G. Evelyn Hutchinson Award


The G. Evelyn Hutchinson Award has been presented annually since 1982 to recognize excellence in any aspect of limnology or oceanography. The award is intended to symbolize the quality and innovations toward which the society strives and to remind its members of these goals. In lending his name to the award, Hutchinson asked that recipients be scientists who had made considerable contributions to knowledge, and whose future work promised a continuing legacy of scientific excellence.


Emphasis in selection will be given to mid-career scientists for work accomplished during the preceding 5-10 years. Preference will be given to candidates within 25 years of the receipt of their most advanced degree. Exceptional cases may be considered. This award is for an individual.


Each nomination must be supported by a letter (not to exceed two pages) on qualifications. Ideally this letter should include statements that would form the basis of the citation and the presentation speech at the ASLO meeting. The nomination package may also include a list of important publications and other pertinent information, but in total this package shall be no more than 3 pages. The nomination should also be supported by 3 letters of endorsement of no more than 1 page each. These letters should indicate the breadth of support for the nominees and the perspectives of different individuals to clearly indicate the breadth of contributions of the nominee.
