Figure Lengend Snippet: Equipment and camera specification for potential instrument-based surveys for polar bears and seals in the eastern Chukchi Sea. As with previous IBS surveys in the Bering Sea, a DeHavilland DHC-6 Twin Otter aircraft ( a ) would be equipped with three long wavelength infrared (LWIR) thermal cameras (FLIR SC645) and three high-resolution digital single-lens reflex (SLR) cameras (Canon 1Ds Mark III) mounted through its bellyport ( b ). Blue lines ( c ) indicate thermal camera swath width for each camera, while red and green polygons represent the expected footprint of SLR photographs. Flying at a target altitude of 300 m, this configuration results in a thermal swath width of 470 m of which automated digital photographs cover ca 84%.
