Northern fur seals data

Data was collected on northern fur seal females during the breeding season on St Paul island, Bering Sea, Alaska from a daily Diary tag from Wildlife Computers. Column headings include "Date", "Time","Depth", "External Temperature", "int mX", "int mY", "int mZ", "int aX", "int aY", "int aZ", "Light Level", "Velocity", "Wet/Dry", "Wet/Dry", "Hour", "Battery Voltage", "Protocol". int mX, Y, Z refer to magnetic field recorded on the 3 body axes, and int aX, Y, Z to the acceleration recorded on the same axes.本数据集采集自阿拉斯加白令海圣保罗岛繁殖季的雌性北方海狗，所用数据来自Wildlife Computers公司的日常记录标签（Daily Diary tag）。数据集的列字段包括：日期（Date）、时间（Time）、深度（Depth）、外部温度（External Temperature）、int mX、int mY、int mZ、int aX、int aY、int aZ、光照等级（Light Level）、速度（Velocity）、干湿状态（Wet/Dry）、干湿状态（Wet/Dry）、小时（Hour）、电池电压（Battery Voltage）、协议（Protocol）。其中int mX、mY、mZ指记录于3个身体轴向上的磁场数据，int aX、aY、aZ则对应相同轴向的加速度测量值。
