Leopard seal geolocation and activity data from Bird Island, South Georgia, 2003 to 2013

These are light level and activity data collected from BAS geolocators that were deployed on 4 Leopard Seals hauled out on Bird Island, South Georgia. Tags were deployed between May 2003 and June 2013. One seal Y5282(B4942) was tracked during two non-consecutive years using two different identification flipper tags. There are three data types for each seal a) the unprocessed light sensor data b) the unprocessed activity (wet/dry) data and c) The estimated positions estimated using the BAStag and SGAT packages in R. All files are in the CSV format and each folder has a readme.txt file describing the data structure of the files within. The data are reported in detail in Staniland et al. 2018 'Long Term Movements and Activity Patterns of an Antarctic Marine Apex Predator: The Leopard Seal' PLOSone.

本数据集源自部署在南乔治亚州伯德岛上岸休憩的4只豹海豹身上的BAS地理定位器，采集内容为光照强度与活动数据。该批标记设备的部署时段为2003年5月至2013年6月。其中编号为Y5282(B4942)的豹海豹，佩戴两枚不同的鳍部识别标记，在两个非连续的年份中被追踪监测。每只豹海豹对应三类数据：a) 未经处理的光照传感器原始数据；b) 未经处理的活动（干湿状态）原始数据；c) 利用R语言中的BAStag与SGAT软件包估算得到的个体位置数据。所有数据文件均采用CSV格式存储，每个数据文件夹均附带readme.txt文件，用于说明该文件夹内数据文件的组织结构。该数据集的详细信息已由Staniland等人于2018年发表在《PLOS ONE》期刊的论文《Long Term Movements and Activity Patterns of an Antarctic Marine Apex Predator: The Leopard Seal》中进行了详细阐述。
