The landforms of Long Island are young and dynamic, shaped by glaciers, wind, tides, and storms. This makes them ideal targets for study using a combination of recent and historical maps and aerial images along with geophysical techniques such as ground-penetrating radar and optically stimulated luminescence dating. This combination of surface and subsurface mapping and dating allows us new insights into Long Island’s hilly moraines, its rapidly changing barrier islands, and its parabolic dunes—from the active Walking Dunes of Napeague to the Grandifolia Dunefield of Baiting Hollow that formed in response to winds blowing from the late Pleistocene glaciers.
Dan Davis has been a member of the faculty at Stony Brook since 1986 and is now Chair in the Department of Geosciences. His research in structural geology and tectonics has focused on theoretical and laboratory studies related to the mechanics of mountain building. Other areas of research include geological aspects of nuclear test-ban monitoring and the application of geophysical techniques to glacial and post-glacial geology. His public outreach spans astronomy as well as geology, and includes co-authorship (with Guy Consolmagno) of the book Turn Left at Orion, Hundreds of Night Sky Objects to See in a Home Telescope──and How to Find Them, published by Cambridge University Press
