Dye 3 trapped gas isotopic analyses covering abrupt warming episodes during last glacial period
Gas analyses were measured to reconstruct the 15Nitrogen/14Nitrogen (d15N) anomaly associated with the abrupt warming episodes better known as the Dansgaard-Oeschger (DO) events. In addition to the d15N analyses, we measured the elemental composition of Oxygen, Nitrogen and Argon in order to assess...
