Fortymile River Cosmogenic Isotope and Luminescence Data Collected 2016-2019

This dataset is four tables containing cosmogenic beryllium-10 and aluminum-26 concentrations and related data, as well as infrared stimulated luminescence data, from samples collected at 21 sites along the Fortymile River in eastern Alaska and Yukon, Canada between 2016 to 2018, and processed between 2016 and 2019. The file "burialDating_siteLocations_fortymile_bender.csv" contains site locations in the NAD83 reference frame, and depositional ages or erosion rates computed from raw data contained in the other files. All files are linked by the "site_id" field.

本数据集包含4张数据表，涵盖采自美国阿拉斯加州东部及加拿大育空地区四十英里河（Fortymile River）沿岸21个采样点的宇宙成因铍-10（cosmogenic beryllium-10）、铝-26（aluminum-26）浓度及相关配套数据，同时包含红外释光（infrared stimulated luminescence）数据。所有样品于2016至2018年间采集，样品处理工作则在2016至2019年间完成。文件"burialDating_siteLocations_fortymile_bender.csv"包含NAD83参考框架下的采样点坐标，以及基于其他文件中原始数据计算得到的沉积年龄或侵蚀速率。所有数据表均通过"site_id"字段建立关联。
