RICE ice core calcium data for the last glacial period (83-26 ka BP)

Roosevelt Island Climate Evolution (RICE) ice core calcium (Ca) data, measured using continuous flow analysis (CFA), covering last glacial period 83000-26000 years BP is presented here. RICE is a 764-m long ice core retrieved from Roosevelt Island, a coastal dome in the vicinity of Ross Sea, West Antarctica. The measurements were made at Centre for Ice and Climate, University of Copenhagen, Denmark in 2015 and posses annual resolution. A three-point calibration was used for the measurements.

本数据集公开了采用连续流分析（continuous flow analysis, CFA）测得的罗斯福岛气候演化（Roosevelt Island Climate Evolution, RICE）冰芯钙（Calcium, Ca）数据，其时间覆盖末次冰期83000至26000年前（BP）。RICE冰芯为取自西南极洲罗斯海附近沿岸穹丘罗斯福岛的764米长冰芯。该测量工作于2015年在丹麦哥本哈根大学冰与气候研究中心完成，数据具备年分辨率，测量过程采用了三点校准法。
