Cape petrel nesting areas on islands off the Vestfold Hills, November 2017

The dataset contains boundaries of Cape petrel nesting areas at numerous breeding sites on islands off the Vestfold Hills, Antarctica. Boundaries of nesting sites were obtained from aligning ground observations and photographs from land or the sea-ice adjacent to the breeding sites onto maps of islands in the region. The observations were made and the photographs taken between 18 and 30 November 2017. Marcus Salton and Kim Kliska made the ground observations, took the photographs and delineated the GIS boundaries representing the nesting areas.
The data is a polygon shapefile with each polygon designated Type A or Type B. Type A indicates nests present. Type B indicates this area was searched and no nests were present.
Also included are three images showing the Type A polygons and the associated nest counts.

本数据集包含南极维斯特福尔丘陵（Vestfold Hills）周边岛屿上多处繁殖地的海角海燕（Cape petrel）巢区边界。巢区边界通过将地面观测数据与繁殖地附近陆地或海冰获取的影像，匹配至该区域岛屿地图后得到。观测与影像拍摄时间为2017年11月18日至30日。Marcus Salton与Kim Kliska完成了地面观测、影像拍摄，并绘制了代表巢区的地理信息系统（Geographic Information System，GIS）边界。
本数据集采用多边形形状文件（polygon shapefile）格式，每个多边形均标注为A型或B型：A型代表存在巢穴，B型代表该区域已完成搜索且未发现巢穴。
数据集同时包含三张展示A型多边形及其对应巢穴计数的影像。
