Nature World: Researchers have used radiometric krypton-dating to find the age of ancient Antarctic ice. The new technique can be used to hunt and date old ice samples.
Finding old ice samples is important because it helps scientists construct and fine-tune ancient climate models. The latest krypton-based dating technique shows that the ice from Taylor Glacier in Antarctica is around 120,000 years old.
Just so that we are clear, researchers here are using krypton- the noble gas and not kryptonite, which...
