Surficial marine sediment samples from over 350 locations across Australia's western, northern, and eastern continental margins collected during federal government surveys from 2007 to 2014. Parameters analyzed include organic matter source, concentration, and bioavailability metrics. The dataset was compiled by researchers including Lynda Radke and published in 2017.
Use Cases
- Modeling nutrient fluxes between seabed and water column based on sediment oxygen demand and total sediment metabolism.
- Assessing regional organic matter sources and quality based on stable isotope (δ13C, δ15N) and chlorin indices.
- Correlating sediment organic carbon content with water column productivity metrics like MODIS data.
- Investigating the role of nitrogen fixation in marine productivity using δ15N values from the Timor Sea.
Strengths
- Samples from over 350 locations provide broad spatial coverage of Australia's continental margins.
- Data collection spanned 7 years (2007-2014), offering a temporal baseline.
- Analysis includes multiple organic matter parameters (source, concentration, bioavailability).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
