Radiocarbon assays of submerged peat and shell beds in the northern Gulf of Mexico interpreted here to reconstruct sea level change over time. The vertical axis shows depth below modern sea level; the horizontal axis shows calibrated years before 1950 AD. The red curve is a best-fit line for rising sea level based on radiocarbon assays.
