Scientists discover secret of more precise carbon dating

An international team of researchers says that a Japanese lake offers great prospects for carbon dating.

A number of sediment cores and plant fossils from Japan’s Lake Suigetsu will provide scientists with more accurate benchmarks for carbon dating the oldest objects, according to a statement from Oxford University’s Radiocarbon Accelerator Unit.

Professor Christopher Ramsey, his doctoral student Richard Staff and chemist Dr Fiona Brock worked with the NERC facility at East Kilbride, Scotland, and Groningen in the Netherlands to extract the lake’s radiocarbon record as part of an international research team led by Professor Takeshi Nakagawa of Newcastle University, whose main focus has been studying cores for clues about past climate and environmental change.
