GLS tag deployments on Snow petrels (Pagodroma nivea) in 2011 and 2012 from Bechervaise Island, Mawson Coast and Filla Island, Rauer Group

GPS tag deployments on Snow petrels (Pagodroma nivea) in 2011 from Bechervaise Island, Mawson Coast and Filla Island, Rauer Group, as part of AAS project 2722.Identifying potential threats from a changing environment on snow petrel populations requires understanding key ecological processes and their driving factors. This project focuses on determining driving factors for the species' at-sea distribution and foraging habitat. The data will be linked to spatio-temporally coincident data of biological and physical characteristics of the ecosystem to develop explanatory models and, where possible, predictive models to explore the outcomes of plausible scenarios of future environmental change on snow petrel populations.Tags were deployed on Snow Petrels in the Mawson and Davis areas for tracking purposes. The types of tags used were BAS (British Antarctic Survey) geolocators (Mk18)The GLS data are in hexadecimal format, and will need appropriate software to interpret them.

2011年，研究人员在莫森海岸贝谢尔韦岛（Bechervaise Island）及劳尔群岛菲拉岛（Filla Island）的雪鹱（*Pagodroma nivea*）身上部署全球定位系统（GPS）跟踪标签，本项目为AAS（Australian Antarctic Survey）第2722号课题的组成部分。要识别环境变化对雪鹱种群构成的潜在威胁，需明晰其核心生态过程及驱动因子。本项目旨在明确该物种海上分布与觅食栖息地的驱动因素。
本研究将把该数据集与生态系统生物及物理特征的时空匹配数据相结合，构建解释性模型；在条件允许的前提下，进一步构建预测模型，以探究未来环境变化的合理情景对雪鹱种群产生的影响。
研究人员还在莫森与戴维斯科考区域的雪鹱身上部署了跟踪标签以用于行为追踪，所用标签为英国南极调查局（BAS, British Antarctic Survey）生产的Mk18型地理定位器（geolocators）。
该地理定位数据（GLS）采用十六进制格式，需借助专用软件进行解析。
