Locations of cavity nesting species (snow petrels or Wilsons storm petrels), Mawson and Davis Regions

This dataset contains the locations of plots where cavity nesting species (snow petrels or Wilsons storm petrels) were found to be present in surveys of cavity nesting species in the Mawson region in 2010-11 and the Davis region in 2015-16, 2016-17 and 2017-18, plus records of the locations of cavity nesting birds seen outside plots. These data will be used by the AADC to show seabird presence on maps. For most locations the nests were found via a structured survey, using a GPS to find a random 50x50m plot, then manual searching of the plot by a ground observer. In addition, some locations were also found while walking between plots. Plots were not revisited in subsequent survey years.

本数据集收录了2010-2011年莫森（Mawson）区域、2015-2016、2016-2017及2017-2018年戴维斯（Davis）区域的洞巢鸟类（cavity nesting species，即雪鹱或威尔逊风暴海燕）专项调查中，确认有该类物种分布的样地位置，同时包含样地外观测到的洞巢鸟类的位置记录。该数据集将由澳大利亚南极数据中心（Australian Antarctic Data Centre, AADC）用于绘制海鸟分布地图。绝大多数样地的巢址通过标准化调查流程获取：借助全球定位系统（GPS）定位随机50米×50米样地，随后由地面观测人员对该样地开展人工搜寻。另有部分样地位置是在跨样地行进过程中偶然发现的。后续各调查年度均未对已记录样地进行重访。
