Robert Marvinney has been with the Maine Geological Survey since 1987, and has been Director of the survey and State Geologist since 1995. He runs a multifaceted agency with programs in geologic mapping, aquifer delineation, groundwater quality, coastal geology, and geologic hazards. His current focus is on public policy as it relates to geological issues - primarily ground water resources and coastal geological processes. Prior to the Survey, Marvinney spent several years in Houston working for a major oil company.
Most of his graduate studies at Syracuse University focused on the geology of northern Maine, culminating in his Ph.D. summarizing bedrock mapping in Silurian and Devonian metasedimentary rocks. He continues to work on bedrock mapping projects in central and southern Maine.
Marvinney is Past President of the Association of American State Geologists (2005) and co-chairs the Association's Water Resources Policy Committee.
