Aerial Photography of first-year sea ice melt ponds for Arctic-ICE 2012

During each survey, an ¿X¿ pattern was flown over McDougall Sound at 1524 m (5000 ft), followed by a grid pattern over the primary field study site at 610 m (2000ft). On 02 July, the flight was extended to include coverage of region of older ice types to the north of Little Cornwallis Island and to coincide with a RADARSAT-2 pass over the area surveyed. A Canon G10 camera mounted to an open hatch in the rear of a twin otter acquired digital images at rates resulting in ~10% overlap, depending on ground speed and altitude variations. Image acquisition rates and camera settings were controlled using a laptop with the PSRemote camera capture software, allowing for adjustments due to ground speed and altitude variations. At 1542 m flying height, each captured image covered a swath of 1872 m with a pixel size estimated at 0.54 m; at 610 m flying height the swath was 749 m and the pixel size 0.22 m. Images have been stored in ".tiff" format for further processing (feature extraction).
