Adelie penguin occupancy survey of the Bolingen Island group, 2010

Occupancy surveys in November 2009 and December 2010 (Southwell and Emmerson 2013) found a total of 2 Adelie penguin breeding sites in the Bolingen Island group between longitudes 75.333oE-75.912oE. The boundaries of breeding sub-colonies at 1 of these sites (Lichen Island, 73030) were subsequently mapped from vertical aerial photographs taken for abundance surveys on 20 November 2010 (for details of aerial photography see Southwell et al. 2013). The boundaries were mapped with a buffer distance of approximately 1-3 m from the perimeter of penguin sub-colonies. The other breeding site (73156) was photographed obliquely from a helicopter using a hand-held camera on 6 December 2010. Colony boundaries for this site were drawn and digitised by eye.Please refer to the Seabird Conservation Team Data Sharing Policy for use, acknowledgement and availability of data prior to downloading data.

2009年11月与2010年12月的栖息地调查（Southwell与Emmerson，2013）在经度范围75.333°E~75.912°E的博林根群岛（Bolingen Island group）中共发现2处阿德利企鹅（Adélie penguin）繁殖位点。其中一处繁殖位点（利辰岛，编号73030）的繁殖亚群落边界，后续通过2010年11月20日为开展种群丰度调查所拍摄的垂直航空照片完成测绘（航空摄影细节详见Southwell等人2013年的研究）。该边界以距企鹅亚群落外围约1~3米的缓冲距离进行划定。另一处繁殖位点（编号73156）于2010年12月6日由搭载于直升机的手持相机拍摄斜向影像，其群落边界经人工目视绘制并数字化。请在下载数据前，参阅《海鸟保护团队数据共享政策》以了解数据的使用、引用及获取规则。
