Maintenance and Update Frequency: asNeeded Statement: This is a data compilation. Data were sourced from the published literature, from paper appendices, PANGEA, and NOAA databases, and in some cases personal communication from the authors. The compilation builds on that produced by Kohfeld, K. E., & Ridgwell, A. (2009). Glacial-Interglacial Variability in Atmospheric CO2. Geophysical Research Series, 187 (Surface Ocean-Lower Atmosphere Processes), 251–286. https://doi.org/10.1029/2008GM000845. This dataset is a compilation of published records of 230Thorium - normalised lithogenic and biogenic fluxes from the Southern Ocean. All age models and derived fluxes were taken as published. Lithogenic fluxes are based on 232Th concentrations. In some cases fluxes had to be derived from published data. LGM values for each core represent an average of observations between 28 - 18 ka BP and Holocene values represent an average of observations from 10 - 0 ka BP. Credit ARC Discovery Grant DP180102357 This dataset is a compilation of published records of 230Thorium - normalised lithogenic and biogenic fluxes from the Southern Ocean, south of 30S. All age models and derived fluxes were taken as published. Lithogenic fluxes are based on 232Th concentrations. Opal and carbonate fluxes are also included where available. In some cases fluxes had to be derived from published data. LGM values for each core represent an average of observations between 28 - 18 ka BP and Holocene values represent an average of observations from 10 - 0 ka BP. These data were collated as part of modelling study of the Southern Ocean during the LGM (Saini et al, Southern Ocean ecosystem response to Last Glacial Maximum boundary conditions, Submitted to Paleoceanography and Paleoclimatology, 2021)
