GSA Northeastern Section Meeting: Portland, Maine, USA

Geological Society of America

Boulder, Colo., USA: On 17-19 March, geoscientists from the northeastern U.S. and beyond will convene in Portland, Maine, to discuss new science, expand on existing science, and explore the unique geologic features of the region. The technical program covers a diverse set of geologic topics and processes, including applied geology; education; northeastern tectonics; Quaternary geology and climate; coastal, groundwater, and river processes; geological hazards; mineral resources; and the formation and evolution of Iceland.

Selected Highlights of the Scientific Program

The scientific program is composed of oral and poster presentations organized into symposia and themed and discipline sessions covering an array of research in the geosciences.
