Accelerator mass spectrometry carbon dating

More information
The amount of carbon dioxide in the atmosphere today is higher than that at any time in the last , years figure 1. Carbon dioxide in the atmosphere exchanges dynamically with carbon dissolved in oceans and stored in plants and soils on land figure 3. Changes in atmospheric CO 2 clearly must be explained by repartitioning of carbon among these three reservoirs. More research is necessary to explain past changes in CO 2 and to predict how CO 2 , given continued fossil fuel emissions, will change in the future.

Weizmann scientists date Santorini eruption with modern olive branch - The Jerusalem Post

University of Utah researchers developed a new weapon to fight poachers who kill elephants, hippos, rhinos and other wildlife. By measuring radioactive carbon deposited in tusks and teeth by open-air nuclear bomb tests, the method reveals the year an animal died, and thus whether the ivory was taken illegally. It was published online the week of July 1 in the journal Proceedings of the National Academy of Sciences. Not only can the method help wildlife forensics to combat poaching, but "we've shown that you can use the signature in animal tissues left over from nuclear weapons testing in the atmosphere to study modern ecology and help us learn about fossil animals and how they lived," says Cerling, a distinguished professor of geology and geophysics, and biology at the University of Utah.

Overview of Mass Spectrometry for Protein Analysis

Accelerator mass spectrometry AMS is a form of mass spectrometry that accelerates ions to extraordinarily high kinetic energies before mass analysis. The special strength of AMS among the mass spectrometric methods is its power to separate a rare isotope from an abundant neighboring mass "abundance sensitivity", e. This makes possible the detection of naturally occurring, long-lived radio-isotopes such as 10 Be, 36 Cl, 26 Al and 14 C. AMS can outperform the competing technique of decay counting for all isotopes where the half-life is long enough.
