Regional Oral History Office University of California The Bancroft Library Berkeley, California University History Series Robert L. Wiegel COASTAL ENGINEERING: RESEARCH, CONSULTING, AND TEACHING, 1946-1997 With Introductions by Rodney J. Sobey and Orville Magoon An Interview Conducted by Eleanor Swent in 1997 Underwritten by The U.S. Army Corps of Engineers Copyright 1997 by the Regents' of the University of California Since 1954 the Regional Oral History Office has been interviewing leading participants in or well-placed witnesses to major events in the development of Northern California, the West, and the Nation. Oral history is a method of collecting historical information through tape-recorded interviews between a narrator with firsthand knowledge of historically significant events and a well- informed interviewer, with the goal of preserving substantive additions to the historical record. The tape recording is transcribed, lightly edited for continuity and clarity, and reviewed by the interviewee. The corrected manuscript is indexed, bound with photographs and illustrative materials, and placed in The Bancroft Library at the University of California, Berkeley, and in other research collections for scholarly use. Because it is primary material, oral history is not intended to present the final, verified, or complete narrative of events. It is a spoken account, offered by the interviewee in response to questioning, and as such it is reflective, partisan, deeply involved, and irreplaceable. ************************************ All uses of this manuscript are covered by a legal agreement between The Regents of the University of California and Robert L.

    May 20, 2016 Implement the Endangered Species Act Using the Best Available Science To: Secretary Sally Jewell and Secretary Penny Prtizker We, the under-signed scientists, recommend the U.S. government place species conservation policy on firmer scientific footing by following the procedure described below for using the best available science. A recent survey finds that substantial numbers of scientists at the U.S. Fish and Wildlife Service (FWS) and the National Oceanic and Atmospheric Administration believe that political influence at their agency is too high.i Further, recent species listing and delisting decisions appear misaligned with scientific understanding.ii,iii,iv,v,vi For example, in its nationwide delisting decision for gray wolves in 2013, the FWS internal review failed the best science test when reviewed by an independent peer-review panel.vii Just last year, a FWS decision not to list the wolverine ran counter to the opinions of agency and external scientists.viii We ask that the Departments of the Interior and Commerce make determinations under the Endangered Species Actix only after they make public the independent recommendations from the scientific community, based on the best available science. The best available science comes from independent scientists with relevant expertise who are able to evaluate and synthesize the available science, and adhere to standards of peer-review and full conflict-of-interest disclosure. We ask that agency scientific recommendations be developed with external review by independent scientific experts. There are several mechanisms by which this can happen; however, of greatest importance is that an independent, external, and transparent science-based process is applied consistently to both listing and delisting decisions.

    Walter Heinrich Munk

    WALTER HEINRICH MUNK 19 october 1917 . 8 february 2019 PROCEEDINGS OF THE AMERICAN PHILOSOPHICAL SOCIETY VOL. 163, NO. 3, SEPTEMBER 2019 biographical memoirs alter Heinrich Munk was a brilliant scholar and scientist who was considered one of the greatest oceanographers of W his time. He was born in Vienna, Austria in 1917 as the Austro-Hungarian Empire was declining and just before the death of one of its great artists, Gustav Klimt. Hedwig Eva Maria Kiesler, who later changed her name to Hedy Lamarr to accommodate her film career, was one of Walter’s childhood friends.1 Walter’s mother, Rega Brunner,2 the daughter of a wealthy Jewish banker, divorced Walter’s father in 1927 and married Dr. Rudolf Engelsberg in 1928. By age 14, Walter apparently had not distinguished himself in his school studies and announced that he intended to become a ski instructor. Walter later claimed that it was this that caused his mother to send him to work at a family bank in New York. The validity of this claim should be tempered by the political turmoil in Germany and its proximity to Austria. In any case, Walter left Vienna in 1932. In New York, he attended Silver Bay Preparatory School for Boys on Lake George and then became a lowly employee in the Cassel Bank, which was associated with the family’s Brunner Bank in New York. In the meantime, Walter restarted his education at Columbia’s Extension School. He greatly disliked the work at the bank and apparently made a number of mistakes, which didn’t endear him to the owners of the Cassel Bank.

But our paths had crossed much earlier, anonymously to be sure, when Walter survived the first thermonuclear explosion, on a small raft in the vast Pacific Ocean. This was the 10-megaton MIKE test on Enewetak Atoll, in the Marshall Islands. In a few minutes we’ll hear Walter’s account of the experience1. I came to know Walter well when I joined JASON in 1966, and I was able to benefit from his insights and experience. Since about 1957 I had worked almost half time with the President’s Science Advisor Committee (PSAC), created late that year by President Dwight D. Eisenhower. Although not yet a PSAC member, I had been asked to chair its Military Aircraft Panel and its AntiSubmarine Warfare Panel. It was in that latter context that I appreciated Walter as a scientist—energetic, imaginative, bold, courageous, and thorough. We’ll see Walter later in this talk, commenting on JASON, but first I list the JASON reports which he authored, usually with others who drew on and extended Walter’s long experience and deep understanding of the oceans and the science and phenomenology involved.
  • Hydrodynamic Forces on a Horizontal Cylinder Under Waves and Current Are Examined

    Hydrodynamic Forces on a Horizontal Cylinder Under Waves and Current Are Examined

    AN ABSTRACT OF THE THESIS OF Chung-Chu Teng for the degree ofMaster of Ocean Engineering in Civil Engineering presented on March 10, 1983 Title: HYDRODYNAMIC FORCES ON A HORIZONTAL CYLINDER UNDER WAVES AND CURRENT Redacted for Privacy ABSTRACT APPROVED: Dr. John H. Nath By assuming the linear superposition principle to be valid, the hydrodynamic forces on a horizontal cylinder under waves and current are examined. In this study, towing a cylinder in waves is used to simulate a cylinder underwaves and current. The experimental technique is proved valid throughtheoretical considerations and experimental investigations. For large current velocity (or high tow speed), the drag coefficient for waves and current approaches that for steady flow. If the current is large enough, these two values are nearly identical. In addition, the behavior of force coefficientsfor a horizontal cylinder in waves only with moderately large Reynolds number, Keulegan-Carpenter number and frequency parameter is examined. The results show that the forces ona horizontal cylinder in waves are smaller than those for planar oscillatory flow. Whether the totalacceleration or localacceleration should be used in the inertia term is a debatable point for using the Morison equation. To study this problem, the similarities and differences between these two accelerations for different water depths and wave heights are examined. The results show there is no evident difference in force prediction if the related force coefficients are used. To check the suitability of this data

There is now general agreement of a M2 dissipation by 2.5 Terawatts ( 1 TW = 10 ~2 W), based on four quite separate astronomic observational programs. Allowing for the bodily tide dissipation of 0.1 TW leaves 2.4 TW for ocean dissipation. The traditional disposal sites since JEFFREYS (1920) have been in the turbulent bottom boundary layer (BBL) of marginal seas, and the modern estimate of about 2.1 TW is in this tradition (but the distribution among the shallow seas has changed radically from time to time). Independent estimates of energy flux into the mar- ginal seas are not in good agreement with the BBL estimates. T/P altimetry has contributed to the tidal problem in two important ways. The assimilation of global altimetry into Laplace tidal solutions has led to accurate representations of the global tides, as evidenced by the very close agreement between the astronomic measurements and the computed 2.4 TW working of the Moon on the global ocean. Second, the detection by RAY and MITCHUM (1996) of small surface manifestation of internal tides radiating away from the Hawaiian chain has led to global estimates of 0.2 to 0.4 TW of conversion of surface tides to internal tides.

  • The Luck of Walter Munk

    The Luck of Walter Munk

    015K1999_KP_LE_B_en.doc The Luck of Walter Munk Walter H. Munk We have been asked to talk about ourselves. For a title, I have chosen the title of a talk given by Roger Revelle in 1982＊. I was born in Austria soon after the end of World War I. My grandfather Lucian Brunner [photo 1] was a Viennese banker with political ambitions. He ran for mayor on a reform platform and was thoroughly defeated. He became a socialist and changed the name of his bank from “Lucian Brunner” to “Österreichische Volksbank” (Austrian People’s Bank), but kept all the shares. Grandfather was intrigued by high technology. He was on the board of the “Südbahn,” the railroad that developed the audacious route from Vienna to Trieste, and he built funiculars in the Dolomites. This area is now in Italy, but was then part of Austria. At the time it would have made some sense for an Austrian to become an oceanographer. Austria had inherited the northern Adriatic, down to Venice, from Napoleon, had a Navy and was doing respectable ocean research. But by the time I grew up the country was landlocked, and becoming an oceanographer made no sense at all. Lucian’s daughter, my mother [photo 2], read botany at Newnham, one of the two women’s colleges at Cambridge University. It was then unheard of for a girl from the continent to go to university in England. She married my father at the end of the war. They were divorced when I was very young, and father went to live and ski in Kitzbuehel.
