Renowned Oceanographer Walter Munk Receives Crafoord Prize
Royal Swedish Academy of Sciences recognized Munk's lifetime of research achievement with geosciences prize
Scripps Institution of Oceanography / University of California, San DiegoScripps Institution of Oceanography at UC San Diego scientist Walter Munk, often referred to as the world's "greatest living oceanographer," was honored May 11 by Majesty the King of Sweden with the 2010 Crafoord Prize during an award ceremony at the Royal Swedish Academy of Sciences in Stockholm, Sweden.
On May 12, Munk gave the 2010 Crafoord Prize Lecture, titled "The Sound of Climate Change" at the Geobiosphere Science Centre at Lund University. His lecture considered how climate change predictions depend on appropriate atmosphere and ocean observations and how underwater transmissions of sound over very long distances -- some half way around the globe -- can provide evidence of global ocean warming.
The academy recognized Munk "for his pioneering and fundamental contributions to our understanding of ocean circulation, tides and waves, and their role in the Earth's dynamics."
In its citation, the academy noted Munk's contributions to several areas of oceanography, but especially to the understanding of circulation and tides:

"The great adventure of exploring the world's oceans took place largely in the latter half of the 20th century, when new technology and novel methods of remote analysis had become invaluable tools for oceanographers. This year's Crafoord Prize Laureate, Walter Munk, is a person who, in his work of explaining ocean circulation, tides and waves, and their role in our planet's dynamics, moved in the absolute forefront of science throughout this period. In particular, Munk's grasp of the tide's significance on various scales is crucial to his scientific oeuvre."
The prize committee also recognized Munk's contributions to other fields such as biology and astronomy that were not even fully appreciated until several decades after he performed his original work.
"In 1960, thanks to his geophysical approach, Munk was able to describe irregularities in the Earth's rotation in a way that was, at the time, entirely new," the academy said. "He discussed polar movement and variations in the Earth's rotation speed on various timescales and was able to show that, over a century or more, the friction of the tide is what most affects the Earth's rotation, by causing its gradual deceleration. Nowadays, the consequent gradual lengthening of the Earth's day is taken into account in the calculation of Coordinated Universal Time (UTC), with the addition of an extra 'leap second' in certain years."
Winners of the Crafoord Prize receive $500,000. The prize fund was established in 1980 by a donation to the Royal Swedish Academy of Sciences from Anna-Greta and Holger Crafoord. The Crafoord Prize was awarded for the first time in 1982 and recognizes achievement in astronomy and mathematics and biosciences in addition to geosciences. Each discipline is recognized annually in rotating fashion. The prize also periodically recognizes achievement in the field of polyarthritis.
Munk received a Ph.D. in oceanography in 1947 from Scripps Institution of Oceanography and has spent his entire professional career at Scripps. In 1947 he became an assistant professor. In 1954 he became a professor of geophysics and also was named a member of the University of California's Institute of Geophysics, and, in 1960, he established a branch of the institute on the Scripps campus in La Jolla, Calif. Until 1982, he served as director of the Scripps branch and as an associate director of the university-wide institute, which was renamed the Institute of Geophysics and Planetary Physics (IGPP). Munk's association with IGPP continues to this day.
Munk has won numerous awards during his research career. He received the National Medal of Science in 1983 and the 1999 Kyoto Prize in Basic Sciences for his fundamental contributions to the field of oceanography, the first time the prize was awarded to an oceanographer. In 2001, he was the inaugural recipient of the Prince Albert I Medal in the physical sciences of the oceans, which Prince Rainier of Monaco created in cooperation with the International Association for the Physical Sciences of the Oceans.
Munk is the first researcher from Scripps Oceanography to win the Crafoord Prize.

Scripps Institution of Oceanography, at University of California, San Diego, is one of the oldest, largest and most important centers for global science research and education in the world. The National Research Council has ranked Scripps first in faculty quality among oceanography programs nationwide Now in its second century of discovery, the scientific scope of the institution has grown to include biological, physical, chemical, geological, geophysical and atmospheric studies of the earth as a system. Hundreds of research programs covering a wide range of scientific areas are under way today in 65 countries. The institution has a staff of about 1,300, and annual expenditures of approximately $155 million from federal, state and private sources. Scripps operates one of the largest U.S. academic fleets with four oceanographic research ships and one research platform for worldwide exploration.
