1990 NICHOLAS SHACKLETON
Dr. Nick Shackleton is the thirteenth recipient of the award, and is being recognized for his fundamental contributions in the division of marine geosciences. Dr. Shackleton is reader at the University of Cambridge, director of the sub-department of Quaternary Research (Cambridge), Official Fellow of Clare Hall (Cambridge), and Senior Research Associate of Lamont-Doherty Institute (USA). He is a Fellow of the Royal Society of London (1985), and of the American Geophysical Union (1990), and has been the recipient of a number of scientific awards. Dr. Shackleton's research for much of the past two years has focused on detailed oxygen isotope records in the Panama Basin (ODP Site 677). The reason for devoting so much time to this particular site is that it has proved a unique opportunity to test the Milankovitch theory over the whole Pleistocene and the late part of the Pliocene - unique in the amount of detail preserved, in the types of information available, and in the long uninterrupted time-span represented. This is making it possible to calibrate the geological timescale and, among other things, learn more about the workings of the global climate system. Dr. Shackleton is receiving the Huntsman Medal in recognition of his innovative work on paleoceanography and the development of oxygen isotopic stratigraphy.
