In this paper, we present and discuss the pre-Holocene dust profile of the Greenland Ice Sheet Project 2 (GISP2) ice core retrieved from central Greenland measured using laser-light scattering (LLS) from ice and compare it with the electrical conductivity method and oxygen isotope profiles. We describe how we dated the pre-Holocene ice using the annual dust peaks observed with LLS (starting from the accepted chronology to 2250 m) and obtained a chronology in substantial accord with the gas-age dating of the ice. We also show that the GISP2 ice core penetrated the Eemian and that a record of a 10.2-kyr penultimate glaciation is present in the GISP2 core. ¿ 1997 American Geophysical Union
