Four AGU members are among the 18 individuals the U.S. National Academy of Sciences (NAS) will honor during its 150th annual meeting in April. William J. Borucki, space scientist at the NASA Ames Research Laboratory and science principal investigator for the Kepler Mission, is the recipient of the Henry Draper Medal “for his founding concept and visionary leadership of Kepler.” John Gosling, senior research associate in the Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder, and retired laboratory fellow at Los Alamos National Laboratory, will receive the Arctowski Medal. Gosling was selected for his work on the generation of energetic solar events, including distinguishing solar flares and coronal mass ejections. David Karl, professor of oceanography at the University of Hawai‘i, Mānoa, is the recipient of the Alexander Agassiz Medal. NAS notes Karl's leadership in establishing multidisciplinary ocean-observing systems, detecting decadal regime shifts in pelagic ecosystems, and insights on biogeochemical cycles in the ocean. J. William Schopf, distinguished professor of paleobiology at the University of California, Los Angeles, is the recipient of the NAS Award in Early Earth and Life Sciences, presented in 2013 with the Charles Doolittle Walcott Medal. Schopf is being honored for his studies of microscopic fossils that represent the earliest forms of life on Earth and for leadership of large collaborative research groups.
