Laureados[editar | editar código-fonte]

Esta é a lista de premiados com esta medalha:[2]

Ano[A] Laureado Motivo
1913 Johan Hjort
1918 Alberto I, Príncipe do Mónaco "for his original contributions to the science of oceanography"
1920 Admiral Charles Dwight Sigsbee
1924 Otto S. Pettersson "for his studies on the chemistry and physics of the sea"
1926 Vilhelm Bjerknes "for his outstanding contributions to dynamic oceanography"
1927 Max Carl Wilhelm Weber "for his distinguished research in the field of oceanography"
1928 Vagn Walfrid Ekman "for his work in physical oceanography"
1929 John Stanley Gardiner "for his contributions to oceanography"
1930 Johannes Schmidt "for his conduct of numerous oceanographic expeditions, his investigations of the life of eels, and the investigations of numerous problems connected with fishes, among which may be mentioned his work on fish genetics and geographic variation"
1931 Henry Bryant Bigelow
1932 Albert Defant "for his studies on atmospheric and oceanic circulation and his notable contributions to theoretical oceanography"
1933 Bjorn Helland-Hansen "for his studies in physical oceanography and especially for his contributions to knowledge of the dynamic circulation of the ocean"
1934 Haaken Hasberg Gran "for his contributions to knowledge of the factors controlling organic production in the sea"
1935 Martin Knudsen
1935 T. Wayland Vaughan "for his investigations of corals, foraminifer, and submarine deposits, and for his leadership in developing oceanographic activities on the Pacific coast of America"
1937 Edgar Johnson Allen
1938 Harald Sverdrup
1939 Frank Rattray Lillie
1942 Columbus Iselin II "for his studies of the Gulf stream system, for his leadership in the development of a general program of the physical oceanography of the North Atlantic, and for his distinctive direction of the Woods Hole Oceanographic Institution both in times of peace and war"
1946 Joseph Proudman "for his distinguished studies of the tides of the world"
1947 Felix Andries Vening Meinesz "for his contributions to oceanography, particularly by his invention of an apparatus for the determination of gravity at sea, by making many measurements of gravity over each of the great oceans, and by the utilization of these observations in interpreting the physical properties and behavior of the Earth's crust"
1948 Thomas Gordon Thompson "for his leadership in investigations of the complex chemistry of the ocean, with special attention to the waters of the north-east Pacific, Puget Sound, and San Juan Archipelago, and the Bering and Chukchi Seas"
1951 Harry A. Marmer "for his distinguished contributions in tidal surveys. His projects have made available to oceanographers accurate, long-period records for large areas where previously very little observational data were available. The program and work which he has originated ultimately will produce reliable conclusions on present-day tectonic processes and the rate of change in the quantity of water in the ocean"
1952 H. W. Harvey
1954 William Maurice Ewing
1955 Alfred C. Redfield
1959 Martin W. Johnson "for his outstanding leadership in biological and general oceanography. Among Dr. Johnson's contributions are explanations for two newly discovered acoustic phenomena in the sea. These explanations brought biologist and physicists together in a common interest, and introduced underwater acoustics as a prime tool for marine ecology"
1960 Anton Frederik Bruun "for his leadership in the study of the biology of the deep ocean"
1962 George Deacon "for his investigations of the hydrography of the southern ocean"
1963 Roger Revelle "for his contributions to the understanding of oceanic processes and the geology of the sea floor, and through his research, to the advancement of scientific oceanography throughout the world"
1965 Edward Crisp Bullard "for his significant investigations of the earth from its surface to its core"
1966 Carl Eckart "for his significant contributions to physical oceanography"
1969 Frederick C. Fuglister "for his stimulating and successful observations of the Gulf Stream and its vortices"
1972 Seiya Uyeda "for his contributions to the tectonic and thermal history of the earth and, most notably, the Sea of Japan"
1973 John H. Steele
1976 Walter Munk "for his outstanding experimental and theoretical research on the spectrum of motion in the oceans and the earth"
1979 Henry Stommel "for his work at sea, in the laboratory and by analyses through which he made major advances in understanding of ocean circulation and distribution of water masses"
1986 Wallace Smith Broecker "for his work on chemical exchange among the oceans, atmosphere, and solid Earth, making great contributions to understanding the role of the oceans in the Earth's carbon cycle and its climate"
1989 Cesare Emiliani "for masterful achievements using isotopic palaeotemperatures to establish the climatic history of the Pleistocene and for suggesting their relation to the Milankovitch orbital cycles"
1992 Joseph L. Reid "for his exploration and observation of the circulation of the world ocean, assembly of its many interacting parts with a lifetime of care, dedication, and insight"
1995 Victor Vacquier "for his discovery of the flux-gate magnetometer, and for the marine magnetic anomaly surveys that led to the acceptance of the theory of sea-floor spreading"
1998 Walter C. Pitman, III "for his fundamental contribution to the plate tectonic revolution through insightful analysis of marine magnetic anomalies and for his studies of the causes and effects of sea-level changes"
2001 Charles S. Cox "for his pioneering studies, both theoretical and instrumental, of oceanic waves, microstructure and mixing, and of electromagnetic fields in the ocean and in the seafloor"
2004 Klaus Wyrtki "for fundamental contributions to the understanding of the oceanic general circulation of abyssal and thermocline waters and for providing the intellectual underpinning for our understanding of ENSO (El Niño)"
2007 James R. Ledwell "for innovative and insightful tracer experiments using sulfur hexafluoride to understand vertical diffusivity and turbulent mixing in the open ocean"[3]
2010 Sallie Chisholm "for pioneering studies of the dominant photosynthetic organisms in the sea and for integrating her results into a new understanding of the global ocean"[4]
2013 David M. Karl "For leadership in establishing multi-disciplinary ocean-observing systems, for detection of decadal regime shifts in pelagic ecosystems, and for paradigm-shifting insights on biogeochemical cycles in the ocean."[5]
2018 Dean Roemmich
