Envision Mapping Ltd conducted a survey of the Moray Firth candidate Special Area of Conservation within the 30-meter contour. The project used a RoxAnn acoustic ground discrimination system and a GeoSwath interferometric swath bathymetric system to map sediment features and biota, with biotopes classified using the Marine Habitat Classification system (Connor et al. 2004). The survey achieved 100% coverage with the swath system or a minimum track spacing of 80 meters over priority areas.
Use Cases
- Classifying benthic biotopes based on acoustic remote sensing and video sampling data.
- Mapping seabed sediment features within a defined bathymetric contour.
- Analyzing the distribution of marine biota using a standardized habitat classification system.
- Validating acoustic ground discrimination data with physical grab and video samples.
Strengths
- Survey achieved 100% coverage with the swath system or a minimum 80-meter track spacing in priority areas.
- Biotope classification follows the standardized Marine Habitat Classification system (Connor et al. 2004).
- Data collection combined multiple methods: acoustic remote sensing, grab sampling, and video analysis.
Limitations
- Survey coverage was incomplete in areas outside the designated priority zones.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and dataset size are unknown, which may limit suitability assessment.
