英文简介	Ten shallow ice cores 0.9-1.1 m deep were collected with a 7.25 cm diameter Kovacs Mark III coring system (http://www.kovacsicedrillingequipment.com). Cores were collected and processed adjacent to the core sites on 11 July and 12 July between 14:00 and 21:00 local time. Core stratigraphy observations recorded in field notes include the presence of liquid water, ice lenses, and air bubbles. Natural breaks were used to separate the cores into individual segments. Each segment's length and diameter were measured to the nearest 0.1 cm with a calliper and weighed to the nearest 0.1 g on an Acculab digital scale to determine the ice density of each segment. The natural break segmentation yielded a 13 ± 6 cm mean sampling interval. Individual segments ranged from 3 to 40 cm in length.
