With the advent of accelerator-mass spectrometer (AMS) radiocarbon dating, it is now possible to date these paleolacustrine sediments.

AMS dates were obtained on sediment cores from the Bonneville, Franklin, and Lahontan Basins.

In 2001, ESS/CGECR researchers Ellen Druffel, John Southon and Susan Trumbore were awarded million by the W. Keck Foundation for the development of an accelerator mass spectrometry (AMS) facility – the Keck-Carbon Cycle AMS facility - for radiocarbon measurements in support of carbon cycle research at University of California, Irvine.

Douglas Kennett, professor of anthropology at Penn State, recently confirmed a correlation between the Maya Long Count calendar and the European calendar by AMS dating small slivers of wood from a carved Maya lintel.An accelerator then increases the kinetic energy of the carbon ions to 10-30 million electron volts and moves them through a tube where a powerful electromagnet makes them change direction. Because carbon-14 decays over time, the amount of it in a sample indicates the age of the sample.How much their path bends depends on their mass: Lighter ions bend more. Penn State will soon be home to an accelerator mass spectrometer (AMS) that will allow researchers all over the country to do high-precision carbon dating to address questions about Earth's past and present.An example of precision dating is the Dead Sea Scrolls.Current research areas range from geology to marine biology and many more.
