Radiocarbon dates from ice-edge ice-entombed tundra plants around the Orion and Serpens ice complexes, northern Baffin Island, Canada in 2018 and 2019
Radiocarbon dates on formerly ice-entombed tundra plants collected within 1 meter (m) of the current ice margin of rapidly receding ice caps on northern Baffin Island to test the concept of volcanic forcing on episodic ice cap expansion during the Common Era. The goal of this project is to examine t...
