The stratigraphic record is replete with evidence that ocean shorelines have advanced and retreated throughout geologic time. UTIG researchers are involved in several projects to better understand changes in the Earth’s climate and related fluctuations in sea level through geologic time. Sediment cores collected by UTIG scientists beneath the seafloor in the Gulf of Mexico and offshore New Jersey document these fluctuations through study of their sedimentary structures, microfossils, geochemistry and mineralogy, as well as associated seismic data. By understanding changes in past climate, researchers provide data essential to analyzing both natural and human-induced changes in our current climate system.
