The Birdsall-Dreiss Distinguished Lecturer honorees are named by this Division, along with the O.E. Meinzer Award, the George Burke Maxey Distinguished Service Award, the Kohout Early Career Award, and the Hydrogeology Division Student Research Grant Awards.

Karst  [ description ]

New Division as of October 2014.
The study of karst terranes necessarily involves a wide variety of subjects and specialties, spanning almost every division in GSA and scientific disciplines outside of GSA’s purview. These include geology, biology, microbiology, soils, environmental geology, engineering, geology, geochemistry, geophysics, structural geomorphology, archeology, urban planning, climatology, paleoclimatology, meteorology, hydrology, speleology, and even planetary studies. Comprehensive karst studies also can require the assistance of cave explorers and mappers, cave divers, mathematicians, modelers, and computer programmers. In all cases, practitioners in each discipline bring with them their own experiences, perspectives, insights, tools, and scales of reference.
