Near-seafloor drift transect video imagery and high-resolution digital still images from a 2023 survey in support of Marine Protected Area monitoring of St. Anns Bank, Atlantic Canada

Description

Funded under DFO's Marine Conservation Targets Program, this optical imagery benthic survey captured 16 drift-camera transects in the St. Anns Bank Marine Protected Area (MPA - 4364 km2) and 2 coastal transects west of the MPA, Atlantic Canada from August 15-23, 2023. High-resolution still images (n=1941) were taken periodically throughout each transect, while continuous high-definition downward- (~9 hours) and forward-facing (~8.5 hours) video was collected simultaneously. Distance travelled and distance between still images (m) was calculated using ArcGIS tools. Field of view (FOV) was estimated by measuring the length and width of a subset of still images (n=500) in ImageJ2, using 10-cm lasers for scale. FOV was standardized for each reported altitude. Transects ranged from 754 m to 2.8 km in length (~22 km surveyed in total), collecting imagery for 20 minutes to just over 1 hour at a time, surveying depths from 17 to 144 m below chart datum. Transect locations were selected based on unique bathymetric features and benthoscapes as well as areas previously surveyed in 2015. Cite this data as: Lawton P, Teed L.
