Adélie penguin occupancy survey of the Lewis Islands, 2012

An occupancy survey in December 2009-February 2010 and January 2011 found a total of 6 islands along the Knox coast had populations of breeding Adélie penguins. The survey in 2009/10 was conducted from a fixed wing aircraft and oblique aerial photographs were taken of occupied sites. The aerial photographs were geo-referenced to satellite images or the coastline shapefile from the Landsat Image Mosaic of Antarctica (LIMA, tile E157) and the boundaries of penguin colonies were digitised from the geo-referenced photos. Details for each island are:Merrit: Photographs taken on 1 February 2010 and geo-referenced to LIMA tile E157Cape Nutt: Photographs taken on 5 January 2010 and geo-referenced to a Quickbird satellite image taken on 17 February 2011Ivanoff Head: Photographs taken on 27 December 2009 and geo-referenced to LIMA tile E157Please refer to the Seabird Conservation Team Data Sharing Policy for use, acknowledgement and availability of data prior to downloading data.

2009年12月至2010年2月及2011年1月开展的栖息调查显示，诺克斯海岸沿线共有6个岛屿存在繁殖期阿德利企鹅种群。

2009/10年度调查通过固定翼飞机开展，并对被企鹅占据的区域拍摄了倾斜航空照片。

这些航空照片与卫星图像或来自南极洲陆地卫星图像镶嵌图（LIMA，E157瓦片）的海岸线shapefile格式文件进行了地理配准，企鹅栖息地的边界则从配准后的照片中数字化提取。

各岛屿的详细信息如下：
