Holocene sea‐level reconstruction in the Young Sound region, Northeast Greenland
Abstract A relative sea‐level curve over the Holocene is constructed for the Young Sound region in northeastern Greenland. The reconstruction is derived by dating the heights of raised beach ridges in coastal plains using optically stimulated luminiscence (OSL), and by dating palaeoterrestrial surfa...
