The James B. Macelwane Medal is given annually to three or up to five honorees in recognition for “significant contributions to the geophysical sciences by an outstanding early career scientist.”

Established in 1961, the Macelwane Medal was renamed in 1986 in honor of former AGU president James B. Macelwane (1953–1956). Renowned for his contributions to geophysics, Macelwane was deeply interested in teaching and encouraging young scientists.  James N. Brune was the first recipient of this medal.
