DESCRIPTION OF DATA

This data repository contains the following datasets. We refer the user to the original manuscript (see above) and the text of the Supporting Information published alongside this manuscript for additional general information regarding the collection and generation of these data.

DATA TABLES FOR ALL CORE SITES

  • Kinsley et al. (2021) P&P - Data Tables for OC437-7-GC-37 core - v1: This Excel workbook contains all data used in the study for the OC437-7-GC-37 core site, taken by the R/V Oceanus during the 2007 Changing Holocene Environments of the Eastern Tropical Atlantic (CHEETA) cruise. This includes the age control and age model, biogenic %s, U-Th isotopic measurements, grain size distributions and endmember modeling, and 230Th-normalized flux data. All previously published data is noted as such and referenced.

  • Kinsley et al. (2021) P&P - Data Tables for OC437-7-GC-49 core - v1: This Excel workbook contains all data used in the study for the OC437-7-GC-49 core site, taken by the R/V Oceanus during the 2007 Changing Holocene Environments of the Eastern Tropical Atlantic (CHEETA) cruise. This includes the age control and age model, biogenic %s, U-Th isotopic measurements, grain size distributions and endmember modeling, and 230Th-normalized flux data. All previously published data is noted as such and referenced.

  • Kinsley et al. (2021) P&P - Data Tables for OC437-7-GC-68 core - v1: This Excel workbook contains all data used in the study for the OC437-7-GC-68 core site, taken by the R/V Oceanus during the 2007 Changing Holocene Environments of the Eastern Tropical Atlantic (CHEETA) cruise. This includes the age control and age model, biogenic %s, U-Th isotopic measurements, grain size distributions and endmember modeling, and 230Th-normalized flux data. All previously published data is noted as such and referenced.

  • Kinsley et al. (2021) P&P - Data Tables for ODP 108-658C core - v1: This Excel workbook contains all data used in the study for the ODP 108-658C core site, taken by the R/V JOIDES Resolution off Cap Blanc, Mauritania during Ocean Drilling Program Leg 108. This includes the age control and age model, biogenic %s, U-Th isotopic measurements, grain size distributions and endmember modeling, and 230Th-normalized flux data. All previously published data is noted as such and referenced.
