Photogrammetric Estimates of Mass and Body Condition of Leopard Seals in the Antarctic Using an Unmanned Aerial System from 2013-01-01 to 2014-03-31 (NCEI Accession 0168214)

Data provided by  National Oceanic and Atmospheric Administration

We aerially surveyed leopard seals of known body size and mass to test the precision and accuracy of photogrammetry from a small Unmanned Aerial System (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.
