Snow Petrel nest locations collected around Casey station during February 2000 by Eric Woehler and Lee Belbin

The survey was completed as part of ASAC project 1219 (ASAC_1219) during February 2000 at Casey. Differentially corrected GPS data were collected for all snow petrel nests located during intensive searches of ice-free areas in the Casey station extended recreation area. 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.

本调查于2000年2月在凯西（Casey）科考站完成，隶属于ASAC项目1219（ASAC_1219）的研究范畴。研究人员对凯西站拓展娱乐区内的无冰区域开展了密集搜寻，对在此期间发现的所有雪鹱（snow petrel）巢穴采集了经过差分校正的GPS（Differentially corrected GPS）数据。项目1219的公开研究摘要显示：本项目收集了南极及亚南极海鸟的种群数据，可用于开展局地至区域尺度下的自然种群趋势评估，从而识别由站区活动、直升机作业等人为干扰引发的种群变化。
