Adelie 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 Adelie 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 E157
Cape Nutt: Photographs taken on 5 January 2010 and geo-referenced to a Quickbird satellite image taken on 17 February 2011
Ivanoff Head: Photographs taken on 27 December 2009 and geo-referenced to LIMA tile E157

2009年12月—2010年2月及2011年1月开展的阿德利企鹅（Adelie penguin）繁殖种群栖息调查显示，诺克斯海岸沿线共有6座岛屿存在繁殖种群。本次2009/2010年度调查采用固定翼飞机（fixed-wing aircraft）执行，对有企鹅栖息的区域拍摄了斜向航空摄影照片（oblique aerial photographs）。这些航空摄影照片已通过卫星图像或南极洲Landsat影像镶嵌图（Landsat Image Mosaic of Antarctica, LIMA）E157幅块的海岸线形状文件（shapefile）完成地理配准（geo-referenced），企鹅群落的边界则从完成地理配准的照片中数字化提取。

各岛屿的详细信息如下：
梅里特岛：照片拍摄于2010年2月1日，地理配准至LIMA E157幅块
纳特角：照片拍摄于2010年1月5日，地理配准至2011年2月17日获取的Quickbird卫星图像
伊万诺夫角：照片拍摄于2009年12月27日，地理配准至LIMA E157幅块
