Accelerator mass spectrometry is a method of radiocarbon analysis where atoms of Carbon 14 contained in a sample are counted. Applications include dating of sedimentary deposits and detailed studies of circulation and carbon cycling in the modern ocean. (Photo by Tom Kleindinst, Woods Hole Oceanographic Institution)
