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)
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.

Purpose | 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. |
