126 samples of seabed sediment TCO2 flux and pool data collected by Geoscience Australia in Jervis Bay, NSW. Surveys were conducted in 2007, 2008, and 2009 using the MV Kimbla, focusing on a 3x5 km grid and additional habitat types. The dataset provides biogeochemical measurements for surface sediments from depths of approximately 0 to 2 cm.
Use Cases
- Modeling benthic carbon budgets based on TCO2 flux measurements.
- Characterizing seabed habitats through colocated biogeochemical and textural analysis.
- Studying the impact of ocean tides and wave-generated currents on sediment carbon pools.
- Mapping spatial variability of carbon fluxes within a defined survey grid.
Strengths
- 126 sediment samples provide a substantial dataset for analysis.
- Data collection spans multiple years (2007-2009) and includes a focused 3x5 km survey grid.
- Colocated sampling integrates biogeochemical, textural, and infauna data for environmental characterization.
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 and temporal bias inherent to the specific survey locations and periods.
