PLoS ONE 12(11): e0187465. https://doi.org/10.1371/journal.pone.0187465 https://doi.org/10.1371/journal.pone.0187465 We aerially surveyed leopard seals of known body size and mass to test the precision and accuracy of photogrammetry from a small UAS. Flights were conducted in January and February of 2013 and 2014 and 50 photogrammetric samples were obtained from 15 unrestrained seals. Photogrammetric measurements from a single, vertical image obtained using UAS provide a noninvasive approach for estimating the mass and body condition of pinnipeds that may be widely applicable. Measurements of body size and mass are fundamental to pinniped population management and research. Manual measurements tend to be accurate but are invasive and logistically challenging to obtain. Ground-based photogrammetric techniques are less invasive, but inherent limitations make them impractical for many field applications. The recent proliferation of unmanned aerial systems (UAS) in wildlife monitoring has provided a promising new platform for the photogrammetry of free-ranging pinnipeds. Leopard seals (Hydrurga leptonyx) are an apex predator in coastal Antarctica whose body condition could be a valuable indicator of ecosystem health. completed Krause, Douglas douglas.krause@noaa.gov pointOfContact Woodman, Sam 858-546-7138 8901 La Jolla Shores Dr La Jolla CA 92037 USA sam.woodman@noaa.gov custodian notPlanned AMLR Hydrurga leptonyx UAS cameras leopard seal morphometrics photogrammetry pinnipeds unmanned aerial system theme Austral Spring Austral Summer temporal Antarctic peninsula CCAMLR Area 48.1 Cape Shirreff FAO Area 48.1 Livingston Island South Shetland Islands place DOC/NOAA/NMFS/SWFSC > Southwest Fisheries Science Center, National Marine Fisheries Service, NOAA.
