Walter Munk

Historical

Oct 19, 1917

Walter Munk was a renowned oceanographer and geophysicist who contributed immensely to changing how oceanography and the geophysical processes of the Earth were viewed. Munk was born in Vienna, Austria, in 1917 and went to America at 14 with his family's intention of him going into banking. Nevertheless, Munk discovered his passion for science, especially physics and oceanography. He received his Bachelor of Science in physics at the California Institute of Technology (Caltech) in 1939 and later acquired a master's degree in geophysics. The significant change in Munk's career began when he joined Scripps Institution of Oceanography in 1939 to work for a PhD and conduct research that led to substantial and long-standing advancements in wave prediction, ocean acoustics, and climate change. In World War II, Munk collaborated with the United States Navy, where he devised ways of forecasting the wave conditions that would be essential in the process of D-Day and other amphibious assaults. After the war, he resumed his investigations of waves, tides, and the Earth's rotation, contributing to the development of oceanography and geophysics. Munk was involved in starting projects such as the Mohole Project, in which a hole was to be drilled through the Earth's crust to study the mantle. He developed ocean acoustic tomography, which used sound to detect ocean temperatures and currents over large distances. Munk worked for more than seven decades and was honored with many awards, such as the National Medal of Science, the Kyoto Prize, the National Academy of Science, and the Royal Society of London membership. His work continued to be valuable in studying global climate change, as evidenced by his research on sea level and ocean circulation. Munk died in 2019 at 101; he left behind a scientific legacy and several inventions.

Life and achievements

Early life

Walter Munk was born in 1917 in Vienna, Austria, to a Jewish family. His childhood and youth were influenced by the growth of European fascism, and in 1932, his family decided to emigrate to the United States, and he started attending a boys' preparatory school in New York. At first, Munk was supposed to continue his father's and grandfather's work in banking, but he did not like it and chose science instead. He attended Columbia University before joining the California Institute of Technology, better known as Caltech, where he graduated with a BSc in physics in 1939 and an MSc in geophysics in 1940. The change in Munk's career path to oceanography was initiated when he took a summer job at Scripps Institution of Oceanography in 1939, which he said made him fall in love with oceanography. He developed further interest in oceanography, especially under the tutelage of the director of Scripps, Harald Sverdrup. Munk's first interests were ocean waves and tides; he received his PhD in oceanography at the University of California at Los Angeles in 1947. Despite completing his thesis in only three weeks, this work is considered the precursor to his later discoveries in wave forecasting and ocean sound. Munk's exposure to military operations in the Second World War, especially forecasting wave conditions for amphibious operations, interested him in using oceanography.

Legacy

Walter Munk was one of the most outstanding oceanographers of the twentieth century and is still remembered as the \"Einstein of the Oceans.\" Munk's work during the Second World War prevented many deaths, while his post-war work helped scientists unravel the role of oceans in climate. Munk's most crucial contribution to oceanography is the invention of ocean acoustic tomography, which enabled scientists to measure the temperature and currents of the ocean over long distances using sound. This method proved instrumental in analyzing ocean currents and their effects on climate change. Another significant aspect of his work has been his activism for the environment and climate change, especially the impending problem of rising sea levels. Munk was highly appreciated for synthesizing physics, oceanography, and geophysics knowledge. He was awarded many honors and continued participating in scientific debates until his nineties. He passed on in 2019, which was the end of an era, but his work still encourages oceanographers and climate scientists to date.
