Current Professional and Scholarly Interests

    Dr. Riggs is a coastal and marine geologist who has been doing research on modern coastal systems since 1964 and has been on the faculty at East Carolina University since 1967. His research extends from inland river, lake, and pocosin environments, to estuarine and barrier island systems, and seaward across the continental shelf. His areas of interest lie in sedimentation, Quaternary and Tertiary stratigraphy, coastal and mineral resources, and their inter-relationship with the development of human civilization. Dr. Riggs has been actively involved in numerous technical coastal and mineral resource issues at the Federal, State, and local levels that included appointments to many commissions, task forces, panels, and committees. These appointments, as well as many of his publications, have dealt directly with integrating scientific understanding and utilization and management of various coastal systems including such critical issues as climate change and sea-level rise, shoreline erosion and land loss, hazard zone delineation, inlet dynamics, water quality, and habitat preservation (i.e., hardbottom reefs, salt marshes, maritime forests, etc.), and natural resources (i.e., water, beach nourishment sand, as well as resources critical for energy, food production, building, etc.).

    Dr. Riggs has carried out long-term research programs in the following general topics both in North Carolina, throughout the US Atlantic coast, and in many other coastal regions of the world. These projects were funded by many Federal and State agencies including the US National Science Foundation, NOAA Sea Grant, NOAA National Undersea Research Program, Environmental Protection Agency, Geological Survey, Department of Defense, Minerals Management Service, and the NC Departments of Water Resources, Geological Survey, Water Quality, State Parks, and Transportation.

The general research topics that he is actively working on include the following.
1. Origin and evolutionary development of modern coastal systems since the last glacial maximum, the dynamic processes of change and their impact upon human development
2. Origin, evolutionary development, and dynamics of coastal plain riverine and pocosin wetland systems
3. Quaternary and upper Tertiary stratigraphic record of changing global climate, sea level, and sedimentologic responses
4. Estuarine water quality: interaction between the sediment regime, chemical pollutants, and benthic community structure
5. Interaction between the underlying geologic framework, storm dynamics, sediment processes, and the integrated response of the coupled barrier island, shoreface, and continental shelf systems
6. Evolution of continental shelf hardbottom habitats and their relationship to benthic community structure and fish recruitment
7. Bioerosion, sediment production, and storm dynamics of continental shelf hardbottoms
8. Geology of continental shelf resources including beach nourishment sand, ground water, and other authigenic minerals (i.e., phosphate, glauconite, carbonates, etc.)
