Roosevelt Island Climate Evolution (RICE) ice core: The RICE17 chronology and accumulation record for the past 2700 years

A 2700-year annual timescale and accumulation history for the RICE (Roosevelt Island Climate Evolution) ice core from Roosevelt Island, Ross Sea region, West Antarctica.
The timescale was constructed by a combination of manual and automated annual-layer counting, and subsequently validated by volcanic and methane matching to the WAIS Divide ice core on the WD2014 chronology. It constitutes the top part of the Roosevelt Island Ice Core Chronology 2017, RICE17. […]

南极罗斯海地区罗斯岛RICE（罗斯岛气候演化）冰芯的2700年年度时间尺和积累历史。该时间尺通过手动和自动年度层计数相结合的方式构建，随后通过火山和甲烷匹配至WD2014年代学中的WAIS Divide冰芯进行验证。它构成了2017年罗斯岛冰芯年代学RICE17的上部部分。
