Particle Size Analysis and organic carbon content data from marine sediment samples collected in the Trevose Box off southwest England in April 2023. The dataset captures conditions before and after experimental scallop dredging and beam trawling, funded by DEFRA and led by Bangor University. Samples were taken using a 0.1 m2 Day grab and analyzed for sediment properties and carbon content.
Use Cases
- Analyze Particle Size Analysis data to assess sediment disturbance from scallop dredging and beam trawling.
- Model the relationship between organic carbon content and fishing intensity ('Times fished') across sampled plots.
- Compare sediment properties and carbon levels between 'Before' and 'After' fishing conditions within the Trevose Box management area.
- Investigate seabed carbon dynamics using data from homogenized grab samples and 1 cm interval core slices.
Strengths
- Data collected from a controlled environment within a seasonal fishing closure (Trevose Box), reducing confounding effects.
- Includes paired 'Before' and 'After' samples for experimental fishing impacts across two distinct gear types.
- Sampling design minimized differences in depth, seabed habitat, and sediment type between experimental plots.
Limitations
- Sample size is limited to two plots and a single sampling week, restricting statistical power and generalizability.
- Unknown row count, column structure, and file formats hinder immediate assessment of data volume and usability.
- Geographic scope is restricted to one management area off southwest England, limiting broader regional insights.
