RT journal article T1 Assessing topographic features and population abundance in an Antarctic penguin colony through UAV-based deep-learning models A1 Belyaev, Oleg A1 Román, Alejandro A1 Belliure, Josabel A1 Navarro, Gabriel A1 Barbero González, Luis Carlos A1 Tovar Sánchez, Antonio A2 Ciencias de la Tierra K1 UAV K1 Deep-learning K1 Chinstrap penguin K1 Pygoscelis antarcticus K1 Breeding site features K1 Vapour col AB Penguins play an essential biochemical role in the Antarctic ecosystem, being the study of their dynamics ofutmost importance to understand their environment, behaviour and populational trends in the current climatechange scenario. In this study, we used multi-rotor Unmanned Aerial Vehicles (UAVs) along the coast of thechinstrap penguin (Pygoscelis antarcticus) colony of Vapour Col (Deception Island, Antarctica) to map potentialsites of biochemical interactions with the surrounding sea water. Several runoff discharge points were identified,where a precise placing of environmental sampling station is suggested. Additionally, UAVs were used incombination with Object Detection Architectures to obtain the chinstrap colony population size. Applying asimulation for clutch initiation dates due to our off-laying peak count, we obtained an estimated range of 13,250to 22,000 breeding pairs in the 2021/2022 breeding season, also suggesting an alternative approach usingchinstrap chicks as proxy to estimate adult numbers. This research shows the utility of UAV-deep learning forenvironment characterization and wildlife monitoring, providing a solid framework for upcoming studies in thearea.
