Surficial seabed samples from over 350 locations across Australia's western, northern, and eastern continental margins collected during federal government surveys between 2007 and 2014. The dataset includes parameters for organic matter source, concentration, and bioavailability, analyzed by researchers from the Australian Ocean Data Network. The study links sediment properties to water column productivity and makes inferences about governing biogeochemical processes.
Use Cases
- Modeling organic matter cycling in coastal sediments based on parameters like δ13C, δ15N, and C:N ratios.
- Assessing regional seabed organic carbon concentration and bioavailability using %TOC, OC:SA, and chlorin indices.
- Investigating links between water column productivity and benthic processes using sediment oxygen demand (SOD) and total sediment metabolism (TSM) data.
- Studying the role of nitrogen fixation in marine productivity using δ15N values from the Timor Sea region.
Strengths
- Over 350 sample locations provide spatial coverage across three major Australian continental margins.
- Analysis includes multiple parameters for organic matter source, concentration, and bioavailability, allowing for integrated study.
- Data collection spanned seven years (2007-2014), providing a temporal baseline for the region.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the specific survey locations and time period.
