurements during atomic weapons tests in the PacificEdit
In 1946, the United States tested two fission nuclear weapons (20 kilotons) at Bikini Atoll in the equatorial Pacific in Operation Crossroads. Munk helped to analyze the currents, diffusion, and water exchanges affecting the radiation contamination from the second test, code-named Baker. Munk returned to the equatorial Pacific six years later to Eniwetok Atoll, for the 1952 Ivy Mike test of a fusion nuclear weapon (10 megatons). Roger Revelle, John Isaacs, and Munk had initiated a program for monitoring for the possibility of a large tsunami generated from the test.
The Institute of Geophysics and Planetary Physics in La Jolla, IGPP/LJEdit
After receiving his doctorate in 1947, Munk was hired by Scripps as an assistant professor of geophysics. He became a full professor there in 1954.
In 1955, Munk took a sabbatical at Cambridge University in England with a Guggenheim Fellowship. Returning to Scripps in 1956, Munk developed plans for a La Jolla branch of the Institute of Geophysics, then a part of the University of California, Los Angeles. With the new branch of IGP, an institution of the wider University of California system, to be focused on planetary physics with an emphasis on the Earth-Moon system, IGP changed its name to the Institute of Geophysics and Planetary Physics, IGPP. IGPP at La Jolla was built between 1959–1963 with funding from the University of California, the U.S. Air Force Office of Scientific Research, the National Science Foundation, and private foundations. The redwood building was designed by architect Lloyd Ruocco, in close consultation with Judith and Walter Munk. The IGPP buildings have become the center of the Scripps campus. Among the early faculty appointments were Carl Eckart, George Backus, Freeman Gilbert and John Miles. The eminent geophysicist Sir Edward "Teddy" Bullard was a regular visitor to IGPP. In 1971 an endowment of $600,000 was established by Cecil Green to support visiting scholars, now known as Green Scholars. Munk served as director of IGPP/LJ from 1962–1982.
As an academic institution, from 1938 until 1958 Scripps was under the administration of the University of California, Los Angeles. Scripps became part of the University of California, San Diego when it was formed in 1958. Roger Revelle, then director of Scripps, was a primary advocate for establishing the La Jolla campus.
In the late 1980s, plans for an expansion of IGPP were developed by Judith and Walter Munk, and Sharyn and John Orcutt, in consultation with a local architect, Fred Liebhardt. The Revelle Laboratory was completed in 1993. At this time the original IGPP building was renamed the Walter and Judith Munk Laboratory for Geophysics. In 1994 the Scripps branch of IGPP was renamed the Cecil H. and Ida M. Green Institute of Geophysics and Planetary Physics.
Munk's career in oceanography and geophysics touched on disparate and innovative topics. A pattern of Munk's work was that he would initiate a completely new topic, ask challenging, fundamental questions about the subject and its larger meaning, then, having created an entirely new sub-field of science, move on to another new topic. As Carl Wunsch, one of Munk's frequent collaborators, commented:
[Walter has] a sometimes uncanny ability to delineate the essence - that had eluded his predecessors - of a central problem. He has the knack of defining a field in a way that requires decades of subsequent work by others to fully flesh-out, while he himself moves on. One of his explicitly stated themes is that it is more important to ask the right questions than it is to give the right answers.
In 1948, Munk took a year's sabbatical to visit Sverdrup in Oslo, Norway on his first Guggenheim Fellowship. He worked on the problem of wind-driven ocean circulation. Munk's pioneering research, published in 1950, showed that Gulf Stream transport could be approximately computed by integrating the wind stress across the Atlantic. Munk coined the term "wind-driven gyres," a term now widely used.
Rotation of the EarthEdit
In the 1950s, Munk investigated irregularities in the Earth's rotation, such as the Chandler wobble and annual and long-term changes in the length of day (rate of the Earth's rotation), to see how these were related to geophysical processes such as the changes in the atmosphere, ocean, and core, and the energy dissipated by tidal acceleration. He also investigated how western boundary currents, such as the Gulf Stream, dissipated planetary vorticity. Munk thoroughly reviewed and explored the subject in the 1960 monograph, written with G.J.F. MacDonald, The Rotation of the Earth: A Geophysical Discussion. The discussion was written from a geophysical, rather than astronomical, perspective. The monograph became a standard reference.
In 1957, Munk and Harry Hess suggested the idea behind Project Mohole: to drill into the Mohorovicic Discontinuity and obtain a sample of the Earth's mantle. While such a project was not feasible on land, drilling in the open ocean would be more feasible, because the mantle is much closer to the sea floor. Initially led by the informal group of scientists known as the American Miscellaneous Society (AMSOC, including Hess, Maurice Ewing, and Roger Revelle), the project was eventually taken over by the National Science Foundation (NSF). Initial test drillings into the sea floor led by Willard Bascom occurred off Guadalupe Island, Mexico in March and April 1961. The project became mismanaged and increasingly expensive after Brown and Root won the contract to continue the effort, however, and Congress discontinued the project toward the end of 1966. While Project Mohole was not successful, the idea led to projects such as NSF's Deep Sea Drilling Program.
Starting in the late 1950s, Munk returned to the study of ocean waves, and, thanks to his acquaintance with John Tukey, he pioneered the use of power spectra in describing wave behavior. This work culminated with an experiment that he led in 1963 to observe waves generated by winter storms in the Southern Hemisphere and traveling thousands of miles throughout the Pacific Ocean. To trace the path and decay of waves as they propagated northward, he established stations to measure waves from islands and at sea (on R/P FLIP) along a great circle from New Zealand, to the Palmyra Atoll, and finally to Alaska. Munk and his family spent nearly the whole of 1963 on American Samoa for this experiment. Walter and Judith Munk collaborated in making the film "Waves Across the Pacific" to document the experiment. The results showed little decay of wave energy with distance traveled. This work, together with the wartime work on wave forecasting, led to the science of surf forecasting, one of Munk's best-known accomplishments. Munk's pioneering research into surf forecasting was acknowledged in 2007 with an award from the Groundswell Society, a surfing advocacy organization.
Between 1965 and 1975, Munk turned to investigations of ocean tides, partially motivated by their effects on the Earth's rotation. Modern methods of time-series and spectral analysis were brought to bear on tidal analysis, leading to the development of the "response method" of tidal analysis. With Frank Snodgrass, Munk developed deep-ocean pressure sensors that could be used to provide tidal data far from any land. One highlight of this work was the discovery of the semidiurnal amphidrome midway between California and Hawaii.
Internal waves: The Garrett-Munk SpectrumEdit
At the time of Munk's dissertation for his master's degree in 1939, internal waves were considered to be an uncommon phenomenon. By the 1970s, there were extensive published observations of internal-wave variability in the oceans in temperature, salinity, and velocity as functions of time, horizontal distance, and depth. Motivated by a 1958 paper by Owen Philips that described a universal spectral form for the variance of ocean surface waves as a function of wave number, Chris Garrett and Munk attempted to make sense of the observations by postulating a universal spectrum for internal waves. According to Munk, they chose a spectrum that could be factored into a function of frequency times a function of vertical wave number. The resulting spectrum, now called the Garrett-Munk Spectrum, was roughly consistent with a large number of diverse measurements that had been obtained over the global ocean. The model evolved over the subsequent decade, denoted GM72, GM75, GM79, etc., according to the year of publication of the revised model. Although Munk expected the model to be rapidly obsolete, it proved to be a universal model that is still in use. Its universality has been interpreted as indicating profound processes governing internal wave dynamics, turbulence and fine-scale mixing. Klaus Hasselmann commented in 2010, "...the publication of the GM spectrum has indeed been extremely fruitful for oceanography, both in the past and still today."
Ocean acoustic tomographyEdit
Beginning in 1975, Munk and Carl Wunsch of the Massachusetts Institute of Technology pioneered the development of acoustic tomography of the ocean. With Peter Worcester and Robert Spindel, Munk developed the use of sound propagation, particularly sound arrival patterns and travel times, to infer important information about the ocean's large-scale temperature and current. This work, together with the work of other groups, eventually motivated the 1991 "Heard Island Feasibility Test", to determine if man-made acoustic signals could be transmitted over antipodal distances to measure the ocean's climate. The experiment came to be called "the sound heard around the world." During six days in January 1991, acoustic signals were transmitted by sound sources lowered from the M/V Cory Chouest near Heard Island in the southern Indian Ocean. These signals traveled half-way around the globe to be received on the east and west coasts of the United States, as well as at many other stations around the world. The follow-up to this experiment was the 1996–2006 Acoustic Thermometry of Ocean Climate (ATOC) project in the North Pacific Ocean, which engendered considerable public controversy concerning the effects of man-made sounds on marine mammals.
Tomography has come to be a valuable method of ocean observation, exploiting the characteristics of long-range acoustic propagation to obtain synoptic measurements of average ocean temperature or current. Applications have included the measurement of deep-water formation in the Greenland Sea in 1989, measurement of ocean tides, and the estimation of ocean mesoscale dynamics by combining tomography, satellite altimetry, and in situ data with ocean dynamical models. In addition to the decade-long measurements obtained in the North Pacific, acoustic thermometry has been employed to measure temperature changes of the upper layers of the Arctic Ocean basins, which continues to be an area of active interest. Acoustic thermometry has also been used to determine changes to global-scale ocean temperatures using data from acoustic pulses sent from one end of the Earth to the other.
Tides and mixingEdit
In the 1990s, Munk returned to the work on the role of tides in producing mixing in the ocean. In a 1966 paper "Abyssal Recipes", Munk was one of the first to assess quantitatively the rate of mixing in the abyssal ocean in maintaining oceanic stratification. According to Sandström's theorem (1908), without the occurrence such mixing, driven by, e.g., internal tides or tidally-driven turbulence in shallow regions, most of the ocean would become cold and stagnant, capped by a thin, warm surface layer. The question of tidal energy available for mixing was reawakened in the 1990s with the discovery, by acoustic tomography and satellite altimetry, of large-scale internal tides radiating energy away from the Hawaiian Ridge into the interior of the North Pacific Ocean. In the 1960s, tidal energy available for mixing was thought to occur by processes near ocean boundaries. The tidal energy available for mixing from the scattering of large-scale internal waves from mid-ocean ridges was much larger.
In his later work, Munk focused on the relation between changes in ocean temperature, sea level, and the transfer of mass between continental ice and the ocean. This work described what came to be known as "Munk's enigma", a large discrepancy between observed rate of sea level rise and its expected effects on the earth's rotation.
Munk was elected to the National Academy of Sciences in 1956 and to the Royal Society of London in 1976. He was both a Guggenheim Fellow (1948, 1953, 1962) and a Fulbright Fellow. He was also named California Scientist of the Year by the California Museum of Science and Industry in 1969. Among the many other awards and honors Munk received are the Arthur L. Day Medal, from the Geological Society of America in 1965, the Sverdrup Gold Medal of the American Meteorological Society in 1966, the Gold Medal of the Royal Astronomical Society in 1968, the first Maurice Ewing Medal sponsored by the American Geophysical Union and the U.S. Navy in 1976, the Alexander Agassiz Medal of the National Academy of Sciences in 1976, the Captain Robert Dexter Conrad Award from the U.S. Navy in 1978, the National Medal of Science in 1983, the William Bowie Medal of the American Geophysical Union in 1989, the Vetlesen Prize in 1993, the Kyoto Prize in 1999, the first Prince Albert I Medal in 2001, and the Crafoord Prize of the Royal Swedish Academy of Sciences in 2010 "for his pioneering and fundamental contributions to our understanding of ocean circulation, tides and waves, and their role in the Earth's dynamics". In July 2018 at the age of 100, Munk was appointed a Chevalier of France's Legion of Honour in recognition of his contributions to oceanography.
In 1993, Munk was the first recipient of the Walter Munk Award given "in Recognition of Distinguished Research in Oceanography Related to Sound and the Sea." This award is given jointly by the Oceanography Society, the Office of Naval Research and the US Department of Defense Naval Oceanographic Office.
