G.K. Gilbert Award

Nomination deadline: February 29, 2024January 15, 2023

Nominations for the 2024 Gilbert Award are now open. Nominations should include a cover letter detailing the accomplishments of the nominee, up to three supporting letters from colleagues, and a current CV. Electronic submissions can be emailed to Marisa Palucis at marisa.c.palucis@dartmouth.edu (past-PGD chair).

The G. K. Gilbert Award will be considered annually in accordance with the bylaws of the Society. The award will be made for outstanding contributions to the solution of a fundamental problem(s) of planetary geology in its broadest sense, including planetary geology, geochemistry, mineralogy, petrology, and tectonics, geophysics, and the field of meteoritics. Such contributions may consist either of a single outstanding publication, or a series of publications that have had great influence on the field. The award is named for G. K. Gilbert, who over one hundred years ago clearly recognized the importance of a planetary perspective in solving terrestrial geological problems.

The award consists of an engraved plaque and an appropriate certificate, which is recommended by the management board of the Division, and approved by the GSA Council. A person selected by and familiar with the Recipient's work presents a citation reviewing the contributions of the Recipient.

Congratulations to Dr. Candice Joy Hansen-Koharcheck of the Planetary Science Institute, the 2023 Gilbert awardee!
