Using ice cores, researchers can obtain multiple records for paleoclimate. However, ice cores from deep drilling projects recover limited amount of ice, prohibiting the paleoclimate studies that need a large amount of ice such as analyzing isotopes of trace gases and metal elements in the ice. Because glaciers outcropped at the surface in blue ice areas (BIAs) allow collection of extensive amount of samples, the BIAs serve as an alternative to the conventional deep ice core drilling sites. However, most of the ice stratigraphy in BIAs is disturbed due to the complicated ice flow, which hinders to figure out the chronostratigraphy of the ice. Here, we report a simple chronostratigraphy of ice from Larsen BIA, Antarctica. Based on dust bands on the surface of the ice and ground penetration radar (GPR) survey, the chronostratigraphy of the studied Larsen BIA shows a monotonic increase of ages in the mid- to downstream side ice. The δ18Oatm and δ2Hice values of Larsen ice show a very typical range of the last glacial termination. Correlation of δ18Oice, δ18Oatm, and CH₄ records of Larsen ice with existing ice core records indicates that the gas and ice ages ranges are 9.2–23.4 and 5.6–24.7 ka BP, respectively. In addition, radiometric 81Kr dating confirms the constrained ages within analytical uncertainty. Our study may contribute to future research of the paleoclimate during the last glacial termination via the Larsen ice.
