Beluga and Vessel pixel location

Description

Pixel location (in x, y) of belugas, motoboats, kayaks, and paddleboard identified in photos. 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

Description

Pixel location (in x, y) of belugas or the center of a beluga group identified in photos at falling tide with vessels present. This csv file is used in conjunction with the Monte Carlo data code. Column descriptions: tide: Tide measurement in meters collected from the Canadian Hydrographic Service gauge (station 5010) measured to the closest 3m interval ID: unique identifying number for each beluga, group of belugas, or vessel ctide: Defines if the beluga was identified during rising, high, falling or low tide. FOV: The iteration of the camera field of view as identified in the supplemental materials of Ausen et al. 2022. PhotoO: The name of the photo where each beluga was identified Photo: The name of the photo without letters where each beluga was identified Date: Date photo was taken in YY-MM-DD (CDT) Time (CDT): Time the photo was taken in Central Daylight Time chat: Identifies if the pixel location is one of the following: one individual beluga (Beluga), a group of beluga (Bgroup), a motorboat tourist vessel (Motorboat), a kayak tourist vessel (Kayak), a paddleboard tourist vessel (Paddleboard), or a zodiac tourist vessel (Zodiac). x: gives the pixel location along the x axis in the photo for the beluga or group of beluga identified in the "chat" column y: gives the pixel location along the y axis in the photo for the beluga or group of beluga identified in the "chat" column
