A 2000-year annual record of snow accumulation rates for Law Dome, East Antarctica

These data were collected from the drilling site at Dome Summit South (DSS) on Law Dome in East Antarctica. The DSS site is on Law Dome, a prominent ice dome located about 120 km from Casey Station. The site receives a high rate of snow accumulation which helps create a very detailed climate record. The DSS_2000-year annual snow accumulation record is the annual snow accumulation record for the "DSS" Law Dome ice core with extensions (e.g. as described in Roberts et al., 2015) from overlapping ice cores which are dated by comparing multiple chemical species.

本数据集采集自东南极洲（East Antarctica）劳穹（Law Dome）南侧穹顶（Dome Summit South，DSS）的钻探点位。DSS点位位于劳穹之上，劳穹是一处距离凯西站（Casey Station）约120公里的知名冰穹。该区域积雪积累速率较高，有助于形成极为详尽的气候记录。DSS_2000年积雪年积累序列，是针对“DSS”劳穹冰芯（ice core）的年积雪积累记录，其延伸数据源自经多化学组分比对定年的重叠冰芯，相关延伸方法详见Roberts等人2015年的研究。
