Resolving the annual pelagic distribution of Tufted Puffins in Alaska 2018-2021: unprocessed geolocator data

This dataset consists of the unprocessed time-stamped tab delimited ASCII files downloaded directly from geolocator devices (Migrate Technology, UK; n = 42) recovered from tufted puffins breeding on Middleton Island, Alaska. We deployed 60 geolocators over 2 years (30 each in July 2018 and 2019) on adult tufted breeding on Middleton Island. Forty-two geolocators were retrieved when birds returned to breed in subsequent summers (June 2019 [16], 2020 [24], and 2021 [2]). Data were downloaded using the Intigeo-IF interface for PC/laptop running Microsoft Windows. Each geolocator download typically consists of five files: light data (.lux; 2 files), temperature data (.sst; 1 file), and wet/dry data (.deg; 2 files). When geolocators failed prior to retrieval, they were sent to Migrate Technology for data extraction. These geolocators typically have 3 associated files: light data (.lux; 1 file); temperature data (.sst; 1 file), and wet/dry data (.deg; 1 file). Files from each geolocator are organized within a folder labeled for the year in which the device was retrieved (2019, 2020, or 2021) and subfolders labeled with the device serial number (e.g., BP574).

本数据集包含直接从地理定位设备（Migrate Technology，英国；n=42）下载的未处理、带时间戳的制表符分隔ASCII文件，这些设备从在阿拉斯加州米德尔顿岛繁殖的簇羽海鹦身上回收。我们在2年间（2018年7月和2019年7月各部署30台）于米德尔顿岛的成年繁殖簇羽海鹦身上安装了60台地理定位设备。其中42台地理定位设备在后续夏季（2019年6月回收16台、2020年回收24台、2021年回收2台）海鹦返回繁殖种群时被取回。数据通过适配运行Microsoft Windows操作系统的PC或笔记本电脑的Intigeo-IF接口完成下载。单台地理定位设备的下载数据通常包含5个文件：光照数据（.lux；2个文件）、温度数据（.sst；1个文件）以及干湿状态数据（.deg；2个文件）。若地理定位设备在回收前发生故障，则将其送往Migrate Technology进行数据提取。此类故障设备通常仅附带3个文件：光照数据（.lux；1个文件）、温度数据（.sst；1个文件）以及干湿状态数据（.deg；1个文件）。每台地理定位设备的相关文件均按层级文件夹组织：以设备回收年份（2019、2020或2021）命名父文件夹，再以设备序列号（例如BP574）命名对应子文件夹。
