Adélie penguin occupancy survey of the Kista Island Group, 2015

Seven colonies with breeding Adélie colonies were mapped this season in the Kista Island group between the 17th and 27th of November 2015. Subcolonies were mapped by circumnavigating the perimeter on foot while carrying a Garmin GPS (Etrex30) to record the track.When mapping the perimeter of the subcolonies, generally an average buffer distance of 2.5 meters was maintained between the mapper and breeding birds. However on Klung Island one of the mappers was mapping at a distance between 3 and 5m. Buffer distances were reduced accordingly for the varying tracks to produce a combined average buffer distance of 2m in the final layer. Given this the boundary mapping for these two islands may vary in accuracy. Note when mapping was undertaken at Peterson Island (74507) two subcolonies were not mapped when compared to mapping in the 13/14 season. The larger of these colonies was missed but the smaller colony did not exist in the 15/16 season.Please refer to the Seabird Conservation Team Data Sharing Policy for use, acknowledgement and availability of data prior to downloading data.

本季（2015年11月17日至27日）于基斯塔群岛（Kista Island group）完成了7处阿德利企鹅（Adélie）繁殖集群的测绘工作。次级繁殖集群的测绘采用徒步环绕边界的方式完成，作业期间携带佳明（Garmin）Etrex30型GPS设备记录行进轨迹。测绘次级集群边界时，测绘人员与繁殖企鹅之间通常保持平均2.5米的缓冲距离。但在克伦岛（Klung Island）上，有一名测绘人员的作业距离为3至5米。针对不同的行进轨迹，我们相应调整了缓冲距离，最终在生成的成果图层中，综合平均缓冲距离为2米。因此，这两座岛屿的边界测绘精度或存在差异。需注意：相较于2013/2014赛季的测绘结果，本次在彼得森岛（Peterson Island，编号74507）的作业中，有2处次级繁殖集群未被测绘。其中规模较大的集群系漏测，而规模较小的集群在2015/2016赛季已不复存在。下载数据前，请参阅《海鸟保护团队数据共享政策》以了解数据使用、引用及获取方式。
