Abstract:
Sediment cores at sites J1002 awere collected from the Chilean Margin during D/V JOIDES Resolution Expedition 379T (JR100) in 2019. Sedimentary U/Th derived from natural gamma radiation data were collected during the expedition. U/Th was further used as a non-quantitative indicator of redox conditions of the sediments.
