Snow Petrel data collected around Casey Station during the summer of 2001/02 by Frederique Olivier and Eric Woehler.

The survey was completed as part of ASAC project 1219 (ASAC_1219) during 2001/02 summer at Casey. GPS data were collected for all snow petrel nests and wilson's storm petrel nests located during intensive searches of ice-free areas in the Windmill Islands. Approximately 20% of the ice-free areas were surveyed in this manner.Public summary for project 1219:This project provides population data on Antarctic and Subantarctic seabirds that permit assessments to be made of natural population trends at local to regional scales, so that changes in populations due to to human disturbance, such as station activities and helicopter operations can be identified.The data file includes two shapefiles, one with snow petrel nest sites and the other with wilson storm petrel nest sites.The metadata records linked at the provided URLs describe the collection of locations of snow petrel nests at Casey in 1998/99 and 1999/2000.

本调查系ASAC项目1219（ASAC_1219）的组成部分，于2001/02年夏季在凯西站（Casey）开展。研究人员对风车群岛（Windmill Islands）的无冰区域开展密集搜寻，针对搜寻过程中发现的全部雪海燕（snow petrel）巢穴与威尔逊风暴海燕（Wilson's storm petrel）巢穴采集了GPS定位数据，本次调查覆盖了约20%的无冰区域。

项目1219的公开概要如下：本项目提供南极及亚南极海鸟的种群数据，可用于评估局地至区域尺度的自然种群动态趋势，进而识别由人类干扰（如科考站作业与直升机作业）引发的种群变化。

本次数据集包含两个形状文件（shapefile）：其一收录雪海燕巢穴点位，其二收录威尔逊风暴海燕巢穴点位。
