Marine Sediment Cores from Southern Maryland

Detailed Description

A USGS marine sediment core from southern Maryland. The changes in deposition at the PETM are clearly apparent in the core as it changes abruptly from dark sand (lower right side of box is oldest) to lighter clay (upper left side of box is youngest), indicating sudden environmental changes associated with a large pulse of atmospheric carbon.
