Organic carbon from the Efri Haukadalsa river, Iceland

Bulk carbon concentrations, organic carbon stable isotopic ratios, and organic carbon radiocarbon measurements for fluvial deposits, suspended sediments, and a tree fragment from the Efri Haukadalsá river catchment in Iceland (collected in August 2016).本数据集包含冰岛埃夫里·豪克达勒萨河（Efri Haukadalsá）流域的河相沉积、悬浮沉积物以及一处树木残体的总碳浓度、有机碳稳定同位素比值与有机碳放射性碳测量数据，样品采集于2016年8月。
