Scientific american carbon dating
Carbon-14 has a half-life of 5,730 ± 40 years— during the succeeding 5,730 years.
Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon.
(Hint: It¿s not just carbon-dating anymore.) These days hardly a week goes by without important discoveries concerning the history of life on Earth making headlines.Though this dilution effect is well-known, its precise scale under different emissions scenarios was not, until now.Geologists, paleontologists and archaeologists have pieced together a fairly detailed account of how Earth and its inhabitants evolved.The World Ocean Circulation Experiment (WOCE) The World Ocean Circulation Experiment (WOCE); at the Woods Hole Oceanographic Institution's NOSAMS Facility.Measuring carbon in the Pacific and Indian Ocean to understand better the processes of ocean circulation.
Radiocarbon decays slowly in a living organism, and the amount lost is continually replenished as long as the organism takes in air or food.
