Bering-Okhotsk Seal Survey (BOSS) On-Effort Flight Tracks (2012-13)
Aerial surveys were flown during the spring of 2012 and 2013 as part of the Bering Okhotsk Seal Surveys (BOSS) project to gather data on distribution and abundance of ice-associated seals in the eastern Bering Sea. The distributions of these seals are broad and patchy, resulting in surveys that cover large areas and encounter rapidly changing environmental conditions. Surveys were flown using a fixed-wing aircraft with a paired system of digital cameras and thermal imagers operated by observers and mounted in the belly port. Flight tracks were recorded with an attitude and heading reference system (AHRS) that also recorded location information at one second intervals. A secondary flight track was recorded with a GPS which was used to supplement location information when there was a glitch with the AHRS. BOSS on-effort flight tracks were used to calculate total distance and area flown for estimating seal abundance, in addition to georeferencing digital and thermal imagery collected in flight. On-effort flight tracks (survey effort) were initially determined by the observer based on environmental conditions and later refined based on aircraft attitude and imagery review. The spatial data are provided in the geographic (epsg:4326) coordinate reference system.
