Australia's western, northern, and eastern continental margins were sampled at over 350 locations between 2007 and 2014. The dataset includes measures of organic matter source, concentration, and bioavailability in seabed sediments. It was compiled by researchers and published in Marine and Freshwater Research in 2017.
Use Cases
- Modeling benthic nutrient fluxes based on sediment oxygen demand (SOD) and total sediment metabolism (TSM) measurements.
- Analyzing organic matter sources and bioavailability based on δ13C, δ15N, C:N ratios, and chlorin indices.
- Mapping seabed organic carbon concentration relative to water column productivity using %TOC and OC:SA data.
- Investigating nitrogen fixation and recycling in marine food webs based on δ15N values.
Strengths
- Over 350 sampling locations across Australia's continental margins.
- Data collection spanned 7 years (2007-2014) from federal government surveys.
- Includes multiple parameters for organic matter source, concentration, and bioavailability.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
