Southern Ocean Sediment Trap Data with 40 Trace Metals, 2010-2019

40 trace metals and isotopes (TEIs) were analyzed from sinking particle samples collected at the Southern Ocean Time Series (SOTS) 1000 m depth sediment trap between 2010 and 2019. The dataset, published by the Australian Ocean Data Network, includes TEI concentrations, calculated elemental fluxes, and derived lithogenic particle fluxes for key tracers like Al, Fe, Ti, and Th. These results were used to estimate seasonal and interannual lithogenic particle flux in the subantarctic Southern Ocean south of Australia.

Use Cases

• Modeling dust deposition in the subantarctic Southern Ocean based on derived lithogenic particle fluxes.
• Examining seasonal and interannual variability in particle composition and sources using the multi-tracer lithogenic flux data.
• Assessing anthropogenic influences on marine particles using the included V and Pb tracer concentrations.
• Contextualizing particle flux estimates with satellite data and trajectory reanalysis as described in the publication.

Strengths

• Covers a 9-year time series from 2010 to 2019, providing long-term temporal context.
• Includes data on 40 trace metals and isotopes (TEIs), expanding on prior sinking particle flux data.
• Provides multiple iterations of lithogenic flux calculations for key tracers (Al, Fe, Ti, Th) and their mean values.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
