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 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月开展的一项栖息状况调查显示，诺克斯海岸（Knox Coast）沿线共有6座岛屿存在繁殖期阿德利企鹅（Adélie penguin）种群。2009/10年度的本次调查采用固定翼飞机执行，对已被企鹅占据的繁殖位点拍摄了倾斜航空照片。本次拍摄的航空照片已通过南极陆地卫星影像镶嵌图（Landsat Image Mosaic of Antarctica, LIMA）E157幅块的海岸线shapefile或卫星影像完成地理配准，企鹅群落的边界则从完成地理配准的照片中数字化提取。各岛屿详情如下：梅里特岛（Merrit）：照片拍摄于2010年2月1日，地理配准至LIMA幅块E157；纳特角（Cape Nutt）：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卫星影像；伊万诺夫海岬（Ivanoff Head）：照片拍摄于2009年12月27日，地理配准至LIMA幅块E157。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。
