Coastal Aquaculture Site Surveys in New Brunswick and Nova Scotia

March 2019 data from towfish and echo sounder surveys examining bottom type and macrophyte cover at two coastal marine finfish aquaculture sites in Canada. The dataset includes sidescan, video, and bathymetric data integrated into a GIS to assess benthic impacts and baseline conditions. It was published by Fisheries and Oceans Canada.

Use Cases

• Classify bottom type and macrophyte cover using integrated towfish and echo sounder data for benthic habitat mapping.
• Ground-truth echo sounder classifications with towfish video and sidescan data to improve habitat model accuracy.
• Analyze GIS layers to evaluate potential benthic impacts and baseline conditions for aquaculture site management.
• Assess spatial data for cage placement suitability at the Welch Cove and Jordan Bay aquaculture sites.

Strengths

• Data from two distinct coastal aquaculture sites in New Brunswick and Nova Scotia provides comparative potential.
• Multiple survey methods (towfish sidescan, towfish video, echo sounder) allow for data cross-validation.
• Data is integrated into a GIS, enabling spatial analysis for management questions.

Limitations

• Specific row counts, column counts, and sample sizes are unavailable, limiting assessment of analytical scope.
• The dataset's temporal coverage is a single snapshot from March 2019, lacking time-series data for change detection.
• Data availability across the listed file formats (HTML, ESRI REST, TIFF, CSV, FGDB/GDB) is not detailed.
