Research/Special Interests

Dr. Seminack's research deals with analyzing the geologic framework of coastal environments, specifically the barrier islands along the U.S. Atlantic coast. He is especially interested in storm impacts on barrier islands and tidal inlet dynamics. He focuses on reconstructing former tidal inlets along barrier islands using a multi-proxy approach. Techniques that he employs include the analysis of aerial photography and historic nautical charts, remote sensing, geophysical surveying, sediment coring, and geochronology. His other areas of interest are climate change, sea-level change, and ancient coastal environments in the rock record.
