    • Arctic Aerial Calibration Experiments (ACEs), Beaufort Sea, 2015

    Metadata Updated: June 1, 2025

    The Arctic Aerial Calibration Experiments (ACEs) study was designed to evaluate the ability of UAS technology (i.e., airframe, payloads, sensors, and software) to detect cetaceans, identify individuals to species, estimate group size, identify calves, and estimate density in arctic waters, relative to conventional aerial surveys conducted by human observers in fixed wing aircraft and to photographic strip transect data collected from the manned aircraft. The ACEs’ imagery described here was collected and analyzed in order to conduct a 3-way comparison of data and derived statistics from the following:
    • Observers in the manned aircraft; • Digital photographs from cameras mounted to the manned aircraft; • Digital photographs from cameras mounted to the Unmanned Aerial Vehicle (UAV).

    Lineage The UAS flight team conducted flights of the ScanEagle® and the ASAMM manned aerial survey team conducted flights in a Turbo Commander 690A aircraft on 5 days during the study. Digital images were collected using Nikon D810 DSLRs, a Nikkor 20mm lens, and a Zeiss 21mm lens. An image was taken every 3 seconds during each flight in order to ensure at least a 33% overlap between images at a survey altitude of 1050ft and a speed of 60 kts. Every 3rd image that fell within the study area was reviewed by a trained observer for the presence or absence of marine mammals, and every sighting was confirmed by a second trained observer. Metadata for the concurrent ASAMM survey can be found here: https://www.fisheries.noaa.gov/inport/item/17338.
