These identify all individual beluga before they were categorized into groups. Column descriptions: Photo name: The name of the photo Camera Field of View: The iteration of the camera field of view as identified in the supplemental materials of Ausen et al. 2022. Date: Date photo was taken in YY-MM-DD (CDT) Time (CDT): Time the photo was taken in Central Daylight Time Tide: Tide measurement in meters collected from the Canadian Hydrographic Service gauge (station 5010) measured to the closest 3m interval Tide Cycle: Defines weather the photo was taken during rising, high, falling or low tide. Feature: What is identified within the photo, it can be a beluga, motorboat, paddleboard or kayak. None means none of the above were identified in the photo Location pixel x: gives the pixel location along the x axis in the photo for the feature identified in the feature column Location pixel y: gives the pixel location along the y axis in the photo for the feature identified in the feature column CSV text/csv 448478.0 Monte Carlo Code Created in Cran r version 4.1.1 using the tidyr and ggplot2 packages.
