The International Union for Quarternary Research has established the Sir Nicholas Shackleton Medal in recognition of the many contributions of Nick Shackleton, a giant in the field of Quaternary science. The medal will be awarded once every four years to an outstanding young Quaternary scientist, chosen by his or her peers and evaluated by a blue-ribbon committee of distinguished scientists. The medal, INQUA’s first, honours Nick’s distinguished career in Quaternary geochronology and paleoclimatology, which spanned 40 years and was based on isotopic studies of deep-sea sediment. Shackleton was showered with honors by his peers and the wider scientific community, thus a medal in his name seems appropriate and necessary. Nick served INQUA for 12 years, first as a Vice-President, then, from 1998 to 2003, as President, and most recently as Past-President.
