Near-seafloor drift transect video and high-resolution digital still imagery from a 2023 survey in the Quoddy Region of the lower, western Bay of Fundy

Near-seafloor drift transect video and high-resolution digital still imagery from a 2023 survey in the Quoddy Region of the lower, western Bay of Fundy Funded under DFO's Marine Conservation Targets Program, this optical imagery benthic survey captured 24 drift-camera transects from September 22-26, 2023 in the Quoddy Region of the lower, western Bay of Fundy, New Brunswick, Canada. The survey area includes Passamaquoddy Bay, the 'Head Harbour/West Isles Archipelago/The Passages' Ecologically and Biologically Significant Area (ESBA, ~113 km2), and Wolves Bank (a unique bathymetric feature south of the Wolves islands). High-resolution still images (n=1875) were taken periodically throughout each transect, while continuous high-definition downward- (>10 hours) and forward-facing (~10.5 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=343) in ImageJ2, using 10-cm lasers for scale. FOV was standardized for each reported altitude. Transects ranged from 133 m to 2.6 km in length (~18 km surveyed in total), collecting imagery continuously for 3 minutes to more than 1 hour at a time, surveying depths from 24 to 144 m below chart datum. Transect locations were selected based on unique bathymetric features as well as areas previously predicted to have high habitat suitability for vulnerable marine ecosystem species.
