资源简介：
Adelie colony boundaries at Welch Island were mapped on the 30 Nov 2014 to provide a boundary for the pole camera survey. Subcolonies were mapped by circumnavigating the perimeter on foot while carrying a Garmin GPS (Legend and Etrex30) to record the track. When mapping the perimeter of the subcolonies a buffer distance of approximately 2.5 meters was maintained between the mapper and the breeding birds.
This buffer distance was reduced by .5m to between 2m in the final shapefiles.
