Dr. Antonio "Tony" Rodriguez, a sedimentologist and stratigrapher, explores how intertidal oyster reefs are responding to sea-level rise. Drawing on decades of field-based research, he discusses sedimentary processes, carbon burial, and the changing dynamics of coastal habitats. His retrospective approach combines geochronologies, seismic data, and remote sensing to understand how oyster reefs—and the ecosystems they support—will fare in a warming world.
