Annual Layers at Siple Dome, Antarctica, from Borehole Optical Stratigraphy

Researchers gathered data on annual snow layers at Siple Dome, Antarctica, using borehole optical stratigraphy. This data set contains annual layer depths and firn optical brightness. The brightness log is a record of reflectivity of the firn, and peaks in brightness are interpreted to be fine-grained high-density winter snow, as part of the wind slab depth-hoar couplet. Data are available via FTP in ASCII text (.txt) format研究人员采用钻孔光学地层学（borehole optical stratigraphy）方法，在南极洲西波穹顶（Siple Dome）采集了年积雪层数据。该数据集包含年层厚度与粒雪（firn）光学亮度数据。亮度日志记录了粒雪的反射率，其中亮度峰值被解读为细粒高密度冬季积雪，属于风成板状雪-深霜对的组成部分。 数据可通过FTP以ASCII文本（.txt）格式获取
