Seagrass Imagery from Benthic Video Surveys in Tasmanian Waters

Approximately 400 benthic video samples collected around the Furneaux Islands, Tasmania, to map seagrass extent and composition. Imagery was captured using a Benthic Observation Survey System (BOSS) and stereo-uBRUV platforms and annotated via the SQUIDLE+ platform. The project contributed to a national standard operating procedure for seagrass mapping using optical remote sensing.

Use Cases

• Validate and calibrate remote sensing outputs for seagrass extent based on field imagery.
• Assess population structure and species composition of seagrass beds based on annotated photoquadrats.
• Estimate blue carbon storage potential of temperate seagrass habitats based on mapped extent and ecological data.
• Develop habitat maps by integrating field validation imagery with satellite data as referenced in the associated dataset.

Strengths

• Field validation involved approximately 400 sample locations using standardized benthic video platforms.
• The methodology contributed to a published national Standard Operating Procedure for Seagrass Mapping.
• Imagery annotation was conducted using the specialized SQUIDLE+ platform.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
