A.C. Redfield Lifetime Achievement Award
The Lifetime Achievement Award was first presented in 1994 to recognize and honor major, long-term achievements in the fields of limnology and oceanography, including research, education and service to the community and society. In 2004, the ASLO Board renamed the Lifetime Achievement Award in honor of Alfred C. Redfield. Redfield's biography was compiled by Dr. Peter Williams, who received the Redfield Award in 2009, and published in the December 2006 issue of the Limnology and Oceanography Bulletin.
Emphasis in selection is given to established aquatic scientists whose work is recognized for its importance and long-term influence. Candidates should have more than 25 years experience beyond the date of their most advanced degree. This award is open to pairs of individuals where joint work has been of a long-term, sustained collaborative effort.
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.
Dr. Stephen Carpenter (2019), in recognition of his remarkable contributions to the field of limnology and lake management; including major advances in our understanding of trophic cascades, eutrophication, regime shifts, fisheries sustainability, and social ecological systems via approaches that confront theory with large-scale collaborative experimentation, long-term lake surveys, community outreach, and education.
