Government Digital Service collected biological and physical parameters from sediment profile images of the seabed. Data were acquired from six experimental boxes during a fishing impact recovery survey in the Fladen Grounds. Measurements were taken at three time points before, immediately after, and eight months after impact during research surveys in April and November 2015.
Use Cases
- Model benthic habitat quality recovery based on the Benthic Habitat Quality Index assessment.
- Analyze changes in sediment physical structure based on apparent redox potential discontinuity (aRPD) layer and penetration depth.
- Track biological recovery of infauna communities based on presence of infauna and tubes.
- Compare treatment and control effects on seabed surface roughness.
Strengths
- Data were collected at three distinct time points (before, immediately after, and eight months after impact) allowing for temporal analysis.
- Experimental design includes three treatment and three control boxes for comparative assessment.
- Parameters include both biological (infauna presence) and physical (aRPD, penetration depth) measurements.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
