Abstract

Global sea level has fluctuated throughout Earth history. To understand sea level changes, it is important to identify and date ancient marine shorelines. This study focuses on the Last Interglacial period about 125,000 years ago, when global sea levels were roughly 20 feet higher than today. The project improves a dating method based on chemical changes in fossil shells and applies it to a range of global sites. A…
