GPS fixes for foraging Southern Giant Petrels (Macronectes giganteus) breeding in Nelson Island, Maritime Antarctic Peninsula, 2021 to 2023

This dataseta contain tracking data of breeding Southern Giant Petrels (<em>Macronectes giganteus</em>) collected from december to february in Harmony Point (Nelson Island, South Shetland Islands) in 2021/22 and 2022/23 breeding seasons. Cat-Log 2 (Perthold Engineering) and Sputnik (Sextant Technology) devices were used, consisting of 5-minute interval GPS fixes (a few animals had 10 minutes fixes, they are easy to spot by checking data). Capture and deployment followed protocols evaluated by ethical commitees of Universidad de Magallanes and Instituto Milénio of Biodiversity of Antarctic and Subantarctic Ecosystems (BASE), with environmental permits emmited by Instituto Antártico Chileno. Two files are available: one on .csv format, and another one in .Rds that can be opened in R maintaining data carachteristics, for instance, date (TS column) is in a POSIXct timpestamp format, and it is maintained within the file. Each animal was ringed with stainless steel rings; ring numbers correspond to the BirdId column. Production of this dataset was supported by the Instituto Antártico Chileno, Programa Áreas Marinas Protegidas (AMP 24 03 052), ANID – Programa Iniciativa Milenio – ICN2021_002 (BASE).本数据集收录了2021/2022及2022/2023繁殖季期间，于南设得兰群岛纳尔逊岛和谐角（Harmony Point）采集的繁殖期南方巨海燕（*Macronectes giganteus*）的追踪数据。本研究采用Cat-Log 2（Perthold Engineering公司）与Sputnik（Sextant Technology公司）定位设备，此类设备以5分钟间隔采集GPS定位点，仅少数研究个体采用10分钟间隔的采集模式，可通过查阅数据快速识别此类样本。捕获与设备部署流程均遵循麦哲伦大学（Universidad de Magallanes）及南极与亚南极生态系统生物多样性千年研究所（Instituto Milénio of Biodiversity of Antarctic and Subantarctic Ecosystems，简称BASE）伦理委员会审定的规范，并已获得智利南极研究所（Instituto Antártico Chileno）颁发的环境许可。本次数据集提供两份文件：其一为.csv格式，其二为.Rds格式，可在R软件中直接打开并保留完整数据属性——例如TS列的日期数据采用POSIXct时间戳格式，该格式属性将在文件中完整保留。所有研究个体均佩戴不锈钢脚环，脚环编号与数据集中的BirdId列一一对应。本数据集的制作得到智利南极研究所、海洋保护区计划（Programa Áreas Marinas Protegidas，编号AMP 24 03 052）以及ANID–千年启动计划–ICN2021_002（BASE项目）的资助。
