Lineage | During 1998-2002, aerial survey observers used paper maps and/or rudimentary GPS units for in-flight navigation and data recording purposes. Photographs of seal haul-out sites were primarily taken with SLR cameras shooting on rolls of 35 mm film which were later processed as slides. Observers were instructed to record the location of new haul-out sites and note when no seals were seen at known haul-out sites (i.e., record "zero" counts); however, this was not done in every case. Seal counts were obtained by projecting slides on a white board and counting each individual as it was marked. Count data for each year were recorded in separate spreadsheet files. During 2004-2006, an effort was made to retroactively fill in missing "zero" counts by comparing observer's notes and GPS tracks against locations of known haul-out sites and photo counts to identify sites that likely had been surveyed but had no data recorded. Count records for each haul-out site were also associated with newly-developed spatial survey units which were designed to simplify the data collection and analysis processes for this project. Count data for all years were given additional QA/QC procedures and combined into a single Access database. |
