Fladen Grounds in the North Sea are the location for this collection of multibeam echosounder backscatter imagery. The data were collected during two research surveys aboard the RV Cefas Endeavour in April and November 2015. It captures seafloor conditions within six experimental boxes at three time points: before, immediately after, and eight months after a controlled fishing impact.
Use Cases
- Quantifying changes in seafloor backscatter intensity based on before/after impact imagery.
- Comparing habitat recovery rates between treatment and control areas based on the experimental design.
- Mapping seafloor substrate types and their disturbance based on acoustic backscatter patterns.
- Training models to detect fishing impact signatures based on time-series acoustic imagery.
Strengths
- Data collection follows a controlled experimental design with three treatment and three control boxes.
- Time-series data includes three distinct time points: before impact, immediately after, and eight months after.
- Surveys were conducted using a named research vessel, the RV Cefas Endeavour.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file size are unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
